The success rate of IVF (in vitro fertilization) treatment is affected by many factors. Here are the most important ones:
1. Woman's Age
Age is the most important factor affecting IVF success. While the success rate is 60-70% under 35 years old, it drops to 30-40% over 40 years old.
2. Embryo Quality
High quality embryos have higher implantation rates.
3. Uterus Health
A healthy uterine lining provides an optimal environment for the embryo.
