ABSTRACT:
A particular group of androgens is not metabolized to their 5.alpha.-reduced form in the prostate and other tissues. Thus, administration of these compounds--testosterone derivatives with a non-hydrogen substituent in the 6.alpha. or 7.alpha. position--allows one to provide androgen supplementation therapy without stimulating abnormal prostate growth. A preferred compound for use in the invention is 7.alpha.-methyl-19-nortestosterone.
