Background: Menstrual hygiene remains a vital yet often overlooked aspect of women’s health, particularly in resource-limited settings where cost, access, and sustainability pose significant challenges. Menstrual cups offer a reusable, eco-friendly, and cost-effective alternative, but their adoption in India is hindered by social, cultural, and practical concerns.

Methods: This prospective observational study was conducted at a tertiary care center in Chennai from September 2022 to April 2024. A total of 200 first-time menstrual cup users were enrolled following education on proper use. Participants were followed for three consecutive menstrual cycles. Data on demographics, menstrual history, and experiences were collected using pre-tested questionnaires and Likert scales. Statistical analysis was performed using SPSS version 22.

Results: Of 434 women initially surveyed, 200 completed the study. Most were aged 21–30 years (51%), married (57%), and graduates (46%). At baseline, 82.5% used sanitary napkins, with common issues being leakage (41%) and rashes (34.5%). Across three cycles, ease of insertion improved from 72% to 85%, removal from 72% to 82%, and comfort from 90% to 98%. Leakage decreased from 17% to 5%. By the third cycle, 96.5% intended to continue use, and 96% would recommend it to others.

Conclusions: Menstrual cups demonstrated high feasibility and acceptability, with progressive improvement in comfort and reduced leakage. Educational initiatives could play a key role in increasing adoption, offering a sustainable and effective solution for menstrual hygiene management.
