In the most recent advance, revealed in April, scientists announced a major breakthrough in the development of a gel that is injected into the sperm ducts (or vas deferens) to block the release of sperm into a man’s semen.
称为亚当,水性凝胶植入物在局部麻醉下插入不到30分钟的过程。由制造商Contraline进行的最近在美国进行的25名年轻男性的试验的结果显示,凝胶阻塞了精子释放。
它被认为持续了大约两年,然后才开始崩溃,并将其从体内冲洗出来。制造商说,那时,一个男人可以如果愿意的话可以再注射凝胶。 The company claims there are no significant side-effects, but it’s not yet clear how easy it is to remove the gel surgically (rather than wait for it to biodegrade) if a patient wants to stop using it – for instance, if circumstances change and he and his partner want to start a family.
A larger, international trial is now being planned to see if the early findings can be replicated.

称为Nestorone,它含有乙酸塞替酮(一种合成的女性性激素)和睾丸激素的组合。
segesterone actate actate降低了刺激性激素,刺激spermer的激素的活性。 As this can also cause a drop in the testosterone produced by the testicles (potentially reducing libido and causing erectile problems, muscle weakness and hot flushes), testosterone is also included.
The gel gets absorbed into the bloodstream and travels to the testicles.
A study last year by美国国立卫生研究院表明,使用凝胶的222名男性中,有86%达到了每日使用15周后,使用凝胶的222名男性达到了公认的避孕点(定义为每毫升精液的精子)。 (正常的精子数量是每毫升的1500万到2亿。)
‘这是生殖医学领域中大多数人最兴奋的人。生育力在停止服用时恢复 - 这是一个大问题。但是,如果结果是积极的,那么在一年左右的时间内,英国的男性可以可以使用内斯托酮。’
