how does male gender reassignment surgery work

How Gender Reassignment Surgery Works (Infographic)

Bradley Manning, the U.S. Army private who was sentenced Aug. 21 to 35 years in a military prison for releasing highly sensitive U.S. military secrets, is seeking gender reassignment. Here’s how gender reassignment works:

Converting male anatomy to female anatomy requires removing the penis, reshaping genital tissue to appear more female and constructing a vagina.

An incision is made into the scrotum, and the flap of skin is pulled back. The testes are removed.

A shorter urethra is cut. The penis is removed, and the excess skin is used to create the labia and vagina.

People who have male-to-female gender-reassignment surgery retain a prostate. Following surgery, estrogen (a female hormone) will stimulate breast development, widen the hips, inhibit the growth of facial hair and slightly increase voice pitch.

Female-to-male surgery has achieved lesser success due to the difficulty of creating a functioning penis from the much smaller clitoral tissue available in the female genitals.

The uterus and the ovaries are removed. Genital reconstructive procedures (GRT) use either the clitoris, which is enlarged by hormones, or rely on free tissue grafts from the arm, the thigh or belly and an erectile prosthetic (phalloplasty).

Breasts need to be surgically altered if they are to look less feminine. This process involves removing breast tissue and excess skin, and reducing and properly positioning the nipples and areolae. Androgens (male hormones) will stimulate the development of facial and chest hair, and cause the voice to deepen.

Reliable statistics are extremely difficult to obtain. Many sexual-reassignment procedures are conducted in private facilities that are not subject to reporting requirements.

The cost for female-to-male reassignment can be more than $50,000. The cost for male-to-female reassignment can be $7,000 to $24,000.

Between 100 to 500 gender-reassignment procedures are conducted in the United States each year.

Charley's Gender-Confirmation Surgery

From a young age, Charley Burton knew that his body did not match his gender identity – a struggle he kept inside for 50 years. With the help of family nurse practitioner Reagan Thompson, FNP, MSN, RN, and a whole team of caring providers, Charley found a safe place to become his true self. View Charley's story transcript.

FTM Top Surgery

To give you a flatter chest, we’ll have to remove breast tissue. We might also need to move and shrink your areolas.

If you have smaller breasts, we can sometimes use liposuction, which doesn’t involve many incisions.

Larger breasts may require the “double incision” technique. This method saves the pectoralis major muscle, the most defining characteristic of a male chest.

Whatever your breast size, we will use the techniques that optimize the results.

FTM Bottom Surgery

We can give you male genitalia in two different ways:

• Phalloplasty creates a penis and urethra (to stand while urinating). We use tissue from your forearm or thigh. We do this in 2 stages.
• Metoidioplasty takes your existing genital tissue and makes it longer, turning it into a defined phallus. This needs only one surgery.

You may or may not want to also have an operation to remove your internal reproductive organs. A hysterectomy takes out your uterus, fallopian tubes, and ovaries.

Facial Masculinization

Through a combination of procedures, we can sculpt your chin, jaw, and cheeks to appear more masculine. We can also reshape your nose and make your Adam’s apple look bigger. We can use synthetic implants for this work.

What Is Transgender Affirming Surgery? (video)

Scripps plastic surgeon explains types of surgery and preparation.

Manish Champaneria, MD , a plastic surgeon at Scripps Clinic Del Mar and Scripps Clinic Rancho Bernardo explains the steps involved in preparing for gender confirmation surgery , and discusses male-to-female and female-to-male procedures.

Video transcript

How do you prepare for gender confirmation surgery.

First seek counsel with your endocrinologist or your family medicine doctor, as well as a mental health professional. That mental health professional can be a psychiatrist, a licensed social worker or a family medicine physician who specializes in mental health.

Once that’s done, then you visit with a surgeon who is capable and skilled in the art of transgender or gender confirmation surgery and take it from there.

What is top sex reassignment surgery?

Top sex reassignment surgery is also known as gender confirmation surgery. For our transgender male patients, that involves a mastectomy. For our transgender female patients, that means making a breast. And typically that’s a bilateral breast augmentation with implants or with fat.

