Ovarian follicle
Ovarian Follicle
The Ovarian Follicle (/oʊˈvɛəriən ˈfɒlɪkəl/) is a crucial component of the female reproductive system.
Etymology
The term "Ovarian Follicle" is derived from the Latin words "ovarium" meaning egg, and "folliculus" meaning small bag.
Definition
An Ovarian Follicle is a fluid-filled sac located within the ovary that contains an immature oocyte (egg cell). Each month, during the menstrual cycle, a few ovarian follicles are activated, and usually only one matures to release an oocyte during ovulation.
Function
The primary function of the Ovarian Follicle is to nurture and release the oocyte. The follicle also produces estrogen, a hormone that plays a vital role in the menstrual cycle and pregnancy.
