Question: hormones?? what four hormones are important in controlling menstrual cycle and preganny and breast feeding and what are the functions of each??

Answer: Estrogens Function : * development of breasts * further development of the uterus and vagina * broadening of the pelvis * growth of pubic and axillary hair * increase in adipose (fat) tissue # participate in the monthly preparation of the body for a possible pregnancy # participate in pregnancy if it occurs Progesterone: Progesterone is also a steroid. It has many effects in the body, some having nothing to do with sex and reproduction. Here we shall focus on the role of progesterone in the menstrual cycle and pregnancy estrogen : About every 28 days, some blood and other products of the disintegration of the inner lining of the uterus (the endometrium) are discharged from the uterus, a process called menstruation. During this time a new follicle begins to develop in one of the ovaries. After menstruation ceases, the follicle continues to develop, secreting an increasing amount of estrogen as it does so. TSH, FSH, and LH HCG behaves much like FSH and LH with one crucial exception: it is NOT inhibited by a rising level of progesterone. Thus HCG prevents the deterioration of the corpus luteum at the end of the fourth week and enables pregnancy to continue beyond the end of the normal menstrual cycle. I hope that helps you :)
