There’s a new male birth control in town and it’s called a Sac Inhibitor! Male birth control options have been pretty limited, with barrier methods like condoms or more recently vasectomies being the only real options. However, this new drug is a fast-acting, temporary birth control option that has been studied in mice and has been shown to be effective after just 30 minutes of an injected dose and wears off after a few hours. This makes it a great option for people who don’t want to commit to a vasectomy.
