Network pharmacology and molecular docking reveal potential mechanisms of ginseng in the treatment of diabetes mellitus-induced erectile dysfunction and asthenospermia.

Diabetes mellitus (DM) is a chronic metabolic disease that predisposes to chronic damage and dysfunction of various organs, including leading to erectile dysfunction (ED) and asthenospermia. Literature suggests that ginseng plays an important role in the treatment and management of DM. Ginseng may have a therapeutic effect on the complications of DM-induced ED and asthenospermia. The study aimed to explore the mechanisms of ginseng in the treatment of DM-induced ED and asthenospermia following the Traditional Chinese Medicine (TCM) theory of "treating different diseases with the same treatment." This study used network pharmacology and molecular docking to examine the potential targets and pharmacological mechanism of Ginseng for the treatment of DM-induced ED and asthenospermia. The chemical ingredients and targets of ginseng were acquired using the Traditional Chinese Medicine Systems Pharmacology database and analysis platform. The targets of DM, ED, and asthenospermia were extracted with the GeneCards and Online Mendelian Inheritance in Man databases. A protein-protein interaction network analysis was constructed. The Metascape platform was applied for analyzing the gene ontology and Kyoto Encyclopedia of Genes and Genomes pathways. AutoDock Vina was used to perform molecular docking. Network pharmacology revealed that the main active components of the target of action were kaempferol, beta-sitosterol, ginsenoside rh2, stigmasterol, and fumarine. Core targets of the protein-protein interaction network included TNF, IL-1ß, AKT1, PTGS2, BCL2, and JUN. Kyoto Encyclopedia of Genes and Genomes enrichment analysis showed that they were mainly involved in AGE-RAGE signaling pathway in diabetic complications, TNF signaling pathway, Lipid and atherosclerosis. The interactions of core active components and targets were analyzed by molecular docking. Ginseng may play a comprehensive therapeutic role in the treatment of DM-induced ED and asthenospermia through "multicomponent, multi-target, and multi-pathway" biological mechanisms such as inflammation and oxidative stress.

[Omega-3 polyunsaturated fatty acids for the treatment of oligoasthenozoospermia: Progress in research].

Oligoasthenozoospermia (OAS) is one of the most common types of male infertility, which, however, still lacks effective treatment. An increasing number of studies have shown the potential therapeutic value of omega-3 polyunsaturated fatty acid (ω-3 PUFA) in the treatment of OAS. This article presents an overview of the studies on the effects of ω-3 PUFA on fatty acid composition and metabolism, inflammatory response, and oxidative stress in OAS, hoping to provide some new ideas for the treatment of the disease.

[Linggui Formula for asthenospermia with kidney deficiency and blood stasis: A randomized controlled trial].

OBJECTIVE: To observe the effect and safety of the traditional Chinese medicine (TCM) Linggui Formula (LGF) in the treatment of asthenospermia with kidney deficiency and blood stasis. METHODS: This randomized controlled trial included 90 cases of asthenospermia with kidney deficiency and blood stasis treated in our hospital from September 2022 to September 2023, 45 by oral medication with LGF (the trial group) and the other 45 with oral levocarnitine solution (the control group), all for 12 weeks. We followed up the patients for 12 weeks, recorded the semen parameters, TCM syndrome scores, sexual hormone levels, pregnancy rates, and DNA fragmentation index (DFI) of the patients, and compared them between the two groups before and after treatment. RESULTS: Totally, 82 of the patients completed the study, 42 in the trial and 40 in the control group. After treatment, the patients in the trial group showed significant increases in the percentage of progressively motile sperm (PMS) (from ï¼»19.25±3.08ï¼½% to ï¼»38.57±4.99ï¼½%, P< 0.05), total sperm motility (from ï¼»32.29±3.64ï¼½% to ï¼»46.50±4.77ï¼½%, P< 0.05) and sperm concentration (from ï¼»83.9±37.2ï¼½ to ï¼»95.1±34.9ï¼½× 106/ml ï¼½, P< 0.05), and so did the controls in PMS (from ï¼»19.75±4.28ï¼½% to ï¼»34.46±5.07ï¼½%, P< 0.05), total sperm motility (from ï¼»33.02±4.93ï¼½% to ï¼»43.11±4.72ï¼½%, P< 0.05) and sperm concentration (from ï¼»85.2±39.7ï¼½ to ï¼»88.1±35.2ï¼½ × 106/ml , P< 0.05), all even more significant in the trial than in the control group (P< 0.05). No statistically significant difference was observed in the semen volume either in the trial (from ï¼»3.38±0.38ï¼½ to ï¼»3.24±0.45ï¼½ ml, P> 0.05) or in the control group (from ï¼»3.46±0.52ï¼½ to ï¼»3.30±0.37ï¼½ ml, P> 0.05), or between the trial and control groups (P> 0.05), or in the sexual hormone levels, pregnancy rates, and sperm DFI between the two groups before and after treatment (P> 0.05). Both groups of patients had good safety profiles without serious adverse reactions. CONCLUSION: Linggui Formula can improve the percentage of PMS in asthenospermia patients with kidney deficiency and blood stasis, potentially enhancing pregnancy rates and with a good safety.

