The impact of epigenetic modifications like DNA methylation on plant phenotypes has expanded the possibilities for crop development.DNA methylation plays a part in the regulation of both the chromatin structure and gene expression,and the enzyme involved,DNA methyltransferase,executes the methylation process within the plant genome.By regulating crucial biological pathways,epigenetic changes actively contribute to the creation of the phenotype.Therefore,epigenome editing may assist in overcoming some of the drawbacks of genome editing,which can have minor off-target consequences and merely facilitate the loss of a gene’s function.These drawbacks include gene knockout,which can have such off-target effects.This review provides examples of several molecular characteristics of DNA methylation,as well as some plant physiological processes that are impacted by these epigenetic changes in the plants.We also discuss how DNA alterations might be used to improve crops and meet the demands of sustainable and environmentally-friendly farming. 展开更多

Objective:To explore the impact of Ficus carica fruit aqueous extract on fertility parameters in streptozotocin(STZ)-induced male rats.Methods:Twenty-four male Sprague-Dawley rats were divided into four different groups.All groups except a normal control group were induced with 50 mg/kg of streptozotocin(STZ)intravenously to induce diabetes.A positive control group was treated with an antidiabetic drug,metformin(500 mg/kg)whereas a negative control group remained untreated throughout the experiment.Meanwhile,another diabetic rat group received treatment with 400 mg/kg of aqueous Ficus carica fruit extract.Rats in the treatment group were administered Ficus carica fruit aqueous extract daily through forcefeeding via oral gavage for a 21-day period.Assessments included the sperm quality(count,motility and morphology),histology of the testes,serum testosterone and fasting blood glucose(FBG)level.Results:The FBG level of the Ficus carica-treated rats exhibited a significant decrease compared to the negative control group(P<0.05).Sperm quality analysis also indicated that the aqueous Ficus carica extract had significant positive effects on sperm count and motility(P<0.05).The histology of the testes in Ficus caricatreated rats revealed an improved cell arrangement in the germinal cell layer.Furthermore,serum testosterone level showed an increment in the Ficus carica treatment group in comparison to the negative control group.Conclusions:Our findings provide compelling evidence for the profertility and anti-hyperglycemic properties of aqueous Ficus carica fruit extract in diabetic-induced male rats. 展开更多

Infertility is of male origin in 40% of cases. Our objective was to evaluate the epidemiological and clinical aspects of male infertility in our setting. Methods: This was a cross-sectional and descriptive study, with retrospective data collection from the files of patients received for male infertility, over 5 years and 6 months (from January 1<sup>st</sup>, 2016 to April 30<sup>th</sup>, 2021) at the Urology Department of the Yaounde Central Hospital. Phone calls were made to patients with incomplete records for completion following a verbal consent. Data reported on data collection forms were entered into a data entry form designed on CSPro software version 7.2. The database was later exported for descriptive statistics using the IBM SPSS software version 23. Qualitative variables were summarized in frequencies and percentages while quantitative variables were summarized in means with their standard deviations for normally distributed data, or medians and interquartile ranges otherwise. Results: Out of 110 patients whose records were analyzed, the median age was 37.0 years, with an interquartile range of 8.3, with 55.5% in the age group 30 to 39 years. Of these 95 (86.4%) were married, 58 (52.7%) were from the West region, 76 (69.1%) were employed. Past history was dominated by mumps 40 (36.4%), varicocele surgery 25 (22.7%), alcoholism 87 (79.1%) and smoking 15 (13.6%). A disorder of spermatogenesis was found in all our patients: 37 (33.6%) azoospermia, 27 (24.6%) asthenospermia and 26 (23.7%) oligospermia patients. Paraclinical evidence of chlamydia and gonococcal infections were found respectively in 38 (34.5%) and 14 (12.7%) patients, varicocele and testicular dystrophy respectively in 95 (86.4%) and 38 (34.5%) patients. Infertility was primary in 67 (60.9%) patients. Conclusion: Most patients with infertility were in their thirties, had risky social habits and comorbidities. An early start of health promotion activities, comorbidities prevention and early detection of spermogram abnormalities would make it possible to reduce the frequency of male infertility. 展开更多

