Gonadal Axis

Meaning

The Hypothalamic-Pituitary-Gonadal (HPG) axis, a critical neuroendocrine pathway that controls reproductive function and the production of sex hormones in both males and females. This integrated axis involves the hypothalamus, the pituitary gland, and the gonads (testes or ovaries). It is the central regulatory system for fertility, sexual development, and the maintenance of sex-specific physiological traits throughout the lifespan.
