El Kamouh M, Brionne A, Sayyari A, Laurent A, Labbé C. Cryopreservation effect on DNA methylation profile in rainbow trout spermatozoa. Sci Rep 2023; 13:19029.

Abstract
Spermatozoa are the cells that are most commonly used for cryopreservation of valuable genetic resources in aquaculture. It is known that fish spermatozoa transmit to the embryo not only their genetic but also their epigenetic profile, especially DNA methylation. Therefore, any alteration of the DNA methylation profile in spermatozoa induces the risk of transmitting epigenetic alterations to the offspring. The aim of this study was to assess the effect of cryopreservation on DNA methylation in rainbow trout spermatozoa. To trigger variable cellular response after freezing-thawing, spermatozoa from mature males were cryopreserved with dimethyl sulfoxide, methanol or glycerol as cryoprotectant. We observed that dimethyl sulfoxide was the best to preserve thawed spermatozoa functions. Methanol only slightly preserved all the cellular parameters, while glycerol failed to protect motility and fertilization ability. The consequences on DNA methylation were assessed using Reduced Representation Bisulfite Sequencing (RRBS). Sperm cryopreservation did not thoroughly impact DNA methylation, although 335-564 differentially methylated cytosines were characterized depending on the cryoprotectant. Very few of them were shared between cryoprotectants, and no correlation with the extent of cellular damage was found. Our study showed that DNA methylation was only slightly altered after sperm cryopreservation, and this may render further analysis of the risk for the progeny very challenging.

Du C, Zheng X, Jiang J, Meng J, Wu Y, Gao X, Zhu J. The effects of extenders, cryoprotectants and conditions in two-step cooling method on Varicorhinus barbatulus sperm. Cryobiology 2021; 100:133-141. [PMID: 33640316 DOI: 10.1016/j.cryobiol.2021.02.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Revised: 02/02/2021] [Accepted: 02/22/2021] [Indexed: 11/25/2022]
Abstract
In this study, we developed an optimal cryopreservation procedure for Varicorhinus barbatulus sperm. To this end, we optimized (1) the types and dilution ratios of extenders; (2) types and final concentration of cryoprotectants; and (3) freezing conditions, including equilibration time, height above the surface of liquid nitrogen (LN), and the cooling times in the two-step cooling method. The optimum result was obtained when the sperm was diluted at a 1:9 ratio in D-17 with 10% methanol, equilibrated at 4 °C for 10 min, held at 7 cm above LN for 2 min, and finally stored in LN. After storage for 12 h in LN, the sperm was thawed in a water bath at 40 °C for 6s, the post-thaw sperm motility was 66.10 ± 7.12%, while the corresponding rate for fresh sperm was 87.08 ± 2.38%. Using computer-assisted sperm analysis, we found a significant decrease in the motility parameters of post-thaw sperm, especially the parameters related to velocity. To evaluate the effects of cryopreservation on the structural integrity of sperm, transmission electron microscopy and scanning electron microscopy were employed, which showed the defects in frozen sperm, including: abnormal heads, damaged plasma membranes, broken tails, and the disappearance of the mitochondrial internal crest. In addition, we determined the mitochondrial membrane potential to assess the functional integrity of frozen sperm. Our results showed a decrease in the mitochondrial function of frozen sperm. This procedure could be used alongside cryopreservation of V. barbatulus and supports its commercial-scale production and species conservation.

Semen cryopreservation for the Mediterranean brown trout of the Biferno River (Molise-Italy): comparative study on the effects of basic extenders and cryoprotectants. Sci Rep 2019; 9:9703. [PMID: 31273238 PMCID: PMC6609640 DOI: 10.1038/s41598-019-45006-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Accepted: 05/09/2019] [Indexed: 12/03/2022] Open
Abstract
This study was designed to optimize the semen freezing protocol of the native Mediterranean brown trout inhabiting the Molise rivers through two experiments: an in vitro analysis of the effects of two basic extenders combined with three cryoprotectants on post-thaw semen quality; and an in vivo test to assess the fertilization and hatching rate. Semen was diluted at a ratio of 1:3 in a freezing medium composed of a glucose extender (A) or mineral extender (B). Each basic component contained 10% dimethylsulfoxide, dimethylacetamide or methanol. The post-semen quality was evaluated considering motility, duration of motility, viability and DNA integrity. The basic extender and cryoprotectant were shown to have significant effects on these variables, and the best results were obtained using extender A or B combined with dimethylsulfoxide (P < 0.05). These freezing protocols were selected for fertilization trials in vivo. Fertilization and hatching rates were significantly higher in fresh semen. No significant differences were observed in frozen semen using extender A or B, although higher percentages of eyed eggs and hatching rates were recorded using extender A. According to our in vitro and in vivo results, the glucose-based extender and dimethylsulfoxide emerged as the best combination for an effective cryopreservation protocol for semen of this trout.

