Condom suffered the strongest opponent: male birth control pills or condoms-the advent, the pill-IT information

Researchers say, is closer to developing a safe male contraceptive.

According to the United Kingdom, the independent reported, scientists believe they have closer to develop a safe male contraceptive pill. After the female birth control pill 50 years, researchers have not yet found a way to make the men in temporary infertility, without serious side effects.

However, experts at the University of Minnesota in the United States Chemical Society annual meeting, in this area of research has been major progress. Scientists have reported that before they have developed minor changes the male pill, make it better and lasting, and are more likely to take it.

Gunda Georg, head of the research team describes a male birth control pill went on sale in the first standards to be achieved. She claimed: " male pill must be dissolved, so that it can be taken orally. Its effect should be quite fast, and will not reduce sexual desire. In addition even if the men taking the drug for dozens of years, should also be safe . ”

Because some users will eventually want to have kids, so it will impact on fertility is reversible, and adverse effects to sperm and embryos without delay. Their study is established on the basis of a study last year, researchers identified a biological enzyme of sperm into eggs.

Involved in the study of cell biology professor John Herr said: "from the molecular level how can learn more about sperm and eggs are bundled into one, will be found to destroy or prevent this process. "Applied already before the male hormone testosterone, libido is not affected because it can subject to temporary birth control.

Team researcher Jillian Kyzer said: "after taking a dose, testosterone can cause infertility, but it does not play a role in up to 20% of men, and it can cause side effects, such as weight gain and lowering good cholesterol. ”

套套遭遇最强对手：男性避孕药或将问世 - 安全套,避孕药 - IT资讯

研究人员声称，已经更接近于研制出一种安全的男性避孕药。

据英国《独立报》报道，科学家们相信他们已经更接近于研发出一种安全的男性避孕药。在女性避孕药问世50年之后，研究人员尚未找到一种方法使男性在没有严重副作用的前提下实现临时不育。

然而明尼苏达州大学的专家们在美国化学学会年度会议上提出，他们在这一领域的研究已经获得了重大的进步。科学家们报告称，他们已经对之前研究出的男性避孕药进行了细微的改变，使它变得效果更佳持久，而且更容易服用。

研究团队的负责人Gunda Georg详细描述了一种男性避孕药在上市销售前所要达到的标准。她声称：“男性避孕药必须是可溶解的，这样它就能够进行口服。它的药效也应当相当的迅速，而且不会降低性欲。此外即使男性服用这种药物长达数十年，也应当是安全的。”

由于部分使用者最终还是会想要孩子，因此它对于生育能力的影响将是可逆的，而且对于精子和胚胎没有延迟的不良作用。他们的这项研究是建立在去年一项研究的基础上，当时研究人员识别出了精子用于进入卵子的一种生物酶。

参与这项研究的一位细胞生物学系教授John Herr称：“从分子水平详细了解精子如何能够与卵子捆绑并进入其中，就有机会发现能够破坏或者阻止这一过程的分子。”雄性激素睾丸素之前已经在得到了应用，因为它能够在不影响性欲的前提下临时避孕。

研究团队的研究人员Jillian Kyzer称：“服用一定剂量后，睾丸素会导致男性不育，但是它在高达20%的男性中并不起作用，而且它能够带来副作用，比如说体重增加和降低良性胆固醇等。”
