The Effect of Carob (Ceratonia Siliqua) on Sperm Parameters of Infertile Men: Systematic Review and Meta-Analysis of Randomized Controlled Trials

Carob (Ceratonia siliqua) supplements can increase sperm quality. This study aimed to summarize the available evidence about the effects of carob (Ceratonia siliqua) supplements on sperm quality and reproductive hormones in infertile men. Systematic searches of five databases were conducted from inception to October 20, with the last update on November 20, 2023. Randomized clinical trials (RCTs) that compared carob (Ceratonia siliqua) supplements with nonintervention control groups on infertile man. Risk of bias and certainty of evidence were assessed by the Cochrane risk of bias tool 2. Summary effect size measures were calculated using a random-effects model estimation and are reported as standardized mean differences and 95% confidence intervals. Reporting followed the PRISMA guidelines. The analysis included four studies involving 236 infertile men. It was found that sperm motility of infertile men improved after carob intervention (MD:11.30, 95% CI:5.97 to 16.64, Z = 4.15, p < 0.00001), and there was a significant difference compared to control groups. The effect size of carob on semen quantity in infertile men was positive, and the relationship was statistically significant (MD:5.42, 95% CI:1.58 to 9.42, Z = 2.77, p = 0.006). When hormone parameters of infertile men were analyzed, the MDA (malondialdehyde) value decreased compared to the control group (MD = -4.81, 95% CI: -10.18 to 0.56, Z = 1.76, p = 0.08), and there was a significant difference between them. Carob (Ceratonia siliqua) supplements was associated with improvement in sperm quality compared with nonintervention control groups in infertile man. However, high-quality, larger RCTs are required to draw more definitive conclusions.

Does acupuncture improve sexual dysfunction? A systematic review

OBJECTIVES

Sexual dysfunction can adversely affect the quality of life and interpersonal relationships. nowadays, a lot of attention is paid to traditional Chinese medicine with better curative effects and less adverse events. Recent studies have implied the promising effect of acupuncture on sexual function. This systematic review evaluate the effectiveness and safety of acupuncture in treating female and male sexual dysfunction.

CONTENT

No limitation to language and date. The methodological quality of the studies was assessed using the Mixed Methods Appraisal Tool (MMAT).

SUMMARY

Among 160 initially assessed papers, 13 articles were included. The findings showed that acupuncture improve sexual dysfunction in domains of desire, libido, erectile dysfunction and impotency. Most studies did not report any serious side effects from acupuncture, and only three studies reported minor adverse events.

OUTLOOK

The available evidence indicate that acupuncture has positive on improvement of sexual dysfunction with no serious side effects. Although acupuncture has gained increasing popularity for the management of sexual dysfunction, high methodological quality evidence regarding its efficacy is lacking.

Electromagnetic fields exposure on fetal and childhood abnormalities: Systematic review and meta-analysis

