So, I always assume about 6-8 hours [for sperm to reach the egg]. If you are talking about natural conception (i.e. not IUI), the sperm has to work its way through the cervical [fluid], and much is stored up in the cervical glands (that is how they can stick around for 3 days or more).
There are only around 200 of the white tigers left in the world. White tigers are an Asian species, found from the frozen tundra of the Soviet Far East, south to the humid jungles of Malaya and Indonesia, and west to the hot, hardwood forests of India. There are five living subspecies; three others are already extinct.
White tigers in the wild live to be about 10 to 15 years while tigers in zoos usually live between 16 and 20 years.
