Effect of methanol extract of Ricinus communis seed on reproduction of male rats

Aim： To investigate the effect of methanol extract of Ricinus communis seed （RCE） on male rats reproductive functions. Methods： Thirty-two male albino rats were divided into four groups. Groups 1, 2 and 3 were gavaged with 0.2 mL of 2.5% tween 80 （RCE vehicle; control） or 20 mg/（kg-d） and 40 mg/（kg-d） of RCE, respectively, for 30 days, and group 4 was also gavaged with 40 mg/（kg.d） of RCE, but was allowed a recovery periold of 30 days. Five untreated female rats were cohabited with male rats in each group from day 25 of RCE treatment for 5 days, except group 4, where cohabitation began on day 25 of the recovery period. All male rats were sacrificed 24 h after the experiments. The female rats were laparatomized on day 19 of pregnancy and the number and weight of litters were recorded. Results： There was a significant decrease （P 〈 0.01） in the weight of the reproductive organs, sperm functions and serum levels of testosterone in RCE treated rats. There was disorganization in the cytoarchitecture of the testes, disruption of the seminiferous tubules and erosion of the germinal epithelium. The number and weight of litters of rats in groups 2 and 4 decreased significantly （P 〈 0.05） but no changes were observed in group 3. RCE caused no changes in liver, kidney, heart or body weights in male rats. Conclusion： RCE has a reversible negative impact on male reproductive functions, which appears to be mediated via gonadal disruption in testosterone secretion. （Asian J Androl 2006 Jan; 8： 115-121）

Underground water affects sexual behavior and gene expression of hormones related to reproduction in blue gourami males

This study examined the effect of underground water on reproduction- and growth-related hormones in blue gourami males under non-reproductive and reproductive conditions. An increase in the percentage of males building nests under the highest percentage of underground water were compared to fish that maintained a lower percentage of underground water in the first two days. The % Gonado-somatic index (GSI) of males building nests was higher than non- reproductively active males in water containing the lowest concentration of underground water. In non- reproductively active males, brain gonadotropin releasing hormone 1 (GnRH1) and pituitary β subunit of gonadotropins (GtHs) and prolactin (PRL) mRNA levels were significantly higher in males maintained in underground water. In reproductively active males, mRNA levels of brain GnRH1, gonadotropin releasing hormone 3 (GnRH3) and pituitary PRL mRNA levels were significantly higher than males maintained in underground water. Thus, it is suggested that underground water with high salinity and conductivity levels affects the gene expression of repro- duction-related hormones;in reproductively active males, it shortened the duration of nest-building by blue gourami males.

Expression of Attractin in Male Reproductive Tract of Human and Mice and Its Correlation with Male Reproduction

The expression of Attractin mRNA and protein in testis and semen of human and male mice was investigated. Human testis and semen samples were all collected from Reproductive Center of Reumin Hospital, Wuhan University in December, 2012. Testis samples were collected from 7 cases of obstructive azoospermias when they were subjected to diagnosed testis biopsy, and 30 nor- mal human semen samples were obtained from those cases of semen analysis. Adult mice testis tis- sues were obtained from 10 2-month-old male BALB/c mice, and 60 male mice at different ages were classified into 10 groups （day 1, 5, 10, 15, 21, 28, 35, 42, 56, and 120 respectively, n=6 each）. The expression of Attractin mRNA and protein in testis was detected by RT-PCR and Western blotting re- spectively. Human semen samples were centrifuged into sperm plasma （SP） and sperm extract （SE）, and mice sperm samples were collected from the epididymis of 10 adult male BALB/c mice. Western blotting was used to determine the Attractin protein expression level. Attractin mRNA and protein were expressed in the testis of both patients with obstructive azoospermias and adult Bcl/B mice. Quantitative RT-PCR revealed that no Attractin mRNA was detectable in day 1 male BALB/c mice group. The Attractin mRNA and protein levels were low on the day 10, and increased with age until day 56. On the day 120, the expression levels of Attractin were decreased. As for human semen sam- pies, Attractin protein was expressed in both SP and SE, but didn＇t exist in samples from the epidi- dymis of male BALB/c mice. It was suggested that Attractin acted as a novel active substance and was involved in male reproduction in both human and BALB/c mice, but it exerted a different ex- pression profile in different mammal species.

