RESUMO
OBJECTIVES: To determine the level of anti-Toxoplasma antibody in serum of infertile couples to explore the relationship between toxoplasma infection and infertility. METHODS: Enzyme-linked immunosorbent assay (ELISA) was applied to detect the anti-Toxoplasma antibody, antisperm antibody (AsAb) and anticardiolipin antibody (ACA) in serum of 178 couples with infertility and 190 couples who had normal pregnant history. RESULTS: The positive result of Toxoplasma infection in the infertile couples was significantly higher than that in fertile couples which was 34.83% vs 12.11% (chi 2 = 26.72, P < 0.01) with the odds ratio 3.88. The positive result of serum AsAb in the Toxoplasma infected group was significantly higher than that in the no Toxoplasma infected group (32.50% vs 15.94%, chi 2 = 10.76, P < 0.01) with the odds ratio 2.54. CONCLUSIONS: Toxoplasma infection was related to infertility. The Toxoplasma infection and was posibly related to the antisperm antibodies which can be involved in the pathogenisis of infertility.
