People with uteruses have multiple contraceptive options if they want to take birth control, including the Pill, hormonal and copper intra-uterine devices or IUDs, implants, and injections. People with male bodies, however, have far fewer options, long a source of frustration for partners who can get pregnant. They're basically restricted to either condoms or vasectomies, which block sperm from reaching semen. While a lot of progress has been made on giving people with penises more options, and several promising new techniques are being tested in 2019, experts tell Bustle that there's a long way to go — and many obstacles in the way of successful male contraceptive development.
