I've had 3 failed ivf. what are the chances of working ?

Too Complicated: That depends on the statistics of the center you use, your age, and what other conditions may exist. Your ivf doctor would be best to answer. In a less than perfect world, the usual answer would be about 30%.

Depends: That's a vague question given the limited details. It would depend on a variety of factors - age of woman, etiology of infertility, details of previous ivf cycles (e.g. # eggs retrieved, # of embryos transferred, quality of embryos transferred, etc.), etc. Without those details, difficult to answer accurately.

It depends: The chance for your future success is depends following factors: 1. Your age. If you are young, and you have good ovarian reserve, even with 3 failed ivf, your chance of success is still very good. 2. The causes of your infertility, if you have male factor, tubal disease, ovulation dysfunction, your chance may be still good. 3. The quality of your ivf lab. You may need have second opinion.
