The objectives were to standardize some methodological and analytical aspects of a direct technique to detect sperm-bound anti-sperm antibodies ASAs in bovine semen using flow cytometry, including the effects of pre-fixation of sperm membranes with formalin buffer solution and inclusion of dead cells in the analysis. Fixation of sperm membranes had no significant effect on the percentage of IgG- or IgA-bound spermatozoa detected by flow cytometry. However, including dead cells in the analysis increased the percentage of IgG-bound spermatozoa in fixed live and dead

Sperm are allogenic to the female genital tract; however, oviducts provide optimal conditions for survival and capacitation of these non-self cells until fertilization. Recently, we showed that oviduct-conditioned media and prostaglandin E 2 PGE 2 suppress sperm phagocytosis by polymorphonuclear neutrophils PMNs under physiological conditions. As the first step to obtain basic information, sub-confluent BOEC monolayers were co-cultured with swim-up sperm for 2 h.
