Abstract
Successful artificial breeding underpins rapid genetic and production gains in animal agriculture. In sheep, artificial insemination with frozen semen is performed via intrauterine laparoscopy as frozen-thawed spermatozoa do not traverse the cervix in sufficient numbers for high fertility and transcervical insemination is anatomically impossible in most ewes. Historically, laparoscopic artificial insemination has always been considered reasonably successful, but recent anecdotal reports of poor fertility place it at risk of warning adoption. Understanding the male, female and environmental factors that influence the fertility of sheep is warranted if the success of artificial insemination is to be improved and genetic progress maximised for the sheep industry. This review details the current practice of laparoscopic AI in sheep. It explores the effects of semen quantity and quality, the ewe, her preparation, and environmental conditions, on the fertility obtained following laparoscopic artificial insemination.

Abstract
Male fertility is affected by multiple endogenous stressors, including reactive oxygen species (ROS), which greatly deteriorate the fertility. However, physiological levels of ROS are required by sperm for the proper accomplishment of different cellular functions including proliferation, maturation, capacitation, acrosomal reaction, and fertilization. Excessive ROS production creates an imbalance between ROS production and neutralization resulting in oxidative stress (OS). OS causes male infertility by impairing sperm functions including reduced motility, deoxyribonucleic acid damage, morphological defects, and enhanced apoptosis. Several in-vivo and in-vitro studies have reported improvement in quality-related parameters of sperm following the use of different natural and synthetic antioxidants. In this review, we focus on the causes of OS, ROS production sources, mechanisms responsible for sperm damage, and the role of antioxidants in preserving sperm fertility.

Divar MR, Mogheiseh A, Mohammadi F, Mavalizadeh L. Effects of extender filtration and egg yolk concentration on canine semen cryopreservation. Reprod Domest Anim 2023; 58:272-287. [PMID: 36264284 DOI: 10.1111/rda.14284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 10/16/2022] [Accepted: 10/17/2022] [Indexed: 11/29/2022]
Abstract
The semen cooling and freezing extenders commonly contain the chicken egg yolk (EY) as the main sperm cryoprotectant. Besides its advantages, the EY has large lipoprotein granules that cause several physical and biological interferences. The previous studies have proposed several methods to resolve the problems with the EY-based semen extenders, including mechanical agitation, EY fractionation, replacing the EY with purified EY LDL, and ultrasonication. In the current research, we aimed to evaluate the syringe filtration (220 nm) of an EY-based canine semen freezing extender as a simple and cheap method to remove the EY granules. We also studied the possibility of re-aggregation of EY granules after cooling, freeze/thawing, and lyophilization/rehydration of the filtered extenders. Additionally, we compared the effects of the filtration on lipid profile, turbidity, EY particle size distribution, and osmolality of the EY-based extenders. Next, we examined the effects of filtered extenders containing different levels of EY (5%, 10%, 15%, 20%, and 25%) versus the control extender (20% EY, unfiltered) on post-thaw sperm quality traits. We collected the semen samples from seven clinically healthy mixed-breed adult dogs and pooled them for sperm freezing procedures. Samplings were repeated at least five times, independently. Our results indicated that the syringe filtration could remove the large EY particles and reduce the extender turbidity without affecting the lipid profile of the whole extender solution. The filtered extender supplemented with 25% (v/v) EY led to the best post-thaw canine spermatozoa quality markers. The frozen-thawed spermatozoa evaluations included motility parameters (computer-assisted semen analysis system), membrane and acrosome integrity (hypo-osmotic swelling test, chlortetracycline binding assay), DNA fragmentation (sperm chromatin dispersion assay), membrane lipid peroxidation (MDA levels), apoptosis (Annexin V/propidium iodide assay), and fertility-associated sperm mRNA transcript abundance (protamine 2 and 3). In conclusion, the syringe filtration of the EY-based semen extenders was a simple and cheap method that could effectively remove large EY lipoprotein granules and possibly prevent EY-origin bacterial contamination of the final extender solution. The EY at 25% (v/v) concentration in the filtered extenders resulted in the highest canine spermatozoa cryo-tolerance.