Abstract
Simple Summary Cryobanking is an important tool to preserve the genetic resources of fish species. Semen cryopreservation has been extensively used in conservation programs for endangered species. Here, we aimed to find an effective cryopreservation protocol for the autochthonous Mediterranean brown trout inhabiting the Biferno river (south Italy), in order to create a sperm cryobank. Low-density lipoproteins and sucrose were tested as non-permeating cryoprotectants (NP-CPAs) to replace the egg yolk. Moreover, the thawing rate (10 °C for 30 s vs. 30 °C for 10 s) was also studied. From results obtained in vitro and in vivo, egg yolk emerged as the best NP-CPA and the lower thawing rate recorded better post-thaw semen quality in vitro and higher fertilization and hatching rates in vivo. These findings are important because they will contribute to the creation of a sperm cryobank for Molise’s native trout, which is a milestone of our European project (Life Nat.Sal.Mo). Abstract The aim of our study was to test the effects of different non-permeating cryoprotectants (NP-CPAs), namely low-density lipoproteins (LDLs), sucrose, and egg yolk, and thawing rates on the post-thaw semen quality and fertilizing ability of the native Mediterranean brown trout. Pooled semen samples were diluted 1:3 (v:v) with 2.5%, 5%, 10%, or 15% LDL; 0.05, 0.1, or 0.3 M sucrose; or 10% egg yolk. At the moment of analysis, semen was thawed at 30 °C/10 s or 10 °C/30 s. The post-thaw semen quality was evaluated, considering motility, the duration of motility, viability, and DNA integrity. Significantly higher values of motility and viability were obtained using egg yolk/10 °C for 30 s, across all treatments. However, LDL and sucrose concentrations affected sperm cryosurvival, showing the highest post-thaw sperm quality at 5% LDL and 0.1 M sucrose. Based on the in vitro data, egg yolk, 5% LDL, and 0.1 M sucrose thawed at 10 °C or 30 °C were tested for the in vivo trial. The highest fertilization and hatching rates were recorded using egg yolk/10 °C (p < 0.05). According to these in vitro and in vivo results, egg yolk emerged as the most suitable NP-CPA and 10 °C/30 s as the best thawing rate for the cryopreservation of this trout sperm, under our experimental conditions.

Abstract
This works studies the physiological characteristics (sperm motility characteristics) and biochemical characteristics (DNA damage, enzymes activities and fertilization ability) of fresh and freeze-thawed semen of sex-reversed female mandarin fish Siniperca chuatsi (n = 30) obtained with the application of 17α-methyl testosterone for sex reversal. The fresh sperm motility and fertilization rate of sex-reversed females were about 83% and 70% respectively which had no significant difference with normal males (p > 0.05). Except for the value of DNA damage, other values of sperm motility, related enzymes activities and fertilization rate of sex-reversed female sperm declined after a process of cryopreservation (p < 0.05). But the frozen sperm can still get nearly 60% of the fertilization rate. This study identified the physiological and biochemical characteristics of the fresh and cryopreserved sperm from sex-reversed female mandarin fish, and the sex-reversed female spermatozoa can be used for actual production.

