Effects of various concentrations of native seminal plasma in cryoprotectant on viability of human sperm.
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.
