To determine the quality of sperm in general can be judged from the following aspects: 1. the amount of semen ejaculated at one time, clinical statistics show that the amount of semen ejaculated at one time by a normal male is about 3-6ml. If the patient’s semen volume is low for a long time, it may be less sperm, and if the semen volume is high for a long time, the density of sperm will be a problem. 2, the color of semen, the color of normal male semen is a milky white jelly-like liquid, after a while it will turn into a transparent flowable water-like liquid, if the color is yellow or red is abnormal. 3, you can also judge by the smell of semen, normal semen is almost odorless or If there is a fishy smell, it means there is a problem. The most detailed and specific way of observation is to suggest that the patient go to a regular hospital for a sperm quality check.
