RESUMEN

Polycystic ovary syndrome is the most common cause of oligo-ovulation and anovulation among women of reproductive age, contributing to infertility. This study aimed to compare the effects of green tea tablets and metformin on ovulation, menstrual cycle regularity, and antioxidant biomarkers in women with polycystic ovary syndrome (PCOS). In this clinical trial study, 94 women with PCOS were randomly assigned to three groups: green tea (n = 33), metformin (n = 29), and control (n = 32). Menstrual status and oxidative stress parameters, including total antioxidant capacity, thiol, and lipid peroxidation, were compared before and 3 months after the intervention among all three groups. Data analysis was conducted using SPSS software version 22 and employing the analysis of variance and paired t-tests. Following the intervention, the mean menstrual cycle duration in the green tea, metformin, and control groups was 32.22 ± 12.78, 48.72 ± 37.06, and 48.53 ± 31.04 days, respectively (P = 0.040). There was no statistically significant difference between the three groups in terms of biochemical, hormonal, and antioxidant indices before and after the intervention (P > 0.05). The intake of green tea tablets was associated with better outcomes in regulating the menstrual cycle in women with PCOS.

RESUMEN

Background: People's knowledge and attitude play a role in deciding whether or not to use assisted reproductive procedures (ART). There is no information about people's attitudes and awareness about ART in western Iran. Thus, this study was performed to determine the knowledge and attitude of infertile people toward ART. Methods: This cross-sectional study was performed on 124 infertile participants who referred to the in vitro fertilization section of Fatemieh hospital, Hamadan, Iran. To measure the knowledge and attitude of the participants, 2 researcher-made questionnaires were used. Their validity and reliability were confirmed by content validity (eg, content validity index [CVI]; content validity ratio [CVR] ) and the Cronbach alpha, respectively. Results: The study involved 124 participants, more than half of whom were women (54.8%). The mean of the CVI and the CVR for the attitude questionnaire was 0.76 and 0.79, respectively, and for the knowledge, questionnaire was 0.72 and 0.71, respectively. The Cronbach alpha coefficient obtained for the attitude and knowledge questionnaires was 0.761 and 0.745, respectively. The mean (SD) of the attitude and knowledge of infertile people toward the use of ART was 15.33 ± 2.91 and 9.04 ± 2.92, respectively. The study reported that participants' age, inhabitation, and job status had a significant effect on their attitude score. Also, the study found that the knowledge score was inversely related to age. The knowledge in those who were unemployed and living in the rural and less than those employed and living in urban areas, respectively. Conclusion: The 2 questionnaires designed in this study (knowledge and attitude) have the required validity and reliability. As a result, it appears that increasing people's knowledge and improving their attitude, particularly among the elderly, is necessary.

RESUMEN

Background: Methylenetetrahydrofolate reductase enzyme (MTHFR) plays a key role in regulating folate balance, converting homocysteine to methionine, and producing s-adenosylmethionine (SAM) that plays a role in the methylation process. Objective: This study aimed to determine MTHFR activity and SAM level in men with normozoospermia and oligozoospermia. Materials and Methods: 30 oligozoospermic and 30 normozoospermic men as controls were enrolled in this case-control study. Semen analysis was conducted according to the world health organization criteria. All semen samples were collected after 3-5 days of sexual abstinence. The sperms were evaluated by sperm test video software. All subjects SAM level was measured by enzyme-linked immunosorbent assay kit, and MTHFR were measured manually. Results: 2 groups had a significant difference in sperm morphology (p = 0.02), concentration (p = 0.02) and motility (p = 0.03). The MTHFR activity in normozoospermic and oligozoospermic groups had significantly differences (p = 0.01). The level of SAM in the semen of oligozoospermic men was statistically lower than normozoospermic men (p = 0.03). Also, there was a positive association between MTHFR enzyme activity and SAM level in the normozoospermia group (p = 0.02, ß = 0.67) and oligozoospermia group (p = 0.03, ß = 0.54). Conclusion: MTHFR activity and SAM concentration were statistically lower in oligozoospermia men. It seems they can affect sperm concentration, morphology, and motility.