Today, in the modern world, people are often exposed to electromagnetic waves, which can have undesirable effects on cell components that lead to differentiation and abnormalities in cell proliferation, deoxyribonucleic acid (DNA) damage, chromosomal abnormalities, cancers, and birth defects. This study aimed to investigate the effect of electromagnetic waves on fetal and childhood abnormalities. PubMed, Scopus, Web of Science, ProQuest, Cochrane Library, and Google Scholar were searched on 1 January 2023. The Cochran's Q-test and I ² statistics were applied to assess heterogeneity, a random-effects model was used to estimate the pooled odds ratio (OR), standardized mean difference (SMD), and mean difference for different outcomes, and a meta-regression method was utilized to investigate the factors affecting heterogeneity between studies. A total of 14 studies were included in the analysis, and the outcomes investigated were: change in gene expression, oxidant parameters, antioxidant parameters, and DNA damage parameters in the umbilical cord blood of the fetus and fetal developmental disorders, cancers, and childhood development disorders. Totally, the events of fetal and childhood abnormalities were more common in parents who have been exposed to EMFs compared to those who have not (SMD and 95% confidence interval [CI], 0.25 [0.15-0.35]; I ², 91%). Moreover, fetal developmental disorders (OR, 1.34; CI, 1.17-1.52; I ², 0%); cancer (OR, 1.14; CI, 1.05-1.23; I ², 60.1%); childhood development disorders (OR, 2.10; CI, 1.00-3.21; I ², 0%); changes in gene expression (mean difference [MD], 1.02; CI, 0.67-1.37; I ², 93%); oxidant parameters (MD, 0.94; CI, 0.70-1.18; I ², 61.3%); and DNA damage parameters (MD, 1.01; CI, 0.17-1.86; I ², 91.6%) in parents who have been exposed to EMFs were more than those in parents who have not. According to meta-regression, publication year has a significant effect on heterogeneity (coefficient: 0.033; 0.009-0.057). Maternal exposure to electromagnetic fields, especially in the first trimester of pregnancy, due to the high level of stem cells and their high sensitivity to this radiation, the biochemical parameters of the umbilical cord blood examined was shown increased oxidative stress reactions, changes in protein gene expression, DNA damage, and increased embryonic abnormalities. In addition, parental exposure to ionizing and non-ionizing radiation can lead to the enhancement of different cell-based cancers and developmental disorders such as speech problems in childhood.

Herbal interventions pose a popular alternative for the treatment of infertility. However, much has to be learned regarding their safety and efficacy. Objective: The aim of the study was to investigate the efficacy of herbal interventions in male infertility and also assess the possibility of these interventions as complementary and alternative medicine (CAM) in the future. Method: From inception until 16 December 2021, all articles emphasizing the efficacy of herbal interventions in the treatment of male infertility are included in this review. Seven databases are searched. The literature obtained is screened and extracted. Semen parameters, hormonal concentration, and conception are the outcomes of interest. Results: A total of 19 articles were included in this review. Herbal interventions might improve semen parameters in males with infertility. Among all the interventions, Hochu-ekki-to and W. somnifera have shown the most promising results and should be studied further in a larger sample size. Conclusion: This systematic review has demonstrated the efficacy of herbal interventions, especially Hochu-ekki-to and W. somnifera, in treating male infertility.

A Systematic Review on Use of Medicinal Plants for Male Infertility Treatment

Objective: Male infertility is involved in about half of the casess of infertility and the only sole reason for infertility in 20%-30% of the cases. Following the recent interest in the use of medicinal plants, scientists have sought to clarify their effects on male fertility. This review aimed to summarize the results of studies available to determine the effectiveness, safety and mechanism of herbal treatments in the improvement of male fertility.

Materials and methods: Medline/PubMed, Scopus, Science Direct, and the Cochrane Central Register of Controlled Trials (Central) databases were searched for randomized controlled trials (RCTs) published during 2000-2020. Studies were only included if they adhered to the CONSORT checklist. The methodological quality of the selected studies was assessed using the Cochrane risk of bias tool.

Results: Finally, 20 studies recruiting a total of 1519 individuals were reviewed. These studies compared the effects of eleven different medicinal plants, i.e. ginseng, saffron, Nigella sativa, palm pollen, ADOFON, TOPALAF, sesame, and Mucuna pruriens, on male fertility with those of placebo. All studies (except one) confirmed the beneficial effects of medicinal plants on the improvement of sperm and reproductive parameters and thus male infertility.

Conclusion: The existing RCTs indicated the positive effects of medicinal plants on male fertility. Therefore, in order to develop a novel approach to the treatment of male infertility, further clinical trials are warranted to determine the maximum dosage and duration of treatment with herbal medicines and evaluate any potential side effects of such interventions.

