Whether endometriosis causes subfertility or not is also controversial. It is generally accepted that endometriomas cause infertility because severe anatomical distortion must interfere with oocyte pick up. A causal relationship with minimal-mild disease(particularly subtlelesions) is much less certain. Numerous mechanisms have been proposed, including abnormal folliculogenesis, anovulation, luteal insufficiency, luteinized unruptured follicle syndrome, recurrent miscarriage, decreased sperm survival, altered immunity, intraperitoneal inflammation and endometrial dysfunction. However, all these functional disturbances can occur in subfertile women without endometriosis, which suggests that finding disease during investigation for subfertility may be coincidental.