RESUMEN

BACKGROUND: Endometrial scratch injury is considered controversial in increasing the success rate of assisted reproductive technology. OBJECTIVE: To compare the pregnancy outcomes in women undergoing intrauterine insemination with and without an endometrial scratch. MATERIALS AND METHODS: In this randomized clinical trial, 150 women referred to the Fatemieh Hospital, Hamadan, Iran who were candidates for IUI between December 2017 and December 2018 were randomly assigned into two groups (n = 75/each) with or without an endometrial scratch (as case and control groups, respectively). Women in both groups were in proper and identical protocol for IUI. Chemical and clinical pregnancies, abortion, and live birth rate, also pregnancy complications were compared between the groups. RESULTS: Chemical and clinical pregnancy rates were higher in the case than the control group (p = 0.25, p = 0.54, respectively). In the case group, the abortion and multiple gestation rates were 14.3% and 4.3%, respectively, while it was 5% in the control group (p = 0.60, p = 0.54 respectively). The endometrium thickness on day 21 was higher in the case group than the control (p = 0.01). CONCLUSION: Endometrial scratching in intrauterine insemination women is not associated with an increase in both clinical and clinical pregnancy rates, however, studies with a larger sample size are recommended to evaluate this intervention.

RESUMEN

ABSTRACT Objective: A disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4) and ADAMTS-5 normal expression levels are essential for ovulation and subsequent fertilization. The objective of the present study was to assess expression pattern of these genes in cumulus cells (CCs) taken from patients with polycystic ovary syndrome (PCOS) and to investigate any possible relationship with the oocyte quality. Subjects and methods: ADAMTS-4 and -5 expression levels within CCs containing oocytes at the metaphase II (MII) and germinal vesicle (GV) stages, taken from 35 patients with PCOS and 35 women with normal ovarian function, were investigated using RT-qPCR. Moreover, possible correlations between ADAMTS-4, ADAMTS-5, and progesterone receptors (PRs) expression as well as oocyte quality were evaluated. Results: ADAMTS-4 and -5 expression levels were dramatically diminished in the CCs of the PCOS patients when compared to the controls. ADAMTS-4 and -5 expression levels were correlated with each other and with the oocyte quality. Furthermore, lower expression levels of ADAMTS-4 and -5 in the PCOS patients were strongly correlated with the diminished PRs expression levels. Conclusions: Downregulation of ADAMTS-4 and -5 in the human CCs of the PCOS patients correlated with the decline in the PRs expression, and impaired oocyte quality may cause lower oocyte recovery, maturation, and fertilization rate.

RESUMEN

Asherman's syndrome (AS) is an endometrial damage that results in infertility in women. Although stem cell therapy has been introduced as a potential treatment for this syndrome, its use in clinical settings remains challenging because of the likelihood of contamination and cell differentiation. Herein, we investigated the effects of adipose-derived stromal vascular fraction (SVF) transplantation on proliferation and angiogenesis in the endometrium in an AS model. The AS model was induced using scratch method in adult male Wistar rats, and SVF (5 × 10 (Simsir et al., 2019) cells) was locally administered into the damaged horns. Two weeks after cell transplantation, endometrial thickness, fibrosis, and expression of vascular endothelial growth factor (VEGF) were assessed by Hematoxylin & Eosin, Masson's trichrome, and immunofluorescence staining, respectively. We found thin endometrium, increased fibrosis, and decreased VEGF following AS induction all of which were reversed after SVF transplantation. We concluded that the local injection of SVF may serve as an effective alternative therapy for AS.

