Objective: To investigate the benefits of cervical mucous glycodelin-A, granulocyte colony-stimulating factor (G-CSF) and L-selectin levels as a marker of endometrial receptivity in in-vitro fertilization/embryo transfer cycles (IVF-ET). Material and Methods: In this prospective cohort study cervical mucus samples were collected during oocyte pick up and embryo transfer from 56 IVF-ET patients. Blood samples were collected during embryo transfer only. The glycodelin-A, G-CSF and L-selectin levels in cervical mucus and blood samples were measured and the results were compared with the pregnancy rates. Results: Cervical mucus G-CSF and L-Selectin levels measured at embryo transfer were significantly higher than those measured during oocyte pick-up (p=0.04 and p=0.002, respectively). Mean cervical mucous G-CSF levels were significantly higher in pregnant patients compared to non pregnant patients during embryo transfer (p=0.024). When 1365 pg/ml was set as cut-off point for G-CSF levels in predicting pregnancy, sensitivity and specificity were 76% and 61.3%, respectively. However, there were no significant relationship between the glycodelin-A and L-selectin levels in the cervical mucus and pregnancy outcomes. Conclusion: Investigating markers of endometrial receptivity in the cervical mucus during embryo transfer is a novel and non-invasive method in IVF cycles. G-CSF may be an important marker in predicting the implantation. Copyright © 2012 by Türkiye Klinikleri.
