Hungerford AJ, Bakos HW, Aitken RJ. Addition of Vitamin C Mitigates the Loss of Antioxidant Capacity, Vitality and DNA Integrity in Cryopreserved Human Semen Samples. Antioxidants (Basel) 2024; 13:247. [PMID: 38397845 PMCID: PMC10885938 DOI: 10.3390/antiox13020247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 02/14/2024] [Accepted: 02/17/2024] [Indexed: 02/25/2024] Open
Abstract
Cryopreservation of human spermatozoa is a necessity for males suffering from infertility who cannot produce fresh semen for insemination. However, current ART cryopreservation protocols are associated with losses of sperm motility, vitality and DNA integrity, which are thought to be linked to the induction of oxidative damage and the toxic properties of commercial cryoprotectants (CPAs). Preventing or mitigating these losses would be hugely beneficial to sperm survival during ART. Therefore, in this in vitro investigation, lipid peroxidation, production of reactive oxygen species, movement characteristics, antioxidant capacity, vitality, and DNA integrity were examined in semen samples both pre- and post-cryopreservation with CPA supplementation. The findings revealed a 50% reduction in antioxidant capacity with CPA addition, which was accompanied by significant increases in generation of reactive oxygen species and formation of lipid aldehydes. These changes were, in turn, correlated with reductions in sperm viability, motility and DNA integrity. Antioxidant supplementation generated bell-shaped dose-response curves with both resveratrol and vitamin C, emphasising the vulnerability of these cells to both oxidative and reductive stress. At the optimal dose, vitamin C was able to significantly enhance vitality and reduce DNA damage recorded in cryopreserved human spermatozoa. An improvement in sperm motility did not reach statistical significance, possibly because additional pathophysiological mechanisms limit the potential effectiveness of antioxidants in rescuing this aspect of sperm function. The vulnerability of human spermatozoa to reductive stress and the complex nature of sperm cryoinjury will present major challenges in creating the next generation of cryoprotective media.

Abstract
Significance: Currently 10%-15% of couples in reproductive age face infertility issues. More importantly, male factor contributes to 50% of these cases (either alone or in combination with female causes). Among various reasons, impaired sperm function is the main cause for male infertility. Furthermore, mitochondrial dysfunction and oxidative stress due to increased reactive oxygen species (ROS) production, particularly of mitochondrial origin, are believed to be the main contributors. Recent Advances: Mitochondrial dysfunction, particularly due to increased ROS production, has often been linked to impaired sperm function/quality. For decades, different methods and approaches have been developed to assess mitochondrial features that might correlate with sperm functionality. This connection is now completely accepted, with mitochondrial functionality assessment used more commonly as a readout of sperm functionality. More recently, mitochondria-targeted compounds are on the frontline for both assessment and therapeutic approaches. Critical Issues: In this review, we summarize the current methods for assessing key mitochondrial parameters known to reflect sperm quality as well as therapeutic strategies using mitochondria-targeted antioxidants aiming to improve sperm function in various situations, particularly after sperm cryopreservation. Future Directions: Although more systematic research is needed, mitochondria-targeted compounds definitely represent a promising tool to assess as well as to protect and improve sperm function.

Abstract
The aim of the present study was to investigate the effects of tempol and straw size on rooster sperm post-thaw quality and fertility. Rooster semen was cryopreserved in Lake extender containing 0 (control), 5, 10, 15 and 20 μM tempol (in two different straw size, 0.25 and 0.5). The percentage of total and progressive sperm motility, VAP and VSL increased in the 10 µM tempol group. Moreover, 10 µM tempol led to lower ROS compared to other groups. The lowest percentage of apoptotic-like changes was detected when the extender was treated with 10 µM of tempol. The minimum ROS was observed in the group treated with 0.5 straw size. Straw size did not have any significantly effect on GPx and SOD activities and TAC of frozen-thawed sperm. The highest significant percentage of fertility and hatching rate were observed in 10 µM of tempol. The results of the present study showed that supplementation of the Lake cryopreservation medium with 10 µM tempol improved cryo-survival. Also, the results of the present study suggested that Lake cryopreservation medium with 0.5-ml straw may perhaps be an appropriate method to improve the quality and fertility post-thawed rooster sperm.

