Between 1800 and 1975, sexuality in the West was transformed. Hera Cook shows how the growing effectiveness of contraception gradually eroded the connection between sexuality and reproduction. The increasing control over fertility was crucial to the remaking of heterosexual physical sexual behaviour and had a massive impact on women's lives. Dr Cook charts how, why, and when attitudes towards sex changed from the repression of the nineteenth century to the sexual revolution of the 1960s.
