Abstract		Objective: To test whether the risk of developing clinically significant ovarian hyperstimulation syndrome (OHSS) is related to the number of oocytes retrieved by puncture and the resulting pregnancy and to determine the most suitable cutoff limit of the number of oocytes in predicting OHSS. Study design: The study included 973 patients who underwent ovarian stimulation for in vitro fertilization or intracytoplasmic sperm injection. Using the classification of Schenker and Weinstein; we identified patients who developed moderate and severe OHSS. By multiple logistic regression we established the risk of moderate or severe OHSS development in relation to the number of oocytes retrieved and the resulting pregnancy. A receiver operator characteristic curve was constructed to describe the relation between sensitivity and the false positive rate for the number of oocytes retrieved in the prediction of OHSS. Results: We identified 35 (3.6%) patients who developed OHSS, 8 (0.8%) severe and 27 (2.8%) moderate. (Abstract truncated at 2000 characters)
