Measuring potential interest in a postpartum contraceptive vaginal ring among breastfeeding women in India

Access to safe and effective contraception for postpartum women is an important priority in India, where the unmet need for postpartum contraception is high. In this paper, we estimate the potential market size in India for the progesterone vaginal ring (PVR), a novel user-controlled contraceptive method that offers additional contraceptive choice for lactating women. We integrated results of a one-year phase-3 multicenter clinical trial for the PVR conducted in India with an analysis of the National Family Health Survey (2015–16) and 2019 United Nations Population Division data to generate three estimates of potential market size for the PVR among postpartum breastfeeding women in India. We estimate the potential market size for the PVR ranges from a low estimate of 543,262 women to a high estimate of 1.3 million women, with a separate intermediate estimate of 737,460 women. Our analysis indicates the PVR could play an important role in decreasing unmet need among postpartum women in India, thereby reducing risks to mothers and children associated with short birth intervals, helping to prevent unintended pregnancies, and helping to address access-related issues heightened by the COVID-19 pandemic.
