The probability of success with IVF treatments depends upon a number of factors like the age of the woman, the causes of infertility, the quality of eggs retrieved and the quality of the semen. I do have my IVF experience. The single most consistent variable affecting ovarian reserve is the woman's age. I do have my IVF at the age of 30. In most woman in their 20s about 2/3 of the eggs are genetically normal or balanced. However, there will be some that are genetically abnormal or unbalanced. It appears that the best eggs are ovulated first. The older a woman is, the fewer genetically balanced eggs she has left to respond to fertility drugs. This egg relationship holds true even in the fertile population. At age 35, about 40-50 % of eggs are chromosomally normal. At age 40, about 10-20 % and then much fewer after that. Therefore, in older woman fewer normal embryos are available for implantation into the uterus. Hence, healthy woman over 35 are less fertile than their young counterparts. woman 40 and over may have only a 20% live birth rate with IVF treatment using their own eggs, even though several embryos are placed into the uterus.
