To investigate the impact of elevated serum estradiol (E-2) levels on the day of hCG trigger on the birth weight of term singletons after fresh In Vitro Fertilization (IVF)-Embryo Transfer (ET) cycles.Retrospective cohort study of all patients initiating fresh IVF-ET cycles resulting in live births between January 2004 and February 2013. The incidence of low birthweight (LBW) term singletons in patients with E-2 levels on day of hCG trigger above or below the 95 % cutoff for E-2 values in our clinic (3,069.2 pg/mL) was estimated. Multiple gestations and vanishing twin pregnancies were excluded.Two thousand nine hundred thirty-nine singleton live births were identified for inclusion. One hundred forty seven (5 %) and 2792 (95 %) live singleton births occurred in patients with peak E-2 levels above and below 3,069.2 pg/mL, respectively. The overall incidence of term LBW was 5.4 % in the > 3,069.2 pg/mL group compared to 2.4 % in the a parts per thousand currency sign3,069.2 pg/mL group (P = .038). An E-2 level > 3,069.2 pg/mL on the day of hCG administration was associated with increased odds of LBW term singletons (OR = 2.29; 95 % CI = 1.03-5.11). The increased odds remained unchanged when adjusting for maternal age (aOR = 2.29; 95 % CI = 1.02-5.14; P = .037), gestational age at delivery (aOR = 2.04; 95 % CI = 1.22-3.98; P = .025), and day 3 versus blastocyst transfer (aOR = 2.5; 95 % CI = 1.11-5.64; P = .023).Peak E-2 level > 3,069.2 pg/mL is associated with increased odds of LBW term singletons after fresh IVF-ET cycles. Conservative stimulation protocols aiming not to exceed an E-2 level of 3,000 pg/mL may be advantageous for placentation and fetal growth if a fresh transfer is planned.
