What are the active ingredients in the combined oral contraceptive pill and their mechanisms of action?
The active ingredients of the combined oral contraceptive pill are estrogen and progesterone. These pills are taken to prevent ovulation to prevent unwanted pregnancies. There is synergism between estrogen and progesterone where estrogen leads to progesterone receptors being upregulated so that they are more sensitive to progesterone. The combined oral contraceptive pill is highly effective. Its effect on preventing ovulation is the greatest. In addition to these effect, it can prevent unwanted pregnancies by thickening the cervical mucus, reducing the transport of the egg and the sperm in the Fallopian tubes, and changing the endometrium so that implantation is less likely to occur.

Can sheep come into heat after being bred?
Normally when sheep are pregnant they will not come into heat. If they have come into heat after being bred it is a sign that they did not catch or have aborted the fetus. The reason why they do not come into heat is because progesterone levels have increased, while estrogen and testosterone hormone levels decrease. After fertilization of the egg, a corpus luteum is formed, which then continues to produce progesterone and prevent further estrous cycle.
What do estrogen and progetrogen do?
Progesterone counteracts the dangerous effects of excess estrogen in the body. I'm not 100% on what estrogen does, but I know birth control works by tricking the body into thinking it's already pregnant so you stop ovulating. That might be where the estrogen comes into play.

What gland seretes estrogen?
Estrogen's are produced primarily by developing follicles in the ovaries, the corpus luteum, and the placenta. Luteinizing hormone (LH) stimulates the production of estrogen in the ovaries. Some estrogen's are also produced in smaller amounts by other tissues such as the liver, adrenal glands, and the breasts. These secondary sources of estrogens are especially important in postmenopausal women. Fat cells also produce estrogen,[6] potentially being the reason why underweight or overweight are risk factors for infertility.

Which hormones affect acne in woman?
Androgens -- testosterone in particular. Your estrogen levels drop around the time before your period and you may notice that's when you get pimples. As estrogen drops, testosterone naturally rises --lucky you, you get pimples! If you are a woman in your mid life (30's ) the best way to make sure your body is in balance is to request a hormone profile from your obgyn. This is a simple blood test drawn at certain times of the month (your doctor and you can figure that out) and then reveals what levels your estrogen, testosterone, progesterone and other hormones (thyroid) etc... are and if they are correct. Not only can an imbalance cause adult acne, but also can cause depression (too little estrogen affects seratonin --- too much progesterone can also cause depression symptoms) -- so, it's really important to know your levels so you're not being incorrectly treated for something that could be another.
