Worrying about the success of In Vitro Fertilisation (IVF) will not improve one's chances of conception. However, most women get nervous and stressed out while undergoing the treatment.

Here is some good news for those who are over-anxious about whether the IVF will be successful. Now there are ways to detect the best embryo, which can rule out chances of an unhealthy embryo being implanted, causing an IVF failure.

Preimplantation Genetic Screening (PGS), a genetic screening test performed on embryo produced during IVF treatment, allows couples to have a healthy baby.

Many patients now use PGS to decide on the best embryo, says Dr Rajni Khajuria, lab director, Igenomix India. ''The PGS test is performed on the embryo before it is transformed. It can significantly increase pregnancy rates per transfer. It also facilitates prospective parents to transfer a single embryo without lowering the chances of conception,'' says Khajuria who was a former researcher at All India Institute of Medical Sciences, New Delhi.

The optional single embryo transfer has many advantages, says Khajuria. Multiple pregnancy can cause more complications and poorer pregnancy outcomes when compared to singleton pregnancy. It could also increase the risk of hypertensive disorders of pregnancy, malpresentation, cord prolapse, premature rupture of the membrane and perinatal death.

PGS is a boon for couples undergoing infertility treatment. Does it allow couples to have designer babies? PGS doesn't give you the option to pick specific genetic traits. It only ensures that your baby does not have any genetic diseases.
