Objectives This study is to understand the difference of semen quality among the differenc are-as and the ralated factors. Methods The semen samples come from Shenzhen,Chendu,Zunyi,Spain. The param-eters such as semen density,viability ,grade a + b motility were compared. Results The semen quality in Shenz-hen and Chengdu were compared, parameters such as semen density,viability,grade a + b motility were significant diference (p <0.01) ; The semen quality in Shenzhen and Zunyi ware compared, parameters such as semen densi-ty,viability,grade a + b motility were significant difereace (p <0.01). The semen quality in Shenzhen and Spain was compared, parameters such as semen volume ,semen density,total semen ,viability ,grade a + b motility have not significant dicline.
