Sex hygiene films, one of the early styles of sexploitation, follow the formula of 50s family melodrama narrative while emphasizing topics such as sex, pregnancy, contraception, and STDs within the context of health and hygiene. William Beaudine's Mom and Dad serves as the archetype of the sex hygiene films and is a standout in this genre, achieving massive box office success and grossing millions of dollars. In the film, a straight A teen girl Joan becomes pregnant after her first sexual encounter. Overwhelmed with fear, she is devastated by the sudden death of her boyfriend in an accident. The movie interweaves Joan's story with lectures from sexual health experts and educational footage, presenting unfiltered medical imagery such as actual childbirth scenes and genitals affected by venereal diseases. Sex hygiene films were also popular for their unique screening pattern: during the intermission, a sexual health expert(played by an actor) starts lecturing the audience by showing medical films that gained traction. Sex education films still held popularity until the 70s, evolving into ‘how to have better sex for couples.’ (Jin PARK)
