Around 1 in 5 vaginoplasty surgeries lead to corrective surgery.

A systematic review [1] of neo-vagina surgeries found a re-operation rate of 21.7% for non-esthetic reasons.

A Brazilian paper [2] found a somewhat lower, but similar, reoperation rate of 16.8%.

Female-to-male genital reconstruction surgery has a high negative outcome rate, including urethral compromise and worsened mental health.

The results of a 2021 international survey [1] of 129 female-to-male patients who underwent genital reconstruction surgery support anecdotal reports that complication rates following genital reconstruction are higher than are commonly reported in the surgical literature. 

Complication rates, including urethral compromise, and worsened mental health outcomes remain high for gender affirming penile reconstruction. In total, the 129 patients reported 281 complications requiring 142 revisions.

Another paper [2] found a 70% complication rate in one type of female-to-male genital reconstruction surgery.

Even with the “radial forearm free flap” method of creating a synthetic penis — “considered by many as the gold standard for phalloplasty” [3] — there are high rates of complications, with up to 64% urethroplasty related complications [4].

    Medical transition puts both males and females at risk of infertility.

    A wide-ranging study [1] found that gender-related drug regimens place patients at risk of infertility:

    Suppression of puberty with gonadotropin-releasing hormone agonist analogs (GnRHa) in the pediatric transgender patient can pause the maturation of germ cells, and thus, affect fertility potential. Testosterone therapy in transgender men can suppress ovulation and alter ovarian histology, while estrogen therapy in transgender women can lead to impaired spermatogenesis and testicular atrophy. The effect of hormone therapy on fertility is potentially reversible, but the extent is unclear.

    On surgeries, the study noted that cross-sex surgery that includes hysterectomy and oophorectomy in transmen or orchiectomy in transwomen results in permanent sterility.

    One study showed that around 30% of male-to-female genital surgeries result in the inability to orgasm [1].

    Figures on female-to-male transitioners are less clear. However, a clinical follow-up study [2] of 38 transmen – 29 of whom had received phalloplasty, and 9 metoidioplasty – found that reported loss of orgasmic capacity was more marginally common than reported gain of orgasmic capacity.

    The negative intrapsychic and interpersonal consequences of anorgasmia (the inability to climax) is well-documented, and applies equally to transgender individuals [3].

    Male-to-female genital surgery (vaginoplasty) is associated with significant long-term complications: there is a 2% risk of fistula, 14% risk of stenosis (abnormal narrowing), 1% risk of necrosis (tissue death) and 4% risk of prolapse [1].

There is little evidence that medical transition decreases suicidality.

When it comes to gender dysphoric children, there is little evidence that medical transition decreases suicide rates. There is little evidence to assert that puberty blockers are necessary to prevent suicide [1].

After sex reassignment surgery, one study showed that adult transsexual clients were 4.9 times more likely to have made a suicide attempt and 19.1 times more likely to have died from suicide, after adjusting for prior psychiatric comorbidity [2]. Similarly, an Australian paper [3] notes that many patients have poor outcomes, which puts them at risk of suicide.

A prominent study [4] claiming that medical transition alleviated suicidality had to be corrected [5], to clarify that it proved “no advantage of surgery” in this regard.

A long-term Swedish study [6] finds that post-operative transgender people have “considerably higher risks” for suicidal behavior.

Similarly, a study in the European Journal of Endocrinology [7] demonstrates that suicide rates among transgender male-to-females were 51% higher than the general population.

There is evidence that all-cause mortality is higher among trans people than among the general population.

A Swedish study [1] found that sex-reassigned transsexual persons – both male and female – had approximately a three times higher risk of all-cause mortality than non-transsexuals. Elevated causes of mortality included cancer, cardiovascular disease, and violent crime:

This finding was backed up by a Dutch study [2], which stated:

This observational study showed an increased mortality risk in transgender people using hormone treatment, regardless of treatment type. This increased mortality risk did not decrease over time.

Studies on gender dysphoric young people often suffer from high rates of loss to follow-up – which could skew transition satisfaction rates.

In one study [1] of 77 pre-teen participants, 30% were lost to follow up by their teenage years: either they did not respond to the recruiting letter, or were not traceable. In another study [2], as many as 75% of participants were lost to follow up.

An excellent précis of this problem can be found in a 2018 paper [3], which gives further detail:

Smith et al. report that sex reassignment is effective, based on a study of 162 adults who had undergone SRS. They were able to obtain follow-up data from only 126 (78%) of subjects because a significant number were “untraceable” or had moved abroad.

De Cuypere et al. report that sex reassignment surgery is an effective treatment for transsexuals. Of 107 patients who had undergone SRS between 1986 and 2001, 30 (28%) could not be contacted and 15 (14%) refused to participate.

Johannson et al. reported good outcomes for SRS. Of 60 patients who had undergone SRS, 42 (70%) agreed to participate in the follow up research. Of the non-participants, 1 had died of complications of SRS, 8 could not be contacted and 9 refused to participate.

Salvador et al. reported that SRS has a positive effect on psychosocial functioning. Only 55 of the 69 patients (80%) could be contacted as 17 were lost to follow-up

Van de Grift et al. reported 94–96% of patients are satisfied with SRS and have good quality of life. A total of 546 patients with Gender Dysphoria who had applied for SRS at clinics in Amsterdam, Hamburg and Ghent were contacted to complete an online survey. Only 201 (37%) responded and completed the survey. 

A good example of how this phenomenon can affect satisfaction and regret statistics comes from a 2018 paper [4], which is often cited as proof of low regret rates. The loss to follow up rate in this paper is 36%. The authors also state:

In addition, in our population the average time to regret was 130 months, so it might be too early to examine regret rates in people who started with HT [hormonal treatment] in the past 10 years.

People with an incongruent gender identity are over four times more likely than the general population to suffer from mental health problems.

This finding, from an American campus survey [1], found that gender minority status was associated with “4.3 times higher odds of having at least 1 mental health problem.” Similarly, a Journal of Sex and Marital Therapy article [2] notes that “a large percentage of adolescents referred for gender dysphoria have a substantial co-occurring history of psychosocial and psychological vulnerability.”

In Lisa Littman’s seminal work [3] on rapid onset gender dysphoria, 62.5% of the young people whose parents were surveyed had at least one mental health or neurodevelopmental issue. 58.0% had a poor or extremely poor ability to handle negative emotions productively; 61.4% were overwhelmed by strong emotions and tried to avoid (or went to great lengths to avoid) experiencing them.

In a systematic review [4] of individuals diagnosed with gender dysphoria, 53.2% had at least one mental disorder in their lifetime. Such figures substantially exceed prevalence rates of comorbid psychopathology in the general population [5]: a further paper [6] studying hospital encounters found that the prevalence of mental disorder diagnoses was higher in transgender encounters (77%) than in the general population (37.8%).

A Swedish study [7] found that sex-reassigned persons had a higher risk of inpatient care for a psychiatric disorder (other than gender identity disorder) than the control population. Inpatient care for psychiatric disorders was also significantly more common among sex-reassigned persons than among controls, both before and after sex reassignment.
