Description:
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.
Despite a common belief to the contrary, estrogens are important for male reproductive health and development as well. Estradiol is produced by a certain type of cell in the testes, and evidence suggests that it may be responsible for preventing the spontaneous death of sperm cells. Elevated levels can have negative effects, including a lowered sperm count. Males who have genetic conditions involving the sex chromosomes, such as Klinefelters Syndrome, often have higher-than-normal levels. While it is primarily a sex hormone, estradiol also has complex interactions with the liver, governing the production of certain proteins, including those responsible for blood clotting.
Functiona:
As a sex hormone, E2 has several different functions in womens 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.1. All inquiries will be replied within 12 hours.
