The Egg (oocyte) is enclosed in a protein coat called as Zona Pellucida (ZP) through which the sperm has to penetrate in order to fertilize the egg. If there is any defect in sperm morphology it will find difficulty to penetrate the ZP. Shape Abnormality of Sperm: Abnormal sperms shape often contain abnormal DNA.It may have an extra chromosome, short of a chromosome or the DNA is packed in head in such a way that, if it penetrates the ZP, the DNA would get all tangled up when it tries to form a chromosome inside the egg. Therefore, the nature has evolved a way to keep abnormally shaped sperm from getting inside the egg and thereby maximizing the genetic development potential of the embryo. There are three main causes of poor sperm morphology:
