title: Introduction: 50 years of evolution of contraceptive medicine.
abstract: The science of contraceptive medicine and reproductive medicine are similar. At present contraceptive medicine has moved beyond understanding the mechanism of action of steroid hormones with the introduction of many safe and effective methods. Long-acting reversible contraceptives are increasing in acceptance and providing very high efficacy. The science has pivoted toward optimization of family planning in selected high-risk populations, such as those with a high-risk of thrombosis, as well as addressing the challenge of obesity. The pipeline for male and female related methods will continue to advance the science and public health impact.
