There are several factors that influence IVF success rates. Some of these are described below:
Age is the most important factor for the success of IVF. Patients under 35 years old have the best prognosis. The success rates in women over 43 years are less than 5%..
Antimullerian hormone (AMH) is not a direct factor but does affect the cumulative pregnancy rate. Having a lower AMH does not mean you have a lower success rate for a single IVF attempt. Having a high AMH makes it easier to have a higher cumulative pregnancy rate. The cumulative pregnancy rate is obtained after transferring all the frozen embryos that have been generated from an IVF cycle.
Toxic substances patients who are smokers have a worse pregnancy rate than non-smoking patients.
Weight has been found to be a negative influence on the pregnancy rate.
Apart from these factors, there are numerous studies that indicate that patients following Mediterranean diet have a better outcome in IVF cycles. In addition, moderate exercise has also been shown to improve IVF results.
