The main examination items include semen appearance, semen volume, semen liquefaction time, semen pH value, and sperm motility.

Generally, a routine semen analysis is an important method for evaluating male fertility. The main examination items include semen appearance, semen volume, semen liquefaction time, semen pH value, and sperm motility. If discomfort symptoms occur, it is recommended to seek timely medical consultation and follow standardized treatment under a doctor's guidance. Detailed analysis is as follows:

1. Semen Appearance

Semen typically appears乳白色, grayish-white, or jelly-like, with a semi-fluid consistency. If the semen appears yellowish, reddish, or displays other abnormal colors, it may indicate inflammation or infection.

2. Semen Volume

The typical semen volume from a single ejaculation ranges between 1.5-6 ml. Either excessively low or high semen volume may affect fertility.

3. Semen Liquefaction Time

After ejaculation, semen usually liquefies within 15 to 30 minutes. Abnormal liquefaction time might suggest dysfunction of the prostate or seminal vesicles.

4. Semen pH Value

Semen is slightly alkaline, with a normal pH range of 7.2-8.0. Abnormal pH levels can affect sperm survival and mobility.

5. Sperm Motility

Sperm motility is a key indicator of sperm quality, generally assessed by sperm motility rate and sperm movement. Insufficient sperm motility may lead to infertility.

Routine semen analysis is a comprehensive evaluation of male fertility. By examining the above indicators, one can understand the quality of semen and the status of male fertility. If test results are abnormal, timely medical consultation and appropriate treatment are necessary.
