Investigation of hormonal male contraception in African men: suppression of spermatogenesis by oral desogestrel with depot testosterone.
BACKGROUND Suppression of spermatogenesis to azoospermia is required for effective hormonal male contraception, but the degree of suppression varies between ethnic groups. We here report the first study of hormonal suppression of spermatogenesis in two African centres using a regimen of oral progestogen with depot testosterone. METHODS A total of 31 healthy men (21 black) were recruited in Cape...
متن کاملMale hormonal contraception: suppression of spermatogenesis by injectable testosterone undecanoate alone or with levonorgestrel implants in chinese men.
Monthly injections of testosterone undecanoate (TU) act as a male contraceptive by reversibly suppressing spermatogenesis to azoospermia or severe oligoazoospermia in 95% of Chinese men. In 5% of Chinese men, however, monthly TU administered alone fails to suppress spermatogenesis into contraceptive ranges, or sperm "rebound," leading to occurrences of pregnancy during treatment. Since combinat...

15 صفحه اولSuppression of human spermatogenesis by testosterone implants.
Hormonally induced azoospermia is an effective, reversible form of male contraception; however, some men treated with weekly im testosterone enanthate (TE) injections fail to become azoospermic. As weekly injections cause widely fluctuating and supraphysiological testosterone levels, we tested the hypothesis that more stable, physiological testosterone levels would consistently produce azoosper...
متن کاملPlasma testosterone and testosterone binding affinities in men with impotence, oligospermia, azoospermia, and hypogonadism.
Mean plasma testosterone levels (+/- S.D.), using Sephadex LH-20 and competitive protein binding, were 629 +/- 160 ng/100 ml for a group of 27 normal adult men, 650 +/- 205 ng/100 ml for 27 impotent men with normal secondary sex characteristics, 644 +/- 178 ng/100 ml for 20 men with oligospermia, and 563 +/- 125 ng/100 ml for 16 azoospermic men. None of these values differ significantly. For 21...
