Antigenicity of Spermatozoa even autologous sensitization using rabbits, bulls, guinea pigs, and mice, have all been claimed to be successful (., 1900; ., 1922; ., 1924). The antigenicity of spermatozoa was confirmed later on by electrophoretic and serologic methods, with characterization of the immobilizing properties of the潜伏期 发表于 2025-3-25 21:31:07
Antigenicity of Seminal Plasma recent investigations (. and ., 1960) emphasize the complexity of semen and the need to consider sperm and seminal plasma antigens separately. The high antigenic potency of seminal plasma obtained by centrifugation of whole semen has been repeatedly confirmed. Serologic techniques and immunoelectroAspiration 发表于 2025-3-26 03:25:01
Antibodiesories. The first comprises those called humoral or circulating antibodies, predominantly formed by plasmocytes; they may be detected by their ability to develop local or general anaphylaxis, to fix complement, to agglutinate antigen-coated red cells by immunoelectrophoresis, precipitation curves, an燕麦 发表于 2025-3-26 06:50:35

Pathogenesisith the corresponding humoral antibody or sensitized cell constitutes a trigger mechanism which may activate the complement system and probably induces the release of mediators such as histamines, serotonin, or bradykinin-like substances.
