In the final stages of the study, the contraceptive pill is intended for a male audience.
The key feature is that it will not contain hormones, as it happens for the female correspondent.
The male contraceptive pill was found to be 99% effective in preventing pregnancy in mice, with no apparent side effects. The studies were conducted by the University of Minnesota and a team of researchers, who administered the treatment — a daily dose of a molecule called YCT529 — to mice over four weeks, at the end of which sperm count plummeted. Once the treatment was stopped, the mice returned to normal reproduction.
Human trials are expected to begin by the end of the year.
