Male Sperm Shape
Male sperm shape is called its “morphology” and it too is measured. Abnormally shaped sperm often contain genetic errors of one kind or another that reduces the chances that perm will fertilize an egg. The more normally shaped sperm there are in his semen, the more likely a man will conceive a healthy child via unprotected sex with a woman. The number, motility, and shape of sperm all generally decline with age. Through many other factors can speed up the biological clock governing. The particular facet of man’s overall sexual health.
Heat for example is bad for sperm. Sperm production plummets in the days following a high fever. Anything that unnaturally warms the testicles, such as taking frequent soaks in a hot tub, will similarly hurt sperm. The shape of sperm is an indirect measure of the quality of the genetic information they contain, but in recent years it’s become possible to directly probe the integrity of the genetic information in individual sperm cells. This is a fairly new field of scientific exploration because it’s only recently that the entire human genome has been mapped and techniques for rapidly sampling genetic information have been invented. Research to date clearly shows that a range of genetic problems in sperm get worse with age. These include hemophilia A, Neurofibromatosis, Marfan syndrome, and polycystic kidney disease