Abstract
The current study was designed to investigate the in ovo injection of formic acid (FA) on hatchability rate (HR; Experiment 1) and the potential ameliorative role of kinetin concurrent with FA on biochemical parameters of hatched broilers (Experiment 2). In Experiment 1, live embryonated eggs (n = 280; Day 4 of incubation) were in ovo injected with 0.03, 0.06, 0.125, 0.25, 0.50, 1, 2, 4, 8, 16 and 32 m m FA. In Experiment 2, intra-yolk-sac administration of toxic doses of FA (2 m m) concurrent with kinetin at 50, 100 or 200 µ m were evaluated on hatched embryos. The amount of malondialdehyde (MDA), total antioxidant capacity (TAC), total nitrate-nitrite (TNN), total lipid hydroperoxide (TLHP) and superoxide dismutase (SOD) activity was measured in serum, liver, heart and brain tissues. The results revealed that injection of 2 mM FA significantly increased mortality compared to the control group (p < 0.05). Concurrent administration of 50 or 100 µ m kinetin + 2 m m FA increased HR to 10% and 20% compared to the FA-alone-treated group, respectively. Intra-yolk-sac-received FA group showed greater amounts of MDA, TLHP and TNN and lesser amounts of TAC and SOD activity in serum and tissue samples of liver, heart and brain compared to control groups (p < 0.001). In comparison to the FA-alone-treated group, all doses of kinetin were able to increase the TAC levels in serum and tissue samples when administered concurrently with FA. The doses of 50 and 100 µ m kinetin were efficacious to ameliorate the toxic role of FA injection on SOD activities (p < 0.001). Co-injection of 100 µ m kinetin plus FA significantly reduced the amounts of MDA, TNN and TLHP in measured samples compared to the FA-alone-injected group (p < 0.001). Our results indicated that kinetin (especially at 100 µ m doses) would ameliorate the toxic effects of FA on developing live chicken embryos.

Abstract
Infertility is one of the disorders that worries many couples around the world, although novel and molecular methods can be used to cure this disease in different stages. One of the factors that causes infertility in men and women is the increased oxidative stress within the cells, which can lead to damage in zygote formation. ROMO1 is one of the most important proteins in the production of reactive oxygen species. This protein can enhance oxidative stress in the cells and body through cellular pathways, such as TNF-α and NF-κB routes, which will eventually lead to many diseases, especially infertility. We engage several international databases by using keywords; ROMO1, Infertility, and Reactive Oxygen Species, and gained a great quantity of information about ROMO1, Infertility, and Oxidative Stress. Although not proven, it is hypothesized that ROMO1 might elevate oxidative stress by activating NF-κB pathway in the cells, furthermore, TNF-α can arouse ROMO1 that can end up with apoptosis and cell death, which consequently can have a lot of disturbing effects on the body, especially the reproductive system. To sum up, revealing the exact cellular and molecular mechanisms of ROMO1-dependent TNF-α and NF-κB pathways in the pathogenesis of infertility might find interesting therapeutic and management strategies for this disorder.

Abstract
Cisplatin is a commonly used chemotherapeutic agent; however, its potential side effects, including gonadotoxicity and infertility, are a critical problem. Oxidative stress has been implicated in the pathogenesis of cisplatin-induced testicular dysfunction. We investigated whether kinetin use at different concentrations could alleviate gonadal injury associated with cisplatin treatment, with an exploration of the involvement of its antioxidant capacity. Kinetin was administered in different doses of 0.25, 0.5, and 1 mg/kg, alone or along with cisplatin for 10 days. Cisplatin toxicity was induced via a single IP dose of 7 mg/kg on day four. In a dose-dependent manner, concomitant administration of kinetin with cisplatin significantly restored testicular oxidative stress parameters, corrected the distorted sperm quality parameters and histopathological changes, enhanced levels of serum testosterone and testicular StAR protein expression, as well as reduced the up-regulation of testicular TNF-α, IL-1β, Il-6, and caspase-3, caused by cisplatin. It is worth noting that the testicular protective effect of the highest kinetin dose was comparable/more potent and significantly higher than the effects of vitamin C and the lowest kinetin dose, respectively. Overall, these data indicate that kinetin may offer a promising approach for alleviating cisplatin-induced reproductive toxicity and organ damage, via ameliorating oxidative stress and reducing inflammation and apoptosis.

