title: Effect of sulphapyridine on male fertility in the rat.
abstract: Male rats administered sulphapyridine (60, 120 and 250 mg/kg) for 60 days demonstrated no change in body weight and testicular weight. However, there was a decrease in the weight of the epididymis. Motility and sperm reserves were reduced and were evident from fewer implantation sites and number of pregnancies. Furthermore, sulphapyridine did not show any effect on the histoarchitecture of the testis or epididymis. Serum levels of testosterone in the treated rats were comparable to their respective controls. Morphological abnormalities as revealed by scanning electron microscopic studies clearly demonstrated the detrimental effects of the drug.