RESUMEN

PURPOSE: Cell therapy is a promising strategy for the treatment of Asherman's syndrome (AS), but the origin of these cells and injection route influence the therapeutic effect and complications of cell therapy. Herein, we compared the effects of systemic or local intrauterine injection of bone marrow or adipose-derived mesenchymal stem cells (BMSCs/AMSCs) on the endometrium in a rat model of AS. METHODS: After induction of AS in adult Wistar rats, the CM-Dil-positive BMSCs or AMSCs were injected either locally or intravenously. After 3 weeks, endometrial thickness, collagen deposition, cell migration, and VEGF expression were evaluated using histochemistry/immunofluorescence studies. RESULTS: In all stem cell-treated groups, an ameliorative effect on the damaged endometrium was noted. Collagen deposition diminished in both groups (IV and local injection) compared to the AS model. In rats injected locally with MSC, fibrosis decreased compared to the other groups. Moreover, endometrial thickness increased in the groups that received local injection of BMSCs and AMSCs more than the IV-transplanted AMSCs group. Immunofluorescent staining demonstrated that although the systemic transplantation of BMSCs was more effective than the other groups on VEGF expression, it led to the lowest number of CM-Dil+ stem cells in the damaged endometrium. CONCLUSION: Stem cell transplantation may reconstruct the damaged endometrium, but it is recommended to select the most effective stem cells and injection route. Because the removal of the fibrosis and the replacement of the epithelia cells is an effective therapeutic strategy for AS, in this study, we conclude that the local injection of AMSCs is more appropriate than BMSCs to treat AS.

RESUMEN

BACKGROUND: Assisted reproductive technologies (ARTs) such as in vitro fertilization (IVF) can lead to depressive symptoms in infertile women due to their low success and high costs. Mindfulness-based group counseling can decrease depressive symptoms by increasing mental concentration. The aim of the present study was to evaluate the effect of mindfulness-based group counseling on depression in infertile women undergoing IVF. MATERIALS AND METHODS: The present clinical trial included 90 infertile women undergoing IVF treatment in an infertility center in 2016. Women were divided into two groups, intervention and control. Both groups completed a demographic questionnaire and the Beck depression inventory (BDI). Eight 90-minute sessions (two each week) of mindfulness-based group counseling were held with the intervention group, while the control group received treatment as normal. Following the intervention, the BDI was again completed by both groups. The data were analyzed and independent t tests and, paired t tests conducted at a significance level of P<0.05. RESULTS: No statistically significant demographic differences were observed between the two groups. Women in the control group had a somewhat lower depressive symptom score than the intervention group before the intervention. However, compared with before, the depressive symptom score among women in the intervention group decreased significantly (48%) (P<0.001) after the intervention. In contrast, the depressive symptom score in control women was higher after the intervention than before. CONCLUSION: According to the findings of the present research, mindfulness-based group counseling is able to reduce depressive symptoms in infertile women under IVF treatment. Therefore, group counseling sessions are suggested for all depressed women undergoing infertility treatment (Registration number: IRCT2015082013405N14).

RESUMEN

PURPOSE: ADAMTS-1 and 9 play a crucial role in the ovulation and their altered levels may play a role in the pathogenesis of polycystic ovary syndrome (PCOS). The aim of this study was to assess ADAMTS-1 and 9 expression and their correlation with the oocyte quality and maturity in the cumulus cells (CCs) of PCOS patients and normovulatory women during an IVF procedure. METHODS: Expression of ADAMTS-1 and 9 and progesterone receptors (PRs) in the CCs containing MII and germinal vesicle (GV) oocytes of 37 PCOS patients and 37 women with normal ovulatory function who underwent IVF treatment was evaluated using qRT-PCR. Moreover, correlation between ADAMTS-1 and 9 expression and oocyte quality were also investigated. RESULTS: mRNA expression levels of ADAMTS-1 and ADAMTS-9 were significantly reduced in the women with PCOS compared to the normovulatory women. ADAMTS-1 and ADAMTS-9 mRNA expression levels in the CCs showed a considerable correlation. Lower expression levels of ADAMTS-1 and ADAMTS-9 in PCOS patients were strongly correlated with diminished oocyte maturation. There was a remarkable association between ADAMTS-1 and ADAMTS-9 mRNA expression levels and oocyte quality. PRs (PRA and PRB) were dramatically decreased in PCOS patients when compared with the control group. CONCLUSIONS: The results of the present study indicated that ADAMTS-1 and ADAMTS-9 as well as PRs are downregulated in the human CCs in PCOS patients, which could be associated with impaired oocyte maturation and may result in a lower oocyte recovery and oocyte maturity rates, as well as lower fertilization rate.