Abstract
Cryopreservation is an effective method to spread qualified ram spermatozoa for reproductive goals in different farms, but cryopreservation's shocks reduce sperm quality. This study investigated the efficacy of the new mitochondria-targeted antioxidant Mito-TEMPO on post-thawed quality of spermatozoa in sheep. Collected samples were divided into five groups and after dilution, received different doses of Mito-TEMPO (0, 0.5, 5, 50 and 500 µM), and frozen. Thawed sperm motility parameters, malondialdehyde content, membrane functionality, abnormal morphology, mitochondria activity, acrosome integrity, DNA fragmentation, ROS concentration, viability and apoptotic-like changes, were evaluated. According to the results, Mito-TEMPO (5 and 50 μM) improved (p ≤ 0.05) motility parameters, average path velocity, membrane functionality, mitochondria activity and viability compared with the other groups. Moreover, apoptotic-like changes, lipid peroxidation and ROS concentration were lower (p ≤ 0.05) in groups received 5 and 50 μM Mito-TEMPO. Mito-TEMPO showed no effect (p > 0.05) on sperm acrosome integrity, morphology and DNA fragmentation. In conclusion, Mito-TEMPO as a targeted antioxidant could be an efficient cryo-additive to enhance quality parameters of post-thawed ram semen.

Abstract
Semen cryopreservation is an effective strategy for distributing spermatozoa for artificial insemination, but this process reduces the fertility potential of post-thawed spermatozoa. The current study was conducted to assess effects of the novel mitochondria-targeted antioxidant "Mito-TEMPO" on ram sperm quality and fertility potential during the freeze-thawing process in a plant-based extender. Semen samples were diluted in extenders supplemented with 0, 0.5, 5, 50 and 500 µM Mito-TEMPO and then frozen using a standard protocol. Motility, abnormal morphology, acrosome integrity, membrane integrity, mitochondria membrane potential, viability, apoptotic-like changes, lipid peroxidation, DNA fragmentation, H2O2 concentration and fertility potential were assessed after thawing. Results indicated that with the 5 and 50 μM Mito-TEMPO there was a greater (P ≤ 0.05) percentage of sperm total motility, progressive motility, acrosome integrity and viability as well as less (P ≤ 0.05) lipid peroxidation and late apoptotic-like changes. Membrane integrity and mitochondria membrane potential were greater (P ≤ 0.05) with the 50 μM Mito-TEMPO extender supplementation. Furthermore, with 0.5, 5 and 50 μM Mito-TEMPO supplementations there was a greater (P ≤ 0.05) average path velocity and lesser (P ≤ 0.05) percentages of spermatozoa with DNA fragmentation and relatively greater H2O2 concentration. Results from the fertility experiment indicated the 5 and 50 μM Mito-TEMPO treatments resulted in greater pregnancy, parturition and lambing rates. It, therefore, is concluded that Mito-TEMPO may enhance quality and fertility potential of post-thawed semen of rams.

Abstract
Cryoprotectant-free vitrification is a common method for spermatozoa cryopreservation by direct plunging into liquid nitrogen. However, the commercial liquid nitrogen could be potentially contaminated by microorganisms. Warming temperature plays an essential role for quality of human spermatozoa after vitrification. This study aimed to evaluate comparatively a quality spermatozoa after vitrification in liquid nitrogen and clean liquid air as well as with two warming rates: at 42 °C and 45 °C. After performing of routine swim-up of normozoospermia samples, spermatozoa from the same ejaculate were divided into two groups: vitrified in liquid nitrogen (LN) and sterile liquid air (LA). Spermatozoa of LN group were warmed at 42 °C, and spermatozoa of LA groups were divided and warmed at 42 °C (LA42) and 45 °C (LA45). Then spermatozoa motility, reactive oxygen species (ROS), mitochondrial membrane potential (MMP), reactive nitrogen species (RNS), and viability were assessed. It was no found significant differences in quality of spermatozoa from LN and LA groups in the motility, ROS, MMP, RNS rates after warming at 42 °C. A tendency to obtain better spermatozoa quality was found with using of warming by 42 °C in comparison with 45 °C. It was concluded that cryoprotectant-free vitrification by direct dropping of human spermatozoa into clean liquid air can be used as an alternative to cooling in liquid nitrogen. Warming of spermatozoa at 42 °C allows to preserve the spermatozoa physiological parameters.