But effective therapeutic solutions to pesticide related male infertility are yet to be established. This study investigated the curative effects of Lannea acida on imidacloprid (IMI)-induced hypofertility in male Wistar rats. Methods: Rats of 150 – 200 g were administered IMI (22.5 mg/kg) for two weeks and partitioned into control (distilled water, vitamin E, clomiphene citrate) or test (aqueous (340 mg/kg), methanol (170 mg/kg) extract) groups for eight weeks treatment. Animals were sacrificed at the end of the treatment and samples were collected for sperm, antioxidant and hormonal analysis. Fertility tests were performed from treatment day 47 for fertility indices estimation. Results were expressed as mean ± SEM and one way ANOVA was applied using STATISTICA Software. Results: Exposition to IMI resulted in a significant decrease in sperm count, motility, viability and normality, testosterone and LH, coupled to an increase in oxidative stress markers. Moreover, IMI impaired male fertility evidenced by a significant drop in fertility index and litter size. Similar to clomiphene citrate and vitamin E, plant extracts significantly improved the sperm parameters, sexual hormones and decreased the oxidative stress markers. More importantly, the fertility index and litter size were restored, especially with the aqueous extract. Conclusion: Present results indicate that L. acida possesses curative potentials against IMI-induced hypofertility through its androgenic and antioxidant properties. However, the effects the extract on spermatozoa DNA structure and the fertility of offsprings from exposed parents are yet to be studied to conclude on total recovery from IMI toxicity. 展开更多

It has been well known for many years that males of Luciola parvula (Coleoptera, Lampyridae) have two morphs, namely small and large morphs in Japan. This article performed a statistical reanalysis of their morphological measurements based on previously published data and compared them. As a result, the two morphs were found to have different allometric patterns in the Hakone and Nagano areas, Japan. In Hakone, the relationships between their pronotum width and length were expressed by a common allometric line and a shift in location along the line. However, in Nagano, the relationships between their pronotum width and body length were expressed by two parallel allometric lines (a common slope and different intercepts). The allometric pattern of males of this species may vary among different parts of the body or among different areas. Therefore, this article recommends future studies to measure the same parts of the body as previous studies to clarify geographic variation in allometric relationships. 展开更多

Introduction: Mechanism of male androgenic alopecia (MAGA) is complex and leads to an excessive hair shedding and decreased hair density. Oral, topical, and injectable autologous treatments demonstrate ability to stimulate hair re-growth, but the response is suboptimal or plateaus off. Synthetic combination of the peptide complex and hyaluronic acid (P-HA) demonstrated hair regrowth in alopecia patients. Electronically-operated pneumatic injections (EPI) generate micro-trauma in the dermis and under wound-healing conditions may enhance regeneration effect of P-HA. Methods: Subjects seeking improvement of their male pattern hair loss (Hamilton-Norwood type 2-4) received the P-HA treatments through EPI. The course included 4 treatments every two weeks over the 8-week period. In 6 months, the hair growth was assessed comparative to baseline by global clinical photography and digital phototrichograms. The treatment safety and tolerability were documented through the whole study period. Results: Twelve men (30-45 years old) completed the treatment course with high tolerability and without adverse events. Post-treatment assessment of the previously bald areas showed improved coverage on the clinical photographs. The phototrichograms demonstrated statistically significant increase in terminal hair density by 36%, cumulative hair thickness by 37%, and follicular units by 20%;all contributing to a 38% increase in cumulated hair density (all p Conclusion: Electronic pneumatic injections are well tolerated and can be safely used for the needle-free administration of the peptide-hyaluronic acid combination in MAGA therapy. We achieved significant hair re-densification in the balding scalp. The exact role of the EPI-induced impact in the hair re-growth mechanism remains to be ascertained. . 展开更多