Scriptaid is a prospective agent for improving human asthenozoospermic sample quality and fertilization rate in vitro.

ABSTRACT: Male infertility is a global issue caused by poor sperm quality, particularly motility. Enhancement of the sperm quality may improve the fertilization rate in assisted reproductive technology (ART) treatment. Scriptaid, with a novel human sperm motility-stimulating activity, has been investigated as a prospective agent for improving sperm quality and fertilization rate in ART. We evaluated the effects of Scriptaid on asthenozoospermic (AZS) semen, including its impact on motility stimulation and protective effects on cryopreservation and duration of motility, by computer-aided sperm analysis (CASA). Sperm quality improvement by Scriptaid was characterized by increased hyaluronan-binding activity, tyrosine phosphorylation, adenosine triphosphate (ATP) concentration, mitochondrial membrane potential, and an ameliorated AZS fertilization rate in clinical intracytoplasmic sperm injection (ICSI) experiments. Furthermore, our identification of active Scriptaid analogs and different metabolites induced by Scriptaid in spermatozoa lays a solid foundation for the future biomechanical exploration of sperm function. In summary, Scriptaid is a potential candidate for the treatment of male infertility in vitro as it improves sperm quality, prolongs sperm viability, and increases the fertilization rate.

Determination of the signaling proteins responsible for the antioxidant potential of the Yishenhuoxue formula for treating asthenospermia in rats.

Asthenospermia is a predominant cause of male infertility, and antioxidant supplements can be effective in treating asthenospermia. We demonstrate the antioxidant potential of traditional Chinese medicine, the Yishenhuoxue (YSHX) formula, in treating polyglycosides of Tripterygium wilfordii (GTW)-induced asthenospermia in rats. Fifty male rats were randomly divided into the normal, model, and treatment groups. HE staining was used to evaluate the improvement of spermatogenic function of rats, and TBA reaction, qRT-PCR, Western Blot and other methods were used to determine the changes of oxidative stress indicators and to evaluate the improvement of antioxidant capacity of rats by YSHX. Comparison with the model group showed significant improvement in pathological damage caused by GTW to seminiferous tubules. MDA and NO content in rat testes decreased, especially in middle- and high-dosage groups. No significant changes were observed in SOD and CAT activity or mRNA expression. GSH-Px activity and GSH mRNA expression were significantly higher in the low-dosage group than in the model group. Compared to the model group, GR activity was significantly lower in the middle and high dosage groups, while the mRNA expression was higher. The PKC-beta level increased, while p-ERK1/2, NF-κB, and the ratio of p-ERK1/2*(ERK1/2)-1 decreased significantly in the treatment groups. Therefore, YSHX can alleviate GTW-induced testicular damage, enhance GSH-Px activity, regulate GSH redox cycling, and mitigate oxidative stress injury. Furthermore, YSHX can promote PKC-beta expression and inhibit the phosphorylation of ERK1/2 and NF-κB. Using YSHX may be an effective way to increase sperm motility via the PKC-ERK1/2-NF-ĸB axis.

