Indicators of routine semen analysis mainly include: semen volume, color, liquefaction time, sperm count, sperm motility, sperm morphology and so on. 1. Semen volume: Generally speaking, the volume of semen in adult men is around 2~6ml per ejaculation, too little or too much may be abnormal. 2. Color: milky white, white, colorless, light yellow and other colors are common, if there is brown, red, reddish-brown, etc., we should be vigilant about infectious lesions of the genitourinary system, hemorrhagic lesions and other conditions. 3. liquefaction time: after ejaculation, semen is often manifested as a viscous liquid, which can then be liquefied, conducive to spermatozoa swimming. Generally, under the condition of 37 degrees Celsius, it can be liquefied in about 5~25 minutes. If the liquefaction time is too long, infertility may occur. 4. Sperm count: Generally, the sperm density is about (100~200)*10^9/L. According to the comparison of the test results, the sperm count of the patient is clear. 5. Sperm motility: the standard of sperm motility is grade A + B + C ≥ 60%. If sperm activity is not strong, it may lead to fertility difficulties. 6. Sperm morphology: mainly refers to the percentage of deformed sperm, the sperm deformity rate is 20%~40%, according to this result, we can analyze the sperm quality of the patient. To summarize, if there are reproductive diseases, you should seek medical treatment in time.
