About the quality of the sperm index analysis

Sperm count measure is an important index of fertility, but in the analysis, must be combined with individual specific situation.

1) sperm quantity: each row of normal 2 ~ 5 m1, if less than 1 m1, which is not normal. Pure (0.5 ml each row for sperm to reduce disease, such as no sperm for no refined disease. No refined disease and capable to reduce disease is the main cause of male infertility. Seen in the seminal vesicle or pathological changes, congenital ureteral occlusion, or inflammatory stenosis, or retrograde row essence.

2) color: normal for hoar, long when not ejaculation can be pale yellow, ivory or with green in the genital tract or vice live glands have infections; Semen redness (blood fine) in seminal vesicle phlogistic, the cancer, tuberculosis, etc.

3) series: normal fresh semen liquid from quickly into sticky glue Dong semiliquids shape, 5 ~ 30 minutes and into a liquid

If 30 minutes is still not liquefaction, is unusual, in: some of the enzyme secretion prostate lack or inadequate, but also in reproductive system n/med tuberculosis, also can affect fertility.

4) pH (pH) : normal is alkalescent, pH was between 7.7 and 8.5 semen overly basic or acidic may affect sperm activity and metabolism, is causes the sperm death (dead sperm disease) main reason.

5) bouquet: with special smell of normal sperm, issued by the prostate liquid, the smell of the prostatic secretion from a composition.

6) sperm count: normal fertile man, every milliliter semen containing the sperm 0.6 ~ 150 million, sometimes up to 200 million. A row of pure from the total number of sperm about 300 million or more, but the content of sperm great variation, because of the person different, even though the same individuals in different time, can also have access. Therefore, from the total number of sperm every time calculation, the diagnosis value than single check sperm counts more significance.

Sperm density is too high (every milliliter more than 250 million) called sperm too much disease, high density, often affect sperm activity, even if pregnant, also easy to occur abortion, the main cause is the sperm itself quality is not high.

For evaluation of male fertility, also be used fertility index (I) for research. Mainly in the percentage of the sperm activity (M), every milliliter semen sperm count (N), sperm movement speed (V), the percentage of the sperm deformity (A) and 10 for constant combination calculation, the formula is: I = M.N.V. / A. 106, if more than one, says fertility, if "0", and completely sterile, if be in between 0 ~ 1, says there are possible fertility.
