[An immunofluorescent study of circulating sperm antibodies in humans (author's transl)]. 1975

O M Maucher, and H J Heite, and G Vogel

1. By means of an indirect immunofluorescent technique with reference to Weller and Coons (1954), modified for spermatozoal immunofluorescence we found antibodies against spermatozoa in the sera of: 6 of 35 female partners of couples with unexplained infertility, 5 of 35 male partners of couples with unexplained infertility, 8 of 40 prostitutes, 8 of 18 men after orchitis and vasoresection. In contrast to these findings the sera of 20 fertile women, 25 fertile men, and 20 virgins showed negative results with the test mentioned above. 2. The site of the antigen-antibody reaction was mainly the spermatozoal tail and in the second place, the equatorial segment. 3. The immunoglobulins primarily belonged to the IgG and secondly to the IgA class. 4. Our results differ partly from the findings made by other authors perhaps on account of methodical differences. 5. The clinical relevance and associated problems are discussed.

UI MeSH Term Description Entries
D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007072 Immunoglobulin D An immunoglobulin which accounts for less than 1% of plasma immunoglobulin. It is found on the membrane of many circulating B LYMPHOCYTES. IgD,IgD1,IgD2
D007074 Immunoglobulin G The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B. Gamma Globulin, 7S,IgG,IgG Antibody,Allerglobuline,IgG(T),IgG1,IgG2,IgG2A,IgG2B,IgG3,IgG4,Immunoglobulin GT,Polyglobin,7S Gamma Globulin,Antibody, IgG,GT, Immunoglobulin
D007075 Immunoglobulin M A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin. Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM

D009920 Orchitis Inflammation of a TESTIS. It has many features of EPIDIDYMITIS, such as swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS and then the TESTIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD. Orchitides
