According to the normal semen standards stipulated in the World Health Organization, judging whether semen is normal can be analyzed from the following aspects:
(1) Semen: Normal & Ge; 2ml.When it is more than 7ml, it is too much. Not only is the sperm density decreased, but it is also easy to flow out of the vagina, so that the total number of sperm is reduced, commonly in seminal vesiculitis; less than 2ml is too much semen, but it usually takes less than 1ml.At this time, the area of contact with the female genitals is small, or it is infertile due to viscosity that is not conducive to the sperm entering the woman's cervix. It is common in severe adenitis, low testosterone levels, obstruction of ejaculation pipes, retrograde ejaculation, etc.
(2) Color: Normally gray -white or slightly yellow.Milky white or yellow -green indicates that the reproductive tract or adrenal glands have inflammation; those who see red blood cells under pink, red, and microscope are herediest semen, which is common in inflammation of the paranexical gland and posterior urethra, and occasionally can be seen in tuberculosis or tumor.
(3) Poisphan degree: The pH value of the normal semen is 7 2-7 8.Smaller than 7 2 is found in the obstruction of the ejaculation tube or is contaminated by urine; greater than 7 8 is found in seminal vesicular inflammation or old specimen.
(4) LPG time: After the normal semen is ejected, it becomes jelly -shaped under the action of seminal vesicles, and it becomes liquid under the action of prostate liquidase in 15-30 minutes. This is semen liquefaction.After 30 minutes of ejaculation, the semen still does not liquefy is abnormal.
(5) Visation: Gently hold the glass rod to the liquefied semen and gently hold it, which can form semen wire. Normally, its length is less than 2 cm.
(6) Sperm count: Generally represented by the sperm number per milliliter semen.Normal count & ge; 20 × 10? 6/ml.If this value is too small, the sperm disorders are found in various reasons. The chance of fertility or infertility can be low or infertile due to the reduction of the opportunity to enter the uterine cavity and fallopian tubes.For example, if the sperm count is more than 250 × 10? 6/ml is too much sperm, it can also cause infertility due to its activity.
(7) Sperm form: 50%of sperm & ge;
(8) Mobility: List in the sperm quickly move forward & ge; 50%.
(9) Survival rate: usually check within 1 hour after ejaculation, live sperm & ge; 50%.Common causes of sperm activity and reduced survival rates include side adrenal inflammation, sperm varicose veins, chronic respiratory tract infection, cilia dull syndrome, and improper storage of anti -sperm antibodies or specimens in semen.
(10) White blood cells: <1 × 10? 6/ml in normal semen.Increased leukemia indicates that the reproductive tract or adrenal glands are infected.
