Your Eggs are Not for Research
Though the first IVF baby was born in 1978, the science is still evolving. Hence, some clinics use their patient's eggs for research. This may be done with or without their consent. Even when the patient's consent is taken, it may not always be taken in the right way. Many couples give consent only because they feel that they may be given better treatment if they let the clinic use some of the eggs for research. Some clinics even mislead couples who come to them for treatment by promising a discounted rate for IVF is they give half their eggs for research.
Success Rates are Not Universal
IVF does not have universal success rates. The success rate of couples in their 20s is very different from couples in their 40s. Many clinics do not differentiate between these success rates when they speak to couples. When it comes to success rates, many clinics also fail to differentiate between the conception rate and birth rate. Conception rate refers to the number of cases where the couple successfully conceives through IVF. However, not all of these conceptions result in live births. By only mentioning a conception rate, clinics take advantage of a couple's vulnerability and trust in them to make them believe that they have a higher chance of having a baby than proven.
Sex Determination
The gender of the baby is determined when the embryo is formed. Thus, it is possible to choose the gender of a baby before it is implanted into the mother's womb. The gender of a baby can be found out through a pre-implantation genetic screening (PGS) or pre-implantation genetic diagnosis (PGD). These tests are expensive and actually ethically advised only if one or both parents is a carrier for a genetic disease. In developing countries like India that are already facing a lopsided sex ratio, using these tests to determine the gender of the baby is a major problem.
Thus, do not start the process blindly. Always choose a reputed IVF clinic or hospital for the treatment. The doctors in such a facility will always be transparent with you.
