[19] Physiologic levels of prolactin in males enhance luteinizing hormone-receptors in Leydig cells, resulting in testosterone secretion, which leads to spermatogenesis. [20] Prolactin also...

Both the FDA and the AUA suggest that TT be used to treat conditions you are born with, such as Klinefelter syndrome. You also may need TT if you harm or lose your testicles.