The evaluation effect of nanoliposome-loaded Mito-Tempo on sperm parameters during human sperm cryopreservation.

AIM: The aim of this study is the evaluation effect of nanoliposome-loaded Mito-Tempo on sperm parameters during human sperm cryopreservation. METHODS: Semen samples of 50 Asthenoteratozoospermia men (random) were collected. Sperm parameters were analyzed based on World Health Organization (WHO, 2010) criteria (2021) and each sample was divided into 5 groups (E1-E5). E1 (control group): the sperm was cryopreserved without nanoliposome, and Mito-Tempo. E2: sperm cryopreservation with Mito-Tempo-loaded nanoliposome (Mito-Tempo 0.1 mM) + freezing medium. E3: sperm cryopreservation with Mito-Tempo-loaded nanoliposome (Mito-Tempo 0.2 mM) + freezing medium. E4: in this group, the cryopreservation sperm with Mito-Tempo 0.3 mM + freezing medium. E5: the cryopreservation sperm with Mito-Tempo 0.2 mM + freezing medium. RESULTS: The result of this study indicated that sperm parameters and total antioxidant capacity (TAC) significantly increase in E3 and E4 groups, compared to E1, E2, and E5 groups respectively (P < 0.05). The percentage of abnormal morphology, DNA fragmentation index (DFI), malondialdehyde (MDA), and the levels of ROS significantly decrease in E3 and E4 groups, compared to E1, E2, and E5 groups (P < 0.05). In addition, the sperm parameters and stress oxidative factors significantly improve in E3 group compared to other groups (P < 0.05). CONCLUSIONS: In conclusion, the combination of Mito-Tempo with nanoliposome due to its ability to cooperate with lipid layers may lead to significant performance in reducing oxidative stress damage and increasing the quality of sperm parameters.

Betaine alleviates spermatogenic cells apoptosis of oligoasthenozoospermia rat model by up-regulating methyltransferases and affecting DNA methylation.

BACKGROUND: Oligoasthenozoospermia is the most common type of semen abnormality in male infertile patients. Betaine (BET) has been proved to have pharmacological effects on improving semen quality. BET also belongs to endogenous physiological active substances in the testis. However, the physiological function of BET in rat testis and its pharmacological mechanism against oligoasthenozoospermia remain unclear. PURPOSE: This research aims to prove the therapeutic effect and potential mechanism of BET on oligoasthenozoospermia rat model induced by Tripterygium wilfordii glycosides (TWGs). METHODS: The oligoasthenozoospermia rat model was established by a continuous gavage of TWGs (60 mg/kg) for 28 days. Negative control group, oligoasthenozoospermia group, positive drug group (levocarnitine, 300 mg/kg), and 200 mg/kg, 400 mg/kg, and 800 mg/kg BET groups were created for exploring the therapeutic effect of BET on the oligoasthenozoospermia rat model. The therapeutic effect was evaluated by HE and TUNEL staining. Immunofluorescence assay of DNMT3A, PIWIL1, PRMT5, SETDB1, BHMT2, and METTL3, methylation capture sequencing, Pi-RNA sequencing, and molecular docking were used to elucidate potential pharmacological mechanisms. RESULTS: It is proved that BET can significantly restore testicular pathological damage induced by TWGs, which also can significantly reverse the apoptosis of spermatogenic cells. The spermatogenic cell protein expression levels of DNMT3A, PIWIL1, PRMT5, SETDB1, BHMT2, and METTL3 significantly decreased in oligoasthenozoospermia group. 400 mg/kg and 800 mg/kg BET groups can significantly increase expression level of the above-mentioned proteins. Methylation capture sequencing showed that BET can significantly increase the 5mC methylation level of Spata, Spag, and Specc spermatogenesis-related genes. Pi-RNA sequencing proved that the above-mentioned genes produce a large number of Pi-RNA under BET intervention. Pi-RNA can form complexes with PIWI proteins to participate in DNA methylation of target genes. Molecular docking indicated that BET may not directly act as substrate for methyltransferase and instead participates in DNA methylation by promoting the methionine cycle and increasing S-adenosylmethionine synthesis. CONCLUSION: BET has a significant therapeutic effect on oligoasthenozoospermia rat model induced by TWPs. The mechanism mainly involves that BET can increase the methylation level of Spata, Specc, and Spag target genes through the PIWI/Pi-RNA pathway and up-regulation of methyltransferases (including DNA methyltransferases and histone methyltransferases).

