Typically one to three fresh IVF cycles, but your age and ovarian reserve (egg supply) are obviously major factors. In general, the best results with IVF are up to age 40. Success rates drop each year after 40 and are very low by age 45, using your own eggs. If you have embryos to freeze with a fresh IVF cycle, it can increase your chances of success and lower the number of fresh cycles that you need. Egg donation has high success rates at any age.
