Anti-sperm antibodies of 18 in males suggests excess, which may be caused by trauma, inflammation, etc., resulting in disruption of the blood-testis barrier and the production of anti-sperm antibodies in the blood, which may cause infertility in severe cases.
Normal male organism should not have anti-sperm antibodies, normal should be <2, and when the male anti-sperm antibody is 18, it is higher than the normal value, suggesting positive.
Antibodies are generally produced by the immune system stimulated by antigens. Generally, testicular trauma and orchitis may cause immune cells in the blood to enter the testicles and use sperm as antigens, thus producing antibodies against sperm, i.e. anti-sperm antibodies, which can easily block the combination of sperm and egg, and infertility may occur in severe cases.
Therefore, when men have excessive anti-sperm antibodies, the cause should be clarified and actively treated under the guidance of a doctor.
