Some research reports suggest that the medical community should modify the examination standards for male infertility, and proposes to reflect the fertility of men in the form of sperm.The report pointed out that the standards set by the World Health Organization in half a century have made a knife -cut rule on men's fertility ability, that is, sperm number & ge; 20 million/ml, sperm activity & gery; 50%is normal for fertility, lower than this, lower than this, lower than this, lower than this, lower than this, lower than this, lower than this, which is lower than this, which is lower than this.Value is infertility.However, many doctors found in clinical practice that some men who belong to "infertility" have children and children, while some men who belong to "normal" are always not a father.Men are used as infertility patients to treat time and money.
Researchers from seven universities in the UK jointly conducted a new criterion for the sperm of 765 infertile men and 656 to study couples who already have children.More than 12%of the sperm form is normal, it is considered to have normal fertility; sperm & le; 13.5 million/ml, activity & le; 32%, normal sperm & le; 9%, is no fertility.If the semen test results are in the gray area between the two, such men may have fertility or not.
This study emphasizes the morphological examination of sperm is the most fertility ability to reflect men. Normal sperm should contain an oval head end and whip. The head end is round or too large.of.It is gratifying that Beijing Tianlun Hospital has carried out routine examinations in this area, which has a very important guiding significance for clinical diagnosis and treatment of male infertility patients.
