The surface of the ovary is covered by a layer of columnar cells which constitutes the germinal epithelium of Waldeyer. (Some sources consider it simple cuboidal.[1]

This epithelium gives to the ovary a dull gray color as compared with the shining smoothness of the peritoneum; and the transition between the squamous epithelium of the peritoneum and the columnar cells which cover the ovary is usually marked by a line around the anterior border of the ovary.

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.

In mammals, oogenesis occurs in the ovarian follicle 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.
