Just FYI: hardly any males claiming to be women today get castrated.
The whole reason the trans lobby started focusing exclusively on suppressing testosterone through use of T-blockers and estrogen - and claiming that the male advantage in sports could be eliminated if "transwomen" lower their T to 10 or 5 nmol/L for a year or two - is because most males who "transition" nowadays still have their balls and dicks and want to keep them.
This is particularly true of those who decide to "transition" in adolescence and adulthood, after they've had the chance to experience male sex drive, male arousal and male orgasm.
Nowadays, the only males who identify as the opposite sex who routinely are getting their balls removed and penises reconfigured for the purpose of "gender affirmation" are the teenagers who were "transitioned" in childhood prior to puberty by their parents, gender therapists and doctors - and who were put on "puberty blockers" early enough to prevent them from maturing enough to experience normal male libido, erections and male sexual pleasure. Such as poor Jazz Jennings and Trinity Neal, both of whom were prevented from going through puberty and ended up being castrated and having their penises removed and reconfigured before they reached the age of majority and legal consent.
Most males who have experienced male libido, arousal and sexual pleasure don't ever want to give that up even when they claim they "feel like" and "identify as" women and demand to be allowed to compete in women's sports and use women's locker rooms, showers and loos.
It's because nearly all "transwomen" keep their balls and dicks that there have already been several cases in the US and UK where female prison inmates have been raped or impregnated by "transwomen" convicts after the "transwomen" have been transferred from men's prisons to women's correctional facilities.
When males seek and get "gender confirmation" surgeries nowadays, the genitals are rarely involved. The most common supposedly 'life saving" surgeries and procedures that males get for purposes of "gender transition" are facial feminization surgeries, facial hair removal procedures, tracheal shaves, hairline lowering, body contouring, butt lifts and butt augmentation, fillers and fat injections, and surgeries to implant rounded silicone sacs into the chest wall to give the appearance of fully-developed female breasts.
