摘要：To investigate the correlation of prostatic calculi (PC) with semen parameters in men with fertility intention, this retrospective case-control study enrolled 1,303 participants ranging from 20 to 59 years old; 725 were diagnosed with PC using abdominal ultrasonography. Patients with PC were classified into the type A calculi group (discrete and small echoes) and type B calculi group (coarse and large masses of multiple echoes). Five hundred and seventy-eight men without PC were recruited for the control group. The clinical data of each group were collected and analyzed. The total motility was significantly lower for subjects with type B calculi (41.84% +/- 17.50%) than for subjects in the type A calculi (51.78% +/- 20.84%; p < .001) and control (54.47% +/- 20.74%; p < .001) groups. The percentage of progressively motile was significantly lower for the type B calculi (31.66% +/- 14.68%) group than the type A calculi (40.17% +/- 17.09%; p < .001) and control (41.83% +/- 17.05%; p < .001) groups. The results of the hypo-osmotic swelling test yielded significantly lower percentages in the type B calculi group (59.88% +/- 17.13%) than the type A calculi (65.28 +/- 14.43%; p = .005) and control (66.92 +/- 16.12%; p < .001) groups. The type B calculi group had a significantly higher percentage of round cell concentration than control (4.5% vs. 1.0%; p = .007) did. Small and discrete PC may not influence semen quality among adult men with fertility intention, but larger and coarser PC are associated with decreased sperm motility.