Exploring genetic mechanism of the first female flower node and the first male flower node in bitter gourd has practical significance for formulating breeding strategy. In this article, a cross was made between CN19-1 and Thai4-6, and the F2segregation population was also constructed through F1selfing. The genetic characteristics of the first female flower node and the first male flower node were analyzed by adopting the major gene plus polygene mixed genetic model. The data analysis results showed that the first female flower node and the first male flower node were continuous distribution in the F2segregation population. E-2 model was the most suitable model for the genetic analysis of the first female flower node and the first male flower node. The additive effect values of the 2 pairs of major genes controlling the first female flower node were 2.722 and 1.862 8 respectively, the dominant effect values were-2.721 6 and-0.171 8, respectively. The additive effect value of polygene was-0.839 2, and the dominant effect value of polygene was 2.225 4. The heritability of major genes and polygene were 83.73% and 1.54%, respectively. The additive effect values of the 2 pairs of major genes controlling the first male flower node were 17.746 9 and 3.972, respectively, the dominant effect values were 5.191 6 and-3.972, respectively. The additive effect value of polygene was-20.530 5, and the dominant effect value was-4.141 4. The heritability of major genes and polygene was 92.34% and 4.7%, respectively. This study could provide a theoretical basis for bitter gourd breeding. 展开更多

Background Comparative and comprehensive omics studies have recently been conducted to provide a comprehensive understanding of the biological mechanisms underlying infertility.However,because these huge omics datasets often contain irrelevant information,editing strategies for summarizing and filtering the data are necessary prerequisite steps for identifying biomarkers of male fertility.Here,we attempted to integrate omics data from spermatozoa with normal and below-normal fertility from boars and bulls,including transcriptomic,proteomic,and metabolomic data.Pathway enrichment analysis was conducted and visualized using g:Profiler,Cytoscape,EnrichmentMap,and AutoAnnotation to determine fertility-related biological functions according to species.Results In particular,gamete production and protein biogenesis-associated pathways were enriched in bull spermatozoa with below-normal fertility,whereas mitochondrial-associated metabolic pathways were enriched in boar spermatozoa with normal fertility.These results indicate that below-normal fertility may be determined by aberrant regulation of protein synthesis during spermatogenesis,and the modulation of reactive oxygen species generation to maintain capacitation and the acrosome reaction governs boar sperm fertility.Conclusion Overall,this approach demonstrated that distinct molecular pathways drive sperm fertility in mammals in a species-dependent manner.Moreover,we anticipate that searching for species-specific signaling pathways may aid in the discovery of fertility-related biomarkers within large omics datasets. 展开更多

Callose contributes to many biological processes of higher plants including pollen development,cell plate and vascular tissue formation,as well as regulating the transport function of plasmodesmata.The functions of callose synthase genes in maize have been little studied.We describe a maize male-sterile mutant 39(ms39)characterized by reduced plant height.In this study,we confirmed using CRISPR/Cas9 technology that a mutation in Zm00001d043909(ZmCals12),encoding a callose synthase,is responsible for the male sterility of the ms39 mutant.Compared with male-fertile plants,callose deposition around the dyads and tetrads in ms39 anthers was significantly reduced.Increased cell autophagy observed in ms39 anthers may have been due to the premature programmed cell death of tapetal cells,leading to collapse of the anther wall structure.Disordered glucose metabolism in ms39 may have intensified autophagy in anthers.Evaluation of the ms39 gene on maize heterosis by paired-crossed experiment with 11 maize inbred lines indicated that ms39 can be used for maize hybrid seed production. 展开更多

Plant male reproduction is a fine-tuned developmental process that is susceptible to stressful environments and influences crop grain yields.Phytohormone signaling functions in control of plant normal growth and development as well as in response to external stresses,but the interaction or crosstalk among phytohormone signaling,stress response,and male reproduction in plants remains poorly understood.Cross-species comparison among 514 stress-response transcriptomic libraries revealed that ms33-6038,a genic male sterile mutant deficient in the Zm Ms33/Zm GPAT6 gene,displayed an excessive drought stress-like transcriptional reprogramming in anthers triggered mainly by disturbed jasmonic acid(JA)homeostasis.An increased level of JA appeared in Zm Ms33-deficient anthers at both meiotic and postmeiotic stages and activated genes involved in JA biosynthesis and signaling as well as genes functioning in JA-mediated drought response.Excessive accumulation of JA elevated expression level of a gene encoding a WRKY transcription factor that activated the Zm Ms33 promoter.These findings reveal a feedback loop of Zm Ms33-JA-WRKY-Zm Ms33 in controlling male sterility and JA-mediated stress response in maize,shedding light on the crosstalk of stress response and male sterility mediated by phytohormone homeostasis and signaling. 展开更多

