Researchers are on the way to improving the rate of successful pregnancies from assisted reproductive technology with the development of a technique that has allowed them, for the first time, to check the number of chromosomes in virtually every cell of a test tube embryo.
Full chromosomal analysis has previously been impossible because techniques limited analysis to only a small number of chromosomes in each cell. In most studies, only five of the 24 different types of chromosomes have been tested.
The new technique, published this week, combines whole genome amplification (increasing the amount of …
