Correlation of human menopausal gonadotropin/human chorionic gonadotropin stimulation and oocyte quality in an in vitro fertilization program.
One hundred forty-seven cycles in normal ovulatory patients are reported. All were stimulated with human menopausal/human chorionic gonadotropin. Three estrogen responses were identified: normal, high, and low. Patients who achieved pregnancy formed a fourth category, the pregnancy group. The number of preovulatory and immature oocytes, the preovulatory and immature oocytes that fertilized normally or abnormally, the ones that cleaved in culture, and the ones that were transferred were used as parameters to compare quality of the oocytes in each of the estrogen responders. No significant differences were found in any of them. Abnormal zonae pellucidae are described as possibly due to overmaturation of the follicle. No significant difference in the proportion of abnormal zonae in the different categories was found.
