Statistics from one US clinic show women up to the age of 30 had a 77% success rate after their reversal.
For those between 35 and 39, this rate dropped to 62% and
for those over 40, the success rate was only 34%.
A recent study in Human Reproduction looked at successful rates of delivery of a child after sterilization, comparing reversal of sterilization to IVF (in vitro fertilization).