Abstract
The protocol of aseptic cryoprotectant-free vitrification on human spermatozoa is well documented. However, data about the effect of permeable cryoprotectants at this procedure is limited. Presented study aimed to test the aseptic capillary vitrification technologies using permeable cryoprotectant-included or cryoprotectant-free media. Thirty-two normal samples were included and analyzed after vitrification in three different media and thawing. Three treatment groups were formed: Group 1, basic medium; Group 2, basic medium with 0.25 M sucrose; Group 3, basic medium with glycerol. Before plunging into liquid nitrogen, capillaries were filled by 10 μl of spermatozoa suspension and isolated from liquid nitrogen by location in hermetically closed 0.25 ml straws. Progressive motility, plasma membrane integrity, total motility/viability after 24, 48 and 72 h in vitro culture, apoptosis and mitochondrial membrane potential (ΔΨm) were determined after thawing at 42 °C. Progressive motility of spermatozoa in groups 1, 2, 3 was 24.9 ± 1.7%, 34.5 ± 2.8% and 34.0 ± 1.4%, respectively (P1-2,3<0.05). The plasma membrane integrity of spermatozoa in groups 2 and 3 (48.4 ± 2.9% and 45.5 ± 3.9%, respectively) was higher than in Group 1 (33.3 ± 2.1%, P < 0.05). After 24 h, 48 h and 72 h in vitro culture, the total motility and viability of spermatozoa in Group 1 was significantly lower than Group 2 and Group 3. The apoptosis rate in Group 3 (44.5 ± 3.0%) and Group 2 (47.7 ± 4.1%) were lower than in Group 1 (52.5 ± 4.4%; P < 0.05). ΔΨm rates in Group 3 and Group 2 were higher than in Group 1 (P < 0.05) with no statistical differences between this parameter in Group 2 and Group 3 (P > 0.1). In conclusion, supplementation of medium for aseptic capillary technology for cryoprotectant-free vitrification of human spermatozoa by permeable cryoprotectant does not improve the quality of spermatozoa after warming.

Abstract
Rooster semen cryopreservation is a useful method to utilize semen samples for artificial insemination in commercial flocks, but with use of the freezing-thawing process there is a reduction in the quality and fertilization capacity of rooster spermatozoa post-thawing. The aim of the current study was to investigate the efficacy of the mitochondria-targeted antioxidant Mito-TEMPO on rooster sperm quality and fertilization capacity after conducting the freezing-thawing processes. Semen samples were diluted and there were five equal aliquots supplemented with 0, 0.5, 5, 50 and 500 μM Mito-TEMPO. Semen samples were subsequently cryopreserved in liquid nitrogen. After thawing, sperm motility, lipid peroxidation, membrane functionality, normal morphology, mitochondria active potential, acrosome integrity, viability, apoptotic-like changes, DNA fragmentation, hydrogen peroxide concentration and fertilizing capacity were evaluated. Supplementation of Lake medium with 5 and 50 μM Mito-TEMPO resulted in greater (P ≤ 0.05) total sperm motility, progressive motility, average path velocity, membrane functionality, mitochondria active potential, acrosome integrity and viability compared with semen of the other groups. Lipid peroxidation, late apoptotic-like changes, DNA fragmentation and hydrogen peroxide content, however, were less (P ≤0.05) in semen samples supplemented with 5 and 50 μM Mito-TEMPO compared to other groups. Furthermore, fertility percentages were greater when there was supplementation with 5 and 50 μM Mito-TEMPO compared to the control group. Mitochondria-targeted antioxidant Mito-TEMPO could be included in semen extender before cryopreservation to improve quality and fertilization capacity of rooster semen after thawing of cryopreserved samples.

