Long term use of anabolic-androgenic steroids (synthetic testosterone) is associated with brain ageing and a decline in cognitive processing
One study suggests that long-term use of anabolic-androgenic steroids (AAS) may cause accelerated brain ageing in certain regions, which could lead to cognitive abnormalities.
A 2021 study by Bjørnebekk et al1. aimed to investigate the effects of long-term anabolic-androgenic steroid (AAS) use on brain ageing. The study included 229 male participants, 130 of whom were long-term AAS users and 99 were non-users. The participants underwent T1-weighted magnetic resonance imaging (MRI) scans to assess brain ageing. The results showed that long-term AAS use is associated with accentuated brain ageing in certain regions, particularly the frontal and cingulate regions. The study highlights the need for further research on the long-term effects of AAS use on brain health and cognition.

60% of males and 70% of females attending the world’s largest gender clinic (GIDS) are same-sex attracted
In the 2015 statistics from GIDS, approximately 60% of the youth seen there who were biological males and 70% who were biological females reported attraction to the same sex or to both sexes1.
The 2015 Gender Identity Development Service (GIDS) statistics revealed a notably high rate of same-sex attraction among the youth seen at their clinic. Over half of the biological females reported same-sex attraction, about 20% were attracted to both sexes, and a quarter to the opposite sex, with the remaining identifying as asexual. Among biological males, approximately 30% reported same-sex attraction, another 30% to both sexes, 30% to the opposite sex, with the last 10% identifying as asexual or reporting no sexual attraction.

It is not true that 1.7% of the population is ‘born between the sexes’. The proportion of people with DSDs (‘intersex’ conditions) is 0.018%
Conditions in which chromosomal sex is inconsistent with phenotypic sex, or in which the phenotype is not classifiable as either male or female, occur in 0.018% of the population1.
The claim that 1.7% of the population is ‘intersex’2 includes conditions which most clinicians do not recognize as intersex, and is often wrongly used to back up the ideological assertion that ‘sex is a spectrum’, or that biological sex is not dimorphic.
The philosopher Kathleen Stock points out that she would be considered as “intersex” under Fausto-Sterling’s “preposterously over-demanding conditions on sex category membership”, as she lost an ovary in early adulthood3, which would count as “intersex” according to Fausto-Sterling.

There are 2 sexes: male and female. Biological sex is not a spectrum
According to an Endocrine Society Scientific Statement1,
Sex is dichotomous, with sex determination in the fertilized zygote stemming from unequal expression of sex chromosomal genes.
Sex differences in baseline physiology and associated mechanisms form the foundation for understanding sex differences in diseases pathology, treatments, and outcomes.
The erroneous claim that biological sex is a spectrum, or non-dichotomous, is often used to justify the ideological assertion that all humans are ‘assigned sex at birth’. In fact, biological sex is encoded in every cell of the body2.

In one study of detransitioners, males were three times more likely than females to have transitioned for erotic reasons
In a study1 of 100 detransitioners, 38.7% of males identified with the comment “I had erotic reasons for wanting to transition”.
The figure for females was a third of this, at 13%.

There is evidence that up to a quarter of transgender genital surgeries result in incontinence
A systematic literature review1 found that 21% of male-to-female patients and 25% of female-to-male patients suffered from incontinence as a result of transgender genital surgery.
One recent study2 estimates the number of post-operative transsexuals suffering stress incontinence to be 23%. This study was not a literature review, and almost all of the participants were male-to-female.

Around 1 in 5 vaginoplasty surgeries lead to corrective surgery
A systematic review1 of neo-vagina surgeries found a re-operation rate of 21.7% for non-esthetic reasons.
A Brazilian paper2 found a somewhat lower, but similar, reoperation rate of 16.8%.

Vaginoplasty can result in fistula, stenosis, necrosis, prolapse and even death
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 prolapse1.
One systematic review2 found an overall complication rate of 32.5%.
A Dutch study3 of 55 (out of an original 70) adolescents treated with puberty blockers, cross sex hormones, and genital surgery, showed that among 22 male-to-female patients who underwent vaginoplasty, one adolescent died as a result of necrotizing fasciitis after the surgery.

