Hormone Side Effects Cut Study Short
According to a study published recently in The Journal of Clinical Endocrinology & Metabolism, hormonal birth control shots for men could be an effective form of contraception. However, the study was halted because of side effects, including depression, mood changes, and others.
Three-hundred twenty healthy men between the ages of 18 and 45 participated in the study. All of the men were in monogamous relationships with female partners. They received injections of synthetic hormones—testosterone and progestin—which lowered sperm production by reducing the amount of testosterone produced by the body.
The male hormone injections were found to be 96 percent effective at preventing pregnancy. Seventy-five percent of participants reported that they would be willing to use this form of birth control if it was available, but the study was discontinued for safety reasons. Reported side effects were similar to those experienced by women who are on hormonal birth control.
