冷冻保存配子,结合人工授精,是支持濒危和受威胁物种保护计划的基本选择。大约三分之二的猫科动物被归类为“濒临威胁”、“脆弱”或“濒危”(www.cites.org),而且大多数情况下,附睾精是从安乐死或去势的雄性猫科动物身上收集并冷冻保存的。然而,如果在猫科动物中应用非手术阴道人工授精,那么附睾与射精和冷冻保存的精子相比,与新鲜精子相比,其受精潜力有限。附睾液和冷冻精子中精液的缺失或高度稀释,以及延长剂成分对女性生殖道中精子自然相互作用特性的潜在干扰,是除了冷冻猫精子的有限寿命外,阻碍精子正常传递和受精的潜在缺陷。精液中的个别成分以及冷冻扩充剂可能会对精子特性产生不利影响,并对受精率和保存成功率产生不同的影响。对有益成分和有害成分的鉴定和研究是推断改进猫科动物冷冻保存过程的选择的先决条件,特别是如果只有附睾精子可用的话。
Cryobanking of gametes in combination with artificial insemination is an essential option to support conservation programmes for endangered and threatened species. About two‐thirds of the felid species are classified as ‘near threatened’, ‘vulnerable’ or ‘endangered’ (www.cites.org), and mostly, epididymal sperm are collected from euthanized or castrated male felids and cryopreserved. However, epididymal compared with ejaculated and cryopreserved compared with fresh sperm have a limited potential to fertilize if vaginal non‐surgical insemination is applied in feline species. Missing or highly diluted seminal fluid in epididymal and cryopreserved sperm, as well as a potential interference of extender ingredients with the natural interactive properties of sperm in the female genital tract is discussed as potential drawback which hampers a proper sperm transit and fertilization besides the limited longevity of cryopreserved feline sperm. Individual components in seminal fluid as well as cryoextenders may adversely alter sperm properties and have a different impact on fertility and preservation success. The identification and investigation of beneficial as well as detrimental components is a precondition to deduce options for improving the process of cryopreservation in felids, particularly, if only epididymal sperm are available.
