Fresh versus frozen embryo transfer in women with thin endometrium: a retrospective cohort study.

ABSTRACT:

Background

A thin endometrium affects embryo implantation. We designed a retrospective cohort study to analyze the differences of in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) outcomes between fresh embryo transfer (ET) and frozen ET in patients with a thin endometrium.
