Birth Control Pill for Men Men may soon be able to bear their share of family planning. Since the advent of the birth control pill in the 1960s, women have used pills, patches, and implants to avoid becoming pregnant, but guys had only two choices a condom or a vasectomy. That may soon change. Researchers are testing forms of hormonal contraception for men that would temporarily stop the production of sperm. Formulations include an androgen and a progestin, which work together to block the production of sperm in much the same way female birth control pills prevent eggs from being released. These formulations have been even more effective at preventing pregnancy than condoms, but scientists have questioned whether or not the effects are permanent. A study that reviewed male contraceptives has shown that after quitting the contraceptive, most men become fertile once again within five months, and 90 percent were fertile within a year. Still, male contraception wont be as simple as taking a pill each day. Dr. Peter Liu, who co-authored the study, thinks male contraception will consist of a monthly injection of an androgen, such as testosterone, coupled with a daily pill or implanted capsule of progestin. Liu predicts the new form of male contraception will be popular once it is available. Couples want to share the responsibility of family planning, and this allows them to do it, said Liu.
