HPG Axis Integrity

Meaning

HPG Axis Integrity refers to the functional health and structural soundness of the Hypothalamic-Pituitary-Gonadal axis, the master regulatory system for reproductive and sexual health. This integrity is precisely defined by the seamless, bidirectional communication and appropriate, sensitive feedback mechanisms between the brain, the pituitary gland, and the ovaries or testes. Optimal HPG axis integrity is absolutely essential for fertility, the appropriate production of sex hormones, and the long-term maintenance of secondary sexual characteristics throughout life.
