It's an interesting idea. Pregnancy would give the woman a break from her menstrual cycles, but I've never heard any of the OB/Gyns that I've worked with suggest that as a treatment. The most common treatment for endometriosis is to just put the woman on birth control pills, to regulate her cycles and control the hormones.
Endometriosis is actually considered a fairly common cause of infertility - so actually most people would have
difficulty getting pregnant with endometriosis.
Oh, and endometriosis is when there is endometrial tissue (the stuff that lines the inside of our uteruses and that we shed (bleed) during periods) in places that it shouldn't be - like the ovaries, on the outside of the uterus and inside the abdomen. It usually causes a lot of pelvic pain and heavy, painful periods.
Could get an interesting story out of the idea; if I had more time I'd try to play with it, but alas...
