In this review, effects of the composition of the inseminate on uterine response and pregnancy rates in mares are discussed. The inseminate can differ for volume, sperm concentration, total sperm numbers, presence, absence, or proportion of seminal plasma, and extender composition. Semen can be used as fresh, cooled, or frozen. The site of semen deposition also plays a role; semen is deposited either into the uterine body (standard artificial insemination (AI)) or into the tip of the uterine horn ipsilateral to the preovulatory follicle (deep AI) using the hysterocopical or transrectally guided techniques. In addition to pregnancy rates, some uterine responses to the inseminate are considered including myometrial contractions, transport and elimination of sperm, and uterine inflammation, which is reflected as numbers of polymorphonuclear leukocytes, enzyme levels, and presence of intrauterine fluid. Reproductively normal and abnormal mares are compared.
在这篇综述中，讨论了输精剂的组成对母马子宫反应和妊娠率的影响。输精剂在体积、精子浓度、精子总数、精浆的存在与否或比例以及稀释剂组成方面可能存在差异。精液可以新鲜使用、冷藏或冷冻。精液沉积部位也起作用；使用子宫镜或经直肠引导技术，精液可沉积于子宫体（标准人工授精（AI））或排卵前卵泡同侧的子宫角尖端（深部AI）。除了妊娠率外，还考虑了子宫对输精剂的一些反应，包括子宫肌层收缩、精子的运输和清除以及子宫炎症，子宫炎症表现为多形核白细胞数量、酶水平和子宫内液体的存在。对生殖正常和异常的母马进行了比较。
