The possibility of the immunological factor as an etiological cause of infertility was investigated in 50 infertile couples. Of these, 31 couples were considered as an 'unexplained sterility' group, while in the other 19 couples a variety of disorders were diagnosed. In vitro, leucocyte migration inhibition test (LMIT) was used for the detection of female cell-mediated immunity against sperm antigens. Sperm immobilization test (SIT) and sperm toxicity tests (STT) were used for detection of antisperm antibodies in the cervical mucus. Out of the 31 'unexplained sterility' cases, six revealed a positive LMIT (5.3%). In 26 couples with an abnormal postcoital test (PCT), 10 cases had a positive SIT and STT (38.5%). However, out of the group of 16 couples with a normal PCT only in one case was a positive SIT and STT found (6.2%). The potential role of immunological reactions in infertility will be discussed.
