Infertility Treatments - Success Rates.
Treatment's Success Rate:
The success rate of in vitro fertilization and microinjection is obtained by dividing the number of couples who have children with these methods by the number of couples who begin the treatment process. The global success rate of such procedures is approximately 30%. This percentage reflects the average of every age group. However, if patients are divided into groups by age, there is a success rate of 60-70% among young patients between 20-30 years of age, decline by 50% after age 35 and finally dropping to 25% after age 40. The most important cause of this decline is advanced age and egg reserves of reduced quality and quantity. These percentages are representative of the Turkish population as well. In other words, 30 of every 100 couples that begin treatment end up with a child. However, it would be misleading for every patient to use this percentage when evaluating their own condition because the causes of infertility and age are not the same for all patients who receive treatment.
