“…Female giant pandas are in estrus for only a few days each year, so less than 10 percent of giant panda males mate, and less than 30 percent of females conceive naturally [ 2 , 3 ]. Therefore, artificial insemination has become the main practical approach in the captive breeding programs of giant pandas worldwide since it was first attempted in the 1970s [ 4 , 5 , 6 ].…”

As an assisted breeding technique, artificial insemination has become the main effective practical approach in the captive breeding programs of giant panda worldwide. The composition of seminal plasma plays an important role in the success of breeding. The present work is the first attempt to characterize, by proton magnetic resonance spectroscopy (1H-NMR), the metabolome of healthy giant panda seminal plasma. A total of 35 molecules were quantified, with the concentration of 2,3-butanediol being significantly different between individuals younger than 8 years and older than 13 years, and other distinct age-related trends were highlighted by a multivariate analysis. Isopropanol’s concentration was significantly linked to estrus stages. Besides, the variations in the metabolome’s profile during storage were also evaluated. This study may serve as a reference for further research wishing to shed light on the biological mechanisms affecting giant panda sperm’s overall quality and may ultimately lead to novel approaches to giant panda artificial insemination.

“…ARTs include superovulation, cryopreservation of germ cells, artificial insemination (AI), in vitro fertilization (IVF), micro‐insemination (or intracytoplasmic sperm injection; ICSI), embryo transfer (ET), and so on, and it is possible to produce offspring using ARTs in human, primates without human (baboon, rhesus monkey, and cynomolgus monkey), domestic (cat, horse, cattle, pig, sheep, and goat), and laboratory (rabbit, mouse, rat, and hamster) animals . On the other hand, studies on ARTs targeting wild animals have been conducted since around the 1970s and became more active in the 1980s . Thus, various ARTs are indispensable technologies to promote the enormous number of wild and rare animal species, and technical modifications should be made specifically for each species in order to improve the validity of ARTs.…”

Background Microtus genus is one of the experimental animals showing unique characteristics, and some species have been used as various research models. In order to advance the utilization of Microtus genus, the development of assisted reproductive technologies (ARTs) is a key point. This review introduces recent progress in the development of ARTs for Microtus genus, especially Microtus montebelli (Japanese field vole). Methods Based on previous and our publications, current status of the development of ARTs was summarized. Results In M . montebelli , ARTs, such as superovulation, in vitro fertilization, intracytoplasmic sperm injection, embryo transfer, sperm cryopreservation, and nonsurgical artificial insemination, have considerably been established by using the procedures which were originally devised for mice and partly modified. However, when the methods for M . montebelli were applied to Microtus arvalis and Microtus rossiaemeridionalis , all protocols of ARTs except for sperm cryopreservation were technologically invalid. Conclusion Assisted reproductive technologies (ARTs) are considerably established in M . montebelli , and this fact allows this species to be potentially useful as a model animal. However, since ART protocols of M . montebelli are mostly invalid for other species of the Microtus genus, it is necessary to improve them specifically for each of other species.

“…Artificial insemination (AI) is an assisted breeding technique that serves an important role in captive animal breeding programs worldwide [Seager, ; Wildt, ]. This human‐directed method for propagation of captive animals acts as a surrogate in situations when natural breeding is otherwise prohibitive, such as among individuals that do not display appropriate courtship or mating behavior or in the case of unavailable or limited captive populations of healthy breeding males [Howard et al, ; Wildt, ].…”

Factors Affecting the Outcome of Artificial Insemination Using Cryopreserved Spermatozoa in the Giant Panda (Ailuropoda melanoleuca)

Artificial insemination (AI) is an important component of captive breeding programs for endangered species, such as the giant panda. The panda has been the subject of increasingly successful captive breeding programs involving a compilation of assisted breeding techniques, including AI using cryopreserved spermatozoa. AI implementation is currently hampered by a lack of understanding of the factors that may cause failure. We investigated factors influencing the probability of success of AI for 14 giant panda females housed at the China Center for Research and Conservation of the Giant Panda (CCRCGP) inseminated in a total of 20 instances using cryopreserved spermatozoa from 11 males currently residing in 6 different captive breeding institutions. One of the pandas was the oldest giant panda female to ever successfully conceive from AI (20.5 years old). The success of AI was significantly affected by the timing of AI in relationship to both timing of peak urinary estrogen of the female and percent decline in urinary estrogen between the peak level and the first AI attempt. Our results suggest that the window for successful AI in giant pandas may be narrower than previously suspected, although individual differences in rates of decline in urinary estrogen may reflect some degree of variation in this crucial window across females. Our results are consistent with recent research on pandas and other species that demonstrates the efficacy of cryopreserved spermatozoa for AI and highlights the need for more in-depth analysis of factors related to female physiology that may influence its success.
