Chapter 52: The Reproductive Systems

Maturation of the Follicle and Oocyte

What is the function of the follicle? Each follicle is a single egg cell surrounded by several layers of follicle cells. An ovary consists of many follicles. The follicle cells protect and nourish the egg prior to its release into the oviducts during ovulation. The follicular tissue also release estrogens. The estrogens interact with other hormones produced in the brain to regulate the female reproductive cycle. Each follicle only produces a single egg and then breaks down.
