Ovaries (singular: Ovary) are organs found in female organisms. Ovaries are part of the reproductive system needed to reproduce sexually.
Most vertebrate animals have two ovaries. Birds usually have only one working ovary; snakes have one ovary in front of the other. The ovaries are similar to testicles in male organisms.
Anatomy[change]
Ovaries are shaped like ovals. They are around 3 cm by 1.5 cm by 1.5 cm. The ovaries are found in the side walls of the pelvis.
Each ovary is attached to a fallopian tube, each of which is attached to the uterus. Usually each ovary takes turns releasing eggs every month.
Uses[change]
Ovaries have two purposes. They produce female sex hormones that help puberty take place. Ovaries also produce ova (also called "egg cells"), which are the female reproductive cells.
In menstruation[change]
During menstruation, an ovum is released from the ovary and enters one of the fallopian tubes. There, the ovum can be fertilised. Ovaries have a certain number of eggs in them; when eggs stop being released, this is the start of the menopause. During this time, female hormones stop being produced.