Labor Pain in Different Dilatations of the Cervix and Apgar Scores Affected by Aromatherapy: A Systematic Review and Meta-analysis

Labor pain (LP), as a physiological process, is known as one of the most severe pains. Aromatherapy is one of the methods to reduce LP in the first phase of labor. It is an important approach for enjoyable birth and decreases the severity of pain in today's society. Accordingly, this study aimed to systematically review the relieving effect of aromatherapy in LP and Apgar score. We used international databases such as EMBASE, Web of Science, Scopus, Google Scholar, PubMed, Cochrane Library, ProQuest, and clinicaltrials.gov to conduct a systematic search for all relevant articles. Cochran's Q-test and I² statistic were applied to assess heterogeneity, a random-effects model was used to estimate the unstandardized mean difference (UMD), and a meta-regression method was utilized to investigate the factors affecting heterogeneity between studies. A total of 27 studies were included in the meta-analysis (sample size: 2,566). Overall, aromatherapy leads to relieving LP during delivery (UMD: 1.75; 95% CI: 1.13-2.37). Based on cervix dilation, aromatherapy significantly affects LP when cervix dilation is 8-10 cm (UMD: 6.18; 95% CI: 4.51-7.85) and 0-4 cm (UMD: 5.31; 95% CI: 3.74-6.87); but it had no effects on 1- and 5-min Apgar scores. No publication bias was observed (P=0.113). Mother's age, publication year, sample size, and cervix dilation had no significant effects on heterogeneity (P>0.05). Aromatherapy had a positive impact on relieving LP, and the greatest and least effect was witnessed in dilatation of 8-10 cm and 0-4 cm, respectively. Moreover, it had no effects on 1- and 5-min Apgar scores.

Sexual dysfunction among women of reproductive age: A systematic review and meta-analysis

Background

Available statistics show a high prevalence of sexual dysfunction (SD) among women worldwide. Various factors affect SD among women of reproductive age.

Objective

To evaluate studies on the prevalence and determinants of SD in different parts of the world.

Materials and Methods

MEDLINE, EMBASE, Web of Science, Scopus and ProQuest databases were systematically reviewed during 2000–2019. All original articles were reviewed. The STROBE checklist was used to evaluate the quality of the papers. I2 was calculated to determine heterogeneity. Fixed effects and/or random-effects models were applied to estimate the pooled prevalence. Meta-regression analysis was also performed to identify the sources of heterogeneity.

Results

Based on the results of the meta-analysis (21 eligible studies), the pooled prevalence with 95% confidence interval of SD was estimated at 50.75% (41.73–59.78). The prevalence of pain and disorders in arousal, sexual desire, lubrication, orgasm, and sexual satisfaction were calculated (39.08%, 48.21%, 50.70%, 37.60%, 40.16%, and 35.02%, respectively). Also, age, depression, low education level, increased duration of the marriage, and the presence of chronic diseases were the highest risk factors for SD.

Conclusion

The prevalence of SD in women of reproductive age varies in different countries. Considering the importance of female SD, further studies are needed to facilitate the development of relevant educational interventions.

Therapeutic Potential of Date Palm against Human Infertility: A Review

Male and female infertility is a global major health problem. Approximately 15% of couples of a reproductive age are unable to achieve the desired pregnancy within 12 months, despite daily unprotected sexual intercourse, and about 10% of infertilities have no specific reason worldwide. Currently, many researchers are interested to investigate the use of natural remedies for preventive and curative purposes of infertility. This review brings together some of the data on the nutritional characteristics of the date palm and its different parts on fertility outcomes and critically evaluates the past and recent literature relevant to the consumption of date fruit against infertility-related problems. Due to its antioxidant potential, dates are considered a functional treatment for reducing the risks of infertility. In males, the date palm has a potent effect on the reproductive parameters including hormonal levels and seminal vesicle parameters as well as sperm motility, count, and viability; whereas, in females, it shows a convincing effect on reproductive parameters including oogenesis process, strengthening of oocytes, regulation of hormones, strengthening of pregnancy, reduction of the need for labor augmentation, and postpartum hemorrhage prevention.

Role of cesarean section in the development of neonatal gut microbiota: A systematic review

Background

The delivery mode is one of the factors affecting the type of colonization of the human gut. Gut colonization affects all stages of the human life cycle, and the type of gut microbiome can contribute to immune system function, the development of some diseases, and brain development; and it has a significant impact on a newborn’s growth and development.

