When do embryos develop into males?

Question

Quizplus · Accepted Answer

Male embryos develop when the testes form and begin to produce androgens, such as testosterone. This typically occurs around 6-8 weeks after fertilization. The presence of the Y chromosome is necessary for the development of testes and subsequent male features, but it is the production of androgens that drives the development of male genitalia and other physical characteristics. An absence of androgens during fetal development results in the development of female genitalia, regardless of whether the fetus has an XX or XY chromosome pair.
