1. Color inspection
[Normal reference value] Gray or milky white, those who have not ejaculated for a long time can be light yellow.
[Clinical significance]
1. Yellow or brown purulent semen: See seminal vesiculitis or wait.
2. Belly red or dark red hematological semen: Flames, tuberculosis and tumors of the reproductive system.
Second, the amount of liquid volume
[Normal reference value] 2-5ml.
[Clinical significance]
1. If it is not ejaculated for several days and the amount of semen is less than 1.5m1 is not normal, it means that the seminal vesicles or prostate have lesions; if the amount of semen is reduced to several drops, it can not be discharged.Specific infections, such as tuberculosis, gonorrhea and non -specific inflammation.
2. If the amount of semen is too large (exceeding 8m1 at a time), the sperm is diluted and reduced accordingly, hindering fertility.
Third, viscosity and liquefaction inspection
[Normal Reference Value] Viscover jelly, liquefy by yourself within 30 minutes.
[Clinical significance]
1. Low semen's viscosity, like rice soup, can be caused by the reduction of sperm weight, and is found in inflammation of the reproductive system.
2. Excessive or non -liquefaction in liquefaction time can inhibit sperm activity and affect fertility. It is common in prostate inflammation.
Fourth, sperm activity detection
[Normal reference value] Normal sperm vitality is generally in level III (better activity, medium speed exercise, but more waveform movement) above, and the ability should be> 0.60 within 1 hour after ejaculation.
[Clinical Significance] If level 0 (dead sperm, no activity ability, no activity after warming) and level I (poor activity, sperm rotation, swinging or shaking, slow exercise) SpermOne of the important causes of childbirth.
Fifth, sperm activity detection
[Normal reference value]
30-60 minutes after ejaculation is sperm of level III or above> 0.80;
Sperm with a mobility of level III or above within 120 minutes after ejaculation> 0.60;
0.25-0.60 sperm after 120 minutes of ejaculation can still move.
[Clinical Significance] Increased sperm with poor activity or increasing activity is one of the important reasons for infertility.It is common in spermatic varicose veins and non -specific infections such as E. coli infection. Some metabolic drugs, anti -malaria, estrogen, nitrogen oxide must also reduce sperm activity.
Six, sperm count
[Normal Reference Value] (100-150) × 109/L or the total number of ejaculation is (4-6) × 108.
[Clinical significance]
1. The sperm count is less than 20 × 109/L or the total number of sperm is less than 1 × 108 is not normal. It is found in the impact of harmful industrial pollution, large dose radiation and certain drugs such as sperm veins and lead metal.
2. The semen has not found the sperm as no sperm. It is mainly seen in the testicular sperm function of the sperm, and the congenital vasters, the seminal vesicles defect or the transmitting tube obstruction.After 2 months of transfusion tube ligation, there should be no sperm in the semen, otherwise the surgery fails.
3. The elderly have decreased from the age of 50 and even disappeared gradually.
