Abstract
Summary
The fluorescent antibody technic was employed to determine the presence of normal antigens of sperm, seminal fluid, and testis in various testicular tumors. Ten testicular tumors showed no staining with any of the antisera made to the above normal antigens. These results show that there are components unique in testis which can be stained with antibody against testis, seminal fluid and sperm but these components were not present in the several testicular tumors tested at a concentration high enough to be observed. Some differences were noted between the anti-seminal fluid, anti-sperm and anti-testis sera. The 3 sera reacted with sperm cells. Anti-sperm and anti-testis in addition to staining sperm cells reacted with stromal elements in testis. The latter serum also contained antibodies to germinal epithelium.
