HPG Axis Dysregulation

Meaning

HPG Axis Dysregulation refers to any functional disturbance or imbalance within the Hypothalamic-Pituitary-Gonadal axis, the primary neuroendocrine system governing reproductive and sexual development and function. This dysregulation can manifest as abnormal secretion patterns of gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), or sex steroids like testosterone and estrogen. Clinically, this imbalance is associated with a spectrum of conditions, including infertility, menstrual irregularities, and symptoms of hypogonadism in both sexes. Restoring the axis’s precise feedback control is a central goal in hormonal optimization.
