In the famous Roe vs. Wade case, abortion (during the first trimester) was legalized in the US. It was and still is to this day heavily controversial. The impact it had though freed a lot of women from unsafe and life-threatening illegal abortions, as well as from having babies as the result of sexual abuse, incest, rape, etc.
"The court declared that the choice to end a pregnancy in the first trimester was solely up to the woman. In the second trimester, the government could regulate abortion, although not ban it, in order to protect the mother’s health. In the third trimester, the state could prohibit abortion to protect a fetus that could survive on its own outside the womb, except when a woman’s health was in danger."