Association of Serum Vitamin D level with Asthenozoospermic Male.

Although vitamin D deficiency is one of the most common health problems throughout the world, conflicting information exists on the potential association between serum vitamin D levels and semen quality. Currently available data identifies that vitamin D has a vital role in reproductive process as it affects sperm motility. This study was done with the rationality to evaluate the association between serum vitamin D levels with asthenozoospermic males. This cross-sectional analytic study was conducted on 314 men who attended the Department of Reproductive Endocrinology and Infertility, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh July 2018 to June 2019. Considering the inclusion and exclusion criteria all participants were categorized into two groups; Group I included 157 asthenozoospermic male and Group II included 157 normozoospermic male according to World Health Organization 'strict' criteria 2010. Participants completed the questionnaires after they had agreed on a informed consent. Blood and semen samples were obtained for assessment and all data were adjusted for age, body mass index (BMI), total motility and progressive motility. Vitamin D levels were classified according to the Endocrine Society guideline. Statistical analyses were carried out by using the Statistical Package for Social Sciences version 22.0 for Windows (SPSS Inc., Chicago, Illinois, USA). The results showed that the mean vitamin D level was 16.63±5.54ng/ml in asthenozoospermic group and 19.83±5.33ng/ml in normozoospermic group. The mean vitamin D level was significantly (p<0.05) lower in asthenozoospermic group. It was noticed that 86.6% patients had vitamin D deficiency (≤20ng/ml) in asthenozoospermic group compared to 56.7% in the normozoospermic group. The study found that low vitamin D was associated with a fivefold increased risk of developing asthenozoospermia at 95% CI (2.74-8.99). Moreover, there was a positive significant correlation (r=0.285; p<0.001) between serum vitamin D level with total motility and progressive motility (r=0.232; p<0.001). Hence, the study suggests a significant association between asthenozoospermia and low vitamin D levels. However, clinical trials are warranted to further reinforce the findings.

Phoenix dactylifera L. pollen versus pentoxifylline on improvement of sperm parameters in idiopathic male infertility: A randomized clinical trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Phoenix dactylifera L. pollen is the male reproductive dust of palm flowers known as a natural product that is considered a strong stimulant of sexual potency and fertility in Iranian traditional medicine (ITM). In this regard, no evidence-based medications are empirically prescribed to treat IMI. However, applying traditional medicine for the treatment of male infertility has attracted more attention in recent years. AIM OF THE STUDY: Phoenix dactylifera L. pollen was compared with pentoxifylline (PTX) to evaluate its efficacy on sperm parameters. MATERIALS AND METHODS: During this parallel randomized controlled trial, 80 adult men with asthenozoospermia, oligozoospermia, or teratozoospermia (age 20-35 years) were enrolled. In two separate groups of participants with a 1:1 ratio, participants received either 6 g of Phoenix dactylifera L. pollen powder daily or 400 mg of PTX tablets daily for 90 days. We measured the sperm parameters as well as the serum sex hormones in the sample. ANCOVA and t-tests were used to compare groups. RESULTS: There was no significant difference between the study groups in terms of baseline characteristics or demographic characteristics. According to the results, participants who took Phoenix dactylifera L. pollen powder had significantly improved sperm concentration (p = 0.016), morphology (p = 0.029), sperm counts (p = 0.012), progressive motility (p = 0.016), total motility (p = 0.018), and reduced immotile sperms (p = 0.014) compared to those who took PTX. CONCLUSIONS: In light of these results, Phoenix dactylifera L. pollen is recommended as a treatment factor for ameliorating IMI by enhancing sperm functional capacity and semen parameters.

Antioxidant treatment for oligoasthenoteratozoospermia and varicocele: a DBPC trial to evaluate the impact of age and body mass index.

