简介
Objective
To assess the impact of low estradiol (E2) levels in letrozole-stimulated frozen embryo transfer (FET) cycles on pregnancy and neonatal outcomes.
Design
Retrospective cohort.
Setting
University-affiliated fertility center.
Patient(s)
All patients who underwent letrozole-stimulated FET cycles from January 2017 to April 2020 (n = 217). The “Low E2” group was defined as those with E2 serum levels on the day of trigger <10th percentile level (E2 <91.16 pg/mL, n = 22) and the “Normal E2” group was defined as those with E2 serum levels ≥10th percentile level (E2 ≥91.16 pg/mL, n = 195).
Intervention(s)
None.
Main Outcome Measure(s)
Pregnancy outcomes including rates of clinical pregnancy, clinical miscarriage, and live birth. Neonatal outcomes including gestational age at delivery, birth weight, and Apgar score.
Result(s)
The mean ± SD estradiol level was 66.8 ± 14.8 pg/mL for the “Low E2” group compared with …
