The male contraceptive It has a promising future. Several methods go through the first stages of successful clinical trials to reduce the burden of contraception in women.

In that direction, a group of Chinese researchers found inspiration for a new method of male contraception, nothing more and nothing less than a a colorful cocktail named Galaki.

It turns out that it is a combination of alcoholics whose components shape the colorful layers in the glass in which they are being prepared, which resembles the galaxy in the space. The researchers noted that this drink forms perfectly separate layers. However, when shaking or undergoing heat, the layers are broken and the components are blended into one.

Thus, the idea of ​​contraception, which functions in the same way as a cocktail, is born within the deferens, which are the channels through which the seeds are transmitted from the testes to the urethra.

As detailed in the article published in ACS Nano , the results obtained by the Ksiaolei Vang team were positive in their rats tests. Thus, they created a contraceptive, the effect of which can be reset by heat.

HOW IT WORKS?

The researchers injected four layers of different substances into your male rat deferens. The first layer consists of hydrogel, a substance that acts as a physical barrier that prevents the passage of sperm.

Then they injected a layer of nanoparticles of gold, which are heated by radiating infrared light on them. Then they injected ethylenediaminetetraacetic acid (EDTA), which breaks the gel and kills the sperm and seals the channel with another layer of gold nanoparticles.

In this way, spermatozoids are not only prevented from progressing through the channels, but by eliminating EDTA. But it is interesting that if you want to reverse the contraceptive process, you simply need to warm up with infrared rays and the nanoparticles of gold will do their job, blending with the rest of the layer and allowing the passage of sperm.

Now that its effectiveness has been proven in rats, researchers are hoping to test their method in humans, as well as to guarantee the safety of the compounds used.
