Document Summary
If the fetus is exposed to dht during this critical period of development, it will develop male external genitalia: depends upon the amount of exposure and the timing of it. In contrast, the male is still in the process of producing spermatogonia in large numbers: puberty. In the case of the female, because of the reproductive cycle, at the beginning of the ovarian cycle, several oocytes will undergo primary meiotic division and start to mature into: secondary oocyte, controlled by hormones. If it is, then it will release the polar body which will degenerate: end up with a zygote, so, for every single primary oocyte, you end up with only one single ovum. In here it triggers the release of lh and. Fsh into the bloodstream: they then travel down to the. In the case of testosterone: would be fairly constant over time. If the testosterone levels get really high, then it will continue to reinforce the negative feedback.
