Ovarian follicles are the basic unit of female reproductive biology, they are roughly spherical aggregations of cells found in the ovary. They contain a single oocyte (aka ovum or egg).

At one part of the mature follicle the cells of the membrana granulosa are collected into a mass which projects into the cavity of the follicle. This is termed the discus proligerus.

- Sexual reproduction.
The human female reproductive system contains two main parts: the vagina and uterus, which act as the receptacle for the male's sperm, and the ovaries, which produce the female's ova.

The reproductive system is the ensembles and interactions of organs and/or substances within an organism that strictly pertain to reproduction. As an example, this would include in the case of female mammals, the hormone estrogen, ova, and the uterus and the vagina, and the breasts.

The medulla of ovary (or Zona vasculosa of Waldeyer) is a highly vascular stroma in the center of the ovary.
This stroma forms the tissue of the hilum by which the ovary is attached, and through which the bloodvessels enter: it does not contain any ovarian follicles.

corpus albicans (Latin for "white body" ) is the regressed form of the corpus luteum. As the corpus luteum is being broken down by macrophages, fibroblasts lay down type I collagen, forming the corpus albicans. This process is called "luteolysis".
