Fetal preputial glands from 14- to 17-day old mouse embryos undergo comparable growth, branching, and display similar degrees of cytodifferentiation when cultured in vitro on medium lacking hormones, on this medium in the presence of either of the fetal gondas, and on medium supplemented with testosterone dipropionate. Conversely, morphogenesis of these analgen is markedly suppressed by estrogen and an anti-androgen, Cyproterone acetate. These observations demonstrate that acquisition of androgen-sensitivity is a late event in the morphogenesis of the preputial gland and correlate with the developmental properties of preputial mesenchyme as demonstrated in earlier studies on the epithelio-mesenchymal interaction.

A low dose of Cyproterone acetate (CPA; 1 mg/kg body weight/day for 70 days) was administered to adult male rhesus monkeys to assess its effects on testicular and epididymal structure and function in a nonhuman primate species. CPA caused extensive degenerative changes in morphology of seminiferous, efferent duct, and epididymal epithelia, including decrease in diameter of seminiferous and epididymal tubules and their lumen, height of epididymal epithelium, and an increase in intertubular connective tissue. The protein profile of spermatozoa showed alterations during their epididymal transit in control and CPA-treated monkeys. In CPA-treated animals, 19 polypeptides were acquired and nine were eliminated during epididymal transit in contrast to acquisition of 12 and loss of 14 polypeptides in control animals. Treatment with CPA also resulted in the appearance of 14 new polypeptides in epididymal cytosol and luminal fluid, probably of lysosomal origin. The protein pattern of caput and cauda epididymal tubule cytosol, maintained in organ culture and exposed to 100 microM CPA for 3 days, showed absence of eight polypeptides. These results indicate that even at the low dose used in this study, CPA has caused spermatogenic arrest, degenerative changes in the epididymal structure, and alterations in epididymal and sperm protein profile. Suppression of serum testosterone levels indicates the need for androgen supplementation if CPA is to be used for male contraception.