Hormones in male reproduction and fertility

Male factor infertility accounts for about half of overall global infertility cases(1)It involves complex pathophysiological mechanisms(2)Since male reproductive functions are fine-tuned by orchestrated regulation of reproductive hormones, better understanding of male hormonal imbalance and the influence of their crosstalk with metabolic hormones, neuropeptides, and stress markers,etc. will potentiate further research in this direction.

Joint action of phoxim and fenvalerate on reproduction in male rats

Aim: To evaluate the joint action of phoxim and fenvalerate on the reproductive function in male Sprague-Dawley rats. Methods: The 2×2 factorial analysis experiment was used in the study. The pesticides were orally given at daily doses of phoxim (Pho) 8.2 nig/kg, fenvalerate (Fen) 3.3 mg/kg and Pho 8.2+Fen 3,3 mg/kg (Pho:Fen = 5:2), 5 days a week for 60 days. Sperm motility was measured with computer-assisted sperm motility analysis (CASA) and daily sperm production estimated. Immunoenzymatic method and electron microscopy were used to evaluate the serum testosterone and the testicular morphology, respectively. Results: There were significant decreases in sperm motility parameters in the treated animals, including straight line velocity (VSL), beat cross frequency (BCF), linearity (LIN) and straightness (STR). After treated with Fen, significant decreases in VSL, LIN and STR were demonstrated. Significant decreases of daily sperm production were seen in animals treated with Pho and Pho+Fen in comparison with the controls. Serum testosterone levels were not significantly changed in the treated groups. Factorial ANOVA showed that no significant interactions were noted between Pho and Fen in sperm motility, sperm production and serum testosterone. Both the single and mixed pesticides caused various degrees of testicular lesions, involving vacuolation of endoplasmic reticulum and necrosis of Sertoli cells. Conclusion: The pesticides may cause sperm motility changes and testicular lesions in male rats. The action of Pho and Fen may be additive.

Obestatin in male reproduction and infertility

Obestatin is a 23-amino acid peptide hormone secreted by the stomach and is found in several tissues all over the body, such as the gastric mucosa, spleen, mammary gland, plasma as well as in the testicular Leydig cells. Obestatin seems to operate as part of the integrated gut-brain network acting as an anorectic hormone, reducing food intake and reversing body weight gain. Besides the expressions of obestatin in male reproductive tissues, it is also shown to increase testosterone secretions, thus ameliorating testicular functions. In the present scenario where the increasing prevalence in obesity is considered as one of the major causatives of worldwide declining trend of semen quality, molecules like obestatin playing roles in both metabolic and reproductive functions find importance in management of obesity-induced male infertility or subfertility. The present review article aims to provide updated concepts on obestatin and its mode of actions, and its role in modulation of male reproductive functions.

Adiponectin in male reproduction and infertility

Adiponectin is an adipokine that has the highest plasma concentration among all other adipokines. It is a white adipose tissue secretion essential for the regulation of energy metabolism owing to its antiatherogenic insulin-resistance, and anti-inflammatory properties. Studies have put forth that adiponectin is a potent endocrine regulator with mechanisms relating energy balance with reproductive function in different species, including humans. The two adiponectin receptors, AdipoR1 and AdipoR2 have been found to be expressed in the prime regulatory axis of reproduction, the hypothalamic-pituitary-gonadal axis. The activation of adiponectin receptors has been shown to regulate the secretion and gene expressions of kisspeptin, gonadotropin-releasing hormone and gonadotropins. Adiponectin finds relevance in the regulations of most of the vital testicular functions, such as steroidogenesis, germ cell proliferation and their coordinated apoptosis, as well as in modulation of testicular redox status and oxidative stress. Since metabolic syndrome and their associations with male infertility have been gaining immense research interest, adiponectin seems to be one of the important mediators of metabolic syndrome-induced male reproductive dysfunctions. This article aims to review the patterns of adiponectin expression in the male reproductive tissues and the mechanism by which adiponectin modulates male reproductive functions.

