Reproductive Systems-Follicle

Postby kjnewman » Fri Nov 13, 2009 8:03 pm

I am having some trouble with an assignment question wondering if anyone would be able to help me? Here it is:

Explain what a follicle is, and why there are three stages of development for the ovary, but not for the testis.

If anyone can help me that would be greatly appreciated. Thanks so much and have a wonderful day! :)

Oogenesis is the process by which eggs are produced in the ovary, the process starts in the fetus when oogonia lining the germinal epithelium divide to form primary oocytes.the germinal epithelium also divides to form follicle cells. Which surround the primary oocytes forming primary follicles. So at birth , a baby girl will already have about a million primary follicles . the primary oocytes will have started to divide by meiosis, but the process stops at prophase I

FSH follicle stimulation hormone , and that hormone is secreted by the pituitary gland in the brain and its carried in the blood to the ovary, where it stimulates the development of one or more Graafian follicles

I hope that I helped but I don’t know what is the answer for the other part of your question ;)
