Epididymal Spermatozoa Stored in a Liquid State. Int J Mol Sci 2022; 23:ijms232314591. [PMID: 36498927 PMCID: PMC9741111 DOI: 10.3390/ijms232314591] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 11/19/2022] [Accepted: 11/20/2022] [Indexed: 11/24/2022] Open
Abstract
The aim of this study was to assess the quality and fertilizing potential of red deer epididymal spermatozoa stored in a liquid state for up to 11 days (D11). In Experiment 1, sperm quality was determined. In Experiment 2, the efficiency of in vitro fertilization (IVF) and artificial insemination (AI) of stored sperm were evaluated. An analysis of sperm quality on D5 of storage revealed a decrease (p < 0.05) in motility and morphology, and a higher proportion of apoptotic spermatozoa. On D1, D7 and D10, the total motility of sperm for IVF and AI was determined to be 82.6%, 71.0% and 64.8%, respectively. The results of IVF and AI demonstrated that the fertilizing potential of spermatozoa differs between days of storage. The percentage of blastocysts was higher when oocytes were fertilized on D1 (17.4 %) compared to D7 (8.5%) and D10 sperm (10.5%). Differences were noted in the pregnancy rates of inseminated hinds. The insemination with D1, D7 and D10 sperm led to live births (33% from D7 and D10). The results indicate that the quality of red deer epididymal spermatozoa remains satisfactory during ten days of storage in a liquid state, and that these spermatozoa maintain their fertility potential.

Abstract
Abstract
Wild ungulates are of fundamental importance for balancing ecosystems, as well as being the species of economic interest. Increasing concern over the accelerated population reduction of these species has resulted in the development of assisted reproduction techniques, such as in vitro fertilization (IVF), as a tool for conservation and multiplication. In the present scenario, IVF protocols were developed based on the methodologies used for domestic ungulates. Nevertheless, owing to the physiological and reproductive differences among the species, several factors associated with IVF and its relationship with the characteristics of the species of interest require clarification. In vitro conditions for the collection and selection of female and male gametes, oocyte maturation, sperm capacitation, co-incubation of gametes, and embryonic development can influence IVF results. Therefore, the present review considers the main advances in the methodologies already used for wild ungulates, emphasizing the strategies for improving the protocols to obtain better efficiency rates. Additionally, we discuss the conditions of each IVF stage, with emphasis on aspects related to in vitro manipulation and comparability with the protocols for domestic ungulates.

Post-mortem recovery, in vitro maturation and fertilization of fallow deer (Dama dama, Linnaeus 1758) oocytes collected during reproductive and no reproductive season.

Abstract
Habitat degradation leads to small and fragmented populations, lower genetic variability and fertility overtime. Assisted reproductive techniques represent important tools to cope with the dramatic loss of biodiversity. Fallow deer (Dama dama), beyond its high commercial value and wide distribution, may represent the most suitable model to study endangered cervids. In this study, oocytes were recovered post-mortem from fallow deer during the breeding and no breeding seasons and were in vitro matured (IVM). The ability of cryopreserved thawed sperm samples recovered by electroejaculation from four adult males was tested by in vitro fertilization of IVM oocytes. The number of oocytes collected per ovary did significantly vary across seasons from 6.2 ± 0.92 during breeding season to 10.4 ± 1.26 during no breeding season (p = .006). Oocytes collected during the breeding season showed higher in vitro fertilization rate compared to the no breeding season (p = .045). However, no embryos reached the blastocyst stage. Semen samples obtained by electroejaculation were successfully cryopreserved, although the cryopreservation process negatively affected most kinetic parameters, mainly at 2 hr post-thawing. Moreover, the percentage of rapid spermatozoa significantly decreased between fresh samples and at 2 hr post-thawing, whereas the percentage of slow spermatozoa increased across the same period (p < .05). Our study provides the logistic steps for the application of assisted reproductive techniques in fallow deer and might be of great interest for genetic resource bank planning.

Potential role of intraspecific and interspecific cloning in the conservation of wild mammals. ZYGOTE 2019; 27:111-117.

Abstract
SummaryIntraspecific and interspecific cloning via somatic cell nuclear transfer (iSCNT) is a biotechnique with great possibilities for wild mammals because it allows the maintenance of biodiversity by recovering species, nuclear reprogramming for the production of pluripotency-induced cells, and studies related to embryonic development. Nevertheless, many areas in cloning, especially those associated with wild mammals, are still in question because of the difficulty in obtaining cytoplasmic donor cells (or cytoplasts). Conversely, donor cell nuclei (or karyoplasts) are widely obtained from the skin of living or post-mortem individuals and often maintained in somatic cell banks. Moreover, the creation of karyoplast–cytoplast complexes by fusion followed by activation and embryo development is one of the most difficult steps that requires further clarification to avoid genetic failures. Although difficult, cloning different species, such as wild carnivores and ungulates, can be successful via iSCNT with embryo development and the birth of offspring. Thus, novel research in the area that contributes to the conservation of biodiversity and knowledge of the physiology of species continues. The present review presents the failures and successes that occurred with the application of the technique in wild mammals, with the goal of helping future work on cloning via iSCNT.

The impact of ovarian stimulation protocol on oocyte quality, subsequent in vitro embryo development, and pregnancy after transfer to recipients in Eld's deer (Rucervus eldii thamin). Theriogenology 2016; 91:134-144. [PMID: 28215678 DOI: 10.1016/j.theriogenology.2016.12.021] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2016] [Revised: 12/17/2016] [Accepted: 12/21/2016] [Indexed: 11/22/2022]
Abstract
Propagating genetically valuable individuals through oocyte collection, in vitro fertilization (IVF) and embryo transfer is critical to maintain sustainable populations of the endangered Eld's deer. The objectives of this study were to assess the impact of exogenous FSH injections on (1) the number and in vitro competence of oocytes collected and (2) the developmental potential of resulting IVF embryos after transfer into recipients during the breeding season (February-April). In a pilot experiment, estrus synchronization was conducted in three surplus females (using intravaginal progesterone-releasing devices, CIDRG for 14 days and injections of buserelin (a GnRH agonist). Five days after CIDR removal, ovaries were excised, minced and a total of 133 oocytes were recovered. Following in vitro maturation (IVM) and IVF, 63% of the oocytes formed embryos but only 5% reached the blastocyst stage. In a subsequent study, follicle numbers and diameters were compared between synchronized does stimulated with 0 or 80 mg FSH (-FSH and +FSH; n = 8 does in each group) and oocytes collected either by laparoscopic ovum pick-up or ovariectomy. FSH stimulation increased the main follicular diameter from 2-3 mm to 4-5 mm (P < 0.05) but not the oocyte number (∼20/donor) or the percentage of good quality oocytes (57%) regardless of the treatment. FSH stimulation did not either affect the percentage of cleaved embryos after IVF (25-35%; P > 0.05). Lastly, embryos at the 2-to 8-cell stage (from either + FSH or -FSH groups) were transferred into the oviducts of 11 synchronized recipients. With the +FSH embryos, three pregnancies failed between 90 and 120 days of gestation and two fawns that were born preterm (Days 215 and 224 of gestation) died at birth. In the -FSH group one healthy female fawn was born on Day 234 of gestation. This is the first report of a successful in vitro embryo production and subsequent birth of a live Eld's deer fawn. Further investigations are required to improve IVM/IVF success and the developmental potential of the embryos.
