Efficacy of flower pollen extract with vitamins in improving urinary and sexual function in patients with chronic prostatitis: a retrospective study

Objectives: To assess the efficacy and safety of Flower Pollen Extract with Vitamins (PEV) in improving urinary and sexual function in men diagnosed with chronic prostatitis (CP). Methods: A retrospective controlled study was conducted involving 145 men with CP. Participants were divided into two groups: the intervention group received PEV (n=71) and the control group received ibuprofen (n=74). Clinical and functional outcomes were evaluated at baseline and at 1, 3, and 12 months post-treatment. Results: Both groups exhibited comparable baseline characteristics. At 3 months, the PEV group demonstrated significantly greater improvement in IPSS (9.4 ± 2.7 vs. 10.3 ± 2.6, p=0.04), NIH-CPSI (11.5 ± 3.7 vs. 13.6 ± 4.2, p=0.002), and IIEF-5 (19.8 ± 3.6 vs. 17.7 ± 3.3, p<0.001). These benefits were maintained and further enhanced at 12 months, with mean IPSS 7.6 ± 2.1, NIH-CPSI 6.5 ± 2.4, and IIEF-5 21.6 ± 3.3 in the PEV group (all p<0.005). No significant differences were observed in Qmax. Conclusions: Long-term PEV therapy significantly improves urinary and sexual function in men with CP compared with ibuprofen treatment, demonstrating sustained, time-dependent efficacy and excellent safety.
