Waistline the more big sperm be more bad

  Lately, at Spain Ba Sai that hold of Europe the mankind grow with embryology meeting top announce of a new of research manifestation, fat male and waistline normal of male compare, the inferior sperm be more.This mean man's waistline it's more big, grow ability more bad, even will not teach.

  England the elder brother of one's father D university Ji be second to think ·the research group of the sand leaf's cloth analysis Scotland the sperm of more than 5000 men, in the meantime according to body quality index number(BMI), namely weight(1000 gram) in addition to with the square of height(rice), will these male be divided into dissimilarity of set do not.BMI's ising between 20~25 is a normal weight, 25~29 is an excess, 30 and above is fat.

  Result enunciation that the BMI own at 20~25 mans be higher level of normal sperm, but excess and fat not only semen quantity(sperm amount) less, and normal the sperm amount be also few.The fat man own several rate of the sperm of less in above 60%, but it take to have abnormality several rate of the sperm also in above 40%.The circumstance of excess and fat man about.The sand leaf's cloth wait for someone in the research expel other possibility the influence sperm count of factor, such as smoke cigarette, alcohol, abuse medicine and age etc., confirmation fat really influence the sperm count with sperm quality.

  Why fat would the influence man's sperm amount and quality?Now has some ories and hypothesis, among them comparison what to get an approbation be 3 kinds.While is a fat organization would influence arrive sex hormone metabolism, may hinder sperm from here of born with sperm quality.Two is a temperature may be born to sperm to result in negative influence.The person's normal body temperature is 37 ¡æ be or so, but the sperm born best temperature want lower than normal temperature 2 ¡æ .Fat man's fat is more, as a result their body temperatures be higher than normal person.The temperature Gao of the scrotum part, would direct influence arrive the living of testicle Jing ability, make sperm born decrease;Even sperm the born mount be uninfluenced, but born empress of the sperm quality will also be subjected to influence.

  The diabetic sperm injure many

  Moreover, it is fat to will cause diabetes or recessiveness diabetes, this disease will also result in injure to the sperm, and therefore influence male of grow dint.To this, the research of other researcher gave a certificate.The shell Er method Si especially the section boon of queen's university ·the Mali Di Si rightness although 40 not excess but suffer from diabetes of male carry on treatment detection, in order to suffering from diabetes, the sugar level be higher in the sufferer blood, from here injure they the DNA in the sperm.Their detection, suffer from the sperm of diabetes injure of several rate is do not suffer from diabetes normal male of 200%.

  For all that, the researcher still can't confirm fat certain result in to teach not, this still have to see an other factor.For example, fat man with normal woman get married, fat the function of grow of man will get the other party compensate, as a result uncertain will result in to teach not.But, if the fat man combine with fat woman, two people of fat will fold to add and formation enlarge an effect, result in to teach not.
