Immunological Differentiation of Human Testicular (Spermatocele) and Seminal Spermatozoa.

Abstract
Spermatozoa from spermatoceles lack the antigenic material present in seminal spermatozoa. This provides direct evidence that human spermatozoa (like those of rabbits) acquire antigenic material during their passage through the adnexal glands of the genital tract.
