A New Birth Control Method Has Been Developed For Men

Prolonged exposure of the testicles to extreme heat to infertility whether or not and works flawlessly of male contraception How to do (birth control) is a subject that has been in the focus of the scientific world for a while. Overheating laptops can affect sperm quality if they sit on your lap for hours; Male birth control methods, on the other hand, are basically limited to vasectomy and condoms, unlike women who have various methods such as pills, spirals and hormone injections.

But what if heat-exposed testicles were a solution for male contraception from the start? According to a study conducted at the Institute of Reproductive Medicine at Nantolog University in China, the answer to male birth control is, stored in heat it could be.

Possible temporary, reversible reduction of fertility in men

According to the results of the experiments on mouse testicles, the magnetic field generated as a result of wrapping the testicles with an electric coil and heating the testes filled with nanoparticles, improves fertility. temporary and reversible reduction possible.

A 2013 study first conducted experiments by injecting modified gold nanorods with near-infrared irradiation into mouse testicles. As a result of this study, it has been determined that this method is more than surgical castration (sterilization) in order to control the excessive reproduction of domestic and stray animals. more convenient, efficient and cheaper turned out to be.

In the research conducted in 2021, the subject went deeper and was non-invasive; Studies have begun on reversible male birth control. Researchers trying to solve some problems encountered in previous studies, in the new study; Injecting very small, precious metal pieces into the testicles painlessly and not causing poisoning, and the testicles without causing skin damage He started looking for ways to warm up.

This time, scientists trying to use magnetic iron oxide nanoparticles that the body can destroy later; They injected the nanoparticles into the mice intravenously and then placed them next to the testicles for four hours to draw the particles into the testicles. magnet they placed. After one to four days of injections and magnets, they wrapped an electric coil around the testicles. This, in turn, regenerates the iron oxide stored in the balls with the magnetic field produced from the current. between 36 and 45 degrees heated to temperatures.

After this process, the sperm count of the mice decreased; The fertility of those heated at lower temperatures was found to be higher after 60 days. he came back observed. For this development, researchers “The number of offspring born to pregnant mice was almost the same and no visible morphological defects were observed in all offspring” used the phrases.

Testes that warmed over 45 degrees could not heal

In tests where more heat is applied, the testicles become atrophied and there is a significant difference in some testicles depending on how much iron oxide is injected or how much they are heated. color changes was observed. It was observed that the testicles, which were heated above 45 degrees, were severely damaged and could not heal at the end of the 7th day.

It may sound difficult to have human males voluntarily inject a magnetic substance into their testicles and then wrap a heating coil around them and kill their sperm for a few months; reproduction of animals It is also thought to be an attractive option to control.

On the other hand, it is a big problem that all the responsibility of the birth control department, except for the condom, which most men do not like to use, is placed on women as if they are getting pregnant on their own. Although the birth control methods available for women reduce the chance of getting pregnant at high rates, the pregnancy factor does not completely disappear and pregnancy can occur as a result of the man not taking the necessary protection. Therefore, for both parties an appropriate method of birth control development seems to be the only solution that can eliminate this problem.
