If conventional IVF does not achieve pregnancy, we should know why. However, there is always the possibility of changing gametes: the donation of oocytes, sperm or both. What we see every day is that the uterus is almost always fine. What generates more problems in reproduction are the oocytes, and that is where, if all the above has failed, oocyte donation almost always achieves pregnancy (65% gestation per attempt and 95% in four cycles).
What options does a woman have when she does not achieve pregnancy through IVF?