What is transgender or gender confirmation plastic surgery?

Transgender surgery encompasses a lot of different types of surgery. It’s also known as gender confirmation surgery for our patients who are transitioning to become either male or female.

For patients who are transitioning to become female, that involves facial feminization. That means softening the contour of the face and giving a more feminine appearance. That also involves enhancing the breast with either an implant or with their own fat. For our patients who are becoming male, that involves a mastectomy where the breasts are removed and a masculinized chest is made.

Gender Confirmation Surgery

The University of Michigan Health System offers procedures for surgical gender transition.  Working together, the surgical team of the Comprehensive Gender Services Program, which includes specialists in plastic surgery, urology and gynecology, bring expertise, experience and safety to procedures for our transgender patients.

Access to gender-related surgical procedures for patients is made through the University of Michigan Health System Comprehensive Gender Services Program .

The Comprehensive Gender Services Program adheres to the WPATH Standards of Care , including the requirement for a second-opinion prior to genital sex reassignment.

Available surgeries:

Male-to-Female:  Tracheal Shave  Breast Augmentation  Facial Feminization  Male-to-Female genital sex reassignment

Female-to-Male:  Hysterectomy, oophorectomy, vaginectomy Chest Reconstruction  Female-to-male genital sex reassignment

Sex Reassignment Surgeries (SRS)

At the University of Michigan Health System, we are dedicated to offering the safest proven surgical options for sex reassignment (SRS.)   Because sex reassignment surgery is just one step for transitioning people, the Comprehensive Gender Services Program has access to providers for mental health services, hormone therapy, pelvic floor physiotherapy, and speech therapy.  Surgical procedures are done by a team that includes, as appropriate, gynecologists, urologists, pelvic pain specialists and a reconstructive plastic surgeon. A multi-disciplinary team helps to best protect the health of the patient.

For patients receiving mental health and medical services within the University of Michigan Health System, the UMHS-CGSP will coordinate all care including surgical referrals.  For patients who have prepared for surgery elsewhere, the UMHS-CGSP will help organize the needed records, meet WPATH standards, and coordinate surgical referrals.  Surgical referrals are made through Sara Wiener the Comprehensive Gender Services Program Director.

Male-to-female sex reassignment surgery

At the University of Michigan, participants of the Comprehensive Gender Services Program who are ready for a male-to-female sex reassignment surgery will be offered a penile inversion vaginoplasty with a neurovascular neoclitoris.

During this procedure, a surgeon makes “like become like,” using parts of the original penis to create a sensate neo-vagina. The testicles are removed, a procedure called orchiectomy. The skin from the scrotum is used to make the labia. The erectile tissue of the penis is used to make the neoclitoris. The urethra is preserved and functional.

This procedure provides for aesthetic and functional female genitalia in one 4-5 hour operation.  The details of the procedure, the course of recovery, the expected outcomes, and the possible complications will be covered in detail during your surgical consultation. What to Expect: Vaginoplasty at Michigan Medicine .

Female-to-male sex reassignment

At the University of Michigan, participants of the Comprehensive Gender Services Program who are ready for a female-to-male sex reassignment surgery will be offered a phalloplasty, generally using the radial forearm flap method. 

This procedure, which can be done at the same time as a hysterectomy/vaginectomy, creates an aesthetically appropriate phallus and creates a urethera for standing urination.  Construction of a scrotum with testicular implants is done as a second stage.  The details of the procedure, the course of recovery, the expected outcomes, and the possible complications will be covered in detail during your surgical consultation.

Individuals who desire surgical procedures who have not been part of the Comprehensive Gender Services Program should contact the program office at (734) 998-2150 or email [email protected] . W e will assist you in obtaining what you need to qualify for surgery.

