Testosterone inhibits the secretion of GnRH [1], creating a direct negative feedback relationship. Additionally, low GnRH levels in secondary hypogonadism lead to reduced testosterone production [2] and [3], highlighting their interconnected roles in the hypothalamic-pituitary-gonadal axis.

claimSecondary hypogonadism in human males results from a disruption in the hypothalamic-pituitary axis where low gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), or follicle-stimulating hormone (FSH) leads to low testosterone and impaired spermatogenesis.

claimThe secretion of GnRH is inhibited by testosterone, estrogen, estradiol, and prolactin.

claimIn cases of secondary hypogonadism, Leydig and Sertoli cells remain functional and intact but cannot exert their effects due to a lack of proper stimuli (GnRH, LH, or FSH), resulting in low testosterone levels or loss of spermatogenesis.
