The intratesticular artery resistive index as a predictor of spermatogenesis: A prospective study

Abstract

Introduction:

With the objective to assess the correlation between the resistive index of intratesticular artery as predictor of spermatogenesis this case control study was conducted.

Methods:

A Prospective study conducted during period April 2021 to March 2023. Total 50 patients, with oligoasthenozoospermia taken as cases and other 50 men with normal sperm count taken as controls. History taken & clinical examination, Semen analysis, hormonal evaluation & Color Doppler ultrasonography of scrotum done. Resistive Index of testicular arteries was obtained. Cases and controls were compared.

Results:

The age of the study group ranged between 21 and 40 years. Among the cases maximum patients 23 out of 50 and among controls with maximum number 21 out of 50 patients were belonged to age group 26–30 years.The mean semen volume for the cases & controls was 2.76 ± 0.44 ml and 3.32 ± 0.54 ml respectively. The Mean sperm concentration in the cases & controls was 14.33 million/ml & 84.8 million/ml. Mean Type A sperm motility was 20.82% ± 7.86 in cases and 54.96% ± 5.41 in controls. The mean testicular volume in cases was 18.36 ± 0.75 & in controls was 18.39 ± 0.62 ml. Hormonal evaluation done in both cases and controls and mean value of FSH in cases and controls was 7.57 ± 2.34 and 6.27 ± 3.55 respectively (p-value = 0.036). Mean value of Resistive Index (PSV − EDV)/PSV) in cases and controls were found 0.63 ± 0.32 and 0.53 ± 0.37 respectively (p-value = 0.001).

Conclusion:

The intratesticular artery resistive index can be utilized as valuable predictive marker to indicate spermatogenesis.
