Anti-sperm antibody positive
Introduction
Introduction In infertility, males are mainly characterized by decreased sperm quality, decreased vitality, suboptimal viability, and even a large number of abnormal sperm, which makes some seemingly healthy men lose their normal reproduction unconsciously. Ability, although they are very surprised and helpless.
Cause
Cause
Women, because AsAb has the function of killing, phagocytosis, agglutination and braking sperm, it often causes the fat egg to be combined with a fatal "frustration". It can be said that "one yang" is not enough when the sperm enters the female reproductive tract. If it is not normal fertilization, it will cause rejection of sperm. Even if it is pregnant, it will often lead to miscarriage and premature birth, which will seriously interfere with fertility.

Male examination (pay attention to the history of chronic diseases such as tuberculosis, etc.) to understand living habits and difficulty in sexual intercourse, external genital examination for abnormalities, semen examination for abnormal normal semen volume 2-6 ml, ph7.5-7.8, liquefaction The time is not more than 30 minutes, the sperm count is more than 60 million per ml, the activity number is more than 60%, the abnormal sperm is no more than 15-20%, the sperm number is less than 60 million, the fertility is poor, and the condition can be further immunized and chromosome an examination.
The woman examines the following examination in addition to the detailed examination of the medical history.
1, gynecological examination to understand the development of internal and external genital inflammation, tumors and deformities, check for galactorrhea.
2, vaginal discharge examination of the vaginal pH and related inflammation and sexually transmitted diseases, including trichomoniasis, Candida gonococcus and chlamydia and other tests.
3, tubal fluid examination or hysterosalpingography.
4, ovarian function test.
Diagnosis
Differential diagnosis
Too many dead sperm: Death syndrome refers to multiple semen examinations, and sperm are dead. Under normal circumstances, semen excreted within 1 hour of the body, the normal survival of sperm should be more than 70%, such as dead sperm more than 40% will affect pregnancy. Sperm survival time should maintain a 6-hour survival rate of more than 20%, such as no survival of sperm within 6 hours, can cause infertility.
Low sperm survival rate: sperm survival rate (dead sperm is greater than 50%), sperm morphology (normal morphology sperm less than 70%), semen acid phosphatase (less than 2.5 to 60,000 units / ml), semen fructose (lower than 150 ~ 800 mg / 100 ml).
Low sperm motility: Sperm vitality is an indicator of the comprehensive evaluation of sperm quantity and quality. It includes the number of normal active sperm in semen, ie sperm motility, and the quality of normal active sperm, ie sperm motility. The method of diagnosis of sperm motility is not yet unified, but it tends to a five-level classification. The content is: level 0 is no vitality. Level 1 is poorly vibrating, indicating that the sperm moves or moves in place only. Level 2 is medium in vitality, indicating that the sperm swims straight ahead but is not active. Level 3 is good for vitality, indicating good sperm motility, and level 4 is very active, indicating that the sperm is actively moving forward in a straight line. Sperm hypoactivity refers to sperm motility below level 2, and the number of active spermatozoa is less than 50%.
