Revolutionizing Women’s health: the quest for materials for next-generation, non-hormonal intrauterine devices

Abstract

AbstractWith over 200 million users worldwide, copper intrauterine devices (Cu-IUDs) are the world’s most popular, non-hormonal, long-acting, and reversible contraception method. Cu-IUDs cause uncomfortable side effects such as longer and heavier menstruation and cramping, all of which persist for the duration of use and often lead to early removal. With the rise in concern about potential physical and psychological side effects from hormonal contraceptive use, an improvement in non-hormonal contraceptive options is needed to alleviate discomforting side effects and inhibit costs. This perspective article provides an overview of the current state of non-hormonal IUDs and experimental factors to consider when developing new materials that have potential as alternative contraceptives, including copper alloys, zinc, iron, and passive metals. It also explores the sustainability and socioeconomic impact of advancing non-hormonal contraceptive options and considers international policy, cultural factors, and costs that must be considered when developing these options. Overall, the article highlights the interdisciplinary nature of this field, the complexities involved in creating effective non-hormonal contraceptives, and the need for innovation and equity in contraceptive care.