The idea of getting stuck in the wrong body sounds like the premise for a movie in "Freaky Friday," a mother and a daughter swap bodies, and in "Big" and "13 Going on 30," teenagers experience life in an adult's body. These movies derive their humor from the ways in which the person's attitude and thoughts don't match their appearance. A teenager trapped in her mother's body, for example, revels in breaking curfew and playing air guitar, while a teenager trapped in an adult's body is astounded by the trappings of wealth that come with a full-time job. We laugh because the dialogue and actions are so contrary to what we'd expect from someone who is a mother, or from someone who is an employed adult.

But for some people, living as an incongruous gender is anything but a joke. A transgender person is someone who has a different gender identity than their birth sex would indicate. We interchange the words sex, sexuality and gender all the time, but they don't actually refer to the same thing. Sex refers to the parts we were born with; boys, we assume, have a penis, while girls come equipped with a vagina. Sexuality generally refers to sexual orientation , or who we're attracted to in a sexual and/or romantic sense. Gender expression refers to the behavior used to communicate gender in a given culture. Little girls in the U.S., for example, would be expected express their feminine gender by playing with dolls and wearing dresses, and little boys would be assumed to express their masculinity with penchants for roughhousing and monster trucks. Another term is g ender identity, the private sense or feeling of being either a man or woman, some combination of both or neither [source: American Psychological Association ].

Sometimes, a young boy may want to wear dresses and have tea parties, yet it's nothing more than a phase that eventually subsides. Other times, however, there is a longing to identify with another gender or no gender at all that becomes so intense that the person experiencing it can't function anymore. Transgender is an umbrella term for people who identify outside of the gender they were assigned at birth and for some gender reassignment surgeries are crucial to leading a healthy, happy life.

Gender Dysphoria: Diagnosis and Psychotherapy

Real-life experience, hormone replacement therapy, surgical options: transgender women, surgical options: transgender men, gender reassignment: regrets.

Transgender people may begin identifying with a different gender, rather than the one assigned at birth, in early childhood, which means they can't remember a time they didn't feel shame or distress about their bodies. For other people, that dissatisfaction with their biological sex begins later, perhaps around puberty or early adulthood, though it can occur later in life as well.

It's estimated that about 0.3 percent of the U.S. population self-identify as transgender, but not all who are transgender will choose to undergo a gender transition [source: Gates ]. Some may choose to affirm their new gender through physically transforming their bodies from the top down, while others may prefer to make only certain cosmetic changes, such as surgeries to soften facial features or hair removal procedures, for example.

Not all who identify with a gender different than their birth sex suffer from gender dysphoria or go on to seek surgery. Transgender people who do want gender reassignment surgery, however, must follow the standards of care for gender affirmation as defined by the World Professional Association for Transgender Health (WPATH).

In 1980, when gender identity disorder (GID) was first recognized, it was considered a psychiatric disorder. In 2013, though, GID was, in part, reconsidered as biological in nature, and renamed gender dysphoria . It was reclassified as a medical condition in the American Psychological Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-V), a common language and standards protocol manual for the classification of mental disorders. With this classification, transgender people must be diagnosed prior to any treatment [source: International Foundation for Gender Education ].

Gender dysphoria is diagnosed when a person has a persistent desire to become a different gender. The desire may manifest itself as disgust for one's reproductive organs, hatred for the clothing and other outward signs of one's given gender, and/or a desire to act and be recognized as another gender. This desire must be continuously present for six months in order to be recognized as a disorder [source: WPATH].

In addition to receiving the diagnosis from a mental health professional, a person seeking reassignment must also take part in psychotherapy. The point of therapy isn't to ignite a change, begin a conversion or otherwise convince a transgender person that it's wrong to want to be of a different gender (or of no specific gender at all) . Rather, counseling is required to ensure that the person is realistic about the process of gender affirmation and understands the ramifications of not only going through with social and legal changes but with permanent options such as surgery. And because feeling incongruous with your body can be traumatizing and frustrating, the mental health professional will also work to identify any underlying issues such as anxiety, depression, substance abuse or borderline personality disorder.

The mental health professional can also help to guide the person seeking gender reassignment through the next step of the process: real-life experience.

WPATH requires transgender people desiring gender reassignment surgery to live full-time as the gender that they wish to be before pursuing any permanent options as part of their gender transition. This period is a known as real-life experience (RLE) .

