description:

1. this product is white or milky white odorless crystalline powder; in dioxane, dissolved in acetone,

slightly soluble in ethanol, insoluble in water.estradiol is a sex hormone that is present in both males and

females, and is the most important form of estrogen in humans. in women, it plays a key role in the

development and functioning of the reproductive system, as well as in the growth of certain bones. it also

governs the distribution of body fat in women and is the main hormone responsible for the fact that women

are shorter than men, on average. both the ovaries and the adrenal glands produce it.

2. the menstrual cycle in women involves predictable variations in the levels of several hormones, with

estradiol being one of them. it is involved in the ovulation process and prepares the inner lining of the

uterus for implantation, should the egg be fertilized. certain tests done on baboons and other primates

have indicated that his hormone also plays a continual role in maintaining a pregnancy, helping it to last

for the full gestation period.

3. as a sex hormone, it also triggers many of the developments of the reproductive system that begin in

puberty. it is present throughout the reproductive years, and declines during and after menopause. this

decline is precisely what causes many of the symptoms of menopause, such as hot flashes and night

sweats, vaginal dryness, and the loss of bone mass that may lead to osteoporosis.

4. estradiol for functional uterine bleeding, primary amenorrhea, menopausal syndrome, prostate cancer.

can promote and regulate the female sexual organs and sexual characteristics of the normal

development. can promote the development of mammary duct proliferation, but in a larger dose, can

inhibit the release of anterior pituitary prolactin, while reducing milk secretion. can also be used to return

milk. but may have nausea, vomiting and endometrial hyperplasia and bleeding. liver and kidney

dysfunction with caution. avoid for the breast, vulva and vaginal mucosa.

applications:

1. this medication is a female hormone (estrogen). it is used by women to help reduce symptoms of

menopause (such as hot flashes, vaginal dryness). these symptoms are caused by the body making less

estrogen. if you are using this medication to treat symptoms only in and around the vagina, products

applied directly inside the vagina should be considered before medications that are taken by mouth,

absorbed through the skin, or injected. this medication may also be used by women who are not able to

produce enough estrogen (for example, due to hypogonadism, primary ovarian failure).

2. as a sex hormone, e2 has several different functions in women’s fertility. first, it helps to build and

protect the lining of the fallopian tubes, vagina, and uterus. this role is critical to get the embryo to attach

to the uterine wall. many women who experience fertility problems have low levels of estradiol. second, e2

maintains the oocytes, or egg cells, in the ovary. healthy oocytes lead to healthy embryos. only the best

oocyte is selected at each ovulation period to be released and possibly

3. as a tissue builder, e2 seems to help protect women from heart disease by raising the levels of hdl,

the “good” cholesterol in the body. when hormone levels drop in postmenopausal women, their risk of

heart disease increases. e2 also helps protect bone density in both men and women by participating in a

messaging system that suppresses an overly rapid growth of immune cells in the bone. if more immune

cells are allowed to grow, they can block calcium absorption in the bone. this is why men with lower levels

of this hormone in their system have been found to be more susceptible to hip fractures.
