In vitro prediction tests of fertility of frozen semen of sheep and cattle. Variation in fertility after artificial insemination (AI) of frozen semen is high and leads to economic loss. Routine assessment of the quality of frozen semen relies on crude, simple tests of motility and morphology of sperm. More sophisticated sperm ultrastructural and function tests have recently been developed, but it is not known how these tests relate to fertility in the field. In this project we will test a range of in vitro methods of assessment of motility and morphology of sperm and compare them with fertility of frozen semen samples after AI, leading to more objective methods of semen analysis.

牛、羊冷冻精液生育能力的体外预测试验。冷冻精液人工授精（AI）后的生育能力变化很大，导致经济损失。对冷冻精液质量的常规评估依赖于对精子活力和形态的粗略、简单的测试。最近开发了更复杂的精子超微结构和功能测试，但尚不清楚这些测试与该领域的生育能力之间的关系。在这个项目中，我们将测试一系列体外评估精子活力和形态的方法，并将其与人工智能后冷冻精液样本的生育能力进行比较，从而产生更客观的精液分析方法。
