Cocktail inspired by Chinese researchers to create a contraceptive for men | Photo 1 of 6 | science



male contraception He has a promising future. Several methods pass the first stage of successful clinical trials to reduce the burden of contraception in women.

In this regard, a group of Chinese researchers found inspiration for the new method of male contraception, nothing more and nothing less than a colorful cocktail called Galaxy.

It turns out to be an alcoholic in combination whose components form the colorful layers in the glass in which it is made, which reminds the galaxy in space. Researchers have noticed that this drink forms a perfectly separate layer. However, when it is shaken or subjected to heat, the layers are broken and the components blend into one.

So the idea of ​​contraception is born that works the same way as a cocktail, but inside you deferens, which are the channels through which the seed is transferred from the testicle in the urethra.

As detailed in the article published in ACS Nano , the results obtained by team Xiaolei Wang were positive in their rats tests. They have thus created a contraceptive whose effect can be overcome by heat.

HOW DOES IT WORK?

The researchers injected four layers of different substances into you deferens male rats. The first layer consists of hydrogel, a substance that acts as a physical barrier to prevent sperm passing.

They then injected a nanoparticle of gold, which is heated by the infrared light on them. Then injected ethylenediaminetetraacetic acid (EDTA) which degrades gel and kills the sperm and seals the canal with another layer of gold nanoparticle.

In this way, sperm not only prevents it from advancing through channels, but eliminates EDTA. But it is interesting that if you want to reverse the contraceptive process, you simply have to inflate the infrared air and the gold nanoparticles will do their job, mixing with the rest of the layer and allowing the sperm to pass again.

Now that its efficacy has been demonstrated in the rat, researchers hope to test their methods in humans, as well as to guarantee the safety of the compounds used.