Oxidative stress is one of the main mechanisms responsible for male infertility. Various conditions such as varicocele, obesity, advanced age, and lifestyle can lead to an increase in reactive oxygen species, causing an oxidative imbalance in the reproductive environment. Spermatozoa are sensitive to reactive oxygen species and require energy to carry out their main function of fertilizing the egg. Excessive reactive oxygen species can affect sperm metabolism, leading to immobility, impaired acrosome reaction, and cell death, thereby impairing reproductive success. This double-blind randomized study evaluated the effect of supplementation with L-carnitine, acetyl-L-carnitine, vitamins, and other nutrients on semen quality in 104 infertile patients with or without varicocele, while also investigating the impact of factors such as obesity and advanced age on treatment. Sperm concentration significantly increased in the supplemented group compared to the placebo group ( P = 0.0186). Total sperm count also significantly increased in the supplemented group ( P = 0.0117), as did sperm motility ( P = 0.0120). The treatment had a positive effect on patients up to 35 years of age in terms of sperm concentration ( P = 0.0352), while a body mass index (BMI) above 25 kg m -2 had a negative effect on sperm concentration ( P = 0.0110). Results were not showing a net benefit in stratifying patients in accordance with their BMI since sperm quality increase was not affected by this parameter. In conclusion, antioxidant supplementation may be beneficial for infertile patients and has a more positive effect on younger patients with a normal weight.

Effect of antioxidants on semen parameters in men with oligo-astheno-teratozoospermia: a network meta-analysis.

BACKGROUND: Although antioxidants are largely used in subfertile men with oligo-astheno-teratozoospermia (OAT), the choice among different molecules is challenged by the lack of comparative head-to-head studies. The network meta-analysis (NMA) can overcome limitations of pairwise meta-analyses, since it incorporates direct and indirect evidence into a single model generating an effectiveness hierarchy. OBJECTIVE: To assess with a NMA the effects of antioxidants in improving seminal parameters in idiopathic OAT. MATERIALS AND METHODS: PubMed, Scopus, Cinahl, and Cochrane Library databases were searched for randomized controlled trials (RCTs) comparing any antioxidant treatment to each other or placebo in men with at least one idiopathic seminal abnormality. Data were included in a random-effects NMA, where efficacy of treatments was ranked by surface under the cumulative ranking curve (SUCRA). RESULTS: 29 RCTs provided information on 2045 men (mean age: 33.5 years) with idiopathic OAT and 19 antioxidant preparations. Compared to placebo, l-carnitine, especially in combination with l-acetyl-carnitine (LAC), had the highest SUCRA for sperm concentration, progressive motility, and morphology. Folate was the only other compound effective on sperm concentration. Vitamin E+selenium or zinc had the highest SUCRA for total motility. A contribution on progressive motility was revealed for pentoxifylline and vitamin E+CoQ10.

Chestnut polysaccharide rescues the damaged spermatogenesis process of asthenozoospermia-model mice by upregulating the level of palmitic acid.

Introduction: In recent years, the quality of male semen has been decreasing, and the number of male infertilities caused by asthenozoospermia is increasing year by year, and the diagnosis and treatment of patients with asthenozoospermia are gradually receiving the attention of the whole society. Due to the unknown etiology and complex pathogenesis, there is no specific treatment for asthenozoospermia. Our previous study found that the administration of chestnut polysaccharide could alter the intestinal microbiota and thus improve the testicular microenvironment, and rescue the impaired spermatogenesis process by enhancing the expression of reproduction-related genes, but its exact metabolome-related repairment mechanism of chestnut polysaccharide is still unclear. Methods and results: In this study, we studied the blood metabolomic changes of busulfan-induced asthenozoospermia-model mice before and after oral administration of chestnut polysaccharide with the help of metabolome, and screened two key differential metabolites (hydrogen carbonate and palmitic acid) from the set of metabolomic changes; we then analyzed the correlation between several metabolites and between different metabolites and intestinal flora by correlation analysis, and found that palmitic acid in the blood serum of mice after oral administration of chestnut polysaccharide had different degrees of correlation with various metabolites, and palmitic acid level had a significant positive correlation with the abundance of Verrucomicrobia; finally, we verified the role of palmitic acid in rescuing the damaged spermatogenesis process by using asthenozoospermia-model mice, and screened the key target gene for palmitic acid to play the rescuing effect by integrating the analysis of multiple databases. Discussion: In conclusion, this study found that chestnut polysaccharide rescued the damaged spermatogenesis in asthenozoospermia-model mice by upregulating palmitic acid level, which will provide theoretical basis and technical support for the use of chestnut polysaccharide in the treatment of asthenozoospermia.

