Sexual safety and efficacy of a pollen extract and teupolioside-based supplement in men with benign prostatic hyperplasia: a prospective observational study
Abstract
BACKGROUND
Benign prostatic hyperplasia (BPH) is a common age-related condition that often results in lower urinary tract symptoms (LUTS), reduced quality of life, and sexual dysfunction. Conventional pharmacotherapies, while effective, are frequently associated with adverse effects on sexual and ejaculatory function. This study evaluated the sexual safety and clinical efficacy of a dietary supplement containing pollen extract and teupolioside, in men with BPH.
METHODS
In this prospective, single-arm observational study, 25 men with moderate LUTS due to BPH received daily pollen extract and teupolioside supplementation for 90 days. The primary endpoints were sexual function (International Index of Erectile Function, IIEF-5), ejaculatory function (Male Sexual Health Questionnaire-Ejaculatory Dysfunction, MSHQ-EjD), quality of life (IPSS-QoL), and patient global impression of improvement (PGI-I). Secondary endpoints included changes in urinary flow (Qmax) and LUTS severity (International Prostate Symptom Score, IPSS). Assessments were conducted at baseline, 1 month, and 3 months.
RESULTS
Sexual and ejaculatory functions remained stable over the treatment period, with no statistically significant deterioration observed. QoL improved significantly by the 3-month mark (IPSS-QoL median score reduced from 3 to 2; p<0.008), and PGI-I scores reflected high patient satisfaction (median 2, IQR 1). Qmax significantly increased from 12.4 mL/s at baseline to 15.5 mL/s at 3 months…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 25 participants or records.