Ghrelin and male reproduction

Ghrelin is a multifunctional peptide hormone, conventionally known to be secreted by the stomach. The synthesis of ghrelin by the reproductive organs signifies its autocrine and/or paracrine actions upon the gonads. Expression of the functional ghrelin receptor is observed in different levels of the hypothalamic-pituitary-gonadal axis, suggesting its action on hypothalamic secretion of gonadotropin-releasing hormone and the pulsatile secretion of pituitary gonadotropins. It mainly acts to inhibit the secretion of the luteinizing hormone and thereby may also hinder proper testicular functions. This review article aims to provide a concise concept on (a) the characteristics, secretion and mode of actions of ghrelin, and (b) the role of ghrelin as a potential regulator of male reproductive functions. It may act upon the hypothalamic-pituitary-gonadal axis as well as directly regulate key testicular functions such as testosterone secretion, Leydig cell proliferation and expressions of prime functional proteins in the seminiferous tubule. These actions of ghrelin on testicular functions appear to be species-specific. Ghrelin and its versatile biological functions bring to a consensus that further research on ghrelin may establish one of the associations between body energy status with alterations in male reproductive functions.

Role of melatonin in male reproduction

Melatonin, conventionally accepted as a pineal gland secretion, is a neuromodulator whose physiological concentrations are regulated by circadian rhythms. Alteration in melatonin levels owing to circadian influences is a major regulator of reproductive functions in animal species that are seasonal breeders. Attributing to its antioxidant properties and capability to cross physiological barriers, such as the blood-brain barrier, the blood-testis barrier as well as having almost no toxicity, melatonin finds high relevance in amelioration of male fertility parameters. Melatonin may affect male reproductive functions by influencing the release of hypothalamic gonadotropin-releasing hormone and pituitary luteinizing hormone, which are among the key hormones in regulation of male reproduction. It may directly act on testicular cells to influence testicular functions. The property of melatonin most essential for testicular functions is its ability to scavenge free radicals, thereby preventing testicular oxidative damage. This article summarizes the updated data on the versatility of melatonin as an endogenous rhythm setter, as an antioxidant molecule and its possible physiological impacts in male reproductive functions.

Effects of Cow’s Milk on Reproduction in ICR Male Mice

Objective To study the effects of Cow＇s milk on the reproduction in male mice. Methods Twenty-four male mice were divided randomly into two groups： milk group （M） and control group （C）. Each mouse was given 10 mL milk per day from 4 to 16 weeks in the group M. At the age of 17 weeks, all the mice were sacrificed. Results Serum testosterone was decreased in the group M （P=0.037）. No significant difference was found in weight of testes, seminal vesicle or adrenal gland of mice between the groups C and M. However, the weight of seminal vesicle decreased when expressed in g/100 g body weight in the group M. Epididymal sperm concentration, motility, morphology, and sperm head number were not affected by milk. Conclusion Cow＇s milk has adverse effects on the reproductive system in ICR male mice. Further studies are needed to clarify the specific effects of milk on reproductive health.

The life-history trait trade-offs mediated by reproduction and immunity in the brown planthopper,Nilaparvata lugens Stål

Reproduction and immune defense are costly functions,and they are expected to tradeoff with each other to drive evolution.The brown planthopper(BPH),Nilaparvata lugens Stål(Hemiptera,Delphacidae),is a global superpest that mostly damages rice crops.Yeast-like symbionts(YLS)exist in the abdominal fat body tissue and are tightly associated with the development,growth,and reproduction of BPH.Our previous research demonstrated that mating behavior promotes the release of YLS from the fat body into the hemolymph in the BPH,thereby triggering an immune response.Additionally,the fitness costs related to life-history traits of BPH(such as survival rate)have a strong dependence on the relative abundance of YLS.However,the possible relationship between reproduction and the immune response in BPH has not been identified.In this study,an omics-based approach was used to analyze the transcriptome of fat body tissues in mated and unmated BPH at 72 h post-eclosion,from which two antimicrobial peptide genes,NlDefensin A(NlDfA)and NlDefensin B(NlDfB),were selected since they were highly expressed in mated BPH.Subsequently,the full-length cDNA sequences of the NlDfA and NlDfB genes were cloned and analyzed.qPCR results showed up-regulation of the NlDfA and NlDfB genes in mated BPH when compared to unmated BPH.Spatial-temporal expression analysis indicated that the NlDfA and NlDfB genes were expressed in all tissues and developmental stages,and they were most highly expressed in the fat body at 24 h post-eclosion.Moreover,the symbionts in BPH were significantly inhibited by the in vitro expression of the NlDfA and NlDfB proteins.Furthermore,RNA interference(RNAi)-mediated suppression of NlDfA and NlDfB dramatically increased the relative abundance of YLS in the fat body,while YLS in the hemolymph decreased significantly.These BPHs also displayed some fitness disadvantages in survival,fecundity,hatchability,and possibly the vertical transmission of YLS from hemolymph to egg.Our results indicated that mating could heighten the immunity of BPH by upregulating the expression of the NlDfA and NlDfB genes,which protect the host from pathogen challenges during reproduction.However,the reduced content of YLS may act as a fitness disadvantage in dictating the life-history traits of BPH.This work has significant theoretical and practical implications for the precise green control technology that involves crucial gene targeting,as well as for the“endosymbionts for pest control”strategy in insects.