Abstract
The addition of an antioxidant to cryopreservation solutions for preventing oxidative stress to sperm from several species, including that from humans, has been studied previously. Quercetin is a flavonoid contained in subarctic trees with freeze resistance and is known to be a strong antioxidant. Therefore, the effect of quercetin on the cryopreservation of dog spermatozoa was examined in this study. The proportions of total motile spermatozoa were significantly higher at 30, 60, 90, 120, and 150 min and at 60, 120, and 150 min after thawing in groups treated with 5 μg/ml and 10 μg/ml of quercetin dissolved in 0.1% DMSO added to the second extender based on skim milk compared to that in the control group, respectively. There were no differences between the experimental groups in the proportion of total motile spermatozoa during the observation periods. The proportion of total motile spermatozoa among those treated with 5 μg/ml of quercetin in 0.1% DMSO was improved by approximately 10-20% at 30-180 min after thawing compared to that in the control group. To evaluate the fertility of cryopreserved spermatozoa treated with quercetin, 2 × 108 spermatozoa were transcervically inseminated into bitches, and a total of 18 puppies were delivered in three bitches. These results indicated that supplementation of quercetin as a cryoprotectant to the skim milk-based extender improved the motility of cryopreserved spermatozoa from dogs compared to those of the control group. And fertility of cryopreserved spermatozoa with quercetin supplementation was proven with higher efficiency.

Abstract
The PUFAs content of rooster sperm cells makes them vulnerable to the thermal shocks during chilling storage, which reduces the fertility performance of cooled sperm. Extender supplementation with antioxidants is a reasonable method to conserve sperm fertility potential during cooling storage process. The aim of this study was to determine the effect of Mito-TEMPO addition to the Lake medium on rooster sperm quality and fertility potential during cooling process. Semen samples were diluted in the Lake medium and assigned into five equal aliquots and supplemented with 0, 0.5, 5, 50 and 500 μM Mito-TEMPO. Then, the samples were cooled at 5 °C and conserved up to 50 h. Total motility, progressive motility, morphology, viability, membrane integrity, lipid peroxidation and mitochondrial activity of samples were analyzed during 0, 25 and 50 h of cooling period. Artificial insemination was also conducted using 25 h-cooled semen. No significant difference was observed among different treatments during quality evaluations at 0 h storage. Extender supplementation with 5 and 50 μM Mito-TEMPO presented greater (P ≤ 0.05) total motility, progressive motility, viability, membrane integrity and lower lipid peroxidation compared to other groups during 25 and 50 h cooling storage. Mitochondrial activity was higher (P ≤ 0.05) in groups received 5, 50 and 500 μM Mito-TEMPO than others. Fertility rate of 25 h-cooled-stored samples was higher (P ≤ 0.05) in groups containing 5 and 50 μM Mito-TEMPO compared to control group. In conclusion, addition of 5 and 50 μM Mito-TEMPO as a mitochondria-targeted antioxidant to the storage medium could be a suitable method to conserve rooster semen quality against stressful conditions of cooling storage process.

Supplementation of freezing media with alpha lipoic acid preserves the structural and functional characteristics of sperm against cryodamage in infertile men with asthenoteratozoospermia. Cryobiology 2020; 96:166-174. [PMID: 32652098 DOI: 10.1016/j.cryobiol.2020.07.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 06/26/2020] [Accepted: 07/04/2020] [Indexed: 10/23/2022]
Abstract
The aim of this study was to examine the effects of alpha lipoic acid (ALA) supplementation during semen cryopreservation on the sperm quality, chromatin integrity, oxidative stress, and expression level of BAX, BCL2, HSP70 and iNOS genes in semen samples obtained from infertile men with asthenoteratozoospermia. METHODS Twenty freshly ejaculated semen samples were cryopreserved with sperm freezing medium supplemented with 0.00, 0.02, 0.05, 0.1, 0.5, and 1 mmol/mL of ALA. The samples were analyzed according to the WHO guidelines before and after freezing. Sperm ROS production level, DNA fragmentation and cryo-capacitation were assessed using flow cytometry, TUNEL assay and chlortetracycline (CTC) test, respectively. Expression level of stress protein (HSP70), pro-apoptotic Bax, anti-apoptotic Bcl-2, and iNOS genes was assessed by real-time PCR assay. RESULTS The effective concentrations of ALA (0.02 and 0.5 mM) significantly improved the motility, viability and morphology of the frozen-thawed sperms compared to the control group treated with 0.00 mM of ALA. During cryopreservation, treatment of semen with 0.02 mM of ALA, as the optimal concentration, significantly decreased DNA fragmentation and oxidative stress level (P < 0.05), protected the acrosome integrity, and led to insignificant reduction in BAX gene expression level and significant increase in expression level of BCL2, HSP70, and iNOS genes compared with control group. CONCLUSION Our findings revealed that the adding ALA to semen samples obtained from infertile men with asthenoteratozoospermia plays a significant protective role against cryodamage by preserving the sperm functional parameters.

