Prostaglandin and cytokine levels in pooled peritoneal fluid from infertile patients with histologically confirmed rAFS stage III endometriosis compared with that of fertile patients with no endometriosis at surgery. The pooled peritoneal fluid was added to embryo culture media to model exposure to the in vivo peritoneal fluid microenvironment
