RESUMO

BACKGROUND: Abnormal female immune response is one of the potential causes of unexplained infertility (UI). Seminal plasma (SP) is an important regulator of female immune responses during pregnancy. This study investigated a SP effect on the expression of CD4+ T-cell-related cytokines in a group of UI woman candidates for in vitro fertilization (IVF) and healthy fertile women. MATERIALS AND METHODS: This was a semi-experimental study that performed on 20 UI couples (ten unsuccessful and ten successful IVF outcomes) and 10 fertile couples as the healthy group. CD4+ T-cells were separated from peripheral blood mononuclear cells of women by magnetic-activated cell sorting technique and incubated with (stimulated condition) or without (unstimulated condition) SP of their husbands. After incubation, real-time polymerase chain reaction method was used to investigate interleukin (IL)-23, IL-17, IL-4, IL-10, transforming growth factor (TGF)-ß, and interferon (IFN)-γ gene expression. Mann-Whitney U-test, Kruskal-Wallis test, and Wilcoxon signed-rank test were used for statistical analysis. RESULTS: Baseline TCD4+ mRNA levels of IL-23 (P = 0.03) and TGF-ß (P = 0.01) were different between healthy and infertile groups. However, IL-17, IL-4, IFN-γ, and IL-10 were expressed similarly regardless of fertility status. Comparing mRNA expression before and after SP exposure, our results have shown that relative expression of IL-23 significantly increased in successful (P = 0.04) and unsuccessful IVF groups (P = 0.01), whereas IL-10 expression increased only in the IVF failure group (P = 0.01). CONCLUSION: SP can make a positive effect on IVF outcome through alteration in CD4 + T-cell-related cytokines expression, especially IL-10 and IL-23.

RESUMO

BACKGROUND: Recurrent pregnancy loss (RPL) defined as three or more consecutive spontaneous miscarriages before the 20th week of gestation is caused by different factors including genetic and epigenetic background. However the involvement of paternal background on RPL is an interesting novel argument, which is not well studied. The main focus of the present study was to investigate for the association of paternal methylenetetrahydrofolate reductase (MTHFR) epigenotypes with sperm parameters and RPL. Moreover, the frequency of two of MTHFR Single Nucleotide Polymorphisms (SNPs) in males was assessed. METHODS: This is a case-control study. Methylation Specific PCR (MSP) was used to evaluate the methylation status of MTHFR promoter on sperm DNA of 25 male partners of RPL and 25 male partners of non-RPL couples. PCR-RFLP method was used to analyze 1,298 A>C (rs1801131) and 677 C>T (rs1801133) polymorphisms. RESULTS: No significant difference was observed in frequency of methylated MTHFR epigenotype between RPL and non-RPL males. Furthermore, methylated MTHFR epigenotype was more frequent (but not statistically significant) among men with abnormal sperm parameters compared to normal-sperm men. Among studied polymorphisms, only the mutated allele of C677T showed statistically higher prevalence among RPL males. CONCLUSIONS: Although our results do not establish any connection between MTHFR epigenotypes and RPL they do highlight the impact of C677T in the pathology.

RESUMO

Our aim is to assess the effect of cinnamon powder capsules on insulin resistance, anthropometric measurements, glucose and lipid profiles, and androgens of women with polycystic ovarian syndrome (PCOS). Out of 80 women that were diagnosed as PCOS by Rotterdam Criteria, 66 were enrolled in this randomized double-blind placebo-controlled clinical trial. All of the PCOS women were taking medroxy progesterone acetate 10 mg/day for the last 10 days of their menstrual cycles. The cases were randomly allocated to 2 groups. The women in the first group were treated by cinnamon powder capsules 1.5 g/day in 3 divided doses for 12 weeks and the second group by similar placebo capsules. Anthropometric measurements, fasting blood sugar, fasting insulin, blood glucose 2 hr after taking 75 g oral glucose, HbA1c, testosterone, dehydroepiandrosterone sulphate, homeostatic model assessment for insulin resistance, triglyceride, and cholesterol (low-density lipoprotein, high-density lipoprotein, and total) before and after the intervention were evaluated and compared as outcome measures. Fasting insulin (p = .024) and homeostatic model assessment for insulin resistance (p = .014) were reduced after 12 weeks in the cinnamon group compared with the placebo. There was also a significant decrease in low-density lipoprotein in cinnamon group (p = .004) as compared with baseline that caused significant difference with placebo (p = .049). However, changes in other outcome measurements did not lead to statistically significant difference with placebo. The present results suggest that complementary supplementation of cinnamon significantly reduced fasting insulin and insulin resistance in women with PCOS.

