Problem analysis: Semen refers to the liquid discharged from urethra when male animals or human males ejaculate (usually in an orgasm state). Normal semen is a viscous liquid mixture composed of sperm and seminal plasma.
Guidance and suggestion: the quality of semen can be judged from the following points: 1, and the amount of semen: normal 2 ~ 6 ml. 2. Color: normally grayish white or yellowish. 3.pH value: The normal pH value of semen is 7.2~7.8. 4. Liquefaction time: After normal semen is injected, it becomes gelatinous under the action of seminal vesicle coagulase and liquid 15 ~ 30 minutes under the action of prostatic liquefaction enzyme, which is semen liquefaction. 5. Viscosity: The glass rod is contacted with liquefied semen and gently lifted to form semen filaments, the length of which is generally less than 2cm. 6. Sperm count: Normal count ≥ 20 million/ml.
I wish you the best of health!
