Abstract
This study aimed to evaluate the effects of replacing egg yolk extender with sesame oil on the quality of sperm in goats following incubation at 37°C, chilling at 4°C, and freezing. Semen samples were collected from four intact male goats. The individual semen sample was divided into six groups consisting of a control group and five treatment groups with different egg yolk-to-sesame oil ratios. Seminal plasma was removed, and the sperm pellet was diluted with experimental semen extenders. The control group contained an extender of 10 % egg yolk (SO0), and the experimental extenders were composed of 8.75 % egg yolk and 1.25 % sesame oil (SO1.25); 7.5 % egg yolk and 2.5 % sesame oil (SO2.5); 5 % egg yolk and 5 % sesame oil (SO5); 2.5 % egg yolk and 7.5 % sesame oil (SO7.5); and 10 % sesame oil (SO10). Each group of semen was divided into three groups, incubated at 37°C for 1 h, chilled at 4°C for 4 h, or frozen for 24 h. Five replicates were performed. Sperm quality was evaluated, including motility, viability, and functional membrane integrity. The SO1.25 group achieved the highest sperm quality rate among the treatment groups, and the extender did not have a negative effect compared to the control. However, the total replacement of egg yolk with sesame oil in an extender resulted in the lowest sperm quality. In conclusion, the ratios of egg yolk and sesame oil that were acceptable for goat semen cryopreservation were 8.75 % and 1.25 %, respectively.

Abstract
Cryopreservation is a valuable technique used to assist in the genetic improvement of cultured stocks and provide a continuous supply of good-quality semen for artificial insemination. Conserving semen by cryopreservation serves several purposes (e.g. artificial reproductive technologies and species conservation) and is also used in the clinical treatment of human infertility. However, the lifespan of cryopreserved semen is influenced by a range of factors, including storage temperature, cooling rate, chemical composition of the extender, the concentration of cryoprotectant, reactive oxygen species, seminal plasma composition and hygienic control. The choice of cryoprotectant is a vital factor underlying the success of animal semen cryopreservation. In this regard, extensive research has been carried out on various cryoprotectants, such as egg yolk, dimethyl sulfoxide, methanol, ethylene glycol and dimethylacetamide. Recent studies have also described the use of a range of new cryoprotectants for cryopreservation, including compounds of plant origin (soy), amino acids, antifreeze proteins, carbohydrates and cyclodextrins. Moreover, semen cryopreservation and storage require the use of liquid nitrogen or ultralow refrigeration methods for both long- and short-term storage. This review summarizes the general methods used for freezing semen and discusses the use of traditional and newly emerging cryoprotectants (permeable and non-permeable) for the cryopreservation of semen in selected fish and mammalian species.

Abstract
Cryopreservation of male gametes is one of the most important methods of assisted reproductive technologies, which allows preserving gametes for research or further use. However, the fertilizing ability of spermatozoa after cryopreservation decreases by 30-70%, which makes it urgent to search for new substances with cryoprotective properties. The review considers the main causes of cell damage during cryopreservation. The relevance of methods for assessing the formation of crystals and the physicochemical properties of cryoprotective media depending on various compositions is discussed. The problem of stabilization of the spermatozoa membrane during cryopreservation is considered. A possible solution to the problem of membrane integrity may consist in modification of the basic cryoprotective media with yolk emulsion or development of methods for saturation of the membrane phospholipid layer with cholesterol.

