The two ovaries are the major female sex organs, the counterpart of the male testes. The ovaries make the eggs, or oocytes, which are the female gametes, the female sex organs produce estrogen, the female sex hormone.
Estrogen causes female secondary sexual characteristics such as pubic hair, breast development, widening of the pelvis and deposition of body fat in hips and thighs. Eggs develop inside the ovary and are released upon ovulation into the Fallopian tube, which is lined with fingerlike projections that push the egg through the tube. During the egg’s travels through the Fallopian tube, fertilization can take place if sperm is present, and then the fertilized egg will continue to a muscular chamber called the uterus. The uterus, or womb, is where a fetus develops. It’s made of smooth muscle and is normally about the size and shape of a small pear turned upside down.
During pregnancy, it can stretch to about the size of a basketball to hold the developing baby. In the cervix is a tiny opening, about the size of a pinhead, called the external os. The vagina connects the uterus to the outside of the body, and its opening is covered by sets of folded skin called labia. The vagina receives the male’s penis during sexual intercourse and delivers the baby during childbirth.
The vagina is normally narrow, but can stretch during intercourse and childbirth. The secretions from these glands lubricate the labial folds during sexual excitation and intercourse.