Tissue distribution of cadmium and its effect on reproduction in Spodoptera exigua

Vegetable fields are often contaminated by heavy metals,and Spodoptera exigua is a major vegetable pest which is stressed by heavy metals mainly by feeding.In this study,cadmium accumulation in the tissues of S.exigua exposed to cadmium and its effects on the growth and development of the parents and the offspring were investigated.Under the stress of different concentrations of cadmium(0.2,3.2,and 51.2 mg kg^(-1)),the cadmium content in each tissue of S.exigua increased in a dose-dependent manner.At the larval stage,the highest cadmium accumulation was found in midgut in all three cadmium treatments,but at the adult stage,the highest cadmium content was found in fat body.In addition,the cadmium content in ovaries was much higher than in testes.When F1S.exigua was stressed by cadmium and the F_(2)generation was not fed a cadmium-containing diet,the larval survival,pupation rate,emergence rate and fecundity of the F_(2)generation were significantly reduced in the 51.2 mg kg^(-1)treatment compared to the corresponding F1generation.Even in the F_(2)generation of the 3.2 mg kg^(-1)treatment,the fecundity was significantly lower than in the parental generation.The fecundity of the only-female stressed treatment was significantly lower than that of the only-male stressed treatment at the 3.2 and 51.2 mg kg^(-1)cadmium exposure levels.When only mothers were stressed at the larval stage,the fecundity of the F_(2)generation was significantly lower than that of the F1generation in the 51.2 mg kg^(-1)treatment,and it was also significantly lower than in the 3.2 and 0.2 mg kg^(-1)treatments.The results of our study can provide useful information for forecasting the population increase trends under different heavy metal stress conditions and for the reliable environmental risk assessment of heavy metal pollution.

Advances in DNA methylation and its role in cytoplasmic male sterility in higher plants

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.

A study on the cognitive status of human papillomavirus among adult males in Tianjin based on the health belief model

Background:To understand the health beliefs and knowledge of human papillomavirus among adult males in Tianjin.Methods:An online questionnaire survey was conducted from 18 January 2023 to 6 March 2023 using snowball sampling method.Analyze the health belief scores and human papillomavirus(HPV)and HPV vaccine knowledge scores of adult males in Tianjin,and analyze their influencing factors.Results:A total of 388 adult males in Tianjin were surveyed,with an average total score of 3.23±0.04 for their health beliefs.Among them,the average scores for perceived severity,perceived susceptibility,perceived impairment,perceived benefit,and self-efficacy were 3.41±1.05,2.37±1.20,2.96±1.00,3.51±0.90,and 3.36±1.08,respectively.Multiple linear regression analyses showed education was a factor influencing health beliefs.The average total score of knowledge is 64.09±15.62,with 277 people scoring above 60,and a pass rate of 71.4%.Through multiple linear regression analysis,education level,emotional status,whether disease testing has been done,and whether family and friends have been diagnosed with HPV positive are the main influencing factors.Conclusion:The awareness rate of HPV among adult males in Tianjin is still acceptable,but there are still misconceptions.The overall level of health beliefs is moderate,and the perceived susceptibility level is low.It is necessary to strengthen health education on HPV related knowledge for males and improve their cognitive level.