Abstract
To evaluate the effects of four extenders on the post-thaw quality and fertility of goat semen, six Yunshang Black bucks' semen was collected, pooled, diluted with Andromed® (Andr®), Optidyl® (Opt®), P3644 Sigma l-phosphatidylcholine (l-α SL), and skim milk-based (Milk) extenders, and then cryopreserved. The sperm motilities, abnormalities, membrane and acrosome integrity, mitochondrial activity, apoptosis, and reactive oxygen species (ROS) production were evaluated after thawing. After exocervical insemination with the thawed semen, the pregnancy, lambing, and twinning rates were recorded and compared. The results showed that sperm motilities, membrane integrity, acrosome integrity, mitochondrial activity, and viable spermatozoa were significantly higher in the Andr® and Opt® groups than those in the l-α SL and Milk groups (p < .05). Furthermore, there was no difference between Andr® and Opt® (p > .05). The sperm abnormality was lower in semen frozen with the Andr® or Opt® extenders, as compared to the l-α SL or Milk extender (p < .05). Regarding, the viable cells with low ROS production, the optimal results were obtained in the semen frozen with Andr® and Opt® extenders. Following exocervical insemination, the pregnancy and lambing rates in the Milk group were significantly lower than those in the other groups (p < .05). No difference was found in the pregnancy and lambing rates between Andr®, Opt®, and l-α SL (p > .05). Furthermore, the twinning rates were similar between these four groups (p > .05). In conclusion, egg yolk or skim milk can be substituted by soybean lecithin during cryopreservation of goat semen.

Abstract
The aim of this study was to evaluate the effects of 3 different commercially available extenders – AndroMed® (soy lecithin-based), Optidyl® (with the addition of ionized egg yolk), and BULLXcell® (with the addition of fresh egg yolk) – on bull spermatozoa quality, which was evaluated using the parameters of spermatozoa motility, viability, plasma membrane damage, acrosome damage, and mitochondrial activity after thawing and during a 2 h long thermoresistance test. The spermatozoa quality indicators were appraised by computer-assisted semen analysis and a flow cytometer. Significant differences (P < 0.01) between bulls were registered in all indicators measured. The highest average values of spermatozoa total motility and viability were achieved using BULLXcell® extender (44.33%; 52.06%). Variances in comparing this extender with Optidyl® and AndroMed® were −0.83%, −2.64%; −8.33%, −9.51%. The differences found between the egg yolk-based diluents (BULLXcell® and Optidyl®) and AndroMed® were significant (P < 0.01). Therefore, the more valuable extenders for bull semen dilution were egg yolk-based extenders, which provided higher post-thaw spermatozoa survival and quality than the soy lecithin-based extender.

Abstract
The action of substances with non-permeable cryoprotectant potential, besides glucose, has not yet been studied for the species Prochilodus brevis. The objective of this work was to evaluate the action of four non-permeable cryoprotectants on this species sperm cryopreservation. Five pools were cryopreserved in a solution of 5% glucose and 10% dimethyl sulfoxide (Me2SO) associated or not (control) with cryoprotectants egg yolk (5, 10 or 12%), soy lecithin (2.5, 7.5 or 10%), sucrose (5, 10 or 20%) and lactose (5, 8 or 15%). After thawing, samples were evaluated for sperm kinetics (total motility, motility duration, velocities, and wobble - WOB), morphology and membrane and DNA integrity. The treatments containing egg yolk improved significantly (P<0.05) results when compared the control for the membrane integrity parameter. When compared to other treatments, egg yolk, at any concentration, presented higher results (P<0.05) for membrane integrity, total motility, curvilinear velocity (VCL) and average path velocity (VAP) parameters. Egg yolk also showed the best results for WOB, but it did not differ from 5% and 8% lactose and 5% and 20% sucrose. Soy lecithin had the lowest percentages of morphologically normal sperm (P<0.05), while the other treatments did not differ from each other. There was no difference regarding DNA integrity data. Thus, 5% egg yolk is indicated as a non-permeable cryoprotectant for P. brevis, in association with 5% glucose and 10% Me2SO.

