The sperm of all athletic ability are of motile sperm. Sperm motility (live rate) is based on the activities of forward movement of sperm that have the ability to calculate the percentage of sperm, and
Generally divided into 5 grades: 0 indicated that the sperm can not be activities; one that sperm mobility is poor, only in-situ creep; 2 that sperm motility in general, only the forward curve of movement; 3 indicated that sperm good, straight to the pre-exercise; 4 indicated that excellent sperm, showing rapid linear forward motion. Normal, 3 and 4 of and should be more than 50% motile sperm in at least 25% of the sperm linear fast motion. If the 0,1,2-class sperm more than 50%, 4 less than 25%, that is, asthenospermia.
Some of the sperm motility is divided into four: a class that excellent sperm, showing rapid linear forward movement; b-class that sperm good, straight forward movement; c-class that sperm motility in general, only forward curvilinear motion; d level that sperm mobility is poor, only in situ creep. Fast-forward movement of sperm A-and d-level is slightly slow forward movement of sperm B (A Grade + B Grade) "50% or A-sperm" 25%. ¢Ù mild asthenospermia is A-+ B-class sperm "50%, but" 30% or A-sperm "25%, but" 10%. ¢Ú moderately asthenospermia refers to A-+ B-class sperm "50%, but" 30%, of which A-sperm "10%. ¢Û severe asthenospermia refers to B-+ C-level sperm count "30%, of which A-sperm is zero. Asthenospermia, the sperm unable to forward, it is difficult through the cervix tubes, uterine cavity, fallopian tube with the egg directly, resulting in low fertility.
Led to asthenospermia common reasons: 1, testis seminiferous epithelium are not fully mature or damaged thinning, resulting in poor quality sperm, activities, weak; 2, semen less; 3, seminal plasma variability, such as the epididymis, seminal vesicle , prostate, etc. When there is inflammation, pH, oxygen, nutrition, metabolism, and other activities and are not conducive to sperm survival; if there is anti-sperm antibodies, can make sperm agglutination, which has lost its ability.
