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

The 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 cyst aspiration group. There was no difference in the clinical pregnancy (43.9% versus 41.4%), spontaneous miscarriage (9.76% versus 8.01%) and live birth (34.1% versus 33.4%) rates between the groups. Our findings suggest that cyst aspiration is comparable to GnRH-ant administration for the management of solitary ovarian cysts detected at the start of IVF cycles.