Abstract
Bocachico Prochilodus magdalenae es una especie endémica y la más importante de la pesquería continental colombiana. No obstante, sus capturas han disminuido aproximadamente el 67% en los últimos cuarenta años, por tanto ha sido categorizada como vulnerable a la extinción. La criopreservación de semen, es una herramienta biotecnológica de conservación por tanto el objetivo del presente estudio fue evaluar la criopreservación de semen de bocachico con etilenglicol (EG) y leche en polvo descremada (LP). La solución crioprotectora estuvo compuesta por EG (6, 8 o 10%), LP (3, 5 o 7%) y glucosa 6%. La calidad del semen descongelado se evaluó con un software tipo CASA (computer assisted semen analysis). El porcentaje de inclusión de EG, no afectó significativamente ninguno de los parámetros de calidad seminal evaluados (p>0,05), a excepción de la tasa de eclosión (p<0,05); mientras que, la LP afectó significativamente el porcentaje de espermatozoides estáticos (p<0,05) y las tasas de fertilización y eclosión (p<0,01). La mayor movilidad total se obtuvo cuando EG se incluyó a 10% y la LP a 7% (38,4±18,4%) (p<0,05); pero las mayores tasas de fertilización (54,3-64,2%) y eclosión (47,7-57,5%) se obtuvieron cuando EG se incluyó a 6 u 8% y la LP se incluyó a la menor concentración evaluada (3%), sin observarse diferencia significativa entre estos tratamientos (p>0,05). Los resultados permiten concluir que la combinación EG 6% con LP 3% permiten la criopreservación de semen de Prochilodus magdalenae de buena calidad y capacidad fecundante.

Abstract
Background and Aim: Lecithin based diluent such as AndroMed, is a semen diluent made without animal components to prevent the risk of disease transmission, while glutathione (GSH) is an intracellular non-enzymatic antioxidant that prevents cell damage due to reactive oxygen species. Meanwhile, the specific impact of AndroMed and GSH combinations on spermatozoa abnormalities has not been fully studied. Therefore, this study aims to determine the effect of using cauda epididymal plasma-2 (CEP-2) and AndroMed diluents with or without the addition of GSH on the abnormalities of sexing semen of Ongole crossbred bulls in cold storage. Materials and Methods: This study used a factorial completely randomized design 2×2, the first factor was types of diluent and the second was with or without the addition of GSH. Observation of spermatozoa abnormalities was carried out at a storage time of 0-5 days using 297 ejaculations of liquid semen, with 100 spermatozoa observed per smear of each ejaculate. Furthermore, the data were analyzed using a two-way analysis of variance and the significant threshold (p-value) for statistical analysis was set at <0.05. Results: The results showed that there was a significant difference (p<0.05) between AndroMed and CEP-2 in minimizing the abnormalities of upper layer spermatozoa (X), with parameters DH and AD on day 0, damage of spermatozoa (DMR) on days 1-5, and dag-like defect (DLD) on day 5. Furthermore, spermatozoa abnormalities in the lower layer (Y) showed a significant difference between diluents in the parameters of AD on day 1, DMR on days 0-5, and DLD on days 1-5. The significant difference between with or without the addition of GSH in the X sperm was observed in the DH parameters on day 0 and DMR on 5, while there was no significant difference in the Y sperm. Conclusion: Based on the results, AndroMed has the potential to minimize spermatozoa abnormalities compared to CEP-2 diluent in sexed liquid semen. Therefore, AndroMed diluents with or without the addition of 1 mM GSH have no significant effect on spermatozoa abnormalities.

