What is the Origin of Synthetic Gestagens?

The development of synthetic gestagens began in the mid-20th century with the search for orally active compounds that could effectively suppress ovulation and stabilize the endometrium. Their chemical origin lies in the modification of the progesterone molecule to enhance oral bioavailability and increase receptor affinity. This innovation was foundational to the creation of the first oral contraceptive pills.

What is the Mechanism of Synthetic Gestagens?

Synthetic gestagens exert their primary action by binding to the progesterone receptor in target tissues, such as the endometrium, hypothalamus, and pituitary gland, mimicking progesterone's effects. However, due to structural differences, many gestagens also possess residual androgenic, estrogenic, or glucocorticoid activity, which accounts for their distinct side effect profiles and clinical nuances compared to bioidentical progesterone. Their specific mechanism is dictated by their unique receptor binding profile.

Synthetic Gestagens

Meaning

Synthetic Gestagens are a class of pharmacologically active compounds, also known as progestins, that are chemically synthesized to mimic or modulate the biological effects of the naturally occurring steroid hormone, progesterone. These agents are utilized in various clinical applications, including hormonal contraception, menopausal hormone therapy, and the management of certain gynecological conditions. They differ structurally and pharmacodynamically from bioidentical progesterone, often exhibiting off-target effects on other steroid receptors.
