What are the causes of immunological infertility?

Patient's question:

I had an abortion last month, and now I always feel discomfort down there, a bit itchy, and also have a lot of discharge, which is yellow and smells foul, like a rotten egg. What could be going on? Also, what are the causes of immunological infertility?

Doctor's answer:

1. Same autoimmune: Refers to the sperm and seminal plasma of the male acting as antigens in the female body, producing antibodies that cause sperm agglutination or loss of motility. Under normal circumstances, women do not produce autoimmune reactions, but approximately 15%-18% of infertile women have anti-sperm antibodies.
2. Local autoimmune: Refers to some infertile women whose cervical mucosa and endometrium contain lymphoid cells that produce immunoglobulin G and A, and the cervical mucus contains anti-sperm immunoglobulin G, A, and M. Therefore, the cervix and female reproductive tract have a local autoimmune effect against sperm. Immunological infertility is a gynecological disease that is prone to occur. During medication, women need to pay attention to their own care, especially in terms of hygiene. It is recommended that patients pay close attention to maintaining external genital cleanliness and changing underwear frequently. Finally, we wish female patients the best.
