Patient's question:
Male, 27 years old, married for 2 years and has no children with his wife.Doctor's answer:
Sperm antigens have the ability to induce specific autoimmune and allogenic immune responses. If antisperm antibodies are present in blood, seminal plasma, or on the surface of sperm, the sperm may exhibit head-to-head, tail-to-tail, or mixed agglutination, affecting fertility and leading to infertility. In men, immunological infertility is primarily characterized by symptoms such as fatigue, lack of vitality, and sluggishness, while semen parameters remain within the normal range but evidence of antifertility immunity is present. In women, immunological infertility symptoms may manifest as normal ovulation and reproductive tract function, yet infertility persists despite the absence of underlying pathological factors. In some cases, immunological infertility may also involve anovulation and amenorrhea. Those diagnosed with immunological infertility should seek proper medical examination and treatment at hospitals.
