Its use as a fertility aid is where Proviron was really emphasized in medical literature. This is because while almost all anabolic/androgenic steroids are known to cause temporary infertility, Proviron in normal therapeutic dosages actually barely suppresses endogenous gonadotropins (LH and FSH) when utilized. However, Proviron is poorly misunderstood as a compound that increases LH, which it does not do. Instead, research has demonstrated that Proviron provides the androgenic effects necessary for spermatogenesis in specific areas in the testes.
