Estrogen Progesterone

Meaning

Estrogen and Progesterone are the two principal steroid hormones involved in regulating the female reproductive cycle, though both hormones also exert widespread systemic effects in all sexes. Estrogen, the primary sex hormone in women, is crucial for developing secondary sexual characteristics, maintaining bone density, and modulating cardiovascular and cognitive function. Progesterone, primarily known for preparing the endometrium for potential pregnancy, acts as a critical neurosteroid and possesses important anti-anxiety and anti-inflammatory properties throughout the body. Their precise, reciprocal balance is essential for cyclical health, mood stability, and long-term metabolic integrity.