Abstract
Nature is a rich source of biologically active novel compounds. Sixty years ago, the plant hormones cytokinins were first discovered. These play a major role in cell division and cell differentiation. They affect organogenesis in plant tissue cultures and contribute to many other physiological and developmental processes in plants. Consequently, the effect of cytokinins on mammalian cells has caught the attention of researchers. Many reports on the contribution and potential of cytokinins in the therapy of different human diseases and pathophysiological conditions have been published and are reviewed here. We compare cytokinin effects and pathways in plants and mammalian systems and highlight the most important biological activities. We present the strong profile of the biological actions of cytokinins and their possible therapeutic applications.

Abstract
Freeze storage of ejaculated sperms is a crucial technique for the semen preservation of valuable pet animals such as dogs. The current study was conducted to investigate if quercetin (QRN) may ameliorate apoptosis and oxidative stress in post-thaw dog sperm. Herein, we evaluated the post-thaw apoptosis and oxidative stress after treatment with QRN (control, 25, 50, and 100 μM) in the freezing of dog semen. Reactive oxygen species levels were significantly affected (p < 0.05) between the various concentrations of QRN and the control (17.56 ± 1.02, 7.54 ± 0.48, 5.66 ± 0.80, and 10.41 ± 0.69), respectively. The apoptosis index was 9.1 ± 1.34, 6.66 ± 0.58, 6.77 ± 0.66, and 5.38 ± 0.86 in the control, and 25, 50, and 100 μM QRN treatment groups, respectively (p < 0.05). The effects of ameliorated cryo-induced damage by QRN on post-thaw sperm quality were also observed through improved structural and functional tests. Sperm treated with 50 μM QRN showed significantly higher motility (51.8 ± 2.1% vs. 43.1 ± 1.4%, P < 0.05), survival rates (46.9 ± 0.7% vs. 43.9 ± 0.4%, P < 0.05), and mucus penetration than control group, respectively. Results also indicated that higher concentrations of QRN (100 μM) were not effective on sperm quality and parameters when compared with the medium levels (50 μM). In conclusion, supplementation of freezing buffer with 50 μM QRN reduced oxidative damage and improved the quality of post-thaw dog sperm.

Abstract
Assisted reproductive techniques (ARTs), such as artificial insemination, in vitro fertilization, and cryopreservation of gametes/zygotes, have been developed to improve breeding and reproduction of livestock and for the treatment of human infertility. Their widespread use has contributed to improvements in human health and welfare. However, in dogs, only artificial insemination using frozen semen is readily available as an ART to improve breeding and control genetic diversity. A recent priority in sperm cryopreservation is the development of alternatives to egg yolk, which is widely used as a component of the sperm extender. Egg yolk can vary in composition among batches and is prone to contamination by animal pathogens. The latter can be a problem for international exchange of cryopreserved semen. Low-density lipoprotein and skim milk are promising candidates for use as extenders, to ensure fertility after artificial insemination. Although not tested for its effects on fertility following artificial insemination, polyvinyl alcohol may also be a useful alternative to egg yolk as an extender. The development of cryopreservation techniques for canine embryos lags behind that for other mammals, including humans. However, given the success of non-surgical embryo transfer in 2011, studies have sought to refine this approach for practical use. Research on sperm cryopreservation has yielded satisfactory results. However, investigation of other approaches, such as cryopreservation of oocytes and gonadal tissues, remains insufficient. Techniques for the efficient induction of estrus may aid in the development of successful canine ARTs.

Cryoprotective Effects of Ergothioneine and Isoespintanol on Canine Semen. Animals (Basel) 2021; 11:ani11102757.

