Intrauterine insemination (IUI) - chance of success

Looking at a bar graph about chances of successIt is difficult to assess success rates for intrauterine insemination (IUI) because success depends upon the cause of infertility and whether fertility drugs are used to stimulate egg production.

Discuss with your clinician whether fertility drugs are suitable for you. Usually, it would be reasonable to try three to six IUI treatments. Your clinician will advise what is best for you.

In the year from 01/01/2008 - 31/12/2008, for women receiving IUI with donor sperm, the percentage of cycles started that resulted in a live birth (national average) was:

  • 15.8% (237/1497) for women aged under 35
  • 11.0% (154/1394) for women aged between 35-39
  • 4.7% (23/492) for women aged between 40-42
  • 1.2% (2/172) for women aged between 43-44
  • ** (0/46) for women aged over 44

Figures given in brackets are (IUI cycles resulting in a live birth / IUI cycles started).

If IUI fails after several attempts, depending on your age, your doctor may suggest you try another treatment such as in vitro fertilisation (IVF).

Understanding success rates

Question markWhen choosing a clinic, the statistics should not be the only thing to consider.

Make sure you know what clinical success rates mean before you start analysing them.
