Immune infertility is a common type of male infertility disease. The cause is mainly related to antigen in the sperm, as well as sperm antigen and anticipated antibodies.
1. The antigen in the sperm pulp
Human semen can be divided into two parts: clear sperm pulp and sedimentary sperm after liquefied centrifugal treatment, both contain antigen and antibodies. Among them, there are many types of sperm slurry antigen.It is a specific antigen for semi -slurry, mainly from prostate, seminal vesicles, and epididymia. To a certain extent, it affects men's fertility function.
2. Sperm antigen
The sperm antigen is mainly attached to the sperm plasma on the sperm surface, including lactin produced by the seminal sac.These sperm antigens will induce the corresponding antibodies. Under the participation of the body, it can lead to sperm motility disorders, which in turn causes the adverse consequences of male infertility.In addition, the sperm membrane antigen that has entered the molecular level after research has entered the molecular level. It is rich in a variety of rock alcohol, galactose, N-acetyl hypalidumine, etc. on the sperm surface, which not only affects the ability to identify sperm and eggs.The corresponding antibodies can also cause fertilized disorders, etc., which is a major cause of immune male infertility.
3. Anti -sperm antibody
Anti -sperm antibody is a medium antibody caused by the blood test barrier or dysfunction caused by immunosuppressive dysfunction.Infertility occurred.