Exploring the relationship between Hashimoto's thyroiditis and male fertility:A meta-analytic and meta-regression perspective on hormonal and seminal factors

Objective:To explore the relationship between Hashimoto's autoimmune hypothyroidism(HT)and male fertility,focusing on hormonal and seminal factors.Methods:A systematic literature search was conducted across databases such as PubMed,Web of Science,EMBASE,Scopus,Cochrane,and Google Scholar,covering studies published from January 2000 to March 2024.Studies investigating the impact of HT on semen quality parameters and reproductive hormones were included.Pooled effect estimates were calculated using standard mean difference(SMD)and 95%confidence intervals(CI).Results:A total of 8 studies with 8965 participants were included.HT significantly affected semen quality and reproductive hormone levels.Specifically,there was a notable decrease in progressive morphology(SMD=-0.78;95%CI:-1.40 to-0.17;P=0.01)and sperm motility(SMD=-1.151;95%CI:-1.876 to-0.425;P=0.002).In addition,there were no significant changes in reproductive hormones,although there were elevated levels of luteinizing hormone(SMD=0.437;95%CI:0.000 to 0.874;P=0.050)and follicle-stimulating hormone(SMD=0.293;95%CI:-0.171 to 0.758;P=0.216),with a slight impact on testosterone levels(SMD=-1.143;95%CI:-2.487 to 0.200;P=0.095).Conclusions:This systematic review and meta-analysis provides robust evidence of the detrimental effects of HT on semen quality and reproductive hormones,underscoring the necessity for thorough evaluation and management of thyroid function in male infertility assessments.

Epidemiological and Clinical Aspects of Male Infertility in Patients Consulting at the Urology Department of the Yaounde Central Hospital

Introduction: About 10 to 15% of couples in the world and 20 to 30% in Cameroon consult for infertility problems. 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 1st, 2016 to April 30th, 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.

Long Term Administration of Lannea acida Rich. (Anacardiaceae) Reverses the Imidacloprid-Induced Fertility Impairments in Adult Male Rat through Androgenic and Antioxidant Properties

Aim: The harmful effects of pesticides have been largely documented in recent times. 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.

Spermotrend Improves Semen Quality and Infertility in Men with Varicocele —Spermotrend and Male Infertility

Background: Infertility affects 8% - 12% of couples globally, with approximately half of the cases reported in males. Oxidative stress is a common factor increased in the varicocele condition and particularly affects spermatozoa, due to their sensitivity to oxidative signals and testicular hypotrophy. The objective of this clinical trial is to study the effectiveness of Spermotrend in the improvement of sperm parameters in male infertility. Methods: A total of 170 males aged > 18 years with a diagnosis of infertility and varicocele were consecutively enrolled in a Phase II, open-label clinical trial. Spermotrend was administered 1 capsule (450 mg) orally every 8 hours for 6 months and was evaluated through semen analysis at 4 and 6 months of follow-up. Results: The trial results show a significant improvement following the administration of Spermotrend over 6 months in sperm concentration (44.1% at baseline vs. 64.1% at 6 months), sperm survival (28.2% with sperm survival ≥ 2 hours vs.56.5%), normalization of sperm morphology (31.2% vs. 72.9%). Varicocele condition decreased in all patients and, by the end of the study, 55.3% of patients had normal venous flow and dilation. Only 5.9% of the patients showed grade 2 varicocele at the end of the study, while 38.8% showed grade 1 varicocele, with no patients showing grade 3 varicocele. Regarding testicular hypotrophy, 90.6% of the patients completed the study with normalized testicular volume by recovering normal venous flow. Conclusion: A short-term course of Spermotrend may significantly improve sperm parameters associated with male infertility. Clinical Trial Registration: The clinical trial protocol was registered in the international clinical trial registry, ClinicalTrials.gov, with the code: NCT05222841 on 15/06/2021.

Granulomatous mastitis in a 50-year-old male:A case report and review of literature

BACKGROUND Granulomatous mastitis(GM)an inflammatory disease of the breast that usually affects women of childbearing age,occurs very rarely in males.CASE SUMMARY We present a case study of a 50-year-old male patient with GM.The patient developed a breast lump following the cleaning of a previously embedded dirtfilled nipple.While an initial improvement was noted with antibiotic therapy,a recurrence occurred a year later,showing resistance to the previously effective antibiotics.Subsequently,the lesion was excised.The histopathological examination confirmed the diagnosis of GM.CONCLUSION GM should be considered a possible diagnosis of male breast masses.

Pro-fertility effect of Ficus carica fruit extract in streptozotocin-induced male rats

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.
