Bryan Johnson Stores Girlfriend's Menstrual Blood for Longevity Research
Tech entrepreneur Bryan Johnson stores 10 ml of his girlfriend Kate Tolo's menstrual blood at -80°C as part of his longevity research. He explains that menstrual blood offers a non-invasive way to study uterine health, including cells and contaminants like microplastics and endocrine disruptors, which standard blood tests may miss. While some online reactions questioned the practice, fertility experts note that using menstrual blood for health insights is not unusual. Johnson aims to advance understanding of aging and disease through this approach.
