Objective: To evaluate the impact on erectile and ejaculatory function following transrectal ultrasound-guided biopsies of the prostate (TRUS-Bx) in sexually active men. Methods: Monocentric prospective study from May 2021 to January 2022 of consecutive patients with suspected prostate cancer [elevated prostate specific antigen (PSA) level and/or abnormal digital rectal examination] undergoing TRUS-Bx. The 15-item version of the International Index of Erectile Function (IIEF-15), Premature Ejaculation Diagnostic Tool (PDET) and short form of Male Sexual Health Questionnaire (MSHQ-EjD Short Form) were assessed before, one and three months after TRUS-Bx. The primary endpoint was to evaluate the risk of temporary post-biopsy erectile and/or ejaculatory dysfunctions. The statistical significance was set as p value < 0.05. Results: A total of 276 consecutive patients were included in the study. The median age, PSA and biopsy cores were 65 years (IQR 59-69), 7 ng/ml (IQR 5-9.7) and 16 (IQR 12-16), respectively. We compared the IIEF subdomains before TRUS-Bx vs. one or three months: the erectile function (EF) decreased after one month (p