It's during the RLE that the transgender person often chooses a new name appropriate for the desired gender, and begins the legal name-change process. That new name often comes with a set of newly appropriate pronouns, too; for example, when Chastity Bono, biologically born as Sonny and Cher's daughter in 1969, began her transition in 2008 she renamed herself as Chaz and instructed people to use "he" rather than "she" [source: Donaldson James ].

In addition to a new name and pronouns, during this time gender-affirming men and women are expected to also adopt the clothing of their desired gender while maintaining their employment, attending school or volunteering in the community. Trans women might begin undergoing cosmetic procedures to rid themselves of body hair; trans men might take voice coaching in attempt to speak in a lower pitch. The goal of real-life experience is to expose social issues that might arise if the individual were to continue gender reassignment. How, for example, will a boss react if a male employee comes to work as a female? What about family? Or your significant other? Sometimes, during RLE people realize that living as the other gender doesn't bring the happiness they thought it would, and they may not continue to transition. Other times, a social transition is enough, and gender reassignment surgery isn't pursued. And sometimes, this test run is the confirmation people need to pursue physical changes in order to fully become another gender.

In addition to the year-long real-life experience requirement before surgical options may be pursued, WPATH recommends hormonal therapy as a critical component to transitioning before surgery. Candidates for hormone therapy may choose to complete a year-long RLE and counseling or complete six months of a RLE or three-months of a RLE/three months of psychotherapy before moving ahead with hormone therapy.

Upon successfully completing a RLE by demonstrating stable mental health and a healthy lifestyle, the transitioning individual becomes eligible for genital reconstructive surgery — but it can't begin until a mental health professional submits a letter (or letters) of recommendation indicating that the individual is ready to move forward [source: WPATH].

Hormone replacement therapy (HRT) , also called cross-sex hormones, is a way for transgender individuals to feel and look more like the gender they identify with, and so it's a major step in gender reassignment. In order to be eligible for hormone therapy, participants must be at least 18 years old (though sometimes, younger adolescents are allowed to take hormone blockers to prohibit their naturally occurring puberty) and demonstrate to a mental health professional that they have realistic expectations of what the hormones will and won't do to their bodies. A letter from that mental health professional is required, per the standards of care established by WPATH.

Hormone therapy is used to balance a person's gender identity with their body's endocrine system. Male-to-female candidates begin by taking testosterone-blocking agents (or anti-androgens ) along with female hormones such as estrogen and progesterone . This combination of hormones is designed to lead to breast growth, softer skin, less body hair and fewer erections. These hormones also change the body by redistributing body fat to areas where women tend to carry extra weight (such as around the hips) and by decreasing upper body strength. Female-to-male candidates begin taking testosterone , which will deepen the voice and may cause some hair loss or baldness. Testosterone will also cause the clitoris to enlarge and the person's sex drive to increase. Breasts may slightly shrink, while upper body strength will increase [source: WPATH].

It usually takes two continuous years of treatment to see the full results of hormone therapy. If a person were to stop taking the hormones, then some of these changes would reverse themselves. Hormone therapy is not without side effects — both men and women may experience an increased risk for cardiovascular disease, and they are also at risk for fertility problems. Some transgender people may choose to bank sperm or eggs if they wish to have children in the future.

Sometimes hormonal therapy is enough to make a person feel he or she belongs to the desired gender, so treatment stops here. Others may pursue surgical means as part of gender reassignment.

Surgical options are usually considered after at least two years of hormonal therapy, and require two letters of approval by therapists or physicians. These surgeries may or may not be covered by health insurance in the U.S. — often only those that are considered medically necessary to treat gender dysphoria are covered, and they can be expensive. Gender reassignment costs vary based on each person's needs and desires; expenses often range between $7,000 and $50,000 (in 2014), although costs may be much greater depending upon the type (gender reconstructive surgeries versus cosmetic procedures) and number of surgeries as well as where in the world they are performed [source: AP ].

