Endometriosis causes infertility through a hostile inflammatory environment that can block tubes, reduce egg quality, and increase miscarriage risk.

“So the reason it's one of the top causes of infertility, yes, your tubes can get blocked. Yes, your egg count and quality can drop. that the environment is so hostile for the sperm, for that little egg that's getting released that needs to be picked up by the tube that can get attacked by these inflammatory cells. The embryo sometimes doesn't form. If it forms, it might get stuck in the tube and you might end up with an ectopic pregnancy or if it goes into the uterus, all that inflammation increases the risk of miscarriage.”
