These cells are then examined for genetic or chromosomal errors.
This technology remains in its infancy and can be of profound importance
clinically. Hence, couples whose offspring have a high chance of inheriting a
genetic disorder may have their embryos screened. While embryos can have their
sex determined through this procedure, it is illegal in India, except in cases
of sex chromosome-linked disorders.
Embryo screening was recommended to increase implantation rates
in patients with recurrent implantation failure, but it has been established
now, that there is no benefit in this procedure for this indication.
