Abstrakt: A new synergistic approach of classical conservation strategies combined with advanced assisted reproduction technologies (aART) allows for protection and rescue of endangered keystone species at the brink of extinction, which can help to safeguard complex ecosystems. Reproduction biology and management in mammal species is not only challenging in regards to their diverging sizes, anatomy, and often unknown physiology; it also requires customized training or chemical restraint protocols for safe handling. Besides these general challenges, there are several new assisted reproduction techniques (ART) specifically tailored to critically endangered mammals. The current portfolio of ART in these mammalian taxa is ranging from sexual cycle characterization and manipulation, semen collection and cryopreservation, artificial insemination, biobanking of living cells, oocyte collection, in vitro fertilization (IVF), and embryo production, embryo transfer as well as stem cell-derived in vitro gametogenesis for generating gametes in culture. The article covers advanced assisted reproduction technologies (aART), success and challenges, as well as ethical implications.
