Physiology of Menstruation

Menstruation is part of the process of preparing a woman's body for pregnancy each month. This cycle

Hormone signals the eggs in the ovaries to start developing. Shortly thereafter, an egg is released from the ovary and begins to move toward the fallopian tube to the uterus continues. If the egg is not fertilized by sperm during intercourse, the uterine lining will be separated from the uterine wall and begin to shed and will be removed through the vagina. Extravasation period known as the menstrual period, lasting for 3-7 days. If a woman becomes pregnant, her monthly menstruation stops.
