HPA-HPG Axis Crosstalk

Meaning

HPA-HPG Axis Crosstalk describes the bidirectional communication and mutual regulatory influence between the Hypothalamic-Pituitary-Adrenal (HPA) axis, governing stress response, and the Hypothalamic-Pituitary-Gonadal (HPG) axis, controlling reproductive function. Chronic activation of the HPA axis, characterized by sustained high cortisol, is known to suppress GnRH release, thereby impacting testosterone and estrogen production. Recognizing this interplay is vital for managing conditions where stress impacts fertility or libido.
