1 Zygote's life matters more than 9 months of woman's pain, but also, 9 months of women's pain matters more than 3 days of men's pain.
Vasectomies pretty much solve unplanned pregnancies and abortions.
Men should get vasectomized before they do vaginal sex on someone with the potential to get pregnant. Any man that says, "I don't want to get a vasectomy because my body, my choice", you have no business then telling women they should be banned from abortions based on the goal of preventing fetal homicide (because you are unwilling to make a smaller sacrifice to prevent fetal homicide).
