Abstract
The present study aimed to show epididymal sonographic findings in infertile males with isolated asthenozoospermia as well as their correlation with seminal plasma l-carnitine. Eighty married men were recruited in the study. Fifty infertile men with isolated asthenozoospermia and 30 fertile controls with normal semen parameters were included. Semen analysis was done with estimation of seminal plasma l-carnitine level. Scrotal ultrasonography was used as the diagnostic method for assessing epididymal morphology. Epididymal heterogeneous echogenicity was significantly higher in the infertile group compared to the controls. Whereas homogeneous epididymal echotexture and seminal plasma l-carnitine levels were significantly higher in the controls compared to the infertile patients. Interestingly, it was observed that within each group, seminal l-carnitine and sperm total motility were significantly higher in those with homogeneous rather than heterogeneous epididymal echotexture. Our study demonstrated a significant association between epididymal echo-texture, seminal plasma l-carnitine and sperm motility. Thus, we recommend performing epididymal sonographic evaluation as one of the basic investigations for infertile men.
