Proov Complete Fertility Testing System

The Proov Complete Fertility Testing System is a multi-hormone diagnostic platform designed to provide a holistic view of the menstrual cycle, moving beyond simple surge prediction to include ovulation confirmation. The system utilizes lateral flow assays to track four critical biomarkers: Follicle-Stimulating Hormone (FSH) to assess follicle recruitment, Estrone-3-Glucuronide (E1G) to identify the opening of the fertile window, Luteinizing Hormone (LH) to detect the peak surge, and Pregnanediol Glucuronide (PdG) to confirm that an egg was successfully released. A primary differentiator of Proov is its focus on the 'Progesterone Score,' which evaluates PdG levels during the critical implantation window. Clinical evaluation, including a study on ClinicalTrials.gov (NCT03924440), supports the system's ability to identify luteal phase deficiencies that standard LH-only tests miss. While the tests are qualitative strips, the Proov Insight app uses AI-driven optical scanning to interpret results and provide quantitative-style insights. This makes the system an invaluable resource for users with PCOS, endometriosis, or those over 35 who want to ensure their cycles are anovulatory and healthy.
