The probability of success of In Vitro Fertilization (IVF) is not a fixed number and can vary depending on several factors. On average, the success rate of IVF is around 30% to 40% per cycle for women under 35, but this number can vary depending on the age of the woman, the quality of the eggs and sperm, and other factors.
For women over 35, the success rate decreases, and for women over 40, it can be significantly lower. Some studies have shown that the success rate of IVF for women over 40 is around 10% to 15% per cycle.
Additionally, the success rate of IVF can also vary depending on the type of fertility clinic or hospital where the procedure is performed. Some clinics have higher success rates than others, so it is important to do research and choose a clinic with a good reputation.
It is also important to note that IVF is not always successful, and there is a risk of miscarriage or other complications. The chance of having a live birth after IVF is around 25% to 30% per cycle.
In summary, the probability of success of IVF depends on several factors, including the age of the woman, the quality of the eggs and sperm, the type of fertility clinic, and other factors. It is important to discuss the potential risks and benefits of IVF with a fertility specialist before undergoing the procedure.
