Autoimmune mechanisms represent a less common but clinically significant cause of male infertility. Anti-sperm antibodies may develop following trauma, infection, or surgical procedures such as vasectomy reversal.
These antibodies impair sperm motility and hinder sperm–egg interaction. Diagnostic evaluation includes immunobead testing and mixed antiglobulin reaction assays.
Treatment options may involve corticosteroid therapy in selected cases or assisted reproductive technologies such as intracytoplasmic sperm injection (ICSI), which bypass antibody interference.
Understanding immune-mediated infertility allows for targeted erotic and effective therapeutic planning.
