Androgens and FSH is there primacy for spermatogenesis

Similar to testosterone, FSH is also able to initiate, maintain and reinitiate qualitatively normal spermatogenesis. This should not be surprising since both hormones act via the same intratubular cell, the Sertoli cell. The evidence is compelling for a synergistic and additive effect of testosterone plus FSH on spermatogenesis and germ cell development. These findings suggest that testosterone and FSH - at least to some extent - stimulate different factors and processes. If the mechanism of action were identical for testosterone and FSH, a competitive rather than an additive effect on spermatogenesis would be expected. Therefore, a primacy of adult spermatogenesis for testosterone or FSH does not exist, rather a true synergism prevails.