The efficacy of antioxidants in sperm parameters and production of reactive oxygen species levels during the freeze-thaw process: A systematic review and meta-analysis. Andrologia 2020; 52:e13514. [PMID: 31967363 DOI: 10.1111/and.13514] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 11/27/2019] [Accepted: 12/13/2019] [Indexed: 11/30/2022] Open
Abstract
To investigate the impact of antioxidants in sperm parameters and reduction in reactive oxygen species production during the freeze-thaw process. PubMed, Scopus, Web of Science, Embase and Cochrane central library were systematically searched. Of the 1583 articles, 23 studies were selected for data extraction. Our results show that antioxidants improved sperm progressive motility (standardised mean difference (SMD) = 1; 95% CI: 0.62, 1.38; p < .001) and viability (SMD = 1.20; 95% CI: 0.50, 1.91; p = .001) and reduced sperm DNA fragmentation (SDF) and hydrogen peroxide (H2 O2 ) production, but there was no significant improvement in total sperm motility after thawing. Acetyl-l-carnitine/l-carnitine, melatonin and catalase had a significant positive impact on progressive motility. The role of tempol and melatonin in improving viability was significant compared to other antioxidants. Moreover, a significant reduction in SDF was observed after addition of butylated hydroxytoluene, tempol and vitamin E. However, the prevention of H2 O2 production was significant only after the addition of tempol. Our overall results displayed the positive impact of antioxidants on progressive sperm motility, viability and reduction in SDF and H2 O2 production, but no significant impact of antioxidants on total sperm motility was seen during the freeze-thaw process.

Abstract
The cryopreservation of spermatozoa was introduced in the 1960s as a route to fertility preservation. Despite the extensive progress that has been made in this field, the biological and biochemical mechanisms involved in cryopreservation have not been thoroughly elucidated to date. Various factors during the freezing process, including sudden temperature changes, ice formation and osmotic stress, have been proposed as reasons for poor sperm quality post-thaw. Little is known regarding the new aspects of sperm cryobiology, such as epigenetic and proteomic modulation of sperm and trans-generational effects of sperm freezing. This article reviews recent reports on molecular and cellular modifications of spermatozoa during cryopreservation in order to collate the existing understanding in this field. The aim is to discuss current freezing techniques and novel strategies that have been developed for sperm protection against cryo-damage, as well as evaluating the probable effects of sperm freezing on offspring health.

Abstract
Objective A recent innovative approach, based on induction of sublethal oxidative stress to enhance sperm cryosurvival, has been applied before sperm cryopreservation. The purpose of this study was to investigate the effects of different induction times of sublethal oxidative stress before cryopreservation on human post-thawed sperm quality. Materials and Methods In this experimental study, we selected semen samples (n=20) from normozoospermic men according to 2010 World Health Organization (WHO) guidelines. After processing the samples by the density gradient method, we divided each sample into 5 experimental groups: fresh, control freezing, and 3 groups exposed to 0.01 μM sodium nitroprusside (SNP) [nitric oxide (NO) donor] for 30 (T30), 60 (T60), or 90 minutes (T90) at 37˚C and 5% CO2 before cryopreservation. Motion characteristics [computer-assisted sperm analyser], viability, apoptosis [annexin V/propidium iodide (PI) assay], DNA fragmentation [sperm chromatin structure assay (SCSA)], and caspase 3 activity (FLICA Caspase Detection Kit) were assessed after thawing. The results were analysed by using one-way ANOVA and Tukey's test. The means were significantly different at P<0.05. Results Cryopreservation significantly decreased sperm viability and motility parameters, and increased the percentage of apoptosis, caspase 3 activity, and DNA fragmentation (P<0.01) compared to the fresh group. The T60 group had a higher significant percentage of total motility (TM) and progressive motility compared with other cryopreserved groups (P<0.05). We observed a significantly lower percentage of apoptotic rate and caspase 3 activity in the T60 group compared to the other cryopreserved groups (P<0.05). DNA integrity was not significantly affected by this time of sublethal stress induction (P>0.05). Conclusion Our results have demonstrated that the application of sublethal oxidative stress by using 0.01 μM NO for 60 minutes before the freezing process can be a beneficial approach to improve post-thawed human sperm quality.
