The doctor will discuss your success rate with you in clinic and recommend how many OI cycles you should consider.
Each time an OI is done the chance of becoming pregnant is between 1 – 30%. This will vary depending on your personal circumstances and will be lower particularly in older women (40 years and over), women with very low egg levels and in women where the quality of the eggs or tubes is not thought to be good.
If both your tubes are blocked there is almost no chance of pregnancy with OI. This is why the clinic will usually ask you to have a tube x-ray before OI treatment. If the sperm quality is poor this also reduces the chances of a pregnancy with OI treatment, which is why a recent sperm test is required before OI treatment is started.
