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% \u00b1 17.50%) than for subjects in the type A calculi (51.78% \u00b1 20.84%; p &lt; .001) and control (54.47% \u00b1 20.74%; p &lt; .001) groups. The percentage of progressively motile was significantly lower for the type B calculi (31.66% \u00b1 14.68%) group than the type A calculi (40.17% \u00b1 17.09%; p &lt; .001) and control (41.83% \u00b1 17.05%; p &lt; .001) groups. The results of the hypo-osmotic swelling test yielded significantly lower percentages in the type B calculi group (59.88% \u00b1 17.13%) than the type A calculi (65.28 \u00b1 14.43%; p = .005) and control (66.92 \u00b1 16.12%; p &lt; .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.<\/jats:p>","DOI":"10.1177\/1557988319852018","type":"journal-article","created":{"date-parts":[[2019,5,18]],"date-time":"2019-05-18T06:36:28Z","timestamp":1558161388000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Clinical Correlation of Prostatic Calculi With Semen Parameters in Adult Men With Fertility Intention"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6786-0310","authenticated-orcid":false,"given":"Tong","family":"Chen","sequence":"first","affiliation":[{"name":"Center for Reproductive Medicine, Shandong University, National Research Center for Assisted Reproductive Technology and Reproductive Genetics, The Key Laboratory for Reproductive Endocrinology of Ministry of Education, Jinan, Shandong, P.R.
