Ethisterone

Description:

Ethisterone, also known as 17α-ethynyltestosterone, is a synthetic steroid hormone that belongs to the class of progestins. It is characterized by its structural similarity to testosterone, featuring an ethynyl group at the 17α position, which enhances its oral bioavailability and potency. Ethisterone is primarily used in hormonal therapies, including contraceptives and treatments for menstrual disorders. Its mechanism of action involves binding to progesterone receptors, thereby influencing the menstrual cycle and maintaining pregnancy. The substance is typically administered in oral form and is known for its ability to regulate ovulation and menstrual cycles. Ethisterone exhibits a relatively long half-life, allowing for sustained therapeutic effects. Additionally, it may have androgenic properties, which can lead to side effects such as weight gain, mood changes, and alterations in libido. As with other synthetic hormones, careful monitoring is essential to mitigate potential adverse effects and ensure effective treatment outcomes.
