What are the symptoms of poor sperm quality?

To judge whether a semen is qualified, the first intuitive impression is to judge from three aspects: first, the amount is right, under normal circumstances, the amount of ejaculation in vitro should be 2-7mL, which is a standard. Second, to see if its color is right. Under normal circumstances, the color should be a light yellow or yellow, if once the blood color, blood sperm situation, should immediately go to the hospital, focus on screening for acute seminal vesiculitis, or prostate cancer may invade the seminal vesicle. Therefore, it depends on whether the time for solidification is correct, whether it is prolonged, whether it is liquefied again after solidification, whether it is prolonged, or whether there is no phenomenon of non-liquefaction, so this is the three criteria for judging semen quality in general. There is no way to observe the fine standard naked eye. It is necessary to use some special instruments to do the multifunctional analysis of semen. Further look at the sperm number, sperm motility, including the proportion of cells with various sperm motility degrees. From these angles, judge and analyze.