Abstract
The applicability of a programmable freezer for the increased-scale cryopreservation of common carp sperm was investigated. The effect of different equilibration times, cryopreservation methods, extenders, dilution ratios, activating solutions on the post-thaw motility of common carp sperm was investigated. The suitable post-thaw storage time-interval as well as fertilizing capacity of cryopreserved sperm was also examined. The motility, curvilinear velocity (VCL) and straightness (STR) values did not decrease significantly during 60min of equilibration neither in equilibrated nor thawed groups. Motility parameters of thawed sperm were similar using a conventional cryopreservation technique using a polystyrene box [motility (33%), VCL (47μm/s) and STR (88%)] and a programmable freezer: [motility (32%), VCL (54μm/s) and STR (89%)]. The highest motility and VCL was measured with a sugar based extender (grayling extender) at a ratio 1:9 (motility: 52%, VCL: 76μm/s) and 1:20 (motility: 49%, VCL: 76μm/s). The activating solution for cyprinids (ASC) could prolong sperm movement up for 2min. A storage time of six hours following thawing did not have a significant effect on the motility parameters of thawed carp sperm. Agglutination was observed during cryopreservation of an elevated volume of sperm whereas motility 47%, VCL 62μm/s and STR 91% were measured after thawing. Fertilization rate with thawed sperm (32%) was significantly lower compared to the control group (73%). According to our results, the developed method using a programmable freezer is suitable for the cryopreservation of elevated number of straws. However, carp sperm agglutination during freezing may have a negative effect on the fertilizing capacity.

Abstract
The goal of this study was to develop a simple glucose-methanol extender for cryopreservation of Siberian sturgeon (Acipenser baerii) semen. Semen quality was assessed by determining post-thaw sperm motility and fertilizing ability at hatching stage. We tested the effect of glucose concentration (0, 0.10, 0.15, 0.20 and 0.30 M) in a methanol extender on post-thaw sperm motility. Sperm motility parameters and fertilizing ability of semen cryopreserved in 0.1 M glucose in 15% methanol (GM) were compared to previously described Tris-sucrose-KCl in 10% - methanol extender (TSKM). Additionally, sperm motility and fertilizing ability in relation to 30 min equilibration in GM extender before cryopreservation and 30 min of post-thaw storage were determined. The beneficial effect of the glucose for semen cryopreservation was related to its concentration with a quite narrow optimum of 0.1 to -0.15 M. The fertilization rates of frozen/thawed sperm were similar for both (TSKM and GM) tested extenders. The sperm motility and fertilization rate were not affected either by 30 min equilibration in GM extender or by 30 min of post-thaw storage. Our work indicates that the use a simple extender consisting of 0.1M glucose in 15% methanol can be an alternative cryopreservation method to those previously described for sturgeons. The use of an equilibration period and the possibility of post-thaw semen storage can improve organization of hatchery work and help with logistics of large-scale hatchery operations.

Abstract
SummaryThe quality of fish gametes, both male and female, are determined by several factors (age, management, feeding, chemical and physical factors, water quality, etc.) that have an impact on the survivability of embryos, larvae and/or fry in the short or long term. One of the most important factors is gamete ageing, especially for those species that are unable to spawn naturally in hatcheries. The chemical and physical factors in hatcheries and the nutrition that they provide can significantly alter harvest quality, especially from females; as a rule, males are more tolerant of stress conditions produced by inadequate feeding, management and/or poor water conditions. The stress produced on broodstock by inadequate conditions in hatcheries can produce adverse effects on gamete quality, survival rates, and the embryonic eggs after hatching.

Abstract
The present study focused on development of a sperm cryopreservation protocol for the critically endangered olive barb Puntiussarana (Hamilton, 1822) collected from two stocks within Bangladesh and reared in the Fisheries Field Laboratory, Bangladesh Agricultural University (BAU). The sperm were collected in Alsever's solution prepared at 296mOsmol kg(-1). Sperm were activated with distilled water (24mOsmol kg(-1)) to characterize motility. Maximum motility (90%) was observed within 15s after activation, and sperm remained motile for 35s. Sperm activation was evaluated in different osmolalities and motility was completely inhibited when osmolality of the extender was ≥287mOsmol kg(-1). To evaluate cryoprotectant toxicity, sperm were equilibrated with 5%, 10% and 15% each of dimethyl sulfoxide (DMSO) and methanol. Sperm motility was noticeably reduced within 10min, when sperm were equilibrated with 15% DMSO, indicating acute toxicity to spermatozoa and therefore this concentration was excluded in further trials. Sperm were cryopreserved using DMSO at concentrations of 5% and 10% and methanol at 5%, 10% and 15%. The one-step freezing protocol (from 5°C to -80°C at 10°C/min) was carried out in a computer-controlled freezer (FREEZE CONTROL® CL-3300; Australia) and 0.25-ml straws containing spermatozoa were stored in liquid nitrogen for 7-15days at -196°C. The highest motility in thawed sperm 61±8% (mean±SD) was obtained with 10% DMSO. The fertilization and hatching rates were 70% and 37% for cryopreserved sperm, and 72% and 62% for fresh sperm. The protocol reported here can be useful for hatchery-scale production of olive barb. The use of cryopreserved sperm can facilitate hatchery operations, and can provide for long-term conservation of genetic resources to contribute in the recovery of critically endangered fish such as the olive barb.