Therapeutic potential of testosterone on sperm parameters and chromatin status in fresh and thawed normo and asthenozoospermic samples.

BACKGROUND: Hormonal changes alter the physiological level of ROS and cause oxidative stress in the cell. As estimated, hormonal deficiencies, environmental and ideological factors make up about 25% of male infertility. Pathogenic reactive oxygen species (ROS) is a chief cause of unexplained infertility. Limited studies exist on the effects of testosterone on human sperm culture. Therefore, in the current study, the effect of different doses of testosterone on sperm parameters and chromatin quality was investigated. MATERIALS AND METHODS: Semen samples from 15 normospermic and 15 asthenospermic patients were prepared by swim up method, and then were divided into four groups by exposing to different concentrations of testosterone (1, 10, and 100nM) for 45min. Samples without any intervention were considered as control group. All samples were washed twice. Sperm parameters and chromatin protamination were assessed in each group and the remains were frozen. After two weeks, all tests were repeated for sperm thawed. Also, the MSOM technique was used to determine the sperm morphology of class 1. RESULTS: Although sperm parameters were not show any significant differences in normospermic and asthenospermic samples exposed to different concentrations of testosterone before and after freezing, chromatin protamination was significantly decreased in the normospermic samples exposed to 10nM of testosterone before freezing (p<0.006), as well as 1 and 10nM of testosterone after freezing compared to control samples (p=0.001 and p=0.0009, respectively). Similarly, chromatin protamination in the asthenospermic samples was significantly decreased at concentration of 1nM of testosterone before and after freezing (p=0.0014 and p=0.0004, respectively), and at concentration of 10nM of testosterone before and after freezing (p=0.0009, p=0.0007) compared to control samples. CONCLUSION: Using a low dose of testosterone in the sperm culture medium, has positive effects on chromatin quality.

Qiangjing tablets ameliorate asthenozoospermia via mitochondrial ubiquitination and mitophagy mediated by LKB1/AMPK/ULK1 signaling.

CONTEXT: Therapeutic effects of Qiangjing tablets (QJT) on sperm vitality and asthenozoospermia (AZS) have been confirmed. However, the mechanism of action remains unclear. OBJECTIVE: This study investigates the effects of QJT on AZS and the underlying mechanism of action. MATERIALS AND METHODS: Sixty Sprague-Dawley rats were randomly divided into six groups: Control, ORN (ornidazole; 200 mg/kg), ORN + QJT-low (0.17 g/mL), ORN + QJT-middle (0.33 g/mL), ORN + QJT-high (0.67 g/mL), and ORN + QJT + Radicicol (0.67 g/mL QJT and 20 mg/kg radicicol) groups. Pathological evaluation and analysis of mitophagy were conducted by H&E staining and transmission electron microscopy, respectively. Reactive oxygen species were detected by flow cytometry. Protein expression was determined by Western blotting. RESULTS: QJT significantly improved ORN-treated sperm motility and kinematic parameters, as well as the pathological symptoms of testicular and epididymal tissues. In particular, QJT mitigated impaired mitochondrial morphology, and increased the PHB, Beclin-1, LC3-II protein, and ROS levels (p < 0.05), and reduced the protein expression levels of LC3-I and p62 (p < 0.05). Mechanistically, QJT antagonized the downregulation of SCF and Parkin protein levels (p < 0.05). Furthermore, QJT significantly increased the protein expressions levels of LKB1, AMPKα, p-AMPKα, ULK1 and p-ULK1 (p < 0.05). The ameliorative effect of QJT on pathological manifestations, mitochondrial morphology, and the expressions of mitophagy and mitochondrial ubiquitination-related proteins was counteracted by radicicol. DISCUSSION AND CONCLUSIONS: QJT improved AZS via mitochondrial ubiquitination and mitophagy mediated by the LKB1/AMPK/ULK1 signaling pathway. Our study provides a theoretical basis for the treatment of AZS and male infertility.

