The scientific community has come closer than ever to finding an effective birth control method for men.
A study from the University of Edinburgh, testing a hormonal birth control injection on men was found to be 96 percent effective, that’s only slightly lower than the 99.9 percent achieved by women’s birth control.
Unfortunately, the study was halted when participants dropped out, many due to “mood swing” related side effects.
The study tracked 320 men between the ages of 18 and 45 as they received regular injections of two hormones over a 56 week period. The hormones administered were testosterone and progestogen. Progestogen lowers sperm count and also effects hormone levels, hence the testosterone to offset those effects. The men received two injections every eight weeks.
Of the 20 men that left the study, causing it to end prematurely, 14 of them were due to mood related side effects. The other 6 participants cited acne, pain or panic experienced when receiving the injection, palpitations, hypertension and increased libido.
For women who have long suffered the brunt of contraceptive responsibility, the side effects may sound similar to their own experience with hormonal birth control.
Earlier this month Danish researchers released study results confirming the long-held suspicion that there is a link between hormonal birth control and depression in women.
“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,” researcher and co-author of the study, Mario Philip Reyes Festin, MD 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.”
After the 52-week study 75 percent of participants said they would be willing to use this method of contraception.
