The modern techniques make it possible to preserve large gene materials by freezing sperm or gametes. Sperm freezing, artificial insemination and embryo transfer are routine methods in several domestic species and applications of these techniques may also be used in wild species. However, reproduction physiology is quite species-specific and before any technique can successfully be applied, the main reproduction features like seasonality, estrous cycling, timing of ovulation and fertilization, sperm production and quality etc. must be examined in target species or at least in a nearby relative species. Thus it gives remarkable benefit to research if a domestic and easily available species for experiments exists. By using this type of model species, progress in research is fast and effective and saves the rare endangered individuals from experimental work until the last steps.
