Abstract
OBJECTIVE: Scrotal ultrasound is not a routine investigation in the clinical approach to male infertility analysis. This study aims to identify the role of testicular Doppler ultrasound in male infertility assessment and its relation to semen parameters in non-azoospermic men. METHODS: Cross-sectional descriptive analysis of 558 men from infertile couples were examined at the Hue Center for Reproductive Endocrinology and Infertility, Hue University Hospital from June 2016 to May 2018. Some cohort characteristics, semen analysis and testicular Doppler ultrasound were analyzed. Men with acute systemic diseases, acute urinary tract infection, hepatic dysfunction, malignant diseases, retrograde ejaculation, cryptorchidism or azoospermia were excluded. RESULTS: The mean volumes of the right and left testicles were 8.87 and 8.77 ml, respectively. The total volume of the 2 sides was 17.63 ± 4.34 ml (95% confidence interval 17.27-18.00 ml). The mean right resistive index (RI) was 0.61 ± 0.23, and the mean left RI was 0.59 ± 0.01. The rate of normal semen quality was 23.2% in group with varicocele and 30.6% in group with non-varicocele. The ultrasound results from the normal semen group were much different from those of the abnormal semen group regarding testicular volume: mean right testis volume: 9.67 ± 1.88 vs. 8.75 ± 2.34 ml, p = 0.0096; mean left testis volume: 9.54 ± 1.78 vs. 8.51 ± 2.44 ml, p = 0.0047; mean total volume of 2 sides: 19.21 ± 3.60 vs. 17.26 ± 4.59 ml, p = 0.005 (varicocele group); mean right testis volume: 9.21 ± 2.21 vs. 8.63 ± 2.21 ml, p = 0.029 (non-varicocele group). The other indexes of color Doppler ultrasound (peak systolic velocity, end diastolic velocity, RI) were not found to correlate with semen quality. CONCLUSIONS: Testicular volume which has a close relation to the semen parameters could be used as a clinical prediction factor for the quality of semen.
