IUI vs. IVF: Intrauterine Insemination or In Vitro Fertilization - What to Consider?

Are you curious about whether intrauterine insemination (IUI) or in vitro fertilization (IVF) will help you get pregnant? Attain IVF has the latest info on IUI and IVF success rates.

While there are a variety of factors that can impact your chances of success, including your infertility diagnosis, age will always have a significant impact.

IUI success rates by age

Many times, women will first try IUI because the process takes less time and is less expensive than IVF. However, success rates are also significantly lower.

  • Under 35: 10 to 20% chance of IUI pregnancy success
  • Between 35 and 40: 10% chance of IUI pregnancy success
  • Women 40 and above: 5% chance of IUI pregnancy success

IVF success rates by age

IVF, while more expensive than IUI, offers a better chance of success. Below are 2011 success rates by age group for women using fresh as well as frozen embryos who delivered a baby.

IVF success rates with fresh embryos:

  • Women under 35: 46.2 %
  • Women 35-37: 38.4 %
  • Women 38-40: 27.4 %

IUI or IVF?

Determining which treatment protocol is right for you is a conversation you'll have with your doctor. If you decide to start with IUI, you should have a plan in place about how many times you want to try. Generally, after you've had about three IUI attempts without success, it's time to talk with your doctor about other options with higher success rates, including IVF.
