HPG Axis Monitoring

Meaning

HPG Axis Monitoring is the clinical process of systematically tracking the function and output of the Hypothalamic-Pituitary-Gonadal axis, the central regulatory pathway for reproductive and sexual health hormones. This involves serial measurement of key biomarkers, including Gonadotropin-Releasing Hormone (GnRH) surrogates, Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), and target sex steroids like testosterone and estradiol. Effective monitoring is essential for diagnosing conditions such as hypogonadism or polycystic ovary syndrome (PCOS) and for precisely titrating hormone replacement therapies to maintain optimal physiological balance.
