Assessment of the relevance of zona pellucida antibodies in serum and cervical mucus in patients who have fertilization failure during in vitro fertilization.
OBJECTIVE: To assess whether antibodies to the zona pellucida can cause fertilization failure during in vitro fertilization ( IVF). DESIGN: Two methods for detecting zona pellucida antibodies were used to assess 20 women undergoing IVF. Nine patients had failed fertilization during the treatment cycle. SETTING: Academic IVF department of a teaching hospital. PATIENTS: Infertile patients previously assessed as requiring IVF. INTERVENTIONS: Gonadotropin-releasing hormone analogue to achieve pituitary down regulation and human menopausal gonadotropin for superovulation. Transvaginal ultrasound directed oocyte recovery. Cervical mucus and serum samples were obtained. MAIN OUTCOME MEASURES: The presence of antizona pellucida antibodies in serum or cervical mucus in relation to fertilization. RESULTS: Seven of 20 patients had antizona antibodies in serum and 7 of 20 patients had antibodies in mucus. Only 1 patient had antibodies in both samples. No correlation between the presence of antibodies in either sample and failure of fertilization was found. CONCLUSION: Detection of antizona pellucida antibodies by the methods described have no role in the prediction of IVF.[1]References
