Impact of duloxetine on male fertility: A randomised controlled clinical trial
This study assessed the impact of duloxetine (serotonin and norepinephrine reuptake inhibitor) on semen parameters, sperm DNA fragmentation and serum hormones. We performed a double-blind, placebo-controlled, randomised clinical trial of duloxetine 60mg or placebo daily for 6 weeks (5 weeks full dose and 1 week taper). Duloxetine was not associated with an increase in the proportion of participants with abnormal sperm DNA fragmentation terminal deoxynucleotidyl transferase dUTP nick-end labelling scores (>25%) on treatment (p = 0.09) or after treatment (p = 0.56), nor did median sperm DNA fragmentation increase on treatment. Compared with placebo, there were no changes in bulk semen parameters during treatment. Limited changes in hormonal values were detected.
Note - A six weak test would be a short-term study and may not indicate any long-term effect.