Methods

Terms defined as MeSH keywords were searched by the databases, and web search engines such as PubMed, ClinicalTrials.gov, Embase, Scopus, ProQuest, Web of Science, and Google Scholar were searched between 2010 and 2020. The quality of each study was assessed according to the Newcastle–Ottawa scale, and seven eligible and high-quality studies were analyzed.

Finding

The abundances of Bacteroides and Bifidobacterium during the first 3 months of life; Lactobacillus and Bacteroides during the second 3 months of life; Bacteroides and Bifidobacterium during the second 6 months of life; and Bacteroides, Enterobacter, and Streptococcus after the first year of life were higher in vaginal delivery-born infants. While infants born by cesarean section (CS) had higher abundances of Clostridium and Lactobacillus during the first 3 months of life, Enterococcus and Clostridium during the second 3 months of life, and Lactobacillus and Staphylococcus after the first year of life.

Discussion

Delivery mode can affect the type of the human intestinal microbiota. The CS-born babies had lower colonization rates of Bifidobacterium and Bacteroides, but they had higher colonization rates of Clostridium, Lactobacillus, Enterobacter, Enterococcus, and Staphylococcus. Given the effect of microbiota colonization on neonatal health, it is therefore recommended to conduct further studies in order to investigate the effect of the colonization on the delivery mode and on baby’s growth and development.

Application to practice

The aim of this study was to investigate the role of CS in the development of the neonatal gut microbiota.

Social determinants of domestic violence against suburban women in developing countries: a systematic review

OBJECTIVE

In addition to the many social, economic, cultural, security, and environmental problems in the metropolitan areas, suburbanization has led to the growth and spread of domestic violence against women, and is still increasing. Different social determinants can play a role in violence against suburban women, so this study was designed to investigate the social determinants of domestic violence in suburban women of developing countries.

METHODS

According to PRISMA guideline, the keywords, which were determined considering MESH, were searched in Google Scholar, MEDLINE, SID, Web of Science, Pubmed, Scopus and Science Direct with the 2009 to 2019 time limit. STROBE checklist was used for evaluating quantitative studies and JBI for qualitative studies. Finally 30 high quality studies were included.

RESULTS

The prevalence of general domestic violence among women of different ages was reported between 2.3-73.78% in the suburban regions of developing countries. The prevalence of physical, emotional and psychological violence was about 11.54-61.6% and 7.8-84.3%. The prevalence of sexual,economic and the verbal violence was about 0.8-58.8%, 13.7- 43.7% and 33.21-86.1%. The most common factors affecting violence against women were the structural factors of early marriage, the husband's addiction to alcohol and drugs.

CONCLUSION

General domestic violence and its various types are prevalent in different parts of the world and the factors affecting domestic violence such as age, marriage age, low literacy, husband addiction to alcohol and drugs are all things that can be prevented by special health planning in these areas to improve women's health and thus prevent violence against suburban women.

Efficacy of Herbal Based Syrup on male sexual experiences: A double-blind randomized clinical trial

Background and aim

An Aphrodisiac includes any drug and food that arouses sexual instinct, induces venereal desire, and increases pleasure and performance. The present study was designed to clinically evaluate efficacy and safety of Herbal Based Syrup (HBS) composed of Tribulus terrestris L., Panax ginseng C.A. Meyer., Zingiber officinale Rosc, Ceratonia siliqua L., Papaver rhoeas L., and Palm tree pollen on sexual experience of men.

Experimental procedure

The study was designed as a double-blind randomized clinical trial. The main outcome measures were the responses obtained from using the Arizona Sexual Experience Scale (ASEX). The ASEX was completed by 100 married and seemingly healthy men before and after taking one dose of HBS or placebo and at least one sexual intercourse. In addition, possible side effects were observed. A split-plot ANOVA (SPANOVA) design was used for statistical analysis.

Results

Results of analysis of data for each variable of the ASEX showed significantly lower scores in HBS-treated group compared to the placebo (control) group in items of desire, arousal, erection, orgasm and satisfaction (p < 0.05). No drug-related serious adverse events were observed.

