What does a man’s normal semen look like?

　　1. Semen volume

　　The normal semen volume is 2 to 6 ml. If the amount of semen discharged at one time is more than 6 ml, it is considered to be excessive semen volume. If the amount of semen discharged at one time is less than 1.0 ml, it is considered that the semen volume is too small. The amount of semen is related to the length of abstinence. The longer the abstinence time, the greater the semen volume, and vice versa. Therefore, when we do semen examination, we usually instruct the patient to collect semen 4 to 5 days after sexual intercourse, so that the results of the examination will be relatively accurate.

　　2. Appearance of semen

　　Freshly ejaculated semen is jelly-like, gray-white or gray-yellow. When the semen is liquefied, it becomes translucent milky white or milky yellow. The semen ejaculated by those who have not ejaculated for a long time will be darker in color. elderly Most of the semen is dark yellow.

　　3. The smell of semen

　　Normal semen has a special fishy odor, which some people compare to the smell of chestnut flowers, while others describe it as the smell of papaverine. This odor is caused by the oxidation of polyamines in prostatic fluid. The longer the period of abstinence, the stronger the smell.

　　4. Semen liquefaction time

　　Liquefaction of semen is the process of semen changing from jelly to liquid after ejaculation. Normal semen liquefaction time is 30 minutes. If it exceeds 30 minutes, the semen is not liquefied or is incompletely liquefied.

　　5. Semen viscosity

　　After the semen is liquefied, it becomes a viscous liquid. Use a straw to stick the semen downwards naturally. If the semen is in discrete droplets and drips drop by drop, the viscosity is normal. If there are long (2 cm) mucus strands, the viscosity is too high. Semen that is not liquefied, incompletely liquefied or has too high viscosity will affect sperm mobility, causing infertility.
