Objectives: To understand sperm motility in adults and its association with lifestyle in an ethnic minority area in Southwest China. <span lang="EN-US" style="white-space:normal;" "="">Methods: A hospital-based cross-sectional study to assess sperm motility in male adults was conducted at the Reproductive Health Center from January 2018 to May 2019. <span lang="EN-US" style="white-space:normal;" "="">The <span lang="EN-US" style="white-space:normal;" "="">dat<span lang="EN-US" style="white-space:normal;" "="">a<span lang="EN-US" style="white-space:normal;" "=""> was collected with a questionnaire and semen quality was analyzed with Computer-Aided Sperm Analysis system (CASA).
