GlossaryHypothalamic-Pituitary-Gonadal Axis (HPG Axis)

regulates reproductive hormones through interactions between brain and gonads

The Hypothalamic-Pituitary-Gonadal (HPG) Axis is a complex set of interactions among the hypothalamus, pituitary gland, and gonads (ovaries in females and testes in males) that regulate reproductive function and hormone production. This system controls the release of hormones like GnRH (gonadotropin-releasing hormone), LH (luteinizing hormone), and FSH (follicle-stimulating hormone), which are crucial for processes such as puberty, menstrual cycles, and sperm production.
