A Study to Measure Markers of Immune Tolerance to Predict Women at Risk of Miscarriage or Failed Embryo Transfer

Overview

About this study

The purpose of this study is:

Infertility Cohort - To determine if maternal blood concentrations of Gal-9, IL-4, and VEGF-A, -C, -D at the time of embryo transfer in patients undergoing in vitro fertilization are predictive of the cycle outcome: live birth or no live birth

Spontaneous Conception Cohort - To determine if maternal blood concentrations of Gal-9, IL-4, and VEGF-A, -C, -D early in the first trimester of gestation are predictive of miscarriage or live birth.
