You can judge whether the sperm is low based on semen volume, semen color and semen consistency. 1. Semen volume: A healthy adult man ejaculates 2~6ml of semen. If the amount of semen discharged by a man is much less than this range, the amount of sperms in his ejaculate may be relatively low. 2. Semen color: the normal color of semen is generally off-white and slightly yellow, if the color of the ejaculated semen changes, including obvious yellow-green, milky white, etc., the local may be suffering from inflammatory diseases, which may lead to the ejaculation of semen in the amount of spermatozoa is relatively small. 3. Semen urine consistency: If after ejaculation, the ejaculated semen is thinner or forms a semen filament after contacting and extracting it with a glass rod, then the sperm content in the semen will be less. If you need to determine whether you have fewer sperm, you can judge according to semen volume, semen color and semen consistency. It is recommended that patients go to regular hospitals for relevant examinations to make a clear diagnosis.
