Endometriosis
Surgery is more effective than medicinal intervention for addressing infertility associated with endometriosis. Surgery attempts to remove endometrial tissue and preserve the ovaries without damaging normal tissue. In-vitro fertilization (IVF) procedures are effective in improving fertility in many women with endometriosis.
Thoracic endometriosis
The endometrium, the tissue that normally lines the female uterus, undergoes changes with each menstrual cycle. At the end of each cycle and after the lining has thickened in preparation for hosting a fertilised ovum, it sloughs off, detaches, and is expelled through the cervix and vagina in the process of menstruation. In endometriosis, some endometrial tissue is found in other parts of the body; most often the pelvis and abdomen, the central nervous system, the nasal passages, skin and thorax. At these other 'ectopic' sites, endometrium tissue still responds to hormones with normal cyclical changes - bleeding roughly every 28 days.
