From Birth Control to Menopause: The Science Behind Natural Cycles and the Future of Femtech with Dr. Elina Berglund

From Birth Control to Menopause: The Science Behind Natural Cycles and the Future of Femtech with Dr. Elina Berglund

Dr. Elina Berglund, particle physicist turned femtech pioneer, unpacks how Natural Cycles (code: BIOHACKING) is transforming women’s health through data, wearables, and AI.

Dr. Elina shares how her search for a hormone-free birth control method led to creating the world’s first FDA-cleared digital contraceptive. Today, Natural Cycles is expanding far beyond fertility — into perimenopause, menopause, and even male contraception research.

If you’re a modern, health-curious woman who wants to understand your hormones from your first period to menopause — through science you can actually trust — this episode is your roadmap.
