Male contraceptive? The pill limits the production of spermatozoa


Medicine begins to be tested




A new era is approaching for family planning. For the first time, a male contraceptive pill that acts without hormonal interference is strictly tested in clinical studies. The promising initial results, obtained in studies with non-human mice and primates, indicate that the mixture called YCT-529 has shown a considerable ability to limit the production of sperm with apparently mild side effects.

In the experiments conducted on male mice, the contraceptive began to exercise its contraceptive effect in a period of a month after the start of the administration. The tablet was able to reduce pregnancy rates in their female partners of almost 100%. As regards male monkeys, although a higher dosage of the drug has been requested, a quick and significant reduction of the sperm tag has been observed without significant side effects.

“A safe and effective male pill will offer more options to couples for birth control. It will allow a more beautiful division of family planning and will give men’s reproductive autonomy,” Gunda Georg at the United States at Sciencealert said at the Minnesota University.

The search for non -hormonal alternatives arises in response to the challenges faced by the previous attempts to contracept the hormonal men. As for female pills that modulate sex hormones, male versions with this approach can trigger unwanted side effects, such as weight changes, depressive paintings or raising “bad” cholesterol levels. In previous studies, the emergence of these unexpected events has often led to the interruption of clinical tests of effective methods.

The study also shown that the tested animals recovered their fertility immediately after interrupting the use of the drug. Even the drug has not caused significant changes in three important hormones for the production of spermatozoa: testosterone, FSH and initial B.
