Mouse ascites Golgi mucin expression abnormalities in natural cycle endometrial biopsies predict subsequent in vitro fertilization-embryo transfer (IVF-ET) failure in patients with previous IVF-ET failures.

We performed a double-blinded retrospective cohort study to determine whether endometrial expression of mouse ascites Golgi mucin in a natural, unmedicated cycle predicts subsequent IVF-ET outcome among women with prior IVF-ET failure and poor pre-embryo quality. We found a statistically significant decrease in clinical pregnancy rate among women with abnormal mouse ascites Golgi expression, a test which was found to have high positive predictive value for failed IVF-ET.
