Homework Help: Biology

Posted by Stuck on Sunday, March 21, 2010 at 5:20pm.

During the follicular stage of the menstrual cycle, both FSH and estrogen are high, but aren't estrogen and FSH on a negative feedback loop?

Is it just because FSH is not directly involved in the increase of estrogen (it is the follicle that increases estrogen) that both of them remain high?
