Understanding success rates

A clinical pregnancy is when we've confirmed that initial positive as being an ongoing pregnancy - determined with a scan between 8 – 12 weeks.

The success rates are also split by age group. The reason for this is that one of the most important factors for success is female age. Unfortunately, as maternal age increases, the chances of success decrease.

The success rate for patients at Sims IVF ranges from 51.3% for patients under 39 years to 25% for patients over 40 years.

To put those figures into perspective, a younger couple in their late twenties or early thirties trying to conceive naturally with no fertility issues would have around 20-25% chance of conceiving on their own each month.