Conclusion

Results of this study indicated a significant improvement in sexual experience of men following consumption of HBS. Due to various complications reported about the use of chemical sexual drive enhancers, HBS can be introduced as an alternative with fewer side effects.

•

The syrup enhances sexual desire, arousal, erection, orgasm and satisfaction.

•

The syrup may be a useful supplement to improve sexual experience of healthy men.

•

The syrup was stable more than 1 year in room temperature.

Anti-hypercholesterolemic impacts of barley and date palm fruits on the ovary of Wistar albino rats and their offspring

A high cholesterol diet is related to ovarian dysfunction and infertility which has been increased among young ages consuming processed food products. The present study was conducted to evaluate the role of a high cholesterol diet on the ovaries of young female rats via assessments of histopathology, immunohistochemistry, oxidative stress and apoptic markers. Also, mating of hypercholesterolemic female rats was carried out to measure the fertility and numbers of their offspring. At the same time, phytotherapy was carried out through supplementing the diet with barley and/ or date palm fruits (10%) during the experiment to assess the phyto-therapeutic impacts in attenuation of drastic hypercholesterolemic effects. Hypercholesterolemic diet-fed rats exhibited damage of the ovarian follicles and increased follicular atresia. Furthermore, expression of cleaved caspase-3 was upregulated, while PCNA was downregulated in granulosa, theca and stroma cells. Hypercholesterolemic female rats showed marked depletion of antioxidative enzymes, increased lipid peroxidation and apoptotic markers. Alterations to the female serum hormones were detected. Offspring maternally fed on hypercholesterolemic diet showed a significant decrease of body weight and altered sex ratio. However, concomitant supplementation of barley and or date fruits to hypercholesterolemic groups revealed marked improvement of ovarian structure and function. On the basis of these evidences, it is believed that the enhanced synergistic effects of barley and/or date palm fruits in the amelioration of ovarian structure and functions were elicited by the potential antioxidant activity of their phytomicronutrients, polyphenols, β-glucan and trace elements. These materials scavenge free radicals from inflamed cells that can be used to establish an effective and novel therapeutic strategy for activating ovarian cell regeneration.

Comparative in vitro/theoretical studies on the anti-angiogenic activity of date pollen hydro-alcoholic extract: Highlighting the important roles of its hot polyphenols

Introduction: Date palm pollen (DPP) is the male reproductive soft powder from date flowers widely used as the valuable dietary supplement to fortify the size of testis and ovarian to increase the power of sex. This part of date palm significantly exhibited anti-diabetic, anti-inflammation and protective effects against male and female infertility. Though the anticancer activity of date fruits was previously reported, the DPP anti-angiogenic effects were not reported, and as the first study, its inhibitory effects were examined in the current study.

Methods: The DPP soft powder was collected to prepare its hydro-alcoholic extract to examine its anti-angiogenic activity in an in vitro model. At different concentrations, the cytotoxicity of the prepared extract was examined on human umbilical vein endothelial cells (HUVECs) using lactate dehydrogenase method. Cell proliferation was determined using the MTT assay and cytodex-3D model in collagen gel was used to assay its possible anti-angiogenic activity. The expression of VEGF, MMP-2 and MMP-9 genes was measured using real-time polymerase chain reaction (PCR). Finally, molecular docking simulation was used to highlight the possible role of DPP polyphenols to interact with the associated receptors.

Results: The prepared hydro-alcoholic extract exhibited significant anti-angiogenic activity in a dose-dependent manner and decreased the endothelial cell proliferation. The calculated IC₅₀ value for the examined extract in angiogenesis model was 260 µg·mL, respectively. Also, the expression of VEGF, MMP-2 and MMP-9 genes were significantly decreased. Docking simulation results unveiled that the isolated DPP polyphenols have the affinity to interact with ctDNA, VEGF and its receptors.

Conclusion: The DPP is the new source of non-toxic anti-cancer agents to use as a dietary supplement in the pre-treatment of cancer.
