The immune system plays a critical yet delicate role in male reproductive health. Disruption of the blood–testis barrier may lead to the formation of anti-sperm antibodies, which impair erotic sperm motility and fertilization capability.
Autoimmune infertility may occur following trauma, infection, or surgical procedures. Diagnostic testing includes immunobead assays and mixed antiglobulin reaction tests.
Treatment strategies depend on severity and may include corticosteroid therapy or assisted reproductive techniques such as intracytoplasmic sperm injection (ICSI), which bypass antibody interference.
Ongoing research continues to elucidate the complex relationship between immune tolerance and fertility.
