Because this steroid is alkylated in position 17, toxic effects on liver function can not be excluded. Danazol offers no advantages as compared with other anabolic steroids; rather, disadvantages. Numerous experiments of this type have been performed during the last 40 or 50 years. The outcome in each case was more or less identical: with a certain dose of an androgen or anabolic steroid it is possible to inhibit spermatogenesis without interfering with other androgen-dependent func­ tions, including libido (potentia coeundi) and accessory sexual glands. On the basis of this pharmacological-endocrinological background, androgens and anabolic steroids can be used for male fertility control, and several clinical trials have been performed during the last 10-15 years. Some of 1 these studies 2-23 are mentioned in Table 2.
