[Immunoglobulins in serum and seminal fluid in patients with sperm agglutination]

Serum immunoglobulins and immunoglobulins in the seminal fluid were determined in 32 men with normospermia without agglutination and in 37 men with normospermia with agglutination. In the seminal fluid also secretory IgA and the secretory component were recorded. The values of serum immunoglobulins were more or less the same. So were the IgG values in the seminal plasma of both groups. IgA was found more frequently in the seminal plasma of patients with agglutination. IgM was not found at all. Secretory IgA and the secretory component were for the most part found in the seminal plasma of patients with normospermia and agglutination. The finding of secretory IgA and the secretory component gives an insight into the local synthesis of sperma-antibodies.
