Unfortunately, IUI cycles tend to have a lower rate of success than we want, usually in the range of 10-20% per cycle, though it’s standard-of-care to suggest 3-6 IUIs before moving on.
IVF with Intracytoplasmic sperm injection (ICSI) should provide a success rate that is at least 3-4x better. Recent improvements in lab techniques have been shown to lower DNA fragmentation rates to ensure higher fertilization rates in eggs.
But you’re doing the right thing: getting yourself organized before taking this next, important step.
Thyroid control should happen quickly. But the effects of varicocele repair can take 3-9 months….and still not make a difference.
If you really aren’t certain what to do, get a second opinion if you can.
You’re about to embark on a new approach (surgery? IVF? both?). Before doing so, you want to be certain that you’re getting the best advice possible.
