It’s time for guys to woman up.
(Basically, a normal menstrual cycle for women.)
While the birth control turned out to be nearly 96 percent effective, the men reported negative side effects. The birth control injections consisted of progestogen and a synthetic testosterone taken every eight weeks to suppress sperm.
“Of these 20, six men discontinued only for changes in mood, and six men discontinued for the following single reasons: acne, pain or panic at first injection, palpitations, hypertension, and erectile dysfunction. Eight men discontinued for more than one side effect, including multiple reasons related to changes in mood,” researchers from the University of Edinburgh detail in the study.
Still, of the 266 men who took part in the study for 56 weeks before it ended early, just four pregnancies occurred, and the researchers found it to be highly effective.
“The study found it is possible to have a hormonal contraceptive for men that reduces the risk of unplanned pregnancies in the partners of men who use it,” one of the study’s authors, Mario Philip Reyes Festin, MD, said in a press release. “Our findings confirmed the efficacy of this contraceptive method previously seen in small studies.”

And on the bright side, other than those 20 men, 75 percent of the participants said they would be willing to use the contraceptive after the trial ended, though the researchers said it needs more work before it’s made available.
“More research is needed to advance this concept to the point that it can be made widely available to men as a method of contraception,” Festin said. “Although the injections were effective in reducing the rate of pregnancy, the combination of hormones needs to be studied more to consider a good balance between efficacy and safety.”