RESUMO

BACKGROUND: Despite the large number of papers published on the efficiency of different exogenous gonadotropins, no confirmed protocol exists. Therefore, the aim of the present study was to compare the efficacy of 4 exogenous gonadotropins in IVF/ICSI cycles. METHODS: This study, performed from January 2014 to May 2014, recruited 160 women referred to Ghadir Mother and Child Hospital and Dena Hospital, Shiraz, Iran. The patients underwent standard downregulation and were randomly divided into 4 groups of A, B, C, and D and were administered hMG, hFSH, rFSH, and combined sequential hFSH/rFSH, respectively. Then, the duration of stimulation, number of oocytes and embryos as well as their quality, implantation rate, biochemical and clinical pregnancy rate, and live birth rate in each group were evaluated. RESULTS: Group D patients required significantly fewer ampoules of FSH than did the women in groups A, B, and C (P=0.004). The duration of stimulation was significantly longer in group C than in groups A and D (P=0.030). The serum estradiol level was significantly higher in group D than in groups B and C (P=0.005). A significantly higher number of large-sized follicles was observed in group D than in group B (P=0.036). CONCLUSION: Our data revealed no statistically significant differences in the mean oocyte number, embryo quality, clinical pregnancy rate, or live birth rate between the hMG, hFSH, rFSH, and sequential hFSH/rFSH protocols. However, several differences in the duration of stimulation, serum estradiol levels, and number of large-sized follicles were detected between the groups. Trial Registration Number: IRCT201408116541N7.

RESUMO

Diminished ovarian reserve (DOR) significantly decreases the success rate of the assisted reproductive technique (ART). In this study, we assessed the effect of melatonin on the ART outcomes in women with DOR. A double-blinded, randomized, clinical trial was performed on 80 women with DOR as a pilot study in Shiraz, between 2014 and 2015. DOR was defined as the presence of 2 of the following 3 criteria: 1) anti-Müllerian hormone ≤1, 2) follicle-stimulating hormone ≥10, and 3) bilateral antral follicle count ≤6. The women received 3 mg/d melatonin or a placebo since the fifth day of one cycle prior to gonadotropin stimulation and continued the treatment up to the time of ovum pickup. The ART outcomes were compared between the groups using SPSS software. Finally, there were 32 women in the case and 34 in the placebo groups. The mean age and basal ovarian reserve test were the same between the groups. The serum estradiol level on the triggering day was significantly higher in the case group (P=0.005). The mean number of MII oocytes was higher in the case group, but the difference did not reach statistical significance. Number of the patients who had mature MII oocytes (P=0.014), top-quality embryos with grade 1 (P=0.049), and embryos with grades 1 and 2 (P=0.014) was higher among the women who received melatonin. However, the other ART outcomes were not different between the groups. The serum estradiol level was higher and more women with DOR had good-quality oocytes and embryos after receiving melatonin; however, no other outcome was different between the case and control groups. Trial Registration Number: IRCT2014041417264N1.

RESUMO

BACKGROUND: We sought to compare the effectiveness and safety of sublingual versus vaginal misoprostol for the termination of pregnancy with a live full-term fetus. METHODS: This randomized, triple-blind, placebo-controlled clinical trial was performed on 200 primiparous women with normal, singleton, full-term pregnancies candidated for the induction of labor. Sublingual and vaginal tablets containing misoprostol (25 mcg) or placebo in similar shapes were administered every 4 hours until the Bishop score reached above 8. Maternal and neonatal complications and outcomes were compared. RESULTS: There were 100 parturient women in each group. The mean maternal age, gestational age, and Bishop score at the commencement of misoprostol had no statistical differences between the sublingual and vaginal groups. The mean time interval between misoprostol commencement and delivery was 497.10±291.49 and 511.67±08.46 minutes for the sublingual and vaginal groups, correspondingly. Twenty-two women had Cesarean deliveries in the sublingual group versus 14 in the vaginal group. Meconium-stained amniotic fluid was seen in 12 women in the sublingual group and 4 in the vaginal group (P=0.03). Late fetal heart rate deceleration was observed in 8 women in the sublingual group and 4 in the vaginal group (P=0.22). The mean neonatal birth weight, blood gas value at birth, Apgar score, and length of admission time in the neonatal intensive care unit were not different between the 2 groups. CONCLUSION: Sublingual and vaginal misoprostol had similar effectiveness; however, meconium-stained liquor was observed considerably more frequently with sublingual misoprostol than with vaginal misoprostol. TRIAL REGISTRATION NUMBER: IRCT201402096541N3.

RESUMO

Polycystic ovary syndrome (PCOS) is the most common endocrine-related reproductive disorder in women of reproductive age, accompanied by both the impairment of female fecundity and a risk of metabolic disorders. PCOS is emphasized as a worldwide concern due to its unknown etiology and lack of specific medications. The current study aimed to evaluate the effects of L-tartaric acid, an abundantly occurring compound in fruits, on the histostereological and hormonal changes caused by PCOS. Forty adult Sprague Dawley rats were randomly divided into four groups including controls (no intervention), Tartaric acid (40mg/Kg/day from day 21 onwards for 39 days), PCOS (21 days letrozole and then normal saline orally for 39 days), and PCOS + Tartaric acid. After treatments, the ovarian histostereological analysis as well as the level of reproductive hormones including luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, progesterone, and testosterone was measured. PCOS caused a significant decrease in the number of unilaminar, multilaminar, antral, and graafian follicles and increased follicular atresia (p-value < 0.001). Moreover, the weight and volume of ovarian tissue and related structures including cortex, medulla, and cysts increased significantly (p-value < 0.0001). However, corpus luteum volume was significantly decreased (p-value < 0.001). Although significant differences were found in some parameters with the control group (p-value < 0.05), the administration of tartaric acid restored the pathological effects of PCOS on the ovarian histostructure. Furthermore, tartaric acid improved the serum levels of LH, estradiol, progesterone, and testosterone (p-value < 0.05). The obtained findings may suggest tartaric acid as a novel strategy for PCOS management, although further studies are necessary.

RESUMO

BACKGROUND: Cervical cancer, a pernicious gynecological malignancy, causes the mortality of hundreds of thousands of females worldwide. Despite a considerable decline in mortality, the surging incidence rate among younger women has raised serious concerns. Immortality is the most important characteristic of tumor cells, hence the carcinogenesis of cervical cancer cells pivotally requires compromising with cell death mechanisms. METHODS: The current study comprehensively reviewed the mechanisms of non-apoptotic cell death programs to provide possible disease management strategies. RESULTS: Comprehensive evidence has stated that focusing on necroptosis, pyroptosis, and autophagy for disease management is associated with significant limitations such as insufficient understanding, contradictory functions, dependence on disease stage, and complexity of intracellular pathways. However, ferroptosis represents a predictable role in cervix carcinogenesis, and ferroptosis-related genes demonstrate a remarkable correlation with patient survival and clinical outcomes. CONCLUSION: Ferroptosis may be an appropriate option for disease management strategies from predicting prognosis to treatment.

RESUMO

This study investigated the effects of pentoxifylline (PTX), high intensity interval training (HIIT) and moderate intensity continuous training (MICT) separately and in combination, on inflammatory and apoptotic pathways in the rat model of induced endometriosis. Endometriosis was induced through surgery on female Sprague-Dawley rats. Six weeks after the first surgery, the second look laparotomy was performed. After induction of endometriosis in rats, they were divided into control, MICT, PTX, MICT+ PTX, HIIT, HIIT+PTX groups. Two weeks after the second look laparotomy, PTX and exercise training interventions were performed for eight weeks. Endometriosis lesions were assessed histologically. Proteins content of the NF-κB, PCNA and Bcl-2 were measured by immunoblotting and genes expression of the TNF-α and VEGF were measured by Real-time PCR methods. Findings of the study indicated that, PTX significantly decreased volume and histological grading of lesions, proteins of NF-κB and Bcl-2; and genes expression of the TNF-α, and VEGF in lesions. HIIT significantly decreased volume and histological grading of lesions, NF-κB, TNF-α and VEGF in lesions. MICT did not induce any significant effect on the study variables. Although, MICT+PTX decreased significantly volume and histological grading of lesions, as well as NF-κB, and Bcl-2 in lesions, however, these factors were not significantly different with the PTX group. HIIT+PTX decreased significantly all of the study variables compared to other interventions, except for VEGF when compared to PTX. In summary, combination of PTX and HIIT can induce enhancing effect on suppression of endometriosis through suppressing inflammation, angiogenesis, and proliferation and enhancing apoptosis.

