To investigate the effect of native seminal plasma on the recovery of frozen human sperm, various concentrations of seminal plasma (0, 25, 50, 75, and 100%) were used in cryoprotectant for freezing sperm, and the viabilities of frozen-thawed sperm were compared. The post-thaw sperm motility of 50 or 75% seminal plasma in the fertile group was significantly higher than that of 0, 25, or 100%. The post-thaw motility of 75% donor seminal plasma in the patient group was higher than that of other concentrations. It was suggested that a certain concentration of native seminal plasma in cryoprotectant would be helpful to the viability of human sperm cryopreservation.
