Founded in 2019 and a Y Combinator graduate, adyn raised $2.65 million in seed funding co-led by Lux Capital and M13, with the Birth Control Optimization Test positioned as the first biology-based test for contraceptive personalization. adyn's Birth Control Optimization Test analyzes blood samples for hormone profiles and genetic variants associated with specific contraceptive side effect risks (blood clot risk with estrogen-containing methods, mood effects from synthetic progestins, breakthrough bleeding patterns) and matches results to contraceptive options that the individual's biology is likely to tolerate well. The test translates complex pharmacogenomic and endocrinology research into actionable recommendations that gynecologists and patients can use together to make evidence-based contraceptive decisions. In 2025, adyn operates in the women's health testing and femtech market with Mira (hormone monitoring), Modern Fertility (now part of Ro), and telemedicine birth control platforms (Nurx, The Pill Club) for personalized hormonal contraceptive guidance. Contraceptive personalization represents an underserved opportunity — despite 100+ million people using hormonal birth control globally, the selection process remains largely empirical (try it, see how you feel, switch if side effects are intolerable). Lux Capital's investment signals deep biotech conviction about the precision medicine angle in reproductive health. The 2025 strategy focuses on direct-to-consumer sales of the test kit, building clinical partnerships with OBGYNs and reproductive endocrinologists, and expanding the test panel to include additional genetic variants relevant to contraceptive outcomes. ## Frequently Asked Questions ### What is adyn?