RESUMO

Non-obstructive azoospermia (NOA) is the most clinical problem in case of infertility. About 70% of NOA patients are idiopathic with uncharacterized molecular mechanisms. This study aimed to analyze the possible pathogenic miRNA-target gene interaction and lncRNA-miRNA association involved in NOA. In the current study, differentially expressed (DE) nRNAs, miRNAs and lncRNAs were determined using the microarray dataset and statistical software R. miRNAs-mRNA and miRNA-lncRNA interactions were identified and the base-pair binding between the seed region of miRNAs and complementary nucleotides in 3' UTR of mRNAs were analyzed. The influence of the validated single nucleotide polymorphisms (SNPs) was described by calculating the minimum free energy (MFE) of the interaction. A total of 74 mRNAs, 14 miRNAs, and 10 lncRNAs were identified to have significant differential expression in testicular tissue between patients and the fertile group. Four of the DE-mRNAs and all of the reported DE-miRNAs were upregulated. In addition, all of the represented DE-lncRNAs were showed to be downregulated. miR-509-5p and miR-27b-3p were found to interact with target gene polo-like kinase 1 (PLK1) and Cysteine-rich secretory protein2 (CRISP2), respectively. Rs550967205 (A > G) positioned at 3' UTR CRISP2 and rs544604911 (T > C) located at 3' UTR PLK1, with lowest MFE in miRNA-mRNA interaction, were assumed to have possible pathogenic roles linked to spermatogenesis arrest. The results of the study provide new clues to understand the regulatory roles of miRNAs and lncRNAs in the pathogenesis and diagnosis of idiopathic azoospermia. Communicated by Ramaswamy H. Sarma.

RESUMO

Objectives: Genital wart is a sexually transmitted disease caused by human papillomavirus (HPV) and is responsible for discomfort, and decreased quality of life and productivity in victims with a high recurrence rate after treatments. This study aimed to compare the efficacy and safety of formaldehyde 5% with cryotherapy for the treatment of female genital warts. Methods: Eighty women with at least two similar genital warts who visited the outpatient dermatology clinic of Shahid Faghihi hospital, Shiraz, Iran, were enrolled in this study. One lesion of each patient was self-treated with formaldehyde 5% in flexible collodion gel once daily for 28 days and the other matched lesion was treated by weekly repeated cryotherapy courses. The number of eradicated lesions and the mean days needed to treat, pain scores, complications and patient satisfaction were compared between the treatment methods. Results: Complete clearance of lesions was observed in 58.7% of formaldehyde-treated lesions compared to 88.7% for cryotherapy (P value = 0.000). With formaldehyde-treated lesions, 51% complained of pain, 36.3% had pruritus, 86.3% had skin dryness, 88.8% complained of burning sensation and 93.7% showed erythema. In the cryotherapy group, 92.5% complained of pain, 15% had burning sensation, 75% showed erythema, 5% had atrophy, 80% developed post-inflammatory hyper or hypopigmentation (PIH) and 92.5% suffered from ulceration. Seventy-five (93%) found it easy to apply and (47) 58% were satisfied with their treatment results. Conclusions: Self-administration of formaldehyde 5% resulted in a lower clearance rate but had better cosmetic outcomes with lower pain scores compared to cryotherapy.

RESUMO

OBJECTIVE: Male infertility secondary to exposure to gonadotoxic agents during reproductive age is a concerning issue. The aim of this experimental study was to determine the effect of Loboob on sperm parameters. METHODS: 55 healthy rats were selected, weighted and divided into five groups consisting of 11 rats each. The control group received no medication. Rats in Treatment Group 1 received 10mg/kg Busulfan and rats in Treatment Groups 2, 3, and 4 received 35,70 and 140 mg/kg Loboob respectively in addition to 10mg/kg Busulfan. Finally, the sperm parameters and weights of the rats were compared using the Kolmogorov-Smirnov, non-parametric Kruskal-Wallis, and Dunn-Bonferroni tests. RESULTS: All sperm parameters and weights were significantly decreased among rats receiving Busulfan. All dosages of Loboob were effective to enhance the motility of slow spermatozoa, while only in the rats given 70 and 140 mg/kg of Loboob saw improvements in progressively motile sperm percentages (0.024 and 0.01, respectively). Loboob at a dosage of 140mg/kg improved sperm viability. It did not improve normal morphology sperm or decrease immotile sperm counts. Loboob did not affect mean rat weight. CONCLUSIONS: Loboob offered a dose-dependent protective effect on several sperm parameters in rats with busulfan-induced subfertility.

