What is the probability of success of a second IVF?

By Zaira Salvador B.Sc., M.Sc. (embryologist).
Last Update: 11/24/2021

Depending on the cause of the failure of the first IVF attempt, a second attempt may or may not improve the probability of success.

For example, if the failure of the first IVF was due to poor endometrial preparation, the second attempt will change the medication protocol to try to improve this aspect.

Normally, in the second attempt some guidelines are changed to improve the treatment and this usually results in a greater probability of success, although as we have mentioned, it will depend on each situation.
