@sleepybisexual lol.
It works by, for an AMAB, removing the scrotum and tedticles, leaving the penis as is, then crafting a shorter vulva with or without, according to the preference of the person getting it, a standard vaginal canal where the perineum would otherwise be.
So, yes. It would remove the testes, ending major testosterone production (your adrenal gland would still make some--usually enough to meet your needs otherwise).
