Is estrogen or progesterone more important in getting pregnant?
progesterone in getting pregnant and estrogen in staying pregnant---so you need both good luck Joymaker RN
Because the ovaries do not make just estrogen. The ovaries actually make androgens and enzymes, and the hormones needed are created in the blood by the precursors created by the ovaries. So you end up with estradiol (most potent human form of estrogen), progesterone, and still have some of the intermediary androgens used to make the estrogen and progesterone.
What you are calling a hysterectomy here might actually be a "complete hysterectomy," or an "oophorosalpingohysterectomy." That is when not only the uterus is removed, but the ovaries and Fallopian tubes are too. That is what a veterinarian does when they spay an animal. They remove everything. So when the ovaries are removed, women lose not only estrogen, but the other hormones as well. In addition, they would likely need more estrogen and doctors are too scared to give enough estrogen to help them. They often don't realize that surgical removal requires more estrogen than natural menopause does.
Then you run into issues with bio-availability and hormone ratios. Human females have 3 main estrogens circulating - 17 beta estradiol (e2), estrone (e1), and estriol (e3). Hormone replacement replaces only one since presumably, the body can convert between them as needed. Whether women in this age bracket who have surgical menopause can convert between them is another issue. While compounding pharmacies can make you a ratio similar to what is found in other women, the FDA doesn't approve the addition of estriol, nor do they ban it at this point either. Estriol seems to do well enough on its own at relieving hot flashes without causing breast symptoms. But if given in high dosages, estriol can break down into an estrogen compound that may be implicated in certain cancers. Nobody has submitted estriol or a combination drug to the FDA for evaluation, so the medical profession cannot legally make any beneficial claims for it.

What are the effects of being on synthroid and estrogen therapy?
Synthroid reverses symptoms of hypothyroidism like weight gain, fatigue, dry skin, depression - caused by the under active thyroid gland.
Estrogen replaces hormones lost due to menopause or oophorectomy - causing mood swings, hot flashes and general discomfort.
Why anti estrogen drugs are given in post menupause mastectomy?
If it's done,
it's done because you know or assume that
the tumor cells respond to estrogen
as a growth factor.
Pre-Ovulation (Day 2 -14)
The menstrual bleeding usually lasts a few days. From Day 2 on, the body is already starting to prepare itself for the next cycle. Under the influence of Follicle Stimulating Hormone (FSH) and LH (Luteinizing Hormone) from the pituitary gland, the ovarian follicle starts to manufacture and secrete estrogen. Estrogen causes the uterine lining to grow. About 15 to 20 eggs start to mature in each ovary during this period. Each egg is encased and protected in its own follicle. The follicles also produce estrogen, the hormone necessary for ovulation to eventually occur. The level of estrogen slowly rises during this period as the uterus lining thickens and starts its preparation to receive the egg if ovulation occurs. A race progresses for one follicle to become the largest. Eventually, ovulation occurs when one ovary releases an egg from the most dominant follicle.
Ovulation (Day 14-15)
Although it averages about two weeks, this race to release an egg can take anywhere from about 8 days to a month or longer to complete. The key factor that determines how long it will take before you ovulate is how soon your body reaches its estrogen threshold. The high levels of estrogen will trigger an abrupt surge of Luteinizing Hormone (LH). It's this LH surge that causes the egg to literally burst through the ovarian wall, usually within a day or so of the occurrence that we called ovulation. After ovulation, the egg tumbles out into the pelvic cavity, where it is quickly transported into the fallopian tubes. The remainder of the ruptured follicle (called the corpus luteum) recedes back to the ovary and begins an important task of secreting progesterone. Why is progesterone so important? It causes an increase in blood vessels to the uterine lining in order to provide nutrients for the fetus in case fertilization occurs. It also inhibits other eggs from developing, and causes the Basal Body Temperature (BBT) to rise about half a degree.
Is there such thing as a surgery that removes estrogen from your body?
No. If you don't want estrogen in your body you would need to take testosterone pills. what just happens is just that you will look very much like a men
Estrogen functions as the primary female sex hormone.
While oestrogens are present in both men and women, they are usually present at significantly higher levels in women of reproductive age. They promote the development of female secondary sexual characteristics, such as breasts, and are also involved in the thickening of the endometrium and other aspects of regulating the menstrual cycle. In males, oestrogen regulates certain functions of thereproductive system important to the maturation of sperm[9][10][11] and may be necessary for a healthy libido.[12][13] Furthermore, there are several other structural changes induced by oestrogen in addition to other functions.
- Structural
- promote formation of female secondary sex characteristics
- accelerate metabolism
- reduce muscle mass
- increase fat stores
- stimulate endometrial growth
- increase uterine growth
- increase vaginal lubrication
- thicken the vaginal wall
- maintenance of vessel and skin
- reduce bone resorption, increase bone formation
- morphic change (endomorphic -> mesomorphic -> ectomorphic)
- protein synthesis
- increase hepatic production of binding proteins
- coagulation
- increase circulating level of factors 2, 7, 9, 10, plasminogen
- decrease antithrombin III
- increase platelet adhesiveness
- Lipid
- increase HDL, triglyceride
- decrease LDL, fat deposition
- Fluid balance
- salt (sodium) and water retention
- increase cortisol, SHBG
- Gastrointestinal tract
- reduce bowel motility
- increase cholesterol in bile
- Melanin
- increase pheomelanin, reduce eumelanin
- Cancer
- support hormone-sensitive breast cancers
- Lung function
- promotes lung function by supporting alveoli (in rodents but probably in humans).
Is it okay to cut estrogen patches?
My OB/GYN told me that it was fine to cut the patch to get half of the dose and it seems to be working well, since on the full .025 I had gained 5 lbs in just 2 weeks. Hot flashes are still being minimized with the half patch so far.
No it doesn't. Think about this a LOT of men sit around drinking this stuff watching football. If it had estrogen wouldn't they be watching STYLE instead?