The effect of pentoxifylline and calcium ionophore treatment on sperm cell biology in oligoasthenoteratozoospermia samples.

The objective of this study was to assess the effects of pentoxifylline (PTX) and Ca2+ ionophore (CI) A12387 treatment on some biological characteristics of sperm cells in oligoasthenoteratozoospermia (OAT) patients. After processing, each sample was divided into four groups: 1, control; 2, exposed to 3.6 mM PTX; 3, exposed to 5 µm calcium ionophore (CI); and 4, exposed to both PTX and CI; 30 min at 37°C. Sperm motility was measured before and after preparation. Acrosome reaction (AR), status of sperm vacuoles, mitochondrial membrane potential (MMP) and DNA fragmentation were assessed using PSA-FITC staining, motile sperm organelle morphology examination (MSOME), JC-1 staining and sperm chromatin dispersion (CSD) test, respectively. Treatment with PTX and CI led to increased and decreased sperm motility, respectively (P < 0.05). Furthermore, vacuole status and rates of sperm DNA fragmentation were not significantly different among groups (P > 0.05). Moreover, the data showed that the rates of AR and disrupted MMP were significantly different between groups (P < 0.05). In conclusion, in vitro application of PTX not only did not have any adverse effects on sperm cell biology characteristics, but also can rectify the harmful effect of CI.

[Compound Amino Acid Capsule (8-11) combined with L-carnitine for the treatment of asthenospermia].

OBJECTIVE: To observe the clinical effect of combined application of Compound Amino Acid Capsule (8-11) (CAAC8-11) and L-carnitine (LC) in the treatment of idiopathic asthenospermia (IAS), and to explore its possible therapeutic mechanism. METHODS: Based on the principle of double-blind and control, we selected 120 cases of IAS meeting the diagnostic criteria of asthenospermia in the WHO Manual for the Examination and Processing of Human Semen (5th Ed) and randomly divided them into three groups of an equal number: CAAC8-11 + LC, LC control and blank control, the former given CAAC8-11 in addition to LC oral liquid, and the latter two given LC oral liquid and life intervention, respectively, all for 12 weeks. We collected semen samples from all the patients before and after treatment, and examined perm motility, the contents of neutral α- glucosidase (NAG) and reactive oxygen species (ROS), sperm DNA fragmentation index (DFI), and the expression of the Nrf2 protein. RESULTS: Compared with the baseline, the total sperm motility was significantly improved in the IAS patients after treated with CAAC8-11 + LC (ï¼»27.50 ± 0.77ï¼½% vs ï¼»32.50 ± 0.74ï¼½%, P < 0.05) or LC only (ï¼»27.60 ± 0.66ï¼½% vs ï¼»30.90 ± 0.70ï¼½%, P < 0.05), dramatically higher in the CAAC8-11 + LC than in the LC and blank control groups (P < 0.01). The content of NAG in the epididymis was remarkably increased after treatment in the CAAC8-11 + LC than in the LC and blank control groups (ï¼»23.90 ± 0.56ï¼½ vs ï¼»21.20 ± 0.49ï¼½ and ï¼»16.80 ± 0.42ï¼½ mU, P < 0.05), so was the expression of Nrf2 (P < 0.05), while the ROS level was markedly decreased in the former than in the latter two groups (ï¼»81.60 ± 2.50ï¼½ vs ï¼»88.50 ± 2.50ï¼½ and ï¼»88.70 ± 2.40ï¼½ µg/ml, P < 0.05). CONCLUSION: CAAC8-11 + LC has a good clinical effect on asthenospermia, with no adverse reactions, which may be attributed to its ability to regulate the high expression of Nrf2, decrease the production of ROS and reduce the damage of oxidative stress to sperm motility.

N-acetyl-l-cysteine and alpha lipoic acid are protective supplement on human sperm parameters in cryopreservation of asthenoteratozoospermia patients.