Abstract
Sperm proteins in the seminal plasma and spermatozoa of teleostean and chondrostean have evolved adaptations due to the changes in the reproductive environment. Analysis of the composition and functions of these proteins provides new insights into sperm motility and fertilising abilities, thereby creating possibilities for improving artificial reproduction and germplasm resource conservation technologies (e.g. cryopreservation). Seminal plasma proteins are involved in the protection of spermatozoa during storage in the reproductive system, whereas all spermatozoa proteins contribute to the swimming and fertilising abilities of sperm. Compared to mammalian species, little data are available on fish sperm proteins and their functions. We review here the current state of the art in this field and focus on relevant subjects that require attention. Future research should concentrate on protein functions and their mode of action in fish species, especially on the role of spermatozoa surface proteins during fertilisation and on a description of sturgeon sperm proteins.

Abstract
In seminal plasma of the rainbow trout 12 proteins were detected by SDS-PAGE, ranging in their molecular weight from 135 to 16 kDa. Only those proteins with a molecular weight of 65, 54, 47 and 16 kDa occurred in all investigated seminal plasma samples. The 65 and the 54 kDa protein were found in highest quantities (34-45% of the total quantified protein content) followed by the 47 and the 16 kDa protein (6-7% of the total quantified protein content). The 65 and the 48 kDa protein were glycoproteins as they stained positively with Periodic-Acid-Schiff reagent (PAS) specific for carbohydrates as well as with Coomassie Blue. The 90 and 19 kDa protein were found in 82-91% of the investigated samples, all other proteins in lower frequencies of 36-73%. Seminal plasma contained no lipoprotein as staining with Sudan black B was negative. To find out which proteins positively affected the sperm viability (defined as sperm motility which could be activated) spermatozoa were incubated in sperm motility inhibiting saline solution containing different seminal plasma protein fractions. Sperm motility which could be activated after an incubation period of 48 h was highest in those fractions which shared the 54, 47, and the 16 kDa protein. When spermatozoa were incubated in untreated seminal plasma sperm viability was still higher than in the seminal plasma protein fractions indicating that other components of the seminal plasma positively affected sperm viability, too. The possible influence of seminal plasma proteins on sperm physiology is discussed.

Abstract
Sperm cryopreservation protocols have been developed for live-bearers such as the green swordtail Xiphophorus helleri and the platyfish Xiphophorus couchianus. Despite the high post-thaw motility (~75%) obtained in both species, the requirements of sperm storage within the female reproductive tract coupled with the process of internal fertilization place functional demands upon cryopreserved sperm samples far beyond those of oviparous species. The purpose of this study was to facilitate the artificial insemination process with cryopreserved sperm of X. helleri through evaluation of parameters related to sperm quality after thawing. Specifically, this study evaluated the effects on motility for fresh and thawed sperm samples of centrifugation (for concentration of sperm and washing for removal of cryoprotectant), ionic composition, and additions of glucose and fetal bovine serum (FBS) in extender solutions. Centrifugation at 1000 ×g for 10 min at 4 °C was found to have no adverse effects on sperm motility of fresh samples, and for cryopreserved samples, the removal of glycerol by washing yielded higher and longer post-thaw motility (e.g., 168 h vs. 48 h for the controls). Suspension of fresh sperm samples in magnesium-free Hanks' balanced salt solution (HBSS) did not affect motility; however, HBSS prepared with the absence of potassium or calcium, and the use of unsupplemented saline (NaCl alone) as extenders significantly reduced sperm motility. The presence of glucose in HBSS yielded higher and longer motility for fresh and thawed samples, but addition of glucose at greater than 2 g/L were unnecessary. Addition of 20% FBS prior to freezing was found to increase the post-thaw motility significantly compared to control treatment with 14% glycerol alone. Also addition of 20% FBS after thawing and centrifugation was found to induce the formation of sperm bundles, which may be beneficial for internal fertilization success. In conclusion, concentration of sperm and the removal of cryoprotectant (through centrifugation), and the addition of 20% FBS in the extender is recommended for future insemination trials with cryopreserved samples.

