    Frontline, gold standard treatment for combatting androgenic alopecia

    Studysummary This study found that components derived from Uromedic® pumpkin seeds, especially Δ7-sterols, may inhibit DHT production and AR binding, potentially benefiting prostate and bladder health by moderating these mechanisms.

    The study demonstrated that Uromedic® pumpkin seed-derived Δ7-sterols, extract, and oil effectively inhibited 5α-reductase enzymes and bound to androgen receptors in vitro, with Δ7-sterols showing the strongest binding (IC50 = 0.2 mg/ml). The pumpkin seed oil, soft extract, and Δ7-sterols significantly inhibited 5α-R1 (70%-95%) and moderately inhibited 5α-R2 (25%-50%) compared to finasteride. These findings suggested potential therapeutic benefits for managing conditions like benign prostate hyperplasia by reducing dihydrotestosterone levels and blocking its receptor binding. Further research was needed to confirm these effects in human subjects.
