Abstract

Biochemical and physical changes during the cryopreservation process adversely affect sperm function required for fertilization. Recently, many studies have been conducted to find effective pre-freezing treatments to limit these damages. The present study aimed to investigate the effects of pre-freezing treatment with quercetin and crocin, individually or in combination, on sperm parameters after thawing procedure. For this, semen samples from 20 normozoospermic men were collected and then each sample was divided into five equal parts: 1. fresh group 2. frozen-thawed group without addition of antioxidants 3. frozen-thawed group containing 1 mM crocin, 4. frozen-thawed group containing 50 μM quercetin, and 5. frozen-thawed group containing a combination of 1 mM crocin and 50 μM quercetin. Pre-cryopreservation and post-thaw sperm motility, morphology, viability, DNA fragmentation, reactive oxygen species [1] (ROS) levels, and mitochondrial membrane potential [2] (MMP) were investigated. Cryopreservation significantly reduced sperm quality. Both crocin and quercetin individually improved sperm progressive motility, decreased ROS levels, reduced DNA fragmentation, and marginally increased MMP, though crocin seems to be more successful in protecting sperm quality. More interestingly, the combined addition of crocin and quercetin to the sperm-freezing medium did not show positive effects on sperm quality. Crocin and quercetin may play a role in mitigating the cryopreservation-induced injury to sperm.

冷冻保存培养基中添加番红花苷和槲皮素对解冻后人类精子质量的影响。

冷冻保存过程中的生化和物理变化会对受精所需的精子功能产生不利影响。最近，已经进行了许多研究来寻找有效的冷冻前处理来限制这些损伤。本研究旨在研究槲皮素和番红花素单独或联合冷冻处理对解冻后精子参数的影响。为此，收集了20名精子正常男性的精液样本，然后将每个样本分为五等分：1。新鲜组2。不添加抗氧化剂的冻融组3。含有1mM番红花苷的冷冻-解冻组4。冻融组含槲皮素50μM。冷冻-解冻组，含有1mM番红花苷和50μM槲皮素的组合。研究了冷冻保存前和解冻后精子的活力、形态、活力、DNA断裂、活性氧[1]（ROS）水平和线粒体膜电位[2]（MMP）。冷冻保存显著降低精子质量。番红花苷和槲皮素分别改善了精子的进行性运动，降低了ROS水平，减少了DNA断裂，并略微增加了MMP，尽管番红花苷似乎在保护精子质量方面更成功。更有趣的是，在精子冷冻培养基中联合添加番红花苷和槲皮素并没有对精子质量产生积极影响。Crocin和槲皮素可能在减轻冷冻保存对精子的损伤中发挥作用。

期刊介绍： Cell and Tissue Banking provides a forum for disseminating information to scientists and clinicians involved in the banking and transplantation of cells and tissues. Cell and Tissue Banking is an international, peer-reviewed journal that publishes original papers in the following areas: basic research concerning general aspects of tissue banking such as quality assurance and control of banked cells/tissues, effects of preservation and sterilisation methods on cells/tissues, biotechnology, etc.; clinical applications of banked cells/tissues; standards of practice in procurement, processing, storage and distribution of cells/tissues; ethical issues; medico-legal issues.
