Why This Biomarker Matters

Progesterone levels confirm ovulation and assess fertility. Abnormal levels indicate hormonal imbalances, anovulation, or pregnancy-related concerns requiring medical evaluation.

Overview

Progesterone is a hormone produced by the ovaries after ovulation and by the placenta during pregnancy. A urine progesterone test measures metabolites of this hormone to assess reproductive function and confirm ovulation. Abnormally low levels may indicate anovulation (failure to ovulate), luteal phase defect, or hormonal imbalances affecting fertility. This test helps evaluate menstrual irregularities, assess fertility, and monitor pregnancy status. It's particularly useful for tracking ovulation timing and identifying hormonal causes of infertility.
