Ovarian Axis

Meaning

The Ovarian Axis is a simplified clinical term for the Hypothalamic-Pituitary-Ovarian (HPO) axis, which represents the complex, hierarchical feedback loop that governs female reproductive function, including the menstrual cycle, ovulation, and the production of sex steroid hormones. This intricate system links the central nervous system’s command center with the peripheral endocrine gland. Proper functioning of the Ovarian Axis is essential for fertility, bone health, and overall metabolic homeostasis throughout a woman’s reproductive life and into menopause.
