As far as I know, abortion was made legal in 1920 and become illegal in 1933, under Stalin but he didn't propose the anti-abortion laws 1.

Public health officials and activists as well as medical experts and personnel were largely responsible for the antiabortion campaign that subsequently unfolded

It was "legalised" (had less restrictions) in 1955 under Khrushchev. So to say it was "muh ebil Stalin" who banned abortions is fuckin take
