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.
As the century drew to a close, only 5,000 to 7,500 were left in the wild, and captive tigers may now outnumber wild ones. Since then, the worldâs tiger population has declined to about 3,200 animals. The South China tiger (P. tigris amoyensis) is the most endangered, with only a few dozen animals remaining. The Malayan subspecies (P. tigris jacksoni), which was determined to be genetically distinct from the Indo-Chinese subspecies (P. tigris corbetti) in 2004, is composed of perhaps 500 individuals.