Background and Objectives: Chronic low-dose exposure to dichlorvos occurs in communities in Africa where the substance is used indiscriminately for a variety of purposes. This experiment used an animal model to evaluate genomic instability induced by this pattern of chronic exposure and its relationship with some measures of fertility in males. Methods: Seventy-five male Rattus norvegicus rats obtained for this experiment, were randomly allotted into five groups. Dichlorvos was given by oral gavage at doses of 0.28 mg/kg, 0.56 mg/kg and, 1.68 mg/kg, respectively, to three of the groups, on alternate days for 50 weeks. The remaining two groups received plain drinking water and cyclophosphamide as negative and positive controls, respectively. Samples were collected at 17, 34, and 50 weeks. Sperm count, sperm morphology and serum levels of follicle-stimulating hormone, luteinizing hormone, dihydrotestosterone, oestrogen and progesterone were determined. Furthermore, the frequency of micronucleated polychromatic erythrocytes was determined in bone marrow cells obtained from the femur. Results: The mean ranks of micronuclei frequency had an increasing trend. The frequency of micronucleated polychromatic erythrocytes (MnPCE) had a significant negative correlation with oestrogen (r<sub>s</sub> = -0.47, p = 0.00, n = 50), follicle-stimulating hormone (r<sub>s</sub> = -0.41, p = 0.00, n = 50) and progesterone (r<sub>s</sub> = -0.37, p = 0.01, n = 50) serum levels. A positive monotonic relationship also existed between micronuclei frequency and those of tubular necrosis, tubular vacuolation, and residual bodies. A positive significant moderate correlation was found between MnPCE and the proportion of immotile sperms (r<sub>s</sub> = 0.41, p = 0.00, n = 50). Conclusion: The nature of the correlations between micronuclei frequency and the proportion of immotile sperms, adverse histological changes and serum hormone levels found in this study suggest genomic instability as the possible mechanism for diminished fertility in males chronically exposed to dichlorvos. 展开更多

Background: The synergistic mixture of Cyperus esculentus, Phoenix dactylifera and Cocos nucifera (STCD) aqueous extract is a common drink in Port Harcourt, Nigeria. It is assumed to have various health benefits. However, the synergistic mixture of the content has not been studied scientifically, hence the need to evaluate its effect on the liver and kidney being part of the body’s metabolic organs. Aim: This study evaluated the synergistic mixture of Cyperus esculentus, Phoenix dactylifera and Cocos nucifera (STCD) aqueous extract in male albino rats. Methods: Acute toxicity LD<sub>50</sub> of STCD was carried out, afterwards, fifteen male albino rats were grouped into three groups with 5 rats in each group;Control, 200 mg/kg, 400 mg/kg STCD. The rats were administered STCD orally 24 hourly, for 21 days, with feed and water ad libitum. At the end of the experiment, blood samples were collected for biochemical analysis of the liver and kidney biomarkers, while the liver and kidney tissues were harvested for histopathological examination using standard laboratory methods. Descriptive statistics were computed and expressed as Mean ± SD. One-way ANOVA and Turkeys test was performed. P value ≤0.05 was considered statistically significant. Results: Acute toxicity LD50 of STCD was observed to be ≥2404.2 mg/kg body weight. An increase in the percentage body weight difference of 8.39% and 2.86% was observed for 200 and 400 mg/kg STCD groups. Also, the liver weight was observed to increase in 400 mg/kg (3.92 ± 1.42) in comparison to the control group (3.48 ± 1.61), a decrease in the kidney weight was observed in all groups administered STCD in comparison to the control group. Administration of STCD at both 200 and 400 mg/kg revealed a decrease in the concentration of the hepatic biomarkers AST, ALT, ALP, TP, Albumin, Total and conjugated bilirubin. The kidney biomarker Urea was observed to decrease in concentration for 200 mg/kg STCD (4.60 ± 1.83) and 400 mg/kg STCD (4.76 ± 0.74) when compared to the control group (6.32 ± 2.74). A decrease in Creatinine was observed in 200 mg/kg (91.80 ± 34.69) and 400 mg/kg (98.60 ± 15.53) in comparison to the control group (117.60 ± 42.88). The histological examination of the liver of rats administered STCD revealed structural normal central vein, hepatocytes and portal tract. The kidney examination revealed normal glomeruli and normal tubule. Conclusion: The findings of this study opine that STCD improved the health of both the liver and kidney as evidenced via the biomarkers and histological examinations of the liver and kidney. This study therefore recommends the intake of STCD at moderate doses for improved liver and kidney function due to its bioactive compounds and nutritional content. 展开更多

