See why the ovary − often reduced to its reproductive role − menopause, age and estrogen affect a woman’s health throughout her body and lifetime.

This important study reports that two distinct waves of ovarian follicles contribute to oocyte production in mice. The paper provides large amounts of data that will benefit future studies, although ...

This stimulates multiple ovarian follicles to begin maturing. As the levels of FSH begin to drop, usually only one follicle continues to mature. This follicle releases estrogen, and estrogen ...

Primordial follicles, formed in the womb, make up the ovarian reserve, which is finite and nonrenewable. The ovarian reserve naturally declines across a female’s reproductive lifespan.

A mouse ovary treated with a high dose of anti-Mullerian hormone (AMH)—a hormone naturally produced by follicles in the ovary—shows more small, dormant follicles and fewer larger ones.

An artificial ovary may soon be possible, according to researchers who have engineered an ovarian “scaffold” on which early-stage cells can develop into functional follicles.
