(1) Semen quantity: normal semen standard semen amount & ge; 2ml.Among them, excess semen is deemed to be greater than 7ml.too little.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.

(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 with urine; greater than 78 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.

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.If the sperm count is greater 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.