The aim of this study is to evaluate the beneficial effects of N-acetyl-cysteine (NAC), alpha lipoic acid (ALA) and combination of NAC + ALA supplement in freezing medium on Sperm structural and functional in asthenoteratozoospermia patients. Thirty freshly ejaculated semen samples were cryopreserved with sperm freezing medium (SFM) as control group and three group that SFM supplemented with NAC, ALA and their combination NAC+ ALA. The sperm samples were analysed according to WHO. Mitochondrial membrane potential (MMP), acrosome reaction (AR), antioxidant enzymes and DNA fragmentation were assessed using by Rhodamine123, PSA- FITC ELISA and TUNEL staining respectively. Expression level of NRF2 was assessed by real-time PCR assay. NAC and ALA alone significantly improved sperm motility, viability and DNA fragmentation (p < 0.05). MMP increased in NAC and ALA separately (p < 0.05). While did not affect the amount of sperm morphology and AR (p > 0.05). Antioxidant enzymes significantly difference in NAC and ALA groups (p < 0.05). In addition, NAC and ALA groups showed a significantly higher expression of NRF2 gene compared with other groups (p < 0.05). Our results revealed that the ALA and NAC supplements had a protective effect in cryopreservation process on the structural and functional characteristics of sperm.

FSH can improve semen parameters in patients with idiopathic oligoasthenoteratozoospermia: A systematic review and meta-analysis.

Follicle-stimulating hormone (FSH) is commonly used in assisted reproductive technology to promote the development and maturation of follicles in female patients. However, there is no consensus on treating FSH in males with idiopathic oligoasthenoteratozoospermia (iOAT), especially in patients with normal serum FSH levels. To determine the role of FSH in improving semen quality in patients with iOAT, we conducted a detailed search in the commonly used database to find all studies on FSH in the treatment of iOAT. We compared the results, including semen volume, sperm count, sperm concentration, percentage of forward sperm motility, percentage of total sperm motility, percentage of normal forms and DNA fragmentation index (DFI) between the two groups treated with FSH or not. A total of 12 randomized controlled trials and one retrospective case-control study, including 924 people, were included in our meta-analysis. We found that sperm counts (MD 17.75; 95% CI 11.53-23.98 and p < 0.00001) were significantly increased in patients treated with FSH, along with improvements in sperm concentration (MD 4.52; 95% CI 1.46-7.58 and p = 0.004), percentage of normal forms (MD 2.87; 95% CI 0.19-5.56 and p = 0.04) and DFI (MD -12.62; 95% CI -19.27-5.97 and p = 0.002). However, we found no significant differences in the two groups' changes in other semen parameters. The use of FSH can improve some semen parameters in patients with iOAT, such as sperm count, percentage of normal forms, sperm concentration and DFI.

GM-CSF (granulocyte-macrophage colony-stimulating factor) treatment improves sperm parameters in men with oligoasthenoteratospermia via PI3K/AKT pathway.

Poor sperm quality in oligoasthenoteratospermia patients negatively affects assisted reproductive technology outcomes. Therefore, the development of sperm media is necessary to improve sperm parameters. This study investigated the effect of GM-CSF via PI3K/AKT pathway on sperm quality in OAT patients. Semen samples were collected from 20 OAT patients, and each sample was divided into two groups: Experiment and Control. In the experimental group, the samples were incubated with medium containing GM-CSF, and control samples were incubated without GM-CSF. Sperm parameters, mitochondrial membrane potential, acrosome reaction and DFI were studied; in addition, gene expression of PI3KR1, PI3KCA, GLUT1, GLUT3 and AKT1 was analysed, evaluation of PAKT/TAKT, and expression of GLUT 1, 3 was examined; subsequent fertilization rate and embryo quality were assessed. Our data showed that GM-CSF supplementation could significantly increase motility, mitochondrial activity, gene expression of PI3KCA, AKT1, the protein level of PAKT/TAKT and expression of GLUT 1, 3 while it decreases DNA fragmentation. The fertilization rate and embryo quality significantly improved in the treatment group. LY294002 had adverse effects on sperm motility and the PAKT/TAKT ratio. GM-CSF can improve in vitro sperm quality and could be a suitable supplement to sperm media for OAT patients.
