In the female there are two ovoid ovaries attached to the dorsal body wall just below the kidney. Eggs or ova develop inside the ovaries of the mature female. It is thought that about 70000 potential cells are already present at birth; only about 500 will ever become mature within the two ovaries and they are released from puberty to menopause. Usually only one egg is released every month. The ovaries take turns to release the egg.

The egg is spherical with a diameter of about 120 mm. It has a large nucleus containing one haploid set of chromosomes. Abundant cytoplasm is present and may contain a small amount of yolk. The egg has a plasma membrane which is in turn surrounded by the vitelline membrane.

The ovary releases the ripe ova (eggs) into the oviduct at certain times. There are two oviducts. Each oviduct, or fallopian tube, is a narrow muscular tube. It leads from the ovary to the uterus. It has a funnel-like opening lying close to the ovary. This makes it easier for the egg to inter the oviduct.

The uterus is the name for the womb. It is where the baby or foetus develops during pregnancy. It is pear shaped and about 7.5 cm long. The uterus has muscular walls. It's inner lining is called endometrium and it is soft and smooth. Part of this lining is sloughed off during monthly menstruation.
