Who could benefit from this research

Could help

Women aged 21 and older who use combined oral contraceptives and are willing to contribute samples and medical information.

Less likely to help

Women who do not use COCPs or who decline participation would not benefit from this study.

What this research studies

Researchers at Yale will build a biobank of 700 COCP users to explore how genetics influence drug levels, effectiveness, and safety. The study aims to connect genetic data with real-world responses to combined estrogen-progestin pills, using new phenotypes tailored to steroid hormone medications. By identifying genetic factors that explain variation in drug handling, the team hopes to improve guidance on dosing and safety for women who rely on COCPs.

Why it matters

Potential benefit: If successful, the findings could lead to more personalized COCP choices and safer, more effective contraception for women.

How similar studies have gone: Previous pharmacogenomic work has shown genotype-guided dosing for some drugs, but this project addresses a gap in hormones and contraceptives with a new biobank.
