Risk factors for empty follicle syndrome in assisted reproductive technology with gonadotropin‐releasing hormone agonist trigger
Abstract Purpose To analyze whether response to the GnRH test is a predictor of empty follicle syndrome (EFS) and to analyze independent risk factors for EFS. Methods The GnRH test results of 3765 patients from 2016 to 2018 were used to define the reference range of the GnRH test. Risk factors for E...

| Summary: | Abstract Purpose To analyze whether response to the GnRH test is a predictor of empty follicle syndrome (EFS) and to analyze independent risk factors for EFS. Methods The GnRH test results of 3765 patients from 2016 to 2018 were used to define the reference range of the GnRH test. Risk factors for EFS were estimated by multivariate logistic analysis of 5282 cycles (5247 oocyte‐retrieved cycles with GnRH agonist trigger and 35 cycles of EFS) conducted from 2016 to 2019. Results GnRH testing showed basal hormone values as follows: median LH 5.2 (95 percentile; 1.3–12.6) mIU/mL, LH 30 min 22.0 (6.8–57.1), basal FSH 7.3 (3.0–20.5), FSH 30 min 11.5 (5.1–30.4) and FSH/LH ratio 1.5 (0.6–4.1). Independent risk factors for EFS were antral follicle count (adjusted odds ratio; 0.94, 95% CI; 0.89–0.99), basal LH (0.78, 0.66–0.90), and days duration of ovarian stimulation (1.41, 1.21–1. 60). The respective thresholds were 8 for AFC, 5.0 for basal LH, and 16 days for duration. Conclusions LH 30 min values of the GnRH test did not predict EFS. Independent risk factors for EFS were AFC, basal LH and days duration of ovarian stimulation. |
