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
