To investigate the testicular blood flow in patients with testicular microlithiasis (TM) and its correlation with the seminal profile in infertile men.
We selected 88 infertile men and examined them by testicular color Doppler and routine seminal tests.
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.
TM may be one of the causes of poor sperm function in infertile men.
探讨睾丸微结石症（TM）患者的睾丸血流情况及其与不育男性精液指标的相关性。
选取88例不育男性，采用睾丸彩色多普勒及精液常规检查。
19例（19.3%）患者发现睾丸微结石症，其中7例（8.0%）为典型睾丸微结石症（CTM），10例（11.3%）为局限性睾丸微结石症（LTM）。发病年龄、双侧睾丸体积、双侧睾丸动脉阻力指数（RI）、精液量及畸形精子率差异均无统计学意义。CTM组双侧睾丸收缩期峰值流速（PSV）、精子计数及精子活力均显著低于LTM组（P<0.05），而LTM组与无钙化组比较差异无统计学意义。
TM可能是不育男性精子功能不良的原因之一。
