The latest craze in IVF clinics in India today is to promote PGT ( preimplantation genetic testing). This is an expensive test, which allows us to check the chromosomes of an embryo, so we can transfer only the chromosomally normal embryos back into the uterus.
Now, logically, this makes a lot of intuitive and scientific sense. After all, what's the point of transferring genetically abnormal embryos into the uterus. And if we have a test which allows us to test whether or not the embryo is chromosomally normal, then doesn't it make sense to use it? Why should we worry about the cost if it improves pregnancy rates ?
Sadly, not only does it add to the costs, it also does not improve success rates, as proven by this paper published in the respected journal, Human Reproduction, in Sept 2018, from one of the world's leasing IVF academic centers in Brussels.
If your doctor pushes you into doing PGT, or suggests that it will improve your chances of getting pregnant, please share this reference with him !