Gender affirmation is done with an interdisciplinary team, which includes mental health professionals, endocrinologists, gynecologists, urologists and reconstructive cosmetic surgeons.

One of the first surgeries male-to-female candidates pursue is breast augmentation, if HRT doesn't enlarge their breasts to their satisfaction. Though breast augmentations are a common procedure for cisgender women (those who identify with the gender they were assigned at birth), care must be taken when operating on a biologically male body, as there are structural differences, like body size, that may affect the outcome.

The surgical options to change male genitalia include orchiectomy (removal of the testicles), penile inversion vaginoplasty (creation of a vagina from the penis), clitoroplasty (creation of a clitoris from the glans of the penis) and labiaplasty (creation of labia from the skin of the scrotum) [source: Nguyen ]. The new vagina, clitoris and labia are typically constructed from the existing penile tissue. Essentially, after the testicles and the inner tissue of the penis is removed and the urethra is shortened, the skin of the penis is turned inside out and fashioned into the external labia and the internal vagina. A clitoris is created from excess erectile tissue, while the glans ends up at the opposite end of the vagina; these two sensitive areas usually mean that orgasm is possible once gender reassignment is complete. Male-to-female gender reconstructive surgery typically takes about four or five hours [source: University of Michigan ]. The major complication from this surgery is collapse of the new vaginal cavity, so after surgery, patients may have to use dilating devices.

Trans women may also choose to undergo cosmetic surgeries to further enhance their femininity. Procedures commonly included with feminization are: blepharoplasty (eyelid surgery); cheek augmentation; chin augmentation; facelift; forehead and brow lift with brow bone reduction and hair line advance; liposuction; rhinoplasty; chondrolargynoplasty or tracheal shave (to reduce the appearance of the Adam's apple); and upper lip shortening [source: The Philadelphia Center for Transgender Surgery]. Trans women may pursue these surgeries with any cosmetic plastic surgeon, but as with breast augmentation, a doctor experienced with this unique situation is preferred. One last surgical option is voice modification surgery , which changes the pitch of the voice (alternatively, there is speech therapy and voice training, as well as training DVDs and audio recordings that promise the same thing).

Female-to-male surgeries are pursued less often than male-to-female surgeries, mostly because when compared to male-to-female surgeries, trans men have limited options; and, historically, successful surgical outcomes haven't been considered on par with those of trans women. Still, more than 80 percent of surgically trans men report having sexual intercourse with orgasm [source: Harrison ].

As with male-to-female transition, female-to-male candidates may begin with breast surgery, although for trans men this comes in the form of a mastectomy. This may be the only surgery that trans men undergo in their reassignment, if only because the genital surgeries available are still far from perfect. Forty percent of trans men who undergo genital reconstructive surgeries experience complications including problems with urinary function, infection and fistulas [sources: Harrison , WPATH].

Female-to-male genital reconstructive surgeries include hysterectomy (removal of the uterus) and salpingo-oophorectomy (removal of the fallopian tubes and ovaries). Patients may then elect to have a metoidioplasty , which is a surgical enlargement of the clitoris so that it can serve as a sort of penis, or, more commonly, a phalloplasty . A phalloplasty includes the creation of a neo-phallus, clitoral transposition, glansplasty and scrotoplasty with prosthetic testicles inserted to complete the appearance.

There are three types of penile implants, also called penile prostheses: The most popular is a three-piece inflatable implant, used in about 75 percent of patients. There are also two-piece inflatable penile implants, used only 15 percent of the time; and non-inflatable (including semi-rigid) implants, which are used in fewer than 10 percent of surgeries. Inflatable implants are expected to last about five to 10 years, while semi-rigid options typically have a lifespan of about 20 years (and fewer complications than inflatable types) [source: Crane ].

As with trans women, trans men may elect for cosmetic surgery that will make them appear more masculine, though the options are slightly more limited; liposuction to reduce fat in areas in which cisgender women i tend to carry it is one of the most commonly performed cosmetic procedures.

