Norethisterone enanthate plus testosterone undecanoate for male contraception: effects of various injection intervals on spermatogenesis, reproductive hormones, testis, and prostate.
The goal of this study was to find the most favorable injection interval of norethisterone enanthate (NETE) plus testosterone undecanoate (TU) in terms of gonadotropin, sperm suppression, and prostatic effects. Fifty normal men were randomly assigned to receive NETE 200 mg plus TU 1000 mg every 8 wk (n = 10), every 12 wk (n = 10), every 6 wk for 12 wk and then every 12 wk (n = 10), and every 6 ...
متن کاملPharmacokinetics of testosterone undecanoate injected alone or in combination with norethisterone enanthate in healthy men.
Long-acting injectable testosterone undecanoate (TU) is a promising androgen for male hormonal contraception. As a prerequisite for a planned multicenter male contraceptive efficacy study, we studied the pharmacokinetics of 2 doses of TU alone or in combination with norethisterone enanthate (NETE) in a prospective 2-center study, randomized for TU dose in each center. Twenty healthy male volunt...
متن کاملMale hormonal contraception: effects of injections of testosterone undecanoate and depot medroxyprogesterone acetate at eight-week intervals in chinese men.
Surveys indicate that one form of acceptable male hormonal contraception would consist of injections given at 2- to 3-month intervals. This report describes a study of depot medroxyprogesterone acetate (DMPA) and testosterone undecanoate (TU) injected at 8-wk intervals for suppression of spermatogenesis in healthy Chinese men. After screening, 30 healthy volunteers were enrolled and randomly as...
متن کاملEffects of carbamazepine on male reproductive hormones
Background :Reproductive endocrine disorders and sexual dysfunction are common among men with epilepsy. We investigated sexual hormone serum levels among men with newly diagnosed epilepsy, before starting any antiepileptic drug (AED), and then after starting carbamazepine (CBZ), to determine the role and effects of epilepsy versus CBZ in creating reproductive endocrine disorders. Methods : ...
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...
