menstrual cycle
|
The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone
. Estrogen and progesterone stimulate the uterus and breasts to prepare for possible fertilization. The cycle has three phases: menstrual phase (before release of the egg), proliferative phase (egg release), and secretory (after egg release) Bleeding occurs after estrogen and progesterone levels decrease at the end of the previous cycle. This decrease causes the top layers of thickened lining of the uterus (endometrium) to break down and be shed. The proliferative phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation) This phase begins after ovulation. It lasts about 14 days (unless fertilization occurs) and ends just before a menstrual period. In this phase, the ruptured follicle closes after releasing the egg and forms a structure called a corpus luteum, which produces increasing quantities of progesterone . The corpus luteum prepares the uterus in case fertilization occurs. The progesterone produced by the corpus luteum causes the endometrium to thicken, filling with fluids and nutrients to nourish a potential fetus. Progesterone causes the mucus in the cervix to thicken, so that sperm or bacteria are less likely to enter the uterus |