As surgical techniques improve, complication rates have fallen too. For instance, long-term complication risks for male-to-female reconstructive surgeries have fallen below 1 percent. Despite any complications, though, the overwhelming majority of people who've undergone surgical reconstruction report they're satisfied with the results [source: Jarolím ]. Other researchers have noted that people who complete their transition process show a marked improvement in mental health and a substantial decrease in substance abuse and depression. Compare these results to 2010 survey findings that revealed that 41 percent of transgender people in the U.S. attempted suicide, and you'll see that finally feeling comfortable in one's own skin can be an immensely positive experience [source: Moskowitz ].

It's difficult, though, to paint a complete picture of what life is like after people transition to a new gender, as many people move to a new place for a fresh start after their transition is complete. For that reason, many researchers, doctors and therapists have lost track of former patients. For some people, that fresh start is essential to living their new lives to the fullest, while others have found that staying in the same job, the same marriage or the same city is just as rewarding and fulfilling and vital to their sense of acceptance.

In many ways, the process of gender affirmation is ongoing. Even after the surgeries and therapies are complete, people will still have to deal with these discrimination issues. Transgender people are often at high risk for hate crimes. Regular follow-ups will be necessary to maintain both physical and mental health, and many people continue to struggle with self-acceptance and self-esteem after struggling with themselves for so long. Still, as more people learn about gender reassignment, it seems possible that that these issues of stigma and discrimination won't be so prevalent.

As many as 91 percent Americans are familiar with the term "transgender" and 76 percent can correctly define it; 89 percent agree that transgender people deserve the same rights, privileges and protections as those who are cisgender [source: Public Religion Research Institute ]. But that's not to say that everything becomes completely easy once a person transitions to his or her desired gender.

Depending upon where you live, non-discrimination laws may or may not cover transgender individuals, so it's completely possible to be fired from one's job or lose one's home due to gender expression. Some people have lost custody of their children after divorces and have been unable to get courts to recognize their parental rights. Historically, some marriages were challenged — consider, for example, what happens when a man who is married to a woman decides to become a woman; after the surgery, if the two people decide to remain married, it now appears to be a same-sex marriage, which is now legalized in the U.S. Some organizations and governments refuse to recognize a person's new gender unless genital reconstructive surgery has been performed, despite the fact that some people only pursue hormone therapy or breast surgery [sources: U.S. Office of Personnel Management , Glicksman ].

Lots More Information

Author's note: stages of gender reassignment.

It's interesting how our terminology changes throughout the years, isn't it? (And in some cases for the better.) What we used to call a sex change operation is now gender realignment surgery. Transsexual is now largely replaced with transgender. And with good reason, I think. Knowing that sex, sexuality and gender aren't interchangeable terms, updating "sex change" to "gender reassignment" or "gender affirmation" and "transsexual" to "transgender" moves the focus away from what sounds like something to do with sexual orientation to one that is a more accurate designation.

Here’s how sex reassignment surgery works

In this excellent post , my colleague Steven Petrow advised that if you're wondering whether someone you know is transitioning from one gender to the other, it's best to "check your curiosity and hold your tongue." But we all have questions about a subject that is increasingly mainstream. Aside from the recent coverage of Bruce Jenner 's  apparent transition , Laverne Cox last year became the first trans person on the cover of Time magazine, and Amazon debuted “Transparent,” a show about a father who is transitioning.

[UPDATE:  Bruce Jenner: ‘Call me Caitlyn’ ]

Here are answers to some of the questions surrounding this issue.

How many people are transgender?

The Williams Institute, a think tank at the UCLA School of Law dedicated to research on sexual orientation law and public policy, estimates that 700,000 Americans are transgender . But a good piece last year on fivethirtyeight.com noted that there are no national surveys. And if there were, there is no agreement on what "trangender" means.

How many people have sex reassignment surgery?

It's very difficult to know. The Encyclopedia of Surgery says that "the number of gender reassignment procedures conducted in the United States each year is estimated at between 100 and 500. The number worldwide is estimated to be two to five times larger." At least one other researcher says there are many more. Marci Bowers, a transgender obstetrician and gynecologist in Burlingame, Calif., who performs the surgeries, said in an interview that she does about 200 per year herself, about three quarters of them male to female.