Abstract
Simple Summary Cryopreserving dog semen allows the long-term availability of male gametes for future artificial insemination and other assisted reproductive techniques. However, freezing causes irreversible damage to sperm that can affect its ability to fertilize and generate a viable pregnancy. Sperm alterations are partly attributed to oxidation produced by reactive oxygen species (ROS); therefore, antioxidants have been included as extenders for seminal cryopreservation. The unconventional natural antioxidants might reduce deleterious changes in cryopreserved dog sperm; therefore, we evaluated the effects of cryopreservation with the antioxidants ergothioneine and isoespintanol on thawed canine sperm. Various concentrations of both antioxidants improved the movement capacity and structure of thawed spermatozoa, possibly by reducing ROS production. The unconventional antioxidants isoespintanol and ergothioneine improved the quality of cryopreserved canine semen and hence improved assisted canine reproduction. Abstract Sperm undergo oxidative stress due to excessive production of reactive oxygen species (ROS) during cryopreservation. Some unconventional natural antioxidants can reduce ROS-induced changes in cryopreserved canine sperm. This study aimed to identify the cryoprotective effects of ergothioneine and isoespintanol on the quality of thawed canine semen. Twelve ejaculates from six dogs were cryopreserved in a tris-yolk extender without (control) or with 50 (E50), 100 (E100), or 150 (E150) µM ergothioneine or 20 (I20), 40 (I40), or 60 (I60) µM isoespintanol. We evaluated the motility and kinetics of thawed sperm using computerized analysis; determined morphology by eosin-nigrosin staining; functional membrane integrity using hypoosmotic tests, and structural membrane and acrosome integrity; mitochondrial membrane potential by fluorescence microscopy; and ROS production by spectrophotometry. Data were statistically analyzed using mixed models and Tukey tests. E100 increased total (60.6% vs. 49.6%) and progressive (26.4% vs. 20.1%) motility, straight line velocity (41.3 vs. 35.9 µm/s), and rapid sperm (17.6% vs. 12.3%) compared with controls. However, E150 reduced the numbers of hyperactive sperm. E100, I40, and I60 reduced the abnormal morphology and ROS production, and all concentrations of both antioxidants increased acrosomal integrity. We concluded that ergothioneine and isoespintanol reduce deleterious sperm alterations and oxidative stress in thawed canine semen.

Abstract
Sperm cryopreservation is a widely used assisted reproductive technology for canine species. The long-term storage of dog sperm is effective for the breeding of dogs living far apart, scheduling the time of artificial insemination that suits the female, and preventing diseases of the reproductive tract. However, spermatozoa functions are impaired during the freeze-thaw processes, which may decrease reproductive performance. Numerous attempts have been made to restore such impairments, including the use of cryoprotectants to prevent the damage caused by ice crystal formation, and supplementation of antioxidants to reduce reactive oxygen species generation due to osmotic stress during the procedure. Egg yolk derivatives, antioxidants, and, more recently, mesenchymal stem cells (MSCs) and their derivatives have been proposed in this research field. This review article will summarize the current literature available on the topic.

Abstract
Antioxidants have multiple protective roles in a variety of cells and thus can be used to
protect sperm against cryo-damage during freezing, which affects fertility. The
antioxidant resveratrol (3,5,4-trihydroxytrans-stilbene; RSV) has been reported to protect
the animal sperm during cryopreservation, including human sperm. In this study, we
assessed the protective effects of RSV supplementation on dog sperm cryopreservation.
Semen was collected from four dogs and the effect of different concentrations of RSV (0,
100, 200, and 400 µM) on post-thaw sperm quality was examined. After thawing, sperm
motility was assessed using computer-aided sperm analysis, and the structural integrity of
the plasma membrane, acrosome, and chromatin was examined. In addition, their
mitochondrial activity and gene expression were also assessed. Dog sperm cryopreserved
with 200 µM RSV showed significant improvement in post-thaw sperm motility and viability
compared with that of the control group (P<0.05). Moreover,
RSV-supplemented samples showed significantly higher numbers of sperm with an intact
plasma membrane, active mitochondria, and structural integrity of acrosomes and chromatin
than that of control samples (P<0.05). Furthermore, gene expression
showed that RSV supplemented samples showed lower expression of pro-apoptotic
(BAX), reactive oxygen species (ROS) modulator oxidative stress-related
(ROMO1) and 8-oxoguanine DNA glycosylase 1 (OGG1)
whereas higher expression levels of anti‐apoptotic (BCL2), protamine-2
(PRM2), protamine-3 (PRM3) and sperm
acrosome‐associated 3 (SPACA3) genes than control. Our results suggest
that RSV, at its optimum concentration, can be efficiently used as an antioxidant in the
cryopreservation of dog sperm.

