What is In vitro fertilization (IVF)?
IVF (In-vitro fertilization) or test tube baby as it is commonly called is a procedure in which the eggs and the sperms are fertilized outside the body and then transferred back to the womb after 2-5 days.
The process of IVF involves the ovarian stimulation with hormones with the intention of retrieving more eggs. The whole idea is to have enough eggs to produce optimum number of good embryos to transfer and to freeze a few in case the fresh transfer fails. The question here is how many do we actually need ? What is the optimum number of eggs needed to achieve a live birth, which in turn is the ultimate aim of IVF.
