%X To determine if patients with a DC respond similarly to ovarian stimulation when compared to patients without a DC. Infertility patients with a DC that underwent IVF between January 2009 and December 2016 were included. A cystic mass with mixed echogenicity, internal echoes similar to thick bands, fatty-fluid level, or an echogenic tubercle with acoustic shadow (Rokitansky nodule) within two years of the cycle characterized the diagnosis. The z-score compared the standard deviations (SDs) in patients with/without a DC and were compared to a nomogram (expected oocytes minus oocytes obtained divided by the SD), adjusted for age and number of oocytes retrieved, built utilizing cycles from noninfertile female patients. Thirty-nine patients with DC and 7839 patients without DC were identified. The mean number of oocytes (8.6 ± 5.8 vs. 8.5 ± 7.7, p = .43) and MIIs (6.7 ± 4.7 vs. 7.0 ± 6.7, p = .74) retrieved were similar. When cycles with and without a DC were compared to the nomogram (z-score of 0), cycles with a DC presented a z-score for ovarian response of 0.1921 SDs from the mean, and patients without DC presented a z-score of -0.2065 SDs from the mean (similar and less than -1.0). After building a population 'normal' response as a template, patients with and without a DC responded similar to COS.
