The Intrauterine Devices segmentation by application distinguishes three primary uses: contraceptive, therapeutic, and research. The contraceptive application dominates the market, accounting for roughly 85 % of total revenue, because IUDs provide long‑term, reversible birth control with high efficacy and low failure rates, driving sustained demand across both developed and emerging economies. The therapeutic segment, representing about 10 % of sales, includes devices approved for managing heavy menstrual bleeding, endometrial hyperplasia, and certain gynecologic cancers; its growth is linked to expanding clinical guidelines that favor minimally invasive, device‑based interventions over pharmaceutical regimens. The research application, while modest at 5 %, captures sales to academic and pharmaceutical institutions conducting clinical trials on novel IUD formulations or delivery mechanisms, thereby influencing future pipeline development. Collectively, these application categories shape the overall market size by allocating capital, R&D focus, and distribution channels according to distinct clinical and commercial priorities.
