Does the man's quality of sperm have something to do with his weight
A lot of people see this title will be confused, does the man's quality of sperm have something to do with his weight? The modern scientific research investigation shows, such is the case. A new studying and revealing that is announced at human reproduction and embryology meeting of Europe held in Barcelona of Spain, fat men compare with man normal in waistline, there are more inferior sperms. This means the fatter men are, the worse reproduction ability is, even know sterility.
Britain Aberdeen university think while being inferior while being lucky and the intersection of sand and the intersection of leaf and research group of cloth analyze Scotland more thanth sperm of man, according to the body performance figure (BMI) at the same time ,Namely weight (kilogram) Divided by height (rice) The square of, divide these men into different groups. BMI is the normal weight among 20~25, 25~29 is overweight, 30 and the above is fat. Result indicate BMI have high normal sperm of level in 20-25 man, and and the overweight person is seminal fluid quantity ( sperm's quantity) Less, and the normal sperm is not large in quantity. The fat man's probability of having less sperms is above 60%, and its probability with unusual sperm is above 40%. The overweight one is similar to situation of the fat man. Sand the intersection of leaf and cloth wait for someone under study for action getting rid of, may influence the factor that the sperm counts while being other, such as smoking, drinking, abusing medicine and age,etc., verify the fat really influences sperm counting and sperm's quality.
Why will fat influence the man's quantity of sperm and quality? Have some theory and hypothesis now, compare until admit three among them. First, the adipose tissue will influence the supersession of sex hormone, therefore may hinder production and sperm's quality of the sperm. Second, it would cause the negative effect that the temperature may produce the sperm. People's normal body temperature is about 37 , and the best temperature which the sperm produces should be 2 degrees centigrade lower than normal temperature. Fat men have more fat, therefore their body temperature is higher than that of normal people. The temperature of the scrotum position is high, will influence growing precise ability of the testis directly, cause sperms to produce and reduce; Even if it is not influenced that the sperm produces the quantity, but the quality of sperm after producing will be influenced.
Even so, researchers can't confirm fatly that will certainly cause sterility, this must see other factors. For example, the fat man marries normal woman, the bearing the function of the fat man will be compensated by the other side, therefore might not cause sterility. However, if the fat man binds with fat woman, two people's fat will be superposed and formed and enlarged the effect, cause sterility.
In addition, the fat will initiate diabetes or recessive diabetes, this disease will do harm to sperm, and influence male fertility. As to this, the research of other researchers has been proved. Belfast queen Cohan of the university? Though not overweight men who suffer from diabetes find while treating that guide Sri Lankan to 40 in Mali, because of suffering from diabetes, the candy level is relatively high in patient's blood, therefore DNA in their sperm of damage. They find, it is that have not suffered from twice of normal and male diabetes to suffer from the probability that the glycosuria patient's sperm damages.The editor recommends:Will the man die smartly to the limit
