More than 160 million women worldwide who need contraception are unable to access it, according to the largest study of its kind.
There has been a huge increase in contraception use globally since 1970, driven by a major shift from the use of less effective, traditional methods to more effective, modern contraceptives, including oral pills, IUDs, and male and female sterilisation, the research reveals.
