Color: The normal color is grayish white or yellowish. If the semen appears milky white or yellow-green, it means that there is inflammation in the male reproductive tract or accessory gonad. If pink or red or red blood cells can be seen under the microscope, it is bloody semen, which is common in patients with accessory gonad and posterior urethral inflammation, and occasionally in patients with tuberculosis or tumor. If there is yellowing phenomenon, and it is a short-term yellowing phenomenon, it may be because the interval between sperm discharge is long and the abstinence time is long. This situation will recover itself, so don't worry too much.

Liquefaction time: After normal semen injection, it will become gelatinous under the action of seminal vesicle coagulase, and after 15-30 minutes, it will become liquid under the action of prostatic liquefaction enzyme, which is called semen liquefaction. If the semen has not liquefied after 60 minutes of injection, it is abnormal liquefaction.

Viscosity: Touch the liquefied semen with a glass rod, which will form semen filaments after being gently lifted. Normal semen drips in the form of dispersed droplets. If the viscosity is abnormal, the droplets form a line with a length of ≥2cm.
Sperm number: generally expressed by the number of sperm per milliliter of semen. The standard count of normal semen is ≥20× 10? 6/ ml. Below this value, there are too few sperm, which can be seen in the dysfunction of spermatogenesis caused by various reasons, which can lead to low fertility or infertility due to the decrease of the chance of sperm entering the uterine cavity and fallopian tube. If the sperm count is greater than 250× 10? 6/ml means that there are too many sperm, which will also lead to infertility because the motility of sperm is affected.
Sperm morphology: sperm with normal morphology ≥50%, otherwise it may cause infertility.
Activity: Sperm moves forward rapidly in a straight line ≥50%.
Survival rate: Generally, it means that the live sperm is ≥50% when examined within after ejaculation 1 hour. The common reasons leading to the decline of sperm motility and survival rate are hypogonadism, varicocele, ciliary stagnation syndrome caused by chronic respiratory infection, the existence of anti-sperm antibodies in semen or improper preservation of specimens.
White blood cells: Is the white blood cell in normal semen 1× 10? 6/ ml. Leukocytosis indicates that there is infection in reproductive tract or accessory gonad.