Abstract
Egg yolk is widely used as a cryoprotectant in dog semen extenders, but there is a risk of contamination with animal pathogens. In addition, egg yolk may vary in composition, making it difficult to standardize the extender. Lecithin is an animal protein-free alternative to egg yolk for semen cryopreservation. Recently, it was shown that 1% of soybean lecithin type II-S was better than 2% for freezing canine semen. The aim of the study was to compare two different types of soybean lecithin, with egg yolk as a control. Ejaculates from eight dogs were divided into three equal parts and diluted with a Tris-based extender, containing either 20% egg yolk, 1% soybean lecithin Type II-S or 1% soybean lecithin Type IV-S. The samples were then frozen. Sperm motility was evaluated by computer-assisted sperm analysis (CASA), acrosome integrity (FITC-PNA/PI) and sperm membrane integrity (SYBR-14/PI) post-thaw, as well as after 2 and 4 hr incubation at 37°C. Post-thaw sperm chromatin structure assay and plasma membrane integrity were evaluated by flow cytometry. Total motility, sperm plasma membrane integrity and acrosome integrity were significantly better in the egg yolk extender than in the two soybean lecithin-based extenders. Individual motility post-thaw differed more than in the fresh samples, illustrating individual differences in tolerance to the cryostress. The DNA Fragmentation Index (% DFI) was significantly lower in the Tris egg yolk (TEY) extender compared to any of the soybean-based extenders. The number of high green stained spermatozoa were significantly higher in Type IV-S compared to the control TEY extender. In conclusion, egg yolk was superior to the two lecithin-based extenders to cryopreserve canine semen.

Abstract
The reduction of spermatozoa survival time is a major problem of canine chilled sperm for artificial insemination. The aim of the study was to improve the quality of canine chilled sperm during storage time. We therefore, evaluated the effects of eight treatments with different levels of soybean lecithin concentration (1, 3 and 5%) and egg yolk (20%) in Tris-citric-fructose or Tris-citric-fructose-mineral salts extender on chilled canine sperm quality during 10 days of storage. The sperm motility was analysed by computer-assisted sperm analysis (CASA), whereas plasma membrane integrity, acrosome membrane integrity and mitochondrial membrane potential parameters were determined using a fluorescent staining combination of propidium iodide (PI), Hoechst 33342 (H342), fluorescein isothiocyanate-conjugated Pisum sativum agglutinin (FITC-PSA) and 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolyl-carbocyanine iodide (JC-1) by confocal laser scanning microscope. The results showed that egg yolk was found to be better than soybean lecithin in Tris-citric-fructose or Tris-citric-fructose-mineral salts extender for maintaining the quality of chilled canine sperm within 10 days of storage (P < 0.05). Although egg yolk in Tris-citric-fructose extender could maintain the motility better than other extenders, egg yolk in Tris-citric-fructose-mineral salts extender was the highest in intact plasma membrane, intact acrosome membrane and high mitochondrial membrane potential (P < 0.05). In contrast, the sperm quality of soybean lecithin in Tris-citric-fructose-mineral salts extender was lower than that of soybean lecithin in Tris-citric-fructose extender, and soybean lecithin 1% was greater than soybean lecithin 3% and 5% in plasma membrane integrity, acrosome membrane integrity and mitochondrial membrane potential (P < 0.05). In conclusion, soybean lecithin cannot replace egg yolk in Tris-citric-fructose or Tris-citric-fructose-mineral salts extenders, and egg yolk in Tris-citric-fructose-mineral salts extender is superior to other extenders in chilling canine sperm.

Abstract
Diluents using components of plant origin have been developed as an alternative to animal based extenders for the dilution of bull semen, however, it is unclear if use of these diluents results in in vivo fertility rates similar to those that occur with use of traditional egg yolk-based diluents. The aim of this study was to assess the effect of semen diluent on 60-day non-return rate (NRR) following artificial insemination (AI) with frozen-thawed bull semen. The effect of semen dilution in one of three different commercial diluents (BullXcell - egg yolk-based, OptiXcell - plant-based or AndroMed - plant-based) on post-thaw total and progressive motility as well as kinematic parameters (Experiment 1) and field fertility (Experiment 2, n = 1,480 inseminations) was assessed. Semen stored in OptiXcell had greater post-thaw total and progressive motility than AndroMed (P < 0.05) but did not differ from BullXcell. Semen stored in BullXcell had a greater beat cross frequency and straight line velocity compared to semen stored in AndroMed (P < 0.05) but did not differ when compared with use of OptiXcell; while values for these variables when using OptiXcell and AndroMed did not differ from each other (P > 0.05). There was no difference in any other sperm kinematic parameters (P > 0.05). There was no effect of diluent on 60-day NRR (71.5%, 67.8% and 70.6% for BullXcell, OptiXcell and AndroMed, respectively). In conclusion, while diluent significantly affected post-thaw sperm motility and kinematics, no effect on 60-day NRR was observed. Given that OptiXcell and AndroMed are animal protein-free media these diluents may be a suitable alternative to BullXcell for the storage of frozen-thawed bull semen.