The British Medical Association(BMA)guidance on non-therapeutic circumcision(NTMC)of male children is limited to ethical,legal and religious issues.Here we evaluate criticisms of the BMA’s guidance by Lempert et al.While their arguments promoting autonomy and consent might be superficially appealing,their claim of high procedural risks and negligible benefits seem one-sided and contrast with high quality evidence of low risk and lifelong benefits.Extensive literature reviews by the American Academy of Pediatrics and the United States Centers for Disease Control and Prevention in developing evidence-based policies,as well as risk-benefit analyses,have found that the medical benefits of infant NTMC greatly exceed the risks,and there is no reduction in sexual function and pleasure.The BMA’s failure to consider the medical benefits of early childhood NTMC may partly explain why this prophylactic intervention is discouraged in the United Kingdom.The consequence is higher prevalence of preventable infections,adverse medical conditions,suffering and net costs to the UK’s National Health Service for treatment of these.Many of the issues and contradictions in the BMA guidance identified by Lempert et al stem from the BMA’s guidance not being sufficiently evidence-based.Indeed,that document called for a review by others of the medical issues surrounding NTMC.While societal factors apply,ultimately,NTMC can only be justified rationally on scientific,evidence-based grounds.Parents are entitled to an accurate presentation of the medical evidence so that they can make an informed decision.Their decision either for or against NTMC should then be respected. 展开更多

Introduction: Hypogonadism should be suspected in a man who has symptoms and signs of testosterone deficiency. Clinical manifestations depend on the severity and duration of testosterone deficiency, whether the testicular deficit is concerning only androgen synthesis, spermatogenesis, or both. The objective of our study was to evaluate the clinical and aetiological characteristics of male hypogonadism in Dakar’s suburb. Patients and methods: We conducted a transversal study from January 1<sup>st</sup>, 2020 to July 31<sup>st</sup>, 2022. We included all male patients aged at least 14 years old with hypogonadism confirmed by a low level of early-morning free testosterone based on two different dosages. For all patients included, sociodemographic and diagnostic parameters were collected by using a pre-established registration form. Results: In total, 20 patients were selected. The average age was 36.3 years old [14 - 62 years old]. Half of the patients were overweight. Five patients had an abdominal circumference greater than 94 cm (37 inches). The other comorbidities found in our patients were type 2 diabetes (n = 1), hypertension (n = 1) and primary hypercholesterolemia in 2 patients. The functional signs reported by the patients were: couple’s infertility in 17 patients, decreased libido in 14 patients, erectile dysfunction in 13 patients, premature ejaculation in 2 patients and anejaculation in 4 patients. The physical examination revealed a bilateral testicular atrophy in 17 patients and a unilateral testicular atrophy in 2 patients;no patient had varicocele or urethral meatus abnormalities. Ten patients presented a micropenis. A eunuchoid morphotype was present in 6 patients and a short stature was noted in 2 patients. It was peripheral hypogonadism (HH) in 18 patients and hypogonadotropic hypogonadism (Hh) in 2 patients. The hypogonadotropic hypogonadism was isolated in both cases. The testicular echography confirmed testicular atrophy and showed cryptorchidism in 5 patients. The pituitary MRI performed in 2 patients with Hh showed an aspect of empty sella turcica in one patient and was normal in the second patient. Conclusion: In our practice, the diagnosis of male hypogonadism is most often made in adulthood. The most usual clinical presentation is failure of pubertal sexual development associated or not with a eunuchoid morphotype. The anomalies of spermatogenesis are found in most patients. Infertility is the primary motive for consultation. 展开更多

