About 30min to a day: There isn't a official exact time from ejaculation to fertilization, but it's probably a half hour to a day or so. The egg has to be already out there hanging around, waiting for the sperm, in order for the sperm to get there and fertilize it quickly (half hour to half day or so). Otherwise, it can take days to reach an egg, if the egg hasn't even come out of the ovary yet.
