Everything You'll Have Covered

Describe what happens to the eggs in the female body each month from puberty until menopause.

~ Each month, an egg matures in one of the ovaries and is released into a fallopian tube. The eggs mature in follicles in the ovaries. The follicles are controlled by a follicle-stimulating hormone (FSH), which is secreted by the pituitary gland. FSH stimulates an egg so that it can mature in the follicles before it is released into one of the fallopian tubes. If the egg meets a sperm and is fertilized, the egg attaches itself to the thickened endometrium and develops there. If the egg is not fertilized, it is released from the body along with the endometrium of the uterus.

What is the corpus luteum?

~ The corpus luteum is the fat storing structure formed from the ruptured follicle. It secretes estrogen and progesterone. Progesterone triggers the endometrium to thicken in preparation for a fertilized egg.

What is the menstrual cycle?

~ The menstrual cycle is the series of events beginning with the maturation of an egg and ending with the release of the egg and endometrium.