Fred Ettner, a physician in Evanston, Ill., who works with people going through transition, estimated that only about 25 percent to 30 percent of transgender people have any kind of surgery.

How does one begin the process of changing one's sex?

Under the standards of care adopted by the World Professional Association for Transgender Health (WPATH), the first step usually is meeting with a mental health professional for a diagnosis and psychotherapy. A diagnosis of gender identity disorder or gender dysphoria and a letter of recommendation from the therapist allows a person to begin hormone therapy with a doctor. That is usually followed by a period of living publicly as a member of the opposite sex and, finally, surgery to alter the genitalia and other body parts.

What do hormones do?

Androgens are given to women to help them develop secondary male sex characteristics such as a beard and body hair. Estrogen and anti-androgens are given to men to help change their musculature, skin and fat distribution, all of which will make them appear more feminine. Body hair also diminishes.

But Ettner said the hormones' most important contribution is to reduce the dysphoria transgender people have been struggling with all their lives. After a month or two, their bodies and brains begin aligning.

"It's very obvious to the individuals," Ettner said, adding, "Their brain finally is getting this hormone. They feel differently. They behave differently.

"The first effect is the brain effect," he said.

What is the Real-Life Experience (also known as the Real-Life Test)

Surgeons who follow the WPATH standards of care (which some patients and experts consider too strict) usually require candidates for surgery to live for as long as a year in their preferred gender role. They must work or go to school; do volunteer work; change their first names and prove to the surgeon that people other than their therapists know they are successfully living this way.

What happens during surgery?

Male to female genital surgery is easier, less expensive and generally more successful than female to male surgery. That's one reason why fewer women choose to have surgery on their genitals, Bowers said. (Another is cost.)

In male to female surgery , the testicles and most of the penis are removed and the urethra is cut shorter. Some of the skin is used to fashion a largely functional vagina. A "neoclitoris" that allows sensation can be created from parts of the penis. Men retain their prostates.

In female to male surgery, the breasts, uterus and ovaries are removed (in two separate procedures). A "neophallus" can be constructed using tissue from the forearm or other parts of the body that allows sexual sensation, an expensive procedure. Extending the urethra to allow standing urination has proved to be perhaps the most difficult part of the process, Bowers said.

What other kinds of surgery are performed?

Women wishing to live as men often have mastectomies. Men transitioning to women can have plastic surgery to "feminize" their appearance, including work on their eyes, noses, brows, chins and hairlines. They also can have their Adam's apple shaved down so it is less prominent.

Sounds expensive. Is it covered by insurance?

Bowers and Ettner said a woman who chooses the full range of surgical procedures available would spend $75,000 or more to transition to a male. Switching from male to female might cost in the $40,000 to $50,000 range. Some people have the work done in Thailand, which is well known for the surgery and where the cost is much lower.

Insurance is just beginning to cover some of the costs. Last year, Medicare lifted a 33-year ban on coverage for gender reassignment surgery , and the surgery was performed on 74-year-old Army veteran .

Do many people regret having the surgery?

Anecdotal accounts of regret abound, but overall it appears to be rare. Bowers said that only two of the 1,300 people she has operated on have wanted to go back to their old bodies.

But that doesn't mean that surgery is a miracle cure for the difficulties of gender dysphoria. People who make the transition often lose spouses, families, friends and jobs. They may find themselves completely alone if they relocate to start new lives. Johns Hopkins University, which in the 1960s was one of the first medical institutions to perform sex reassignment surgery, halted the practice when officials concluded that it was not helping the transgendered overall.

A 2o11 study of 324 Swedish transsexuals by the Karolinska Institute showed that "after sex reassignment, [they] have considerably higher risks for mortality, suicidal behaviour, and psychiatric morbidity than the general population. Our findings suggest that sex reassignment, although alleviating gender dysphoria, may not suffice as treatment for transsexualism, and should inspire improved psychiatric and somatic care after sex reassignment for this patient group."
