%X ABSTRACT Objective: To study scrotal ultrasonographic characteristics in patients with subclinical varicocele (SV) and investigate their relationship with semen parameters. Patients and methods: In all, 56 men with SV were recruited and divided into two groups, according to their semen characteristics. Group A, comprised 34 men with normal semen analysis; and Group B, comprised 22 men who carried at least one abnormality, regarding sperm concentration, motility and morphology. Between the two groups we compared: age; body mass index (BMI); semen pH and semen volume; total testicular volume (TTV); maximal vein diameter (MVD) and degree of reflux; mean values of peak-systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) of the intratesticular arteries; whether bilateral SV; and serum testosterone and follicle-stimulating hormone (FSH) levels. Results: Asthenospermia was present in all patients in Group B; 10 patients had asthenospermia only, six patients were astheno-oligospermic and six patients had astheno-oligo-teratospermia. Age, BMI, semen pH and volume, TTV, MVD and degree of reflux did not differ significantly between the two groups (P > 0.05). However, EDV, PSV and RI were significantly different (P < 0.05). Bilateral SV was significantly more frequent in patients in Group B (P < 0.05). Finally, FSH was elevated in Group B (P < 0.05), whereas testosterone was normal in both groups, albeit significantly lower in men with abnormal semen analyses (P < 0.05). Conclusion: Classic ultrasonographic characteristics in men with SV, such as venous size or degree of reflux, were insufficient to distinguish patients with abnormal semen analysis. However, bilateral disease and intratesticular haemodynamics differed significantly in patients with SV and abnormal semen analysis.