RESUMEN

PURPOSE: The purpose of the study was to investigate changes in adiponectin system expression in granulosa cells (GCs) and high molecular weight adiponectin levels in serum and follicular fluid (FF) of 40 women with polycystic ovary syndrome (PCOS) compared to those in 40 women with normal ovary function. METHODS: Adiponectin (Adipo), adiponectin receptor 1 (AdipoR1), and adiponectin receptor 2 (AdipoR2) messenger RNA (mRNA) expression levels were measured using quantitative real-time polymerase chain reaction (qRT-PCR). High molecular weight (HMW) adiponectin protein concentration was evaluated by ELISA method. Data were analyzed using Student's t test and one-way ANOVA in SPSS 21 software. At oocyte retrieval, FF was aspirated and GCs were obtained from a pooled collection of FF per each patient. RESULTS: PCR results showed expression of adiponectin, AdipoR1, AdipoR2, follicle-stimulating hormone receptor (FSHR), and luteinizing hormone receptor (LHR) in GCs. After controlling body mass index (BMI) values, qRT-PCR demonstrated a decreased expression of adiponectin system in GCs of PCOS patients compared to those in controls (p = 0.001). There was a strong positive correlation among AdipoR1 and AdipoR2 expression and also among FSH and LH receptor expression. (Both r = 0.8, p = 0.001). There were low levels of high molecular weight adiponectin in the serum of PCOS patients with controlled ovarian hyperstimulation (30.19 ± 4.3 ng/ml) compared to the controls (48.47 ± 5.9 ng/ml) and in the FF of PCOS patients with controlled ovarian hyperstimulation (7.86 ± 1.44 ng/ml) compared to the controls (14.22 ± 2.01 ng/ml; p = 0.02). CONCLUSIONS: Lower expression of adiponectin and its receptors in GCs might be an important manifestation in gonadotropin-stimulated PCOS patients which could influence the physiologic adiponectin roles such as interaction with insulin and LH in induction of GC gene expression.

RESUMEN

Background: Birth weight and gestational age are two important variables in obstetric research. The primary measure of gestational age is based on a mother's recall of her last menstrual period. This recall may cause random or systematic errors. Therefore, the objective of this study is to utilize Bayesian mixture model in order to identify implausible gestational age. Methods: In this cross-sectional study, medical documents of 502 preterm infants born and hospitalized in Hamadan Fatemieh Hospital from 2009 to 2013 were gathered. Preterm infants were classified to less than 28 weeks and 28 to 31 weeks. A two-component Bayesian mixture model was utilized to identify implausible gestational age; the first component shows the probability of correct and the second one shows the probability of incorrect classification of gestational ages. The data were analyzed through OpenBUGS 3.2.2 and 'coda' package of R 3.1.1. Results: The mean (SD) of the second component of less than 28 weeks and 28 to 31 weeks were 1179 (0.0123) and 1620 (0.0074), respectively. These values were larger than the mean of the first component for both groups which were 815.9 (0.0123) and 1061 (0.0074), respectively. Conclusion: Errors occurred in recording the gestational ages of these two groups of preterm infants included recording the gestational age less than the actual value at birth. Therefore, developing scientific methods to correct these errors is essential to providing desirable health services and adjusting accurate health indicators.

