Global research and learning agenda for building evidence on contraceptive-induced menstrual changes for research, product development, policies, and programs.

Background: Contraceptive-induced menstrual changes (CIMCs) can affect family planning (FP) users' lives in both positive and negative ways, resulting in both opportunities and consequences. Despite this, and despite the important links between FP and menstrual health (MH), neither field adequately addresses CIMCs, including in research, product development, policies, and programs globally. Methods: In November 2020, a convening of both MH and FP experts reviewed the existing evidence on CIMCs and identified significant gaps in key areas. Results: These gaps led to the establishment of a CIMC Task Force in April 2021 and the development of the Global Research and Learning Agenda: Building Evidence on Contraceptive-Induced Menstrual Changes in Research, Product Development, Policies, and Programs Globally (the CIMC RLA) , which includes four research agendas for (1) measurement, (2) contraceptive research and development (R&D) and biomedical research, (3) social-behavioral and user preferences research, and (4) programmatic research. Conclusions: Guided by the CIMC RLA, researchers, product developers, health care providers, program implementers, advocates, policymakers, and funders are urged to conduct research and implement strategies to address the beneficial and negative effects of CIMCs and support the integration of FP and MH. CIMCs need to be addressed to improve the health and well-being of women, girls, and other people who menstruate and use contraceptives globally.

Drospirenone: a Latin American perspective for oestrogen-free oral contraception.

AIM: Combined hormonal contraceptives, despite their high efficacy, are associated with an increased relative risk of cardiovascular events. The contraceptive mechanism of action of combined pills depends fundamentally on their progestin component. METHODS: A narrative review was performed. RESULTS: The drospirenone-only pill, including this synthetic progestogen with antimineralocorticoid and antiandrogenic activity, has high contraceptive efficacy that has been demonstrated with a 24-day schedule of 4-day administration of hormone-free pills. Due to its safety profile, the drospirenone-only pill is suitable even in high-risk populations, such as women with high blood pressure, thromboembolism, smoking or dyslipidemia. CONCLUSION: Considering the increasing prevalence of these comorbidities in Latin America, the 4 mg drospirenone-only pill is suggested as one of the strategies of choice in the region for those women who choose oral contraceptives.
