Role of color Doppler ultrasonographic parameter as a predictor of spermatogenesis and infertility

Abstract

Abstract

Introduction:Androgens target the testicular arteries, which may be aberrant in men who are infertile. One of the fastest and most accurate ways to measure testicular blood flow is by color doppler ultrasonography (CDUS), which combines anatomical and velocity data. The aim of this research is to determine whether testicular artery end diastolic velocity (EDV), peak systolic velocity (PSV), and resistive index (RI) can be used to differentiate between variuos types of dyspermia.

Materials and Methods: This was a prospective observational study. In totalninety patients were enrolled in the study which includes twenty-seven patients with non-obstructive azoospermia (NOA), nineteen patients with oligospermia (OL), twenty four with obstructive azoospermia (OA), andtwenty in control group having normal sperm count and recent paternity. We compared variables like end diastolic velocity, peak systolic velocity, resistive index, bilateral testicular volume, testosterone, and follicular stimulating hormone among different dyspermic group with control group.

Results: the mean age of the study participants was 31.5 years. PSV and RI in the NOA and OL groups significantly lower compared to control groups while OA group was comparable with control group. With respect to EDV, we observed a significantly lower value only in NOA group compared to control group. Significantly lower mean testicular volume and higher FSH levels were observed in NOA group.

Conclusion:Investigating male infertility can be challenging but color doppler ultrasound might be a very helpful.When used routinely in clinical settings, the RI and PSV can be trustworthy markers for identifying infertility or dysspermic males especially distinguishing between obstructive and unobstructive azoospermia.
