The control group consisted of 43 women submitted to laparoscopy without a diagnosis of endometriosis.\nResults: Among the patients with endometriosis, we detected nine families with a positive history of endometriosis, comprising one mother, six sisters, three aunts, and two cousins, as opposed to no case among the controls.\nConclusions: These data confirm a familial tendency for endometriosis and suggest that this disorder has a genetic basis.\nSimilar content being viewed by others\nREFERENCES\nRanney B: Endometriosis.