Abstract
The endemic naked carp (Gymnocypris przewalskii Kessler, 1876) plays an important role in the maintenance of the distinctive ecological system of Lake Qinghai at 3.2km altitude on the Qinghai-Tibet Plateau in China. This study aimed to develop a cryopreservation protocol for Gymnocypris przewalskii spermatozoa. Semen was collected from mature individuals during migration and frozen using the liquid nitrogen vapor method. The influence of different cryoprotectants and three extenders on the post-thaw quality of the sperm was analyzed. The highest sperm motility rate and longest motility time after cryopreservation were achieved by combining Ringer's solution with 15% ethylene glycol (P<0.05). The fertilization rate of this cryopreserved semen was 15.26±4.54%. This study thus provides a valuable method for the cryopreservation of the sperm of this important endangered fish species.

Abstract
Egg yolk is usually included in extenders used for preservation of dog semen. Lecithin is an interesting animal-protein free alternative to egg yolk for semen preservation. The aim of our study was to evaluate soya bean lecithin for cryopreservation of dog semen. Five ejaculate replicates were divided in three equal parts, centrifuged and each pellet diluted with one of the three Tris-based extenders containing 20% egg yolk, 1% soya bean lecithin or 2% soya bean lecithin. Extended semen was loaded in 0.5-ml straws, cooled and diluted a second time and frozen in liquid nitrogen vapours. Sperm motility parameters (CASA), acrosome integrity (FITC-PNA/PI) and sperm membrane integrity (C-FDA) were evaluated 5 min post-thaw and after 2 and 4 h of incubation. Total motility was significantly better in the egg yolk extender than in any of the lecithin-based extender and was better in the 1% lecithin extender than in the 2% lecithin extender. Sperm membrane integrity was significantly better in the egg yolk extender than in any of the lecithin-based extenders but did not differ significantly between the 1% and 2% lecithin extenders. Acrosome integrity was significantly better in the egg yolk extender than in the 2% lecithin extender but did not differ between the egg yolk extender and the 1% lecithin extender or between the two lecithin extenders. In conclusion, egg yolk was superior to lecithin in our study. The extender with 1% lecithin preserved sperm motility better than the extender with 2% lecithin.

Abstract
This study was conducted to investigate whether soy lecithin can be used as an alternative cryoprotectant to establish a procedure that does not require the use of egg yolk to cryopreserve rabbit strains. Semen from Japanese White rabbits was frozen with HEPES extender containing 20% egg yolk (EYH), 0.5% (Lec-0.5), 1.5% (Lec-1.5), 2.5% (Lec-2.5), or 3.5% (Lec-3.5; wt/vol) lecithin (type IV-S, ≥30%), and the motility of thawed sperm was analyzed. The sperm motility in the Lec-1.5 group was significantly higher than that in the Lec-2.5 and 3.5 groups and equivalent to the EYH group. From 17 rounds of artificial insemination with frozen-thawed sperm in the EYH and Lec-1.5 groups, 12 rabbits in both groups were pregnant (70.6%) and delivered offspring. The litter size was 3.3 in the EYH group and 5.1 in the Lec-1.5 group. These results indicate that soy lecithin can be used as a substitute for egg yolk as a cryoprotectant on the basis of motility and fertility of the frozen-thawed rabbit sperm and that 1.5% lecithin (type IV-S, ≥30%) in the semen extender was the optimum concentration for rabbit sperm cryopreservation.
