Testosterone (TST) is the main male sex or reproductive hormone, which production takes place in the testicles. In particular, TST is secreted by Leydig cells as a response to LH action.
One of the main functions of TST is to stimulate the production of sperm in the Sertoli cells, a process that is regulated by FSH (follicle-stimulating hormone).
Also, Sertoli cells produce another hormone while spermatogenesis is taking place: inhibin. The action of inhibin is to send signals for the brain to stop the production of FSH, thereby creating a positive-negative feedback mechanism.