RESUMO

BACKGROUND: Busulfan is an antineoplastic medication that is broadly utilized for cancer treatment. It affects the testicular function and leads to sterility. The present study aimed to evaluate the effects of ellagic acid on testicular tissue changes, sexual hormones, antioxidant defense system, and caspase-9 and Bcl2 gene expression in the busulfan-induced relative sterile rat model. METHODS: This is an interventional-experimental animal study that was performed on 65 Adult male rats; they were randomly divided into five groups including control (1 ml of 0.9% normal saline), ellagic acid (50 mg/kg); busulfan (10 mg/kg); and busulfan plus ellagic acid (10 mg/kg and 50 mg/kg). At the end of the experiment, blood samples were collected, and plasma levels of sex hormones, antioxidant system, apoptosis-related genes, and testis histology were assessed. RESULTS: Busulfan reduced the levels of serum testosterone, total antioxidant capacity, gene expression of Bcl2, testicular volume, seminiferous tubule, germinal epithelium, interstitial tissue volume, and the number of spermatogonia, spermatocyte, round spermatid, elongated spermatid, Sertoli cells and Leydig cells (p < 0.05). Busulfan administration resulted in a significant increase (p < 0.05) in the level of LH, FSH, malondialdehyde, and caspase 9. Busulfan + ellagic acid (50 mg/kg) showed higher serum levels of testosterone, gene expression of Bcl-2 and antioxidant markers, and lower LH, FSH levels, and gene expression of caspase 9 compared to the Busulfan-treated rats (p < 0.05). Stereological parameters were also ameliorated in the group treated with Busulfan+ 50 mg/kg ellagic acid (p < 0.05). CONCLUSION: In conclusion, the consumption of ellagic acid may have beneficial effects on the antioxidant defense system, sexual hormone abnormality, and testicular tissue damage induced by busulfan.

RESUMO

Coronavirus disease 2019 (COVID-19), a global pandemic, is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Angiotensin-converting enzyme 2 (ACE2) is the receptor for SARS-CoV-2 and transmembrane serine protease 2 (TMPRSS2) facilitates ACE2-mediated virus entry. Moreover, the expression of ACE2 in the testes of infertile men is higher than normal, which indicates that infertile men may be susceptible to be infected and SARS-CoV-2 may cause reproductive disorder through the pathway induced by ACE2 and TMPRSS2. Little is known about the pathway regulation of ACE2 and TMPRSS2 expression in male reproductive disorder. Since the regulation of gene expression is mediated by microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) at the post-transcriptional level, the aim of this study was to analyze the dysregulated miRNA-lncRNA interactions of ACE2 and TMPRSS2 in male reproductive disorder. Using bioinformatics analysis, we speculate that the predicted miRNAs including miR-125a-5p, miR-125b-5p, miR-574-5p, and miR-936 as regulators of ACE2 and miR-204-5p as a modulator of TMPRSS2 are associated with male infertility. The lncRNAs with a tissue-specific expression for testis including GRM7-AS3, ARHGAP26-AS1, BSN-AS1, KRBOX1-AS1, CACNA1C-IT3, AC012361.1, FGF14-IT1, AC012494.1, and GS1-24F4.2 were predicted. The identified miRNAs and lncRNAs are proposed as potential biomarkers to study the possible association between COVID-19 and male infertility. This study encourages further studies of miRNA-lncRNA interactions to explain the molecular mechanisms of male infertility in COVID-19 patients.

