Back in her 20s, Mrs. AZL had endometriosis. This was when I was learning about and resolving my own immune system issues at the inimitable Environmental Health Center - Dallas".
At the time she was working in a small software company that also had a machine shop, and the chemical odors would waft over from the machine shop. I recommended she find another job. She did, and the endometriosis went away. We have been very careful about our home environment ever since, excluding all petroleum products and anything with added scent.
Hard to say for sure, although I guess it's possible. Both of my sisters had it, and both were told by their respective OB/GYNs that that was the reason they were unable to conceive. However, after surgery, both ended up having children.
Being unfamiliar with such stuff myself, I'm wondering: If endometriosis is an auto-immune disorder, how could surgery correct it?
