Abstract

Spermatogenesis is a complex process, and previous studies have clearly established the role for testosterone in its maintenance. However, the role of FSH remains controversial, although several lines of evidence suggest its importance in initiation of spermatogenesis. In the present study, the relative roles of FSH and LH have been evaluated using specific antisera capable of neutralizing endogenous hormones in adult male rats following ethanedimethylsulphonate (EDS) treatment. Restoration of spermatogenesis in EDS treated rats was monitored following FSH or LH deprivation by histological analysis and flow cytometry. Deprivation of FSH resulted in a reduction of seminiferous tubule diameter and spermatogonial number, which was much more drastic than that observed following LH deprivation. More importantly, FSH deprivation was associated with a significant reduction in the number of pachytene spermatocytes. These results provide evidence for a definite role for FSH in regulation of spermatogenesis, in addition to confirming the role of LH in spermatogenesis via testosterone.
