Asian couples undergoing IVF treatment are less likely to have a baby than Caucasian couples, research suggests. The study found people of Japanese, Indian and Chinese origin are 60% less likely to become pregnant than their white counterparts. The research, by the University of California in San Francisco, is based on an analysis of 1,200 couples. It was presented at a meeting of the American Society for Reproductive Medicine in Philadelphia. The research found that Japanese, Indian and Chinese patients undergoing IVF were less likely to get pregnant, and less likely to sustain a pregnancy through to full term. Researcher Dr Karen Purcell, from the University of California in San Francisco, said the difference was staggering.
