Cervical mucus may hold key to unexplained infertility
NCT ID NCT06771401
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to better understand cervical mucus and find biological markers that could help diagnose or predict reproductive problems like infertility. Researchers will use infrared spectroscopy to analyze mucus samples from 24 women—some healthy and some with unexplained infertility—over their menstrual cycles. The goal is to identify differences that could lead to better tests or treatments in the future.
