The question wasn't whether they can get someone pregnant, the question was whether a penis was a definitive indication of maleness and the answer is, not exactly. Neither is the existence of female genitalia an obvious indication of XX chromosomes. Olympic runner Caster Semenya was identified as female at birth, has female genitalia and XY chromosomes and elevated testosterone production. The reality is is that there is no definitive biological definition of male and female. Males ares generally people born with penises and testicles and XY chromosomes who produce sperm but sometimes not exactly. Some women are born without wombs or have a normal looking vagina on the outside but testes instead of ovaries on the inside and this is due to the fact it's the same biological building blocks that our bodies use to create both male and female genitalia and reproductive systems.

The Gonads
Indifferent Stage
In the first stage of gonadal development, it is impossible to distinguish between the male and female gonad. Thus, it is known as the indifferent stage.
The gonads begin as genital ridges – a pair of longitudinal ridges derived from intermediate mesoderm and overlying epithelium. They initially do not contain any germ cells.
In the fourth week, germ cells begin to migrate from the endoderm lining of the yolk sac to the genital ridges, via the dorsal mesentary of the hindgut. They reach the genital ridges in the sixth week.
Simultaneously, the epithelium of the genital ridges proliferates and penetrates the intermediate mesoderm to form the primitive sex cords. The combination of germ cells and primitive sex cords forms the indifferent gonad – from which development into the testes or ovaries can occur.
Transgenderism and sexual development disorders aren't the same thing, Dipshit. I'm just explaining the ambiguity of biology for you Sknowflakes who feel uncomfortable living in a world that isn't black and white or binary.
Color dyes aren't chromosomes and sex hormones you ******* moron.
We don't need my thoughts on the matter, it's why I linked to the
science.
