Parts of the female sex organ

If fertilization does not occur, or for any other reason a blastocyst future embryo fails to implant within the endometrium, the built-up endometrial lining degenerates and is shed. The absence of a menstrual period in a sexually active woman may indicate that pregnancy has occurred. If fertilization takes place during ovulation, hormonal levels remain high, essential for the maintenance of the pregnancy. The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus. During the fetal stage, which lasts from 9 weeks after fertilization to birth, development continues as cells multiply, move, and change.

The vestibule is the area between the labia minora, and consists of the clitoris, urethral opening and the vaginal opening. The uterine lining is shed and expelled if no egg is implanted, and the bleeding is known as menstruation.
