The adult male rats were treated with different doses of cypermethrin by gavage for consecutive 15 days. The weights of prostates and daily sperm production decreased. Seminiferous tubule changes included atrophy and distortion, reduction and deformation of spermatogonia and spermatocyte. Ultrastructural changes included disrupted cellular junctions, abnormal nucleus, necrosis of spermatogonia, spermatocytes and Sertoli cells. AR expression and serum testosterone reduced. Cypermethrin may impair the seminiferous tubules and spermatogenesis, which can be attributed to the reduced AR expression.
