How successful is IVF?
The chances of success with IVF are directly related to the age of the woman who provides the egg. Good programs have almost 50% chance of a birth with one cycle when the egg provide is under 35 years of age. Between 35 to 39 years of age the chances drop to approximately 35-40%, while women in their early 40s will have approximately 25% chance of a birth with one single fresh cycle of IVF. Success may be further affected by the condition of the uterus, especially the endometrial lining and also by the number of eggs that are produced, often referred to as the ovarian reserve. The results quoted by clinics will also vary depending on patients medical characteristics and treatment approaches.
