Sperm's shape influences _'s health care of fertility
There is research report that proposes, the medical circle should revise the inspection standard of the male sterility, propose reflecting male fecundity to the shape of the sperm. The report proposes, have made the regulation making it rigidly uniform in right male fecundity of standard that World Health Organization made half a century ago, the sperm counts and greater than or equal to 20 million ml, it is that the fecundity is normal that sperm activity is counted and greater than or equal to 50%, lower than this number valueing is sterility.
But a lot of doctors find, some are " sterility " in practice Performances man bear children,belong to and part " normal " Man but always work as father. It is obvious male viability regards in the men of the ashy areaing as a sterility patient to treat and really waste the time and money in an ashy area.
British researchers unite to 765 sperms of male sterility and 656 pairs of new standards which married couple already with childrens make after studying: The sperm counts and is greater than or equal to 48 million ml, the activity is counted and greater than or equal to 63%, more than 12% of the sperm shapes are normal, considered to be normal fecundity; The sperm counts and is less than or equal to 13,500,000 ml, the activity is counted and less than or equal to 32%, the normal sperm is less than or equal to 9%, but have no fecundity. If the seminal fluid inspection result is in the ashy area between these two, such a man may have fecundity, it may be of no use too.
This research emphasizes that checks and can reflect male fecundity most in morphology of the sperm, the normal sperm should contain a oval tail as whip of head end, the head end is shown in round or too big, the sperm that the tail rolls up is unusual.
