I only know of about one or two examples, ever, given that almost no girls in the world are able to get t-blockers/estrogen/progesterone at an early enough age. If the girl is supported by her family, the medical community typically forces girls to wait until they're an "adult" meaning there's been some testosterone affect on them. If the girl isn't supported, she's typically working, meaning she needs use of her cock, also making there be some testosterone affect on them.
Only in the rare, rare, rare situation where a girl is extremely insistent at starting as early as possible, with unbelievably supportive parents are you going to get the biological conditions for a girl's body to form in the way that bio born women are, making them completely passable.
