Cyst aspiration or GnRH antagonist administration for ovarian cysts detected at the start of fresh in vitro fertilization cycles

AbstractThe primary objective of this study is to investigate the effect of transvaginal ultrasonogram (TVUS)-guided cyst aspiration or gonadotropin releasing hormone antagonist (GnRH-ant) administration for the management of solitary ovarian cysts detected at the start of in vitro fertilization (IVF) cycles on the outcomes of the same cycles. This is a single-center, retrospective, cohort study of patients who had TVUS-guided cyst aspiration or GnRH-ant treatment for ovarian cysts detected at the start of IVF during a 5-year period. Four hundred and three patients met inclusion criteria: 41 (10.2%) underwent cyst aspiration and 362 (89.2%) were treated with GnRH-ant. There was no difference in the demographics or baseline IVF cycle characteristics of the two groups. Patients treated with GnRH-ant had a longer duration of ovarian stimulation (10.8 ± 3.45 days versus 9.05 ± 4.06 days, p = 0.003) and required higher gonadotropin doses (3887.7 ± 1097.8 IU versus 3293.7 ± 990.5 IU; p = 0.01) compared with the...
