Pumpkin Seed Oil for Prostate Health

Research suggests that pumpkin seed oil and related extracts may offer modest benefits for prostate-related urinary symptoms, though the current evidence base is limited in both size and rigor. A small single-arm pilot randomized controlled trial found that an oil-free pumpkin seed extract was associated with reduced urinary symptom scores and improved quality of life in men with benign prostatic hyperplasia, while a separate controlled study reported that topically delivered pumpkin seed oil improved urinary flow, inflammation markers, and symptom scores in men with chronic nonbacterial prostatitis compared to placebo. Studies indicate a generally supportive direction across these findings, but significant limitations apply, including small sample sizes, lack of placebo controls in some trials, and the use of different pumpkin seed preparations and delivery methods that make direct comparisons difficult. A third study focused on niosome-based skin delivery systems for the oil and did not directly assess prostate outcomes, underscoring that much of the research remains preliminary and that further well-designed clinical trials are needed before firm conclusions can be drawn.
