Progesterone Levels

Meaning

Progesterone levels refer to the circulating concentration of the steroid hormone progesterone, which is primarily synthesized by the corpus luteum in the ovary and, to a lesser extent, by the adrenal glands and testes. This hormone is essential for preparing the endometrium for potential pregnancy, maintaining gestation, and exerting a calming, anxiolytic effect on the central nervous system. Monitoring progesterone levels is critical for assessing ovulatory function, managing fertility treatments, and evaluating the hormonal status during the perimenopausal transition. Optimal levels are vital for reproductive health and emotional well-being.
