For this specific method of cryopreservation, oocytes are collected directly after an animal is castrated or deceased and immediately frozen at -196°C in liquid nitrogen. This technique allows the storage of oocytes of valuable animals for an unlimited time, so that they can be used to produce offspring with the help of assisted reproduction techniques. The aim is to further improve and apply these methods to save highly endangered species such as the Asiatic lion from extinction. The current research on African lions as a model species is an important step in this direction. The results are reported in the scientific journal ....

Researchers produce first African lion in-vitro embryos after vitrification of immature oocytes
A team of scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Germany, Givskud Zoo - Zootopia in Denmark and the University of Milan in Italy succeeded in producing the very first African lion in-vitro embryos after the vitrification of immature oocytes. For this specific method of cryopreservation, oocytes are collected directly after an animal is castrated or deceased and immediately frozen at -196°C in liquid nitrogen.
