Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Pumpkin seeds, particularly their oil, have been traditionally used in various cultures to support prostate health, but there is also a growing body of scientific evidence that supports this use. Several clinical studies and reviews suggest that pumpkin seed oil may benefit men with benign prostatic hyperplasia (BPH), a common condition characterized by prostate enlargement. The seeds contain phytosterols and other bioactive compounds that may inhibit the activity of 5-alpha-reductase, an enzyme involved in the conversion of testosterone to dihydrotestosterone (DHT), a hormone implicated in prostate growth.

A randomized, double-blind, placebo-controlled study published in the journal Urology (2009) showed that men with BPH who supplemented with pumpkin seed oil experienced significant improvement in symptoms, such as urinary flow and frequency, compared to placebo. A review in the journal Andrologia (2014) also found supportive evidence for the use of pumpkin seed oil in improving BPH symptoms, though the authors noted that more large-scale studies are needed.

However, while the data are promising, they are not as robust or extensive as those for pharmaceutical treatments. Therefore, the evidence level is rated as 3 out of 5—indicating moderate scientific support, with some limitations in study size and methodology. In summary, pumpkin seed oil shows potential as a supportive natural ingredient for prostate health, especially in the context of mild to moderate BPH symptoms.
