IVF Success Rates

Following laboratory improvements, including adopting time-lapse monitoring for all cycles, Galway Fertility Clinic has increased our success rates significantly, to well above the European and Irish averages.

Many factors influence the chances of a successful outcome with IVF. The most important of these is the woman’s age. The quality of the sperm and the quality of the resulting embryos is also vital.

Over 85% of all cycles that are started result in embryo(s) being transferred into the uterus and over half of these would expect to get a positive pregnancy test result.

We are very excited and proud of our latest success rates currently at 78% pregnancy rate per IVF cycle based on all treatment cycles in 2013, where one Blastocyst was selected for transfer up to age 37 years.


Success rates according to female age:

The age of the female partner is an important factor when assessing the chances of success as pregnancy rates decline after 37 years of age. With increasing female age, the ovaries may respond poorly and there is an increased risk of chromosomal abnormalities occurring.

Despite this natural ageing process, fertility treatment can offer an increased opportunity for success with the advances in medication and technologies.

The age of the male partner appears to be much less important factor in achieving a pregnancy, unless the quality of the semen is compromised.

The following graph shows the pregnancy rates according to the female age for all treatment cycles in Galway Fertility Clinic 2013.
Note: results expressed as positive pregnancy test per embryo transfer)


Our overall success rates for 2012-2013 show that 40.6% of all our clients delivered a baby (per IVF cycle for women up to age 41 years). These success rates prove that we are at the forefront of IVF worldwide.

(Note: In keeping with the general population of naturally conceived pregnancies approximately 20-25% of all pregnancies result in miscarriage).
