Once the egg is released, or ovulated, it starts to travel down the fallopian tube.

  • Why study the cell biology of fertilization?

  • As the cell biology of mammalian fertilizationbecomes better understood and the molecules that mediate the various steps in the process are defined, new strategies for contraception become possible.

  • What is self-fertilization called?

  • Self Fertilization. The process of fertilization, which involves the cross-fertilization between gametes from two different individuals, male and female, is called allogamy.
