  • Title: Transrectal ultrasonography of infertile men.
    Author: Jarow JP.
    Journal: Fertil Steril; 1993 Dec; 60(6):1035-9. PubMed ID: 8243682.
    Abstract:
    OBJECTIVE: To determine normal transrectal ultrasonographic anatomy in young men and the frequency of abnormalities in the infertile population. DESIGN: Transrectal ultrasonography was performed upon 30 fertile volunteers and 150 consecutive men referred for male factor infertility. SETTING: A male fertility center. RESULTS: Transrectal ultrasonography was normal in 60% of controls and 53% of infertile group. The frequency of hyperechoic lesions within the prostate was similar in controls (40%) and infertile men (39%). Müllerian duct cysts were present in 11% of the infertile men and none of the volunteers. Rectal exam was normal in all of the men. CONCLUSIONS: Transrectal ultrasonography is more sensitive at detecting abnormalities of the seminal vesicles and prostate than rectal exam. Hyperechoic lesions within the prostate is frequently a normal finding. Müllerian duct cysts are more frequently observed in infertile men and may be a cause of ejaculatory duct obstruction.
