The risk of permanent infertility after treatment can be avoided by the cryopreservation of sperm before the start of therapy. Embryo cryopreservation is currently an integral part of embryo transfer of in vitro produced bovine embryos. Liquid nitrogen is also used for storage and cryo-preservation of tissue samples.

Cryopreservation may be the only way to store this cell organelle functionally intact for a long period of time. As mentioned above, it was difficult to collect many minke whale oocytes, and viability after cryopreservation was very poor. This is the first quantitative estimate of the mutagenic effect of cryopreservation on the germ line of a metazoan. This opens up the possibility of long-term conservation, by cryopreservation techniques, of the genetic resources of species producing non-orthodox seeds. In the present study, a morphological characterisation is given of organotypic slice cultures after cryopreservation. The first successful pregnancy after cryopreservation was described in 1983 (48). A number of studies into the perinatal outcome of pregnancies after cryopreservation have been reported (35;38;46;50;54;55). Effective cryopreservation of human embryonic stem cells by the open pulled straw vitrification method. However, lower water contents (£20%) are desirable for subsequent cryopreservation, which was the ultimate goal of the present dehydration studies. Mutation during cryopreservation is unlikely to have been important. We think that it is unlikely that these clusters were the result of cryopreservation. One approach to the conservation of germplasm is storage of plant material at ultra-low temperature, a technique known as cryopreservation. Achieving sufficient desiccation of explants is of critical importance in cryopreservation protocols. Cryopreservation of porcine embryos derived from in vitro matured oocytes.
