Spermatogenèse

The process of sperm production that occurs in the seminiferous tubules.

Testosterone

A hormone produced by Leydig cells that is crucial for maintaining secondary sexual characteristics and the genital tract.

AMH

A hormone (Anti-Müllerian Hormone) produced by Sertoli cells.

GnRH (Gonadolibérine)

A neurohormone secreted by the hypothalamus that influences the pituitary gland.

Gonadostimulines (FSH and LH)

Hormones secreted by the pituitary gland that influence the testicles.
