ikadub [295]

The ovary is the part of the female reproductive system that produces ova.

The ovary is an organ located in the female reproductive system that produces female reproductive cells or ova. The ovary is often paired and are firm, smooth and about the size of an almond. The ovaries are held by a membrane next to the uterus on both side of the lower abdomen. When an ovum is produced, it moves into the uterus through the fallopian tube, where it may be fertilized by a sperm. The ovary also secretes various hormones such as estrogen and progesterone that perform major roles in the menstrual cycle and fertility.
