COX-2 network as predictive molecular marker for clinical pregnancy in IVF

ABSTRACT: CONTEXT Nowadays, the molecular mechanisms involved in endometrial receptivity and implantation are still not clear. OBJECTIVE The gene expression of human endometrium of patients undergoing an IVF treatment with GnRH antagonists/rec-FSH was studied. CONCLUSIONS COX-2 has been extensively studied as a crucial fertility element in both knock-out mice and human. It appears that increased expression of COX-2 and/or SCGB1D2 on the day of oocyte retrieval in GnRH antagonist/rec-FSH stimulated cycles coincides with a lower probability of achieving a clinical pregnancy in this cycle. Keywords: gene expression analysis, clinical pregnancy in IVF stimulated cycles Endometrial biopsies taken from patients on day of oocyte retrieval in stimulated IVF cycles with 1 or 2 embryos replaced in the same cycle. Gene expression of pregnant patients (n=4) was compared with matched non-pregnant patients (n=4)

The gene expression of human endometrium on the day of oocyte retrieval of pregnant and nonpregnant patients in a stimulated IVF cycle was compared in two independent groups with different GnRH-antagonist ovarian stimulation protocols. The present data suggest that increased gene expression of cyclooxygenase-2, together with the expression of other molecules in the cyclooxygenase-2 network, on the day of oocyte retrieval in GnRH-antagonist cycles coincides with a lower probability of achieving a ...[more]
