Success rate of IVF and more on it

IVF is a common word nowadays and everyone is familiar with it. As you all know that it is a process to conceive through artificial fertilisation of the eggs and sperms in a petridish. Special kind of environment is created for the fertilisation to take place. Usually several eggs are allowed to fuse with the sperms to result in one or more embryos. This is done so that you get the healthiest embryo which can be placed inside the uterus. Not every egg that fuses turns out to be healthy and that is why this needs to be done.
