Mechanism of action of alpha-chlorhydrin on the testes and caput epididymidis of rat, gerbil (Meriones hurrianae), bat and mouse.

Chronic administration of alpha-chlorhydrin caused lesions of rat, gerbil and bat testicles selectively. The seminiferous epithelium became systematically depleted of spermatogenic elements. alpha-Chlorhydrin did not produce lesion of the caput epididymidis. Sloughing of the epithelial lining did not occur. No obstruction of the lumen of the epididymal duct was seen. The growth of androgen-dependent organs, i.e. seminal vesicles, epididymis and levator ani muscles was suppressed. alpha-Chlorhydrin caused no response directly on the epididymides. Subcutaneous or oral administration of alpha-chlorhydrin for a period of 3-5 weeks caused no response in the testes and epididymides of the mouse.
