RESUMO
OBJECTIVE: To investigate the testicular blood flow in patients with testicular microlithiasis (TM) and its correlation with the seminal profile in infertile men. METHODS: We selected 88 infertile men and examined them by testicular color Doppler and routine seminal tests. RESULTS: Testicular microlithiasis was found in 19 (19.3%) of the patients, classic testicular microlithiasis (CTM) in 7 (8.0%), and limited testicular microlithiasis (LTM) in 10 (11.3%). No significant differences were observed in the age of onset, bilateral testicular volume, resistance index (RI) of bilateral testicular arteries, semen amount and the rate of teratospermia. The bilateral testicular peak systolic velocity (PSV), sperm count and sperm motility were significantly lower in the CTM than in the LTM group (P < 0.05), but showed no statistically significant difference between the LTM and the non-calcification group. CONCLUSION: TM may be one of the causes of poor sperm function in infertile men.
