Estradiol E2 Anti Estrogen

Injections of estradiol are sometimes given to treat symptoms like these. They can also be used to compensate for ovary failure or similar conditions in women, and some forms of it can treat symptoms caused by prostate cancer in men. When given to women, it is necessary for them to use an effective form of birth control, due to the high risk of complications and birth defects that would exist in the event of a pregnancy.

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
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.
