Natural Steroid Hormones Fulvestrant Faslodex For Male Enhancement 129453-61-8

Hormones are chemical substances that are produced by glands in the body, which enter the bloodstream and cause effects in other tissues. For example, the hormone testosterone made in the testicles and is responsible for male characteristics such as deepening voice and increased body hair. The use of hormone therapy to treat cancer is based on the observation that receptors for specific hormones that are needed for cell growth are on the surface of some tumor cells. Hormone therapies work by stopping the production of a certain hormone, blocking hormone receptors, or substituting chemically similar agents for the active hormone, which cannot be used by the tumor cell. The different types of hormone therapies are categorized by their function and/or the type of hormone that is affected.

Many breast cancers have estrogen receptors, and the growth of these tumors can be stimulated by estrogen. Fulvestrant is an estrogen receptor downregulator, this means it binds to the estrogen receptor site in competition with estrogen in the body. Once it binds to the site it causes the receptors to break down, thereby preventing normal cellular response to estrogen.
