Research Article: Clinical Manifestations, Genetic Variants and Therapeutic Evaluation in Sporadic Chinese Patients with Idiopathic Hypogonadotropic Hypogonadism
Introduction:
The roller coaster-like pulsatile secretory activity of gonadotropin-releasing hormone (GnRH) released by GnRH neurons in the mediobasal hypothalamus controls reproductive function during human lifespan. Notably, GnRH secretory activity lapses into silence throughout childhood until the onset of puberty. Its deficient synthesis, secretion, or action directly causes hypothalamic-pituitary-gonadal (HPG) axis hypofunctioning, defining hypogonadotropic hypogonadism (HH), which typically manifests as absent or impaired…
