Male birth control has to be safer and have fewer side effects than letting women carry the burden of birth control.
I mean, I don’t think this is such a high bar to pass.
Pregnancy is bad but I’d argue the consequences of 18 years of unwilling parenthood far outstrips the consequences of 9 months of pregnancy. The consequences for those 18 years impact both parties.
Furthermore, men have almost zero agency of what happens in the case of an unintended pregnancy. A man can’t say, “this would ruin my life, I am going to choose not to have the baby.”
That makes the risk quite high for a man, IMO, and the only way to take agency over that risk is male birth control.






Yup some Daoist secs historically believed semen contains life force. Via “retention of the semen”, a man could maintain his vital life force and slow aging. However, having sex would generate life force. So you could extend your life by having sex as much as possible while controlling how often you ejaculate.
