Adult male rats were injected intraperitoneally with 2 mg, 4 mg and 6 mg Cis-diamminedichloroplatinum (DDP) per kg body weight. The animals were then sacrificed on the 7th, 24th or 35th day. Two specimens of testis from each rat were stained by H.E. technique, then the Pachytene primary spermatocytes and Sertoli cells in the cross sectioned tubules at stage IV-V, IX-X and XIII-XIV were counted. Significant decrease of Pachytene/Sertoli(P/S) valueinstage IX-X tubules on the 24th day (p less than 0.01) suggests that DDP has a cytotoxic effect on early differentiated type A spermatogonia (A1).
