Fertility Preservation
Fertility preservation refers to obtaining and freezing eggs, sperm, embryos, testicular tissue or ovarian tissue which can then be used to try to have children at a later point in time. The material is stored in liquid nitrogen at -196°C, which suspends any biological activity, and theoretically could be kept forever in that state. Success rates with preserved eggs, sperm and embryos are similar to success rates with ‘fresh’ gametes and embryos in assisted reproductive technology due to advances in this technology over the past decade.
