Prediction of pregnancy in infertile women based on the American Society for Reproductive Medicine's revised classification of endometriosis.
OBJECTIVE
To estimate the empirical relationship between the revised American Society for Reproductive Medicine's classification of endometriosis and pregnancy rates after treatment.


METHODS
Retrospective analysis.


METHODS
Patients seen by four practicing physicians.


METHODS
Medical and/or surgical therapy for endometriosis.


METHODS
Pregnancy defined as ongoing or delivered.


RESULTS
There were no significant differences in pregnancy rates across stages of endometriosis. There was a slight decline in pregnancy rates among patients with Stage IV endometriosis, but statistical significance was not achieved.


CONCLUSIONS
The use of an arbitrary weighted system for assigning scores to individual categories of disease, or for computing a total score, has limited the overall effectiveness of the classification system to predict pregnancy.
