>what actually is the clinical definition of endometriosis? Plainly put, it is when tissue that resembles the uterine lining, or endometrial-like tissue, grows outside the uterus. The tissue can implant itself in nearby tissues, like the ovaries and fallopian tubes, or even more distal organs like the bladder and bowel. ... Over time, these repeated cycles of inflammation and fibrosis may lead to permanent structural changes within the abdomen and pelvis, contributing to chronic pelvic pain and infertility.
i feel like something has been left out. why would uterine lining cells outside the uterus lead to infertility inside the uterus? from this description, I can see all sorts of things going haywire, but it was my impression that the uterine lining was scarred and otherwise rendered infertile for implantation.

The quoted text mentions for example the ovaries themselves, which if damaged can not release eggs, and the fallopian tubes, which if damaged can not transmit eggs from the ovaries to the uterus. These are outside the uterus.
