Common mistake

Understanding IVF Success Rates

Students often state that IVF has a low success rate without explaining the factors contributing to this, such as age, health of the embryos, and the number of cycles attempted.

Students should include specific factors that affect the success rate of IVF, such as the age of the woman, the quality of the eggs and sperm, and the number of IVF cycles undertaken.
