IVF should be done at a younger age as the success rate is higher. Patient at their twenties and early thirties have better success rate because at a younger age the quality of oocytes or eggs is better. So, embryo quality is also better. Also, those women experience better implantation of embryos. Once a lady crosses 35 the success rate of IVF declines. Also, beyond 38 and above, the chances of a successful outcome with own egg is minimal. However, in the late thirties and early forties with a poor ovarian reserve, IVF can be successful with ovum donation. Beyond 50 years, ICMR prohibits IVF treatment.
In the USA, the age limit in most IVF programs is 42-45. In women, who are more than 45 years old, the incidence of live birth rate is less than 1 percent. At the age of 50, one can conceive through IVF with a donor egg. However, men and women who have babies at an older age live longer and their children also live longer. ASRM sets a hard line in “Fertility Sterility” that embryo transfer should be strongly discouraged over 50 with underlying issues that could further increase obstetric risk and discouraged in women above 55 without any issues.
