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.
为研究天然精浆对冷冻人类精子复苏的影响，在冷冻精子的冷冻保护剂中使用了不同浓度的精浆（0%、25%、50%、75%和100%），并比较了冻融后精子的活力。在生育组中，50%或75%精浆组冻融后精子活力显著高于0%、25%或100%精浆组。在患者组中，75%供体精浆组冻融后活力高于其他浓度组。提示冷冻保护剂中一定浓度的天然精浆有助于人类精子冷冻保存的活力。
