This is a product of the Japanese Pinku eiga film genre, which are basically sexploitation films, which flourished in the 1960s. I wanted to see this as I was intrigued by Adachi who was a prominent writer and director in the Japanese New Wave film movement, producing pinku films and documentaries. Adachi became part of VAN, a sort of loose anarchist artist group which operated a large studio in Tokyo. He stopped making films in the early 1970s and joined the Japanese Red Army, an armed militant organization, to organise terror attacks. The film is set in the office of a strange gynaecologist named Marukido Sadao - a play on Marquis de Sade. Sadao is obsessed with birth control and the concept of separating sexual pleasure from reproduction. Post-war Japan saw an influx of basukon eiga: sex education films that, in order to bypass censorship, purported to teach but were obviously only out to tantalise their audience. Abortion is a parodic take on these films. It's... well, it's... interesting.
