摘要
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，讨论了男性受精组成对子宫反应和妊娠率的影响。授精可能因体积，精子浓度，总精子数量，存在，不存在或精浆比例和体质组成而不同。精液可以用作新鲜，冷却或冷冻。精液沉积的部位也起作用;使用宫腔镜或经直肠引导技术将精液沉积到子宫体内（标准人工授精（AI））或同卵巢前卵泡（深AI）的子宫角尖端。除了妊娠率之外，还考虑子宫对子宫收缩的反应，包括子宫肌层收缩，精子的转运和消除以及子宫炎症，子宫内膜炎症反映为多形核白细胞的数量，酶水平和子宫内液的存在。生殖正常和异常的母马进行比较。
