**5. Conclusion**

With the dramatically accelerated species extinction rate we see in recent decades, it is our obligation to seek any possible venue to bring this biodiversity loss to a halt and, while

attempting to do so, to seek ways to safe-keep gametes, embryos and somatic cells from (ideally) all species on Earth. To our great disadvantage from a cryobiologist standpoint, species are different from each other and preservation techniques almost invariably require species-specific customization. As was discussed here, there are many options for 'putting life on hold'. Cryopreservation is by far the most advanced and widely used technique that has lead to the establishment of several genome resource banks. Within cryopreservation, slow freezing currently holds the leading role but at least for oocytes, and slowly for embryos too, vitrification is gradually replacing it to become the cryopreservation technique of choice. Due to its small size, condensed DNA and little cytoplasm, spermatozoa are relatively easy to cryopreserve and this was already done in hundreds of species. Oocytes and embryos are much more difficult to obtain in large enough numbers to develop the needed protocols and, because of their large size, more difficult to cryopreserve. It is thus not surprising that oocytes or embryos of only a handful of wildlife species have been cryopreserved. An array of other options, including gonadal tissue and whole gonads cryopreservation, freeze-drying of spermatozoa and somatic cells, SCNT and ISCNT, to name just a few, are largely in the developmental or experimental stage and, if matured and improve in efficiency, they hold great promise and will become highly attractive to wildlife conservation and other fields concerned with 'putting life on hold'. These techniques will not replace the basic and well studies equilibrium freezing and vitrification but will help in supporting them as well as in handling cases in which routine cryopreservation cannot be done. While waiting for these and future technologies to mature and improve in efficiency we should strive to preserve whatever we can – gametes, embryos, gonadal tissue, whole gonads, somatic cells, and stem cells – anything we can. Such collections should be from sufficient number of representatives of each species so that we will be well prepared in the unfortunate event that a need will arise. As Benirschke (1984) put it: 'You must collect things for reasons we don't yet understand.'

The techniques used in assisted reproduction for wildlife or domestic animals are similar, and consist in the collection, evaluation, and cryopreservation of semen; artificial

Considering that the maintenance of genetic diversity is reproduction dependent, reproduction technologies are important tools for the preservation of endangered species, throught the development of methods to increase the fertility in these animals (Howard, 1993). Several studies show that hormone therapies may induce ovulation and/or superovulation in wild animals (Pope, 2000). The artificial induction of ovulation and superovulation are important components in assisted reproduction techniques, especially in cats, because their

According to The Word Zoo Conservation Strategy ([IUDZG/CBSG], 1993), some of the many benefits from using assisted reproduction techniques in conservation management

1. To enable the exchange of genetic material between two or more zoos collaborating in the same program, including animals in captivity and in the wild. Semen transportation is economical and reduces the risks involved in animal transfers and consequently

2. To enable reproduction in animals with physical and reproductive behavioral disabilities. This is important for animals that are representative of genetic lines that

3. To enable rapid population growth when only a small founder population is available; 4. To assist in maintaining the ratio between males and females by selectively