RESUMO

BACKGROUND: Male infertility is a main clinical problem that affects about 7% of all men worldwide. Many patients with male infertility are caused by a reduced antioxidant capacity of semen. Several antioxidant supplements, especially vitamin E, are proposed to help male infertility treatment. This project was goaled to study the effects of oral synthetic vitamin E (400 IU/day) for eight weeks on betterment of semen parameters and pregnancy rate. METHODS: After dropping the cases, 124 infertile couples with a male factor who were admitted to the IVF program were included. The male patients with idiopathic abnormal motility and/or morphology were randomized into two groups: 61 receiving vitamin E and 63 as the control group receiving placebo for eight weeks. The pretreatment semen parameters of both groups were compared with those of posttreatment. The pregnancy outcomes were considered between the two groups. RESULTS: There were no significant differences statistically between before and after treatment in the term of sperm volume, count, motility, and morphology. Furthermore, the IVF outcomes of the two groups were not different significantly, either. Interestingly, the percent of normal sperm in the placebo group was significantly decreased after eight weeks. CONCLUSION: Vitamin E supplementation might neutralize free radical activity to keep sperm from more oxidative damages. Further studies regarding the influence of higher acceptable doses of vitamin E on semen characteristics and fertility rates are needed. This study was registered as a two-arm, blinded, randomized, placebo-controlled clinical trial (IRCTID: IRCT2014020616506N1, 2014-03-18).

RESUMO

BACKGROUND: Insulin resistance (IR) occurs in 50-70% of women with polycystic ovary syndrome (PCOS) and can be applied as a prediabetic feature in PCOS. OBJECTIVE: In this study, indirect methods including fasting blood sugar (FBS), fasting insulin (FI), FBS/FI ratio, and quantitative insulin sensitivity check index (QUICKI) were compared with the homeostasis model assessment of insulin resistance (HOMA-IR) as a standard technique. The association of IR to sex hormone-binding globulin (SHBG) and several hormones was also analyzed. MATERIALS AND METHODS: This cross-sectional study was performed on 74 PCOS women. Sensitivity and specificity of each IR method was calculated based on HOMA-IR. Hormonal profiles of the patients were compared between the groups with defined normal and abnormal values of IR. RESULTS: Triglyceride levels had a positive association with FBS and HOMA-IR (p = 0.002 and p = 0.01, respectively) with a negative association to QUICKI and SHBG (p = 0.02 and p = 0.02, respectively). SHBG showed a significant negative association with FBS (p = 0.001). Dehydroepiandrosterone sulfate showed a positive association with FI (p = 0.002). Seven PCOS women showed abnormal SHBG levels ( < 36 nmol/L) while expressed normal values of the rest of the studied variables. FI and QUICKI had the highest sensitivity while FBS/FI and QUICKI had the highest specificity when HOMA-IR was applied as a standard test. CONCLUSION: SHBG and triglyceride had a significant negative and positive association with IR, respectively. HOMA-IR followed by FI and QUICKI is the most sensitive test for the detection of IR. SHBG levels can be a helpful biomarker for the diagnosis of PCOS.

RESUMO

BACKGROUND: About 8-12% of couples on reproductive age suffers from infertility worldwide. Since 1993, the role of genital tract infections by microbes, including viruses that can infect the sperm, in human infertility has been proposed. OBJECTIVE: To investigate the frequency of hepatitis B virus (HBV), human papilloma virus (HPV), Epstein-Barr virus (EBV), and herpes simplex virus (HSV) infection in the semen of fertile and infertile men referred to the Mother and Child Hospital, Shiraz, Iran. MATERIALS AND METHODS: In this cross-sectional study, 350 men including 200 infertile and 150 fertile men were included. All semen samples were allowed to liquefy, followed by the assessment of sperm parameters. DNA was extracted using a DNA extraction kit (CinaGene, Tehran, Iran) according to the manufacturer's instructions. Detection of HBV, HPV, EBV, and HSV1/2 was done by the PCR method. RESULTS: The mean age of the participants was 36 ± 7 yr. Molecular results showed that 16 samples (8%) of infertile men and 5 (3.3%) of fertile men were positive for HBV, which was not statistically significant (p = 0.069). Only one sample of the fertile participants was positive for HPV. None of the semen samples of the infertile or fertile groups was positive for the presence of EBV or HSV1/2. CONCLUSION: The results of this study indicated that HBV, HPV, EBV, and HSV might not be involved in men's infertility. Further studies are recommended for clarifying the role of these viruses in infertility.

