If a woman has conceived a child before the IVF cycle the success rate increases to 37%. Women in their 20s having 2 or more children have a success rate of 34% in the IVF treatment.
Although the number might be low, research has shown that women who are in their 20s are likely to show more success in their IVF cycle than women who are in their 30s. As the IVF treatment is quite costly women between the age group of the 20s tend to stop the treatment after 1 cycle resulting in a lower numbers of success rate.
