Don’t believe them. They have multi negative effects on both males and females.
And in that little boys case why would you give puberty blockers to a 7 yr old child and she wanted to start at around 5.
Hormone blockers to cross-sex hormones stunt genital growth in males & may permanently damage sexual function When young dysphoric males are given hormone blockers at the onset of puberty, it stops genital growth (“micro penis”) and this becomes permanent if the youth goes on to cross-sex hormones. There isn’t any evidence available as to whether all of these effects on sexual function in a pubertal male are “fully reversible,” if the youth stops blockers and resumes a “normal puberty.” If the youth does not want to go through life with an 11-year-old’s penis, the youth will now have to have a portion of their colon or peritoneal lining around the stomach extracted, along with skin from the abdomen, in order to make a “neovagina” (rather than inverting a penis, which is how it is done on adults).
There is a confirmed case of this happening to a trans teen television celebrity who has a reality show (we view this as exploitation). The teen mentioned having little sexual desire, never having had an orgasm at age 16, has a penis the size of an 11-year-old’s, and has had to have an extra graft and painful surgery in order to make a “neovagina.”
Here is another example of this situation, as described by a concerned parent on a transgender social media forum.