Feminizing hormones reduce sexual function in males
Feminizing hormonal treatments lead to a lessening drive, erectile dysfunction, and shrinking of testes and penis1, significantly compromising sexual function.
A Belgian doctoral thesis study2 found that 69.7% of transwomen reported a decrease in sexual desire — while the opposite effect is found in transmen.

Genital surgeries tend to reduce the capacity for orgasm in males, and may do so in females
One study showed that around 30% of male-to-female genital surgeries result in the inability to orgasm1.
Figures on female-to-male transitioners are less clear. However, a clinical follow-up study2 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 individuals3.

In one survey, 50% of transwomen who tucked were concerned about negative health effects
A survey1 of transwomen who tucked (the process of reducing the visible male crotch bulge) reported that half were concerned about the health effects of tucking.
Their reported symptoms included itching (28%), rash (21%), testicular pain (17%), penile pain (14%), and skin infections (12%).
In addition, patients may be reluctant to seek medical care for testicular complaints and when they do, it may be already late to salvage the testis.2

One case study suggests that tucking can cause testicular torsion
A case study1 found that one transwoman had testicular torsion as a result of tucking.
Testicular torsion – the rotation of the testes and subsequent arterial constriction – can present as severe acute unilateral scrotal pain, nausea, and vomiting. If permanent ischemic damage results, delay in treatment may be associated with decreased fertility, or may necessitate orchiectomy2.

While long-term study is lacking, one case study suggests that tucking can affect fertility
In a case study1 of one transwoman, tucking resulted in oligospermia – an abnormally low sperm count – affecting fertility. Elevation of the testes because of tucking may contribute to heat stress and consequent impairment of spermatogenesis.
After cessation of tucking and the provision of a new sperm sample, the sperm count in the patient was improved, and the semen had increased opacification.
A further study2 found that tucking could create a suboptimal environment for spermatogenesis.

Medical transition puts both males and females at risk of infertility
A wide-ranging study1 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.

The chances of developing osteoporosis and cardiovascular problems increase with feminizing hormones
A 2012 paper1 found that a quarter of the male-to-female transsexuals it studied had osteoporosis at the lumbar spine and radius.
In the same study, 6% of male-to-female transsexuals experienced a thromboembolic event (a blood clot causing obstruction), and another 6% experienced other cardiovascular problems. These effects were observed after only 11.3 years of hormone treatment on average.
A further study2 found that long-term bone mineral density decreases in transwomen who take cross-sex hormones in the long term.

One study showed that, without social transition, nearly two-thirds of pre-teen gender-dysphoric males grow up to be gay or bisexual
A University of Toronto study1 found that 63.6% of boys with early onset gender dysphoria, who received ‘watchful waiting’ treatment and no pre-pubertal social transition, grew up to be gay or bisexual.
Only 12% of the study participants continued to identify as transfeminine.

The profile of people seeking transition has shifted drastically, from overwhelmingly middle-aged males to predominantly adolescent females
A 2017 paper1 notes that “in adolescents, there has been a recent inversion in the sex ratio from one favouring birth-assigned males to one favouring birth-assigned females.” By contrast, over 90% of transsexual adults in the 1960s were male2.
In fact, there was hardly any scientific literature before 2012 on girls ages 11 to 21 ever having developed gender dysphoria at all. Yet of the young people described in Lisa Littman’s 2018 seminal paper on young people3, 82.8% were female.
The data for the UK’s Gender Identity Development Service4 show that 138 children were referred in 2011, and most of those children were boys. By 2021, however, a complete sex ratio reversal had occurred, and the clinic saw 2383 children that year, with almost 70% being female.
A 2017 article by Lisa Marchiano5 collated data from different clinics around the world and found international evidence for this shift in distribution.
