HOW LONG THE SPERM LIVE AFTER BEING THAWED

I am just curious how long that the sperm live in human body after they thawed and used ICI? I have read that they only live 6-24 hours? If this is true then my ICI doesnt now worth then. My doctor inseminate the thawed semen 29 hours prior to the released of the egg. Anybody here got pregnant after 30 hours insimaneted prior to the released of the egg.
