(10) Which hormones control the female reproductive cycle? Describe the function of each.
 * GNRH: stimulates anterior pituitary to secrete the gonadotropic hormones. GNRH stimulates hair growth, and controls production of testosterone by the intersitial cells.
 * Testosterone: triggers muscle development, develops male reproductive organs and brings about other features such as beards and adams apple.
 * The ovaries:produce eggs and female sex hormones
 * oviducts: where the egg is put into the ciliary movement
 * uterus: houses developing fetus
 * cervix: contains opening to uterus
 * vagina: receives penis during intercourse and is birth canal and exit for menstrual cycle
 * FSH: Is made in the brain and is in the pirtuitary glands. Respoonsible for the egg to start developing.
 * Estrogen: is made in the ovaries. As the egg matures in the ovaries estrogen is being made by the egg in the ovary.
 * LH: is made in the brain. Estrogen tells the brain to release LH and LH tells the body to ovulate.
 * Progesterone: prepares body for conception.
