Progesterone is a steroid hormone primarily produced by the corpus luteum in the ovary during the luteal phase of the menstrual cycle and by the placenta during pregnancy. It plays essential roles in menstrual cycle regulation, pregnancy maintenance, and has various metabolic effects throughout the body. Progesterone is synthesized from cholesterol and serves as a precursor to other steroid hormones. In reproductive-age females, it prepares the endometrium for implantation and maintains early pregnancy. In both sexes, progesterone influences neurological function, bone metabolism, and cardiovascular health.
Progesterone is a hormone that helps regulate the menstrual cycle and maintain pregnancy. Your levels depend on many factors including your sex, age, and where you are in your menstrual cycle.
When elevated: Elevated progesterone outside of luteal phase or pregnancy may indicate ovarian cysts, adrenal disorders, or exogenous hormone use. During pregnancy, abnormally high levels may suggest molar pregnancy or multiple gestation. When low: Low progesterone during the luteal phase may indicate anovulation, luteal phase defect, or impending miscarriage in early pregnancy. In men, very low levels are normal but extremely low levels may affect mood and cognitive function.
Progesterone influences recovery, muscle protein synthesis, and bone health in female athletes. Tracking progesterone across cycle phases helps contextualize performance fluctuations, training tolerance, and injury risk, particularly during the luteal phase when some athletes experience changes in strength, endurance, or mood.
