Safe, affordable period care, delivered to the last mile.

500 million women and girls lack access to safe and affordable period products.

The result: missed school and work, poor health, and silence driven by stigma and taboos.

Introducing the Asan cup

Developed at the Harvard Innovation Lab, the Asan cup is the world's highest quality reusable menstrual cup.

One cup lasts up to 10 years and replaces 2,500 sanitary pads.

Our proven behaviour change model

1. Train-the-Trainer

Asan identifies community ambassadors, including NGO staff, mobilisers, and health workers, and equips them with the knowledge, confidence, and resources to run menstrual health education sessions and train women on safe menstrual cup use.

2. Community Connect

Community connect sessions build trust and awareness around menstrual health and cups. Ambassadors lead these educational sessions and introduce the Asan cup to small groups of women and girls.

3. Education and Distribution

Distribution sessions include a demonstration, practical guidance, and Q&A on the Asan cup. Every participant receives:

  • An Asan menstrual cup
  • A cloth storage pouch
  • A local-language user guide
  • Trainer's contact details for ongoing support

4. Follow Up

3–6 months post-distribution, ambassadors conduct follow-up calls, discussions, and interviews to assess experiences, address concerns, and measure adoption - helping inform program improvements and impact.

90% of women successfully adopt and Asan cup long term.

Stories of Impact

  • Shantibai, community leader, Kanakapura, Karnataka India

    "I immediately recognised the benefits of the Asan cup compared to pads and cloth. It has made such a difference — especially for staying active during my period. Now, through my role in the Gram Panchayat, I'm able to spread the word and encourage all the women and girls in my village to make the switch."

    “This has been one of the best decisions I’ve made for my health. At first, I was unsure, but after a few tries, I can’t imagine going back to disposable pads. The comfort, reliability, and leak-free protection are unmatched. This cup has truly empowered me to take control of my period with confidence and ease."

  • Shalu, 18-year-old student, Lucknow India

    "I feel really comfortable using my Asan cup. It's so much better than using pads — there's no irritation, no worry, and no constant checking. I feel completely tension free and can go about my day, enjoy my life, and stay active during my period without any hassle. I only wish I had discovered it sooner!"
