Objective: to elucidate the impact of ovarian stimulation on the intrauterine milieu represented by the cytokine, chemokine, and growth factor profile in endometrial secretions aspirated before embryo transfer.
Design: prospective cohort study.
Setting: fertility center in tertiary referral university hospital.
Patient(s): forty-two patients undergoing ovarian stimulation with GnRH analogues were recruited. They participated in both a natural and an ovarian-stimulated cycle for within patient comparisons.
Interventions(s): endometrial secretion aspiration was performed immediately before embryo transfer.
Main outcome measure(s): the concentrations of 17 mediators known to be involved in human embryo implantation were assessed by multiplex immunoassay.
Result(s): after correction for multiple testing, significantly higher concentrations of interleukin (IL)-1beta, IL-5, IL-10, IL-12, IL-17, tumor necrosis factor (TNF)-alpha, heparin-binding epidermal growth factor (HbEGF), eotaxin, and dickkopf homologue-1 were present in endometrial secretions obtained in stimulated compared with natural cycles.
Conclusion(s): endometrial secretion analysis provides a novel means of investigating the effect of ovarian stimulation on the intrauterine milieu. The in vivo milieu encountered by the embryo after transfer is significantly altered by ovarian stimulation.