Abstract
Assessment of male fertility is based on the evaluation of sperm. Semen evaluation measures various sperm quality parameters as fertility indicators. However, semen evaluation has limitations, and it requires the advancement and application of strict quality control methods to interpret the results. This article reviews the recent advances in evaluating various sperm-specific quality characteristics and methodologies, with the help of different assays to assess sperm-fertility status. Sperm evaluation methods that include conventional microscopic methods, computer-assisted sperm analyzers (CASA), and flow cytometric analysis, provide precise information related to sperm morphology and function. Moreover, profiling fertility-related biomarkers in sperm or seminal plasma can be helpful in predicting fertility. Identification of different sperm proteins and diagnosis of DNA damage has positively contributed to the existing pool of knowledge about sperm physiology and molecular anomalies associated with different infertility issues in males. Advances in methods and sperm-specific evaluation has subsequently resulted in a better understanding of sperm biology that has improved the diagnosis and clinical management of male factor infertility. Accurate sperm evaluation is of paramount importance in the application of artificial insemination and assisted reproductive technology. However, no single test can precisely determine fertility; the selection of an appropriate test or a set of tests and parameters is required to accurately determine the fertility of specific animal species. Therefore, a need to further calibrate the CASA and advance the gene expression tests is recommended for faster and field-level applications.

[PMID: 32858005 DOI: 10.1016/j.cryobiol.2020.08.007] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 08/14/2020] [Accepted: 08/21/2020] [Indexed: 10/23/2022]
Abstract
This present study investigated the effect of bioactive peptide (BAPT) (BAPT) on the quality of ram semen during cryopreservation. Ram ejaculates were extended with Tris buffer supplemented with no antioxidants (as control group), 20 μg/mL BAPT (as BAPT20 group), 40 μg/mL BAPT (as BAPT40 group) and 60 μg/mL BAPT (as BAPT60 group). After cryopreservation, sperm quality including motility, vitality, the percentage of hypoosmotic swelling test (HOST)-positive spermatozoa and the percentage of intact acrosomes was assessed. Furthermore, the malondialdehyde (MDA) in seminal plasma and spermatozoa were analyzed, followed by the measurement of superoxide dismutase (SOD), catalase (CAT) and glutathione-peroxidase (GSH-Px) levels in seminal plasma. After in vitro fertilization, the embryonic cleavage rates and development rates of different groups were analyzed to compare the developmental abilities of spermatozoa. The results showed that the post-thaw sperm motility was significantly higher in the BAPT60 group compared to those in the BAPT20, BAPT40 and control groups (P < 0.05). The percentage of live sperms significantly increased from 48.12 ± 2.35% for the BAPT20 group, 55.43 ± 2.16% for the BAPT40 group to 57.53 ± 3.15% for the BAPT60 group. The percentage of HOST-positive spermatozoa was significantly higher in the BAPT60 group than those in BAPT20, BAPT40 and control groups (P < 0.05). The MDA levels in seminal plasma and spermatozoa were significantly reduced with BAPT supplement (P < 0.05). Additionally, the SOD, CAT and GSH-Px levels in the BAPT experimental groups were significantly higher than those of the control group, which further indicated that BAPT significantly inhibit the reactive oxygen species (ROS) production during the cryopreservation of ram semen. Furthermore, the embryonic cleavage rates and development rates of the BAPT40 and BAPT60 groups were significantly increased in comparison with the BAPT20 and control groups (P < 0.05). In conclusion, BAPT improved the ram sperm quality via inhibiting the ROS production during cryopreservation, and could be applied as a promising supplement for ram semen cryopreservation.
