Treatment comparison
Positive Pregnancy and Live Birth Should Be Read Together
You can compare the two separate clinical outcomes for each treatment in the same table.

|---|---|---|---|
| In Vitro Fertilisation (IVF) | 70% | 60% | 35 |
| Egg Donation | 91% | 80% | 42 |
| Sperm Donation | 93% | 76% | 30 |
| Embryo Donation | 92% | 82% | 42 |

Frequently asked questions
Questions about success rates by treatment
IVF, egg donation, sperm donation and embryo donation have different biological starting conditions, gamete sources and patient profiles. The percentages should therefore not be interpreted as a direct quality ranking.
In the treatment-based cumulative data on this page, IVF shows 70% positive pregnancy and 60% live birth. Positive pregnancy and live birth are different clinical outcomes.
These rates represent the recorded cumulative clinical outcomes of the Egg Donation group. A group outcome is not a guarantee of success for an individual patient.
These percentages separately show the recorded cumulative positive pregnancy and live birth outcomes in the Sperm Donation group.
These percentages represent cumulative positive pregnancy and live birth outcomes in the Embryo Donation group. The results are clinical averages for the patient group.
Age is an important factor that can influence outcomes, particularly in treatments using a patient's own oocytes. Showing the average age helps place the rates in the context of the patient profile from which they were derived.
Treatment-specific cards show individual procedure types, while the main IVF and donor groups reflect combined groupings in the source record system. Percentages from different classifications therefore do not have to be identical.
No. Treatment selection should not be based only on the highest clinical percentage. Age, ovarian reserve, sperm findings, previous treatments, genetic requirements and embryological assessment should be considered together.
Different stages occur between positive pregnancy and live birth, so early pregnancy losses and other biological or clinical factors can create a difference between the two rates.
