It's also patriarchy at work that men would never tolerate even 1/10th of the risks women face in preventing pregnancy. Look at the responses to getting a small injection - "nobody would ever do that"! Hormonal birth control is great for some women, but terrible for others. It can also cause suicidality, but the side effects are routinely downplayed because women are expected to "deal with it". There's more research into how to keep men's hair from falling out and keep their dicks hard than there is into the most comfortable way to insert IUDs, or the side effects of hormonal birth control.
