据西雅图华盛顿大学报道一种可逆的男性睾酮避孕药睾酮庚酸盐(暂时阻止精子产生)已应用于250例男性临床试验,其避孕机理类似女性口服避孕药(通过脑垂体释放激素阻止排卵)。避孕药的初步试验表明:50～60%男子的精液中无精子。然而,Bremner的观察偶见精液中有少许精子。目前,对250例男子的临床试验将证实上述问题。该避孕药应注射使用,因为激素口服,保持活性时间短。每周注射200mg,这种避孕药并非没有副作用,尽管很小,但大多数受试者注射后,体重有少许增加。睾酮能使男性肌肉增加和钠潴留,几例出现痤疮。研究者预测:使用该药能降低男子性
According to the University of Washington, Seattle, a reversible male testosterone contraceptive testosterone (temporary inhibition of sperm production) has been applied to 250 male clinical trials, the contraceptive mechanism similar to female oral contraceptives (ovulation by the pituitary gland to prevent ovulation). Preliminary tests of contraceptives show that 50-60% of men have no sperm in their semen. However, Bremner’s observations occasionally have a few sperm in the semen. At present, the clinical trials of 250 men will confirm the above problems. The contraceptive should be used by injection, because hormone oral, keep the activity time is short. Weekly injection of 200mg, this contraceptive is not without side effects, although small, but most subjects injected a slight increase in body weight. Testosterone can increase male muscle and sodium retention, with acne in a few cases. Researchers predict: the use of the drug can reduce the man sex
