The experience with artificial insemination (AI) and the more invasive ARTs (assisted reproductive technologies) in the propagation of non-human primates (NHPs), although limited, has included representation from the Great Apes and both Old World and New World Macaques. The application of these technologies in NHPs is impacted by high cost, substantial technical requirements and the limited captive populations of available animals. A major incentive for their use would be to propagate endangered, underrepresented individuals or valuable founder animals. Detailed protocols and a substantial experience base for the ARTs are available for rhesus and cynomolgus macaques and form the basis of this review, including sperm recovery, processing and long-term storage at low temperatures, insemination techniques and timing. Controlled ovarian stimulation and subsequent oocyte recovery required for the invasive ARTs such as intracytoplasmic sperm injection (ICSI), is also described. Three recent AI reports in Old World Macaques are reviewed, along with examples of the use of the ARTs in the propagation of valuable founder animals, in the preservation of endangered macaques, and finally in the creation of neurodegenerative disease models for biomedical research purposes.