Abstract
The customary dilution of boar semen for subsequent artificial insemination (AI) procedures damages the cell membrane of spermatozoa, resulting in a loss of enzymes and other cytoplasmic contents and acrosomal reactions. We encapsulated non-diluted boar semen in barium alginate membranes to optimize AI procedures and to improve the functional integrity of spermatozoal membranes during storage. The percentage of non-reacted acrosomes (NRA) and measurements of enzyme leakage (cytochrome c oxidase (COX), lactate dehydrogenase (LDH), and glucose-6-phosphate dehydrogenase (G6PDH)) were used as indices of the functional status of diluted, unencapsulated and encapsulated spermatozoa, stored for 72 h at 18 degrees C. Enzymatic activity was assessed in situ by microdensitometry, and non-reacted acrosomes were microscopically determined by staining. The percentage of acrosome integrity and the intracellular enzymatic activities during storage were different for unencapsulated and encapsulated semen. Semen dilution caused a rapid decline in enzymatic activities and concomitant acrosomal reactions. Encapsulated spermatozoa had significantly higher acrosome integrity (77% versus 55%; P < 0.01 after 72 h) and an overall higher in situ enzymatic activity. For cytochrome c oxidase and lactate dehydrogenase the greatest differences between encapsulated and unencapsulated spermatozoa were present after 72 h whereas for glucose-6-phosphate dehydrogenase significant differences were found within 24h of storage. The encapsulation process maintains a better preservation environment for boar spermatozoa and could be a promising, innovative technique to improve storage of these cells.

Abstract
In addition to producing homozygous lines for biomedical and genomic research and monosex stocks for commercial purposes, androgenesis is the biotechnology considered most promising and reliable for recovering complete nuclear genome information from cryopreserved fish cells. That is because procedures of cryopreserving spermatozoa, contrary to procedures for oocytes or entire eggs, are being well developed. Application of androgenesis in genome banking programs addresses the needs of both the aquaculture industry (safeguard for valuable strains and lines) and natural resource conservation (in vitro protection of endangered species or populations). The present study was focused on successful production of an androgenetic rainbow trout stock using cryopreserved spermatozoa. Our report constitutes the first time a full factorial analysis of processing and biological factors affecting androgenesis efficacy has been presented. Also for the first time, the survival of androgenetic individuals during 2 years of life was recorded. Remarkably high survival rates were observed in one of the two experiments-up to 42.5 +/- 2.8% of hatched larvae, 22.5 +/- 0.1% of swim-up larvae and 10.5% of androgenetic alevins 0.4 g. Mortality rates in androgenetic groups were high especially during the first 6 months. In all, 114 androgenetic individuals (0.9%) survived 2 years. Cryopreservation of spermatozoa generally did not affect androgenesis efficiency significantly, however, this effect was significantly dependent on the method of ploidization shock and on the duration of treatment. Significant interactions were revealed between the irradiation dose and the magnitude of pressure applied, and between the treatment of sperm and duration of pressure shock. Individual variability of spermatozoa donors significantly affected androgenesis efficiency regardless of their genetic (outbred or inbred) origin. Genetic source of the oocytes, contrary to spermatozoa, proved to be an important factor. Following findings of other researchers that androgenesis using cryopreserved spermatozoa is possible, we demonstrated that viable stock could be successfully established from cryopreserved nuclear genome information. Complex statistical analysis of previously developed procedures resulted in information-rich data regarding factorial interactions helpful for developing protocols in genome-restoration programs.
