Four-hormone cycle tracker reveals ovulation, egg reserve, and progesterone support in one kit

Proov's at-home system measures FSH, E1G (estrogen metabolite), LH, and PdG (progesterone metabolite) across your full cycle via first-morning urine—20 test strips total, results in your phone within 10 minutes. Clinically validated; studies link optimal PdG levels to 75% higher pregnancy rates. Includes personalized testing schedule, Proov Insight app analysis, and 24/7 fertility expert chat.

Evidence

4/5

FSH measurement is a well-established clinical tool with decades of observational evidence supporting its utility in assessing reproductive health, ovarian reserve, and menopausal status. RCTs on FSH-guided interventions exist (e.g., fertility treatment protocols), and FSH thresholds are validated across large cohorts for predicting ovarian reserve and menopause timing. The evidence base is robust for diagnostic and prognostic use.

Mechanism

Follicle-stimulating hormone (FSH) is a gonadotropin produced by the anterior pituitary that regulates reproductive function—stimulating follicle development and estrogen production in females, and spermatogenesis in males. FSH levels reflect ovarian or testicular reserve and can indicate menopause, hypogonadism, or fertility status.
