Objectives To assess the impact of transrectal versus transperineal prostate biopsy on erectile function. Methods This was a single‐center, observational, prospective study of consecutive patients who underwent a prostate biopsy (transrectal or transperineal/fusion biopsy). Study participants completed the International Index of Erectile Function‐5 questionnaire before the procedure, and 3 and 6 months after. Prostatic biopsies were carried out following the standard procedure for both techniques. Results The study included 135 male patients with a mean age of 63.5 years. At baseline, 28 patients (21%) presented normal erectile function, whereas 107 patients (82%) presented erectile dysfunction, which was severe in four (3%), moderate in 49 (36%) and mild in 54 (40%), with an overall mean International Index of Erectile Function‐5 score of 17.70. After 3 months, the rates were 29%, 3%, 27% and 38%, respectively (mean International Index of Erectile Function‐5 score 17.95). At 6 months, the rates were 30%, 6%, 28% and 34%, respectively (mean International Index of Erectile Function‐5 score of 17.77). No significant differences between pre‐ and post‐biopsy International Index of Erectile Function‐5 scores at 3 and 6 months were observed, even when analyzing transrectal and transperineal separately. The number of biopsy cores and number of previous biopsies did not influence the International Index of Erectile Function‐5 scores. Conclusions Our findings suggest that prostate biopsy technique, number of biopsy cores and history of previous biopsy do not significantly impact erectile function in the medium term up to 6 months.
