Abstract
The search for assisted reproduction techniques applied to the conservation and even the genetic improvement of wild species is becoming increasingly common. Regarding conservation of male gametes from wild animals, although current advances are focused on cryopreservation, the development of protocols for sperm refrigeration seems to be underrated, despite its various advantages and applications. Therefore, this review aims to highlight the importance of short-term conservation of sperm from wild mammals, report the development of state-of-the-art refrigeration protocols for both ejaculated and epididymal sperm, and evaluate the challenges and prospects of their application.

Abstract
In addition to companion animals and laboratory species, about 270 carnivore species play fundamental ecological roles in different ecosystems. However, almost 40% of carnivore species are now threatened or endangered in the wild because of human activities. While protection of natural habitats is critical, it is equally important to better understand carnivore reproduction, including a solid knowledge in sperm, oocyte, and embryo biology, to maintain sustainable populations in the wild and in conservation breeding centers. Characterizing gamete and embryo biology is also needed to develop cryopreservation and assisted reproductive technologies to enhance conservation efforts. The objective of this review is to provide the most recent knowledge in the biology of sperm cells, oocytes, and early embryos across all carnivore families. Overall, most data originate from populations maintained in breeding centers or zoos. Characterizations of sperm biology and cryopreservation are far more advanced than for oocytes and embryos. Currently, sperm biology is mainly studied in Canids, Felids, Ursids, and Mustelids, with more emphasis on structural than functional properties. Importantly, fundamental studies of gamete and embryo biology in domestic dogs, cats, and ferrets have paved the way for more precise characterizations in wild counterparts as well as the development of cryopreservation and assisted reproductive technologies. A striking feature of spermatozoa across a wide range of Canids and Felids is the presence of teratospermia (>60% of abnormal sperm cells), which is related to the loss of genetic diversity in some populations. Although sperm structures differ across carnivore families, sperm biology remains difficult to compare because of the small amount of data in many species. Regarding oocyte biology and embryology, data are much scarcer than in sperm cells, with too few studies going beyond structural descriptions. More carnivore species and more individuals (especially from wild populations in addition to captive ones) must be studied to improve our understanding about comparative germplasm biology and develop adequate conservation breeding strategies including the use of cryobanking and assisted reproductive technologies.

Abstract
The reproductive physiology of canids is unique compared to other mammalian species. Specifically, the reproductive cycle of female canids is characterized by extended periods of proestrus and estrus followed by obligatory diestrus and protracted ovarian inactivity (anestrus). Although canid reproduction follows this general pattern, studies have shown variations in reproductive biology among species and geographic regions. Understanding of these differences is critical to the development of assisted reproductive technologies including estrus induction, gamete rescue, and embryo production techniques for canid conservation efforts. This review summarizes current knowledge of canid reproduction, including estrus cyclicity, seasonality, and seminal traits, with the emphasis on species diversity. The application of reproductive technologies in wild canid conservation will also be discussed.

Abstract
Since the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, we have established an archive system of livestock and wild animals from the surrounding ex-evacuation zone. Wildlife within the alert zone have been exposed to low-dose-rate (LDR) radiation for a long continuous time. In this study, we analysed the morphological characteristics of the testes and in vitro fertilization (IVF) capacity of cryopreserved sperm of racoons from the ex-evacuation zone of the FDNPP accident. The radioactivity of caesium-137 (137 Cs) was measured by gamma-ray spectrometry, and the measured radioactivity concentration was 300-6,630 Bq/kg in the Fukushima raccoons. Notably, normal spermatogenesis was observed in the seminiferous tubules of the testes, with the germinal epithelium composed of a spermatogenic cell lineage with no evident ultrastructural alterations; freeze-thawing sperm penetration ability was confirmed using the interspecific zona pellucida-free mouse oocytes IVF assays. This study revealed that the chronic and LDR radiation exposure associated with the FDNPP accident had no adverse effect on the reproductive characteristics and functions of male raccoons.

Effect of superoxide dismutase, catalase, and glutathione peroxidase supplementation in the extender on chilled semen of fertile and hypofertile dogs. J Vet Sci 2018; 19:667-675. [PMID: 29649854 PMCID: PMC6167334 DOI: 10.4142/jvs.2018.19.5.667] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2017] [Revised: 03/23/2018] [Accepted: 04/04/2018] [Indexed: 01/27/2023] Open
Abstract
This study investigated the correlation between oxidative stress status and key canine sperm parameters and the effect of addition of a superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) combination in egg yolk tris-citrate glucose (EYT-G) extender on semen during 10 days of storage at 4℃. Ten Boxer dogs were divided into two groups, fertile (F) and hypofertile (H), depending on pregnancy and live birth rate status in the previous year. Semen evaluation was performed on the day of collection (D0) and after 5 (D5) and 10 (D10) days of cooled storage. Sperm motility, kinetic parameters, and DNA integrity were assessed. A correlation between oxidative status and key semen parameters in both F and H groups was observed. Total and progressive motilities were significantly higher in the treated (SOD, CAT, and GPx addition) versus control groups at D10 in both F and H groups, and at D5 in the H group. DNA integrity was significantly higher in both treated groups (H and F) at D5 and D10. In conclusion, the addition of SOD, CAT, and GPx in the extender allows preservation of semen quality for up to 10 days of storage at 4℃ in both fertile and hypofertile dogs.
