PRP在供体精液冷冻保存期间的影响 (PRP)
富血小板血浆(PRP)对供体精液在冷冻保存期间质量的影响
精子冷冻保存技术能够在长时间内保持精子的生物学功能,以便后续用于辅助生殖技术(ART)。然而,冷冻和解冻过程会对精子造成结构和功能上的损伤,导致精子活力和活性下降,质膜完整性丧失,甚至DNA损伤。
近年来,研究人员探索了多种策略来保护精子免受冷冻损伤,包括优化冷冻流程、设计冷冻设备以及改进冷冻培养基。
一种可能减轻精子冷冻损伤的措施是在冷冻培养基中添加PRP,即富血小板血浆。先前的研究表明,PRP成分对精液质量有积极影响,能够改善冷冻保存后精子的活力、存活率和质膜完整性。鉴于这些积极结果,本研究将评估将PRP加入精子冷冻培养基的可能性,以及其对患者和临床结果的潜在未来益处。为此,在完成初步精液分析后,每个精液样本将被分装,并根据所属精子组别在冷冻培养基中添加0%、1%、2%和5%的PRP。冷冻保存后将进行精液分析,以评估多项精液质量参数,包括精子计数、活力、形态、活性和染色质分散度。数据需通过统计分析处理,以获得能够主要确定在添加PRP的冷冻保存过程中,精子活力和精子质量是否得到有益改善的结果。

详细说明
本研究的主要目的是检测对照组与使用5%自体PRP冷冻保存样本之间在渐进性运动能力方面是否存在显著差异。
次要目标如下:
检测对照组与使用1%或2%自体PRP冷冻保存样本之间在渐进性运动能力方面的显著差异;根据冷冻保存中使用的PRP分类浓度确定精液质量参数值是否存在显著差异;确定PRP数值浓度与精液质量参数之间是否存在相关性;检查血小板计数(即自体血浆中血小板浓度,其血小板浓度高于原始样本)是否与解冻后分析的精液参数相关。
