Abstract Objective To analyze the semen quality parameters of sperm donor volunteers, so as to provide insights into male infertility control and related research. Methods A total of 155 sperm donors were recruited from the Human Sperm Bank of Zhejiang Province using the convenience sampling method from January to March 2021. Demographic information were collected through questionnaire surveys. Semen were collected, and parameters including semen volume, sperm concentration, total number of sperm, forward motility rate and total sperm viability were measured. Semen quality was evaluated according to the WHO Laboratory Manual for the Examination and Processing of Human Semen. Results Among 155 sperm donors, 127 were unmarried (81.94%), 97 were unemployed (62.58%), 91 had a bachelor's degree and above (58.71%), and 42 had a body mass index of 25 kg/m2 and above (27.09%). The median age was 24 (interquartile range, 7) years. The median (interquartile range) abstinence time, total number of sperm, semen volume, sperm concentration, forward motility rate and total sperm viability were 4 (1) d, 51 (38) ×106/1 ejaculation, 3.90 (2.20) mL, 204.60 (161.30) ×106/mL, 47% (10%) and 50% (11%), and the unqualified rates were 0%, 0.65%, 1.29%, 4.52%, 9.68% and 18.06%, respectively. The overall unqualified rates of semen quality was 20.65%. Conclusion There were 20.65% of the 155 sperm donors with unqualified semen, and the unqualified rates of forward motility rate and total sperm viability were relatively high.
