Examination of fetal growth trajectories following infertility treatment.

Purpose: The objective of this retrospective cohort study was to compare fetal growth during the second and third trimesters for ovulation induction with intrauterine insemination (IUI), fresh embryo transfer (ET), frozen embryo transfer (FET), and spontaneous conception following infertility.

Methods: Three hundred ninety-five women with viable pregnancies confirmed at a single academic fertility center participated. All women achieved pregnancy either by treatment or spontaneously after a diagnosis of infertility.

Blastocyst formation rate for Asians versus Caucasians and within body mass index categories.

Purpose: There are well-documented racial and ethnic disparities for in vitro fertilization (IVF) outcomes, including disparities in clinical pregnancy and live birth rate. Obesity has also been associated with an increase in the risk of infertility and reduction in the efficacy of fertility treatment. However, there are limited data regarding the potential effect of race and obesity on in vitro embryo development.

In vitro fertilization outcomes after fresh and frozen blastocyst transfer in South Asian compared with Caucasian women.

Objective: To study pregnancy outcomes between South Asian and Caucasian women undergoing frozen blastocyst transfer cycles.

Design: Retrospective cohort study.

Setting: Not applicable.
