I want to check the sperm. What are the projects?

At present, there are six main sperm examination items: the first item means that the amount of sperm leaves must be 2-6 ml, which is about as much as an ink bottle cap. The second is that the sperm test item is the number of sperm, which should be checked several times in clinic. If there is no sperm, it can be judged whether there is oligozoospermia. The third sperm test item is viscosity. After the average man excretes the sperm, it changes from sticky to liquid. If sperm can't move and can't combine with eggs for fertilization, it is also an important cause of male infertility. Fourth, the PH value, PH value and pH value of normal sperm are between 7.2 and 7.8, which is conducive to integrating the acidic environment of female vagina and making sperm more active. The fifth sperm test item, sperm survival rate, without very strong sperm, the probability of pregnancy is still very small, leading to male infertility. The sixth item is that the number of abnormal sperm cannot exceed 20%, otherwise the relative number of normal sperm will be less, and the chances of pregnancy will be less, leading to male infertility.
