dc.description.abstractIntroduction: The primary objective of this investigation is to explore the impact of ejaculation on urinary flow rates in men experiencing lower urinary tract symptoms. Materials and Methods: This study involved the enrollment of 55 male patients who presented with lower urinary tract symptoms. An assessment encompassed components, including medical history, questionnaires related to sexual activity and lower urinary tract symptoms, bladder diary, physical examination, urinalysis, urine culture, ultrasound examination and measurements of serum prostate-specific antigen, free flow uroflowmetry, and post-void residual urine volume. All participants were instructed to abstain from ejaculation for 3 days before undergoing uroflowmetry (UF1). Subsequently, they were required to ejaculate. Subsequent uroflowmetry assessments were conducted at 2 to 4 h (UF2) and 48 to 50 h (UF3) after ejaculation. No further ejaculations were permitted during this timeframe. Results: The patients had a mean age of 50.97 ± 1.47 years. Statistically significant differences were observed in the mean values of Qmax and corrected Qmax (cQmax) between UF1 and UF2 measurements (p < 0.05). These differences were only in patients with benign prostatic enlargement (BPE) (p < 0.05). Furthermore, the number of patients with Qmax <15 mL/s showed a statistically significant difference between UF1 and UF2 measurements, specifically in the BPE group (p = 0.016). Conclusions: In this study, we have observed a significant and temporary increase in the Qmax following ejaculation, particularly among patients with BPE. This indicates that ejaculation can potentially complicate the interpretation of uroflowmetry results. Therefore, further research is necessary to gain a more comprehensive understanding of this phenomenon. © 2024 Wiley Periodicals LLC.en_US
