The hypothalamic–pituitary–testicular (HPT) axis is the central regulatory system governing male reproductive and endocrine function. This axis coordinates hormonal signaling between the brain and testes to maintain spermatogenesis and testosterone production.
Disruption of the HPT axis may occur due to stress, systemic illness, medication use, or congenital abnormalities. Such disturbances can lead to infertility, hypogonadism, and sexual dysfunction.
In andrology, evaluation of the HPT axis is essential for identifying the origin of reproductive disorders and tailoring erotic appropriate therapeutic strategies.
