No, it didn't. Communist dogma railed against Western decadence and sexual corruption. Pornography was illegal, for example. "Free love" and other Western concepts were denounced by the leadership.
The abortions weren’t a bug; they were a feature of the government deployment of “sexual liberation” as an implement of social control.
Abortion was used as birth control because the communist system was terrible at providing effective birth control such as condoms of the pill. Plus, the future looked so bleak that Russian women were not eager to bring kids into such an environment.
Actually Philo is correct. The Soviet Revolution started out with a free sex/get rid of all bourgeouis morality platform and taught kids that anything goes, that traditional family life was crippling. But the kids turned out to be such animals that they had to change course.
The Communists made divorce, abortion and homosexuality legal. Condemning the visible and obviously forseeable consequences was merely the standard totalitarian tactic of blaming the victims for the necessity of their abuse.
