Understanding the molecular basis for sperm function: the sperm connecting piece and sperm motility

精子是将父亲的遗传信息传递给卵母细胞的活动细胞。要发挥作用，精子的形态必须是正常的，精子必须获得运动能力。通常，动物(和人类)男性不育与精子形态和功能异常有关。一种表型，通常观察到的非功能性精子，是由“脆弱的”精子连接件引起的精子头分离。对于养牛业来说，高公牛繁殖力是重要的，也是具有经济后果的。

Spermatozoa are motile cells that transfer the father's genetic information to the oocyte. To function, sperm morphology must be normal, and sperm must acquire motility. Often, animal (and human) male infertility is related to abnormal sperm morphology and function. One phenotype, commonly observed for non-functional sperm, is sperm head detachment caused by a "fragile" sperm connecting piece. For cattle industry, high bull fertility is important and of economic consequence.