Background: Male involvement during pregnancy and childbirth is very important as it has been shown to increase the number of times a pregnant woman undertakes antenatal care visits before delivery. The purpose of this study was to determine whether there is a relationship between the background characteristics of participants and their male partners’ involvement in maternal health care in the Bolgatanga Municipality of Upper East Region. Methods: The study design employed was a facility-based cross-sectional study design in 9 health facilities in the Bolgatanga municipality. The study populations for this study consisted of pregnant women using antenatal services in the health facilities before the commencement of this current study and are residents of the Bolgatanga municipality. A multistage sampling strategy was used in the sampling of participants for this study with an estimated sample size of 422. Results: Findings show that the majority of 403 (95.5%) of the participants expect their male partner accompanies them during the antenatal care clinic. The chi-square test revealed that marital status had a significant influence on male partners’ support in house chore and support in antenatal care service (P-value of 0.001 and 0.002, Conclusion: This study’s findings showed that pregnant women always want their male partners to accompany them to antenatal care and during labour and delivery. The pregnant women expected their male partners to be educated on the effects of pregnancy, how to take care of a pregnant woman, how to tolerate their partners, Sex during pregnancy, and how to prepare for emergencies (blood donation, transportation and finance). 展开更多

Objective: Exploring the therapeutic effects of acupuncture for male immune infertility using Meta-analysis. Methods: The literature related to clinical randomized controlled trials (RCTs) on acupuncture for male immune infertility published from the establishment of the database (journal) to 2021 was searched for RR values or OR values and 95% CI as effect indicators. RevMan 5.3 software was applied for meta-analysis. Results: Acupuncture or combination of acupuncture and herbal medicine (hereafter referred to as acupuncture and medicine) or electro-acupuncture, the total effective rate was significantly better than the control group, and the difference was statistically significant [RR = 1.29, 95% CI (1.20, 1.38), p 0.00001];In addition, the efficiency of the combined acupuncture and medicine treatment was better than that of the herbal medicine group alone, and the difference was statistically significant [RR = 1.05, 95%, CI (0.94, 1.16), P = 0.42];The sperm viability in the combined acupuncture and medicine treatment group was significantly better than that in the herbal medicine treatment group alone, and the differences were all statistically significant [MD = 0.04, 95% CI (?0.20, 0.28), P0.74];Sperm forward motion was significantly better in the combination of acupuncture and medicine than in the herbal medicine alone group, and the differences were all statistically significant [MD = 0.66, 95% CI (?0.04, 1.36), P = 0.06];ACP indexes were significantly higher in the combination of acupuncture and medicine than in the herbal medicine alone group, with a statistically significant difference [MD = 20.47, 95% CI (?65.31, 106.25), P = 0.64];The AsAb content in the seminal plasma of either needle medicine or acupuncture was lower than in the homogeneous prednisone group, and the difference was statistically significant [MD = ?7.00, 95% CI (?11.19, ?2.81), P = 0.001];The index of AsAb content in the serum of either needle medicine or acupuncture was lower than that of prednisone group, and the difference was statistically significant [MD = ?5.00, 95% CI (?9.53, ?0.47), P = 0.03]. Conclusion: Based on current evidence, acupuncture is more effective than Western medicine (prednisone) alone in the treatment of male immune infertility, and is more effective when combined with Chinese medicine. 展开更多
