GnRH Pulse Frequency

Meaning

GnRH pulse frequency refers to the specific, rhythmic rate at which Gonadotropin-Releasing Hormone (GnRH) is secreted from the hypothalamus into the pituitary portal circulation. This temporal pattern is a critical regulatory factor that differentially controls the secretion of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) from the anterior pituitary. A precise, oscillating frequency is absolutely essential for the maintenance of normal reproductive cycles and fertility in both sexes.
