This shows the danger of not knowing enough. Testosterone is produced in
human male embryos from the eighth week, and is absolutely necessary for
the male sexual organs to develop. Fetal male rat and monkey brains develop
important behavioral characteristics due to their testosterone
secretion, and probably humans as well. It is thus not correct to state
that testosterone levels in male embryos and fetuses are not an
important difference from the female ones.