RESUMO

INTRODUCTION: Infertility considered as a social and public health issue and estimated that most of these infertile couples are residents of developing countries. Infectious diseases including the history of Sexually Transmitted Infections (STIs) may impact on male reproductive function. Therefore, the present study aimed to investigate the prevalence of bacterial contaminants of semen and probable association with sperm quality of infertile men in Iranian population. METHODS: The study population consisted of 200 infertile men and 150 fertile men attending an infertility Center in southwestern Iran during the study period in 2015. The assessment of sperm parameters was according to the World Health Organization (WHO) guidelines. The presumptive pathogens were identified using standard microbiology tests and confirmed by specific PCR primers. RESULTS: The prevalence of bacteriospermia in the semen of the infertile group was significantly higher than that in the fertile group (48% vs. 26.7%, P <0.001). The microbiological analysis of samples showed that the most abundant species of bacteria in semen of infertile men were Chlamydia trachomatis (12.5%) followed by Neisseria gonorrhoeae (11%). On the other hand, in the control group, Lactobacillus spp. (17.3%) was the most isolated pathogen. Results showed that the presence of N. gonorrhoeae, C. trachomatis, Mycoplasma genitalium, Haemophilus, and Klebsiella was significantly associated with sperm abnormality. CONCLUSIONS: Based on our findings, it seems that bacteriospermia is associated with alterations in the properties of semen which may lead to a decrease in the fertilization potential of sperm. Therefore, immediate and appropriate treatment is necessary before investigating every other possible cause of infertility.

RESUMO

BACKGROUND: Uncomplicated infections such as candidiasis, bacterial vaginosis (BV), or trichomoniasis are easy to diagnose and treat. However, about 8% of patients will have a more complicated course with failure to respond to treatment or rapid recurrence of symptoms. There are many suggestions in Traditional Persian Medicine like myrtle (Myrtus communis L.) and oak gall (Quercus infectoria G.Olivier) for treatment of vaginitis. OBJECTIVES: A clinical trial was designed to assess the efficacy of a novel herbal suppository, containing myrtle and oak gall (MOGS) in treatment of vaginitis. METHODS: In a parallel randomized clinical trial, 120 women with vaginitis were randomly assigned to MOGS, metronidazole, or placebo. Formulation was simulated from traditional Persian manuscripts and MGOS was prepared after pharmaceutical optimization processing as well as quantification of gallic acid by HPLC. The study was double-blind for MOGS and placebo and single-blind for metronidazole group. RESULTS: MOGS effectively improved vaginal discharge (p = 0.024 for BV and 0.018 for trichomoniasis) and pH (compared to placebo (p = 0.013) and metronidazole (p = 0.001)). Both MOGS and metronidazole could reverse whiff test. Metronidazole was the best medication for making Nugent score negative (p = 0.005) as well as the best therapy according to laboratory findings to treat BV in comparison with placebo (p = 0.021). While for trichomoniasis, MOGS could improve the disease more successfully (p = 0.001). Both MOGS and metronidazole treated mixed vaginitis (p = 0.002). CONCLUSION: MOGS would be a chance for developing new treatment for trichomoniasis.

RESUMO

BACKGROUND: Oxidative stress and GSH-dependent antioxidant system plays a key role in the pathogenesis of polycystic ovary syndrome (PCOS). OBJECTIVE: We compared glutathione peroxidase (GPx) and glutathione reductase activities and reduced glutathione (GSH) levels in serum and follicular fluid (FF) of the first-retrieved follicle and their impact on quality of oocyte and embryo in PCOS women undergoing IVF. MATERIALS AND METHODS: This cross sectional study was conducted on 80 pairs of blood samples and FF of the first-retrieved follicle from PCOS women, at the Infertility center of Ghadir Mother and Child Hospital. The mean activity of GPx and GR, also GSH levels in the serum and FF were compared to the quality of the first follicle and resultant embryo. RESULTS: Retrieved oocytes included 53 (66.25%) MII, 17 (21.25%) MI, and 10 (12.5%) germinal vesicles; after IVF 42 (52.50%) embryos with grade I and 11 (13.75%) with grade II were produced. The mean values for all three antioxidants were higher in the FF compared to serum (p < 0.001). Also all of the mean measured levels were significantly higher in the FF of the MII oocytes compared to that of oocytes with lower grades (p = 0.012, 0.006 and 0.012, respectively). The mean GPX activity and GSH levels were significantly higher in the serum (p = 0.016 and 0.012, respectively) and FF (p = 0.001 for both) of the high-quality grade I embryos. CONCLUSION: GSH-dependent antioxidant system functions more efficiently in the FF of oocytes and embryos with higher quality.
