Not exactly, more of a developmental thing. Human embryos are all created equal, and female. It's only during development that male embryos are masculinised by a rush of testosterone, that changes a whole host of things, it turns the organ that will become the cliteros into a penis and it changes the brain architecture.
In females Oestrogen is the ...[text shortened]... e are!
So, to sum up, male nipples are a reminder of our uterine trans-genderal experience.
Wrong. You are propagating an urban myth. In human embryos, both the müllerian duct system (female) and the wolffian duct system (male) develop at first.
The subsequent differences are the result of hormone levels that control the expression of gender-specific genetic information.

Originally posted by scottishinnzFair enough. Although that is the same as saying that the embryo would be female if it had no Y-chromosome -- rather circular.

Spherical reasoning--a circular argument inflated with--what?

Anyhoo, the really interesting bit is when you get XXYs (extremely effeminate men) or XYYs (super-ferocious males).

Originally posted by Bosse de NageThe said hormone influx is determined by the Y chromosome, ergo male or female -- it is still determined genetically. I could just as well argue that it becomes female due to the absence of testosterone.
