Men and Women Need a New Male Contraceptive

摘要

Despite many years of research, we still don't have any new contraceptive options for men. Many women might welcome the opportunity to share contraceptive responsibilities with their partners, and family planning discussions between men and women might change in unexpected ways. However, while women have a dazzling variety of contraceptives to choose from (Table), men still have only two modern methods: condoms or vasectomy. Condoms are commonly used by young men who have not yet begun living with asteady partner, or by couples who are able to deal with the inconveniences of condoms. However, most men consider condoms to be uncomfortable and clumsy to use. Some men consider female condoms more comfortable and acceptable, but they are more expensiveand not as widely available, and neither type of condom is considered highly effective in terms of pregnancy prevention.
