Patients undergoing COH were prospectively studied in 174 cycles for the presence of baseline ovarian cysts. In 37.4% of all cycles, a baseline cyst > 10 mm mean diameter was found, but a cyst was more common in subsequent cycles than on the first (41.5% versus 15.8%). Cycle fecundity as determined by life table analysis was significantly higher if no baseline cyst were present (0.25 versus 0.06, P < 0.01). These findings suggest that baseline ovarian cysts may adversely affect the chances for pregnancy in COH not associated with IVF or GIFT.