RESUMEN

BACKGROUND: Infertility is considered as a major health care problem of different communities. The high prevalence of this issue doubled its importance. A significant proportion of infertility have been related to environmental conditions and also acquired risk factors. Different environmental conditions emphasized the need to study the different causes of infertility in each area. OBJECTIVE: The aim of this study was to determine the frequency causes of infertility in infertile couples. MATERIALS AND METHODS: In this cross sectional descriptive study 1200 infertile men and women that were referred to infertility clinic of Fatemieh Hospital during 2010 to 2011, were examined. This center is the only governmental center for infertility in Hamadan. Sampling was based on census method. Information about the patients was obtained from medical examinations and laboratory findings. To analyze the data, descriptive statistics such as frequencies and the mean were used. RESULTS: The prevalence of primary and secondary infertility was 69.5% and 30.5% respectively. Among the various causes of infertility women factors (88.6%) had the highest regard. In the causes of female infertility, menstrual disorders, diseases (obesity, thyroid diseases, and diabetes), ovulation dysfunction, uterine factor, fallopian tubes and cervical factor had the highest prevalence respectively. The causes of male infertility based on their frequency included semen fluid abnormalities, genetic factors, vascular abnormalities, and anti-spermatogenesis factors, respectively. CONCLUSION: Etiology pattern of infertility in our study is similar with the many other patterns that have been reported by the World Health Organization. However, frequency of menstrual disorders is much higher than other studies that require further consideration.

RESUMEN

BACKGROUND: High Cesarean section rate is a major health problem in developing countries. This study was established to evaluate the effectiveness of Iranian Ministry of Health and Medical Education protocols on Cesarean section rate trend. METHODS: Through a non-concurrent controlled quasi-experimental study, Cesarean section rate in Shohada-e-Tajrish and Taleghani hospitals in Tehran was compared during 2008-2009. Intervention group included 578 participants hospitalized because of premature rupture of membranes, prolonged pregnancy, pre-eclampsia, intra-uterine growth retardation, vaginal bleeding and premature labor in first and second trimester underwent interventions based on MOHME new protocol. On the other hand 594 cases as control group were selected during the same time before the intervention and underwent routine treatments. Descriptive statics, t-test, chi square and univariate analysis were used when appropriate. RESULTS: Basic characteristics in two groups had no statistically significant difference. Cesarean section applied for 360 (67.8%) women in case group and on the other hand, 270 (48.8%) Cesarean sections were done for control group (P<0.001). There was 19 % difference between intervention and control groups. Complication of pregnancies had increased by 6% in intervention group (P<0.001). Mortality rate in the study was zero in both groups. CONCLUSION: Applying clinical practice guidelines does not guarantee decreasing Cesarean section rate. Providing appropriate service may increase the ability of service providers to find more indications for Cesarean section.

RESUMEN

The most common anatomic variant seen in the donor kidneys for renal transplantation is multiple renal arteries (MRA), which can cause an increased risk of complications. We describe the long-term outcomes of 16 years of experience in 76 kidney transplantations with MRAs. In a new reconstruction technique, we remove arterial clamps after anastomosing the donor to the recipient's main renal vessels, which cause backflow from accessory arteries to prevent thrombosis. By this technique, we reduce the ischemic times as well as the operating times. Both in live or cadaver donor kidneys, lower polar arteries were anastomosed to the inferior epigastric artery and upper polar arteries were anastomosed to the superior epigastric arteries. Injection of Papaverine and ablation of sympathic nerves of these arteries dilate and prevent them from post-operative spasm. Follow-up DTPA renal scan in all patients showed good perfusion and function of the transplanted kidney, except two cases of polar arterial thrombosis. Mean creatinine levels during at least two years of follow-up remained acceptable. Patient and graft survival were excellent. No cases of ATN, hypertension, rejection and urologic complications were found. In conclusion, this technique can be safely and successfully utilized for renal transplantation with kidneys having MRAs, and may be associated with a lower complication rate and better graft function compared with the existing techniques.

RESUMEN

BACKGROUND: This study was conducted to determine the total expenditure and out of pocket payment on pregnancy complications in Tehran, the capital of Iran. METHODS: A cross-sectional study conducted on 1172 patients who admitted in two general teaching referral Hospitals in Tehran. In this study, we calculated total and out of pocket inpatient costs for seven pregnancy complications including preeclampsia, intrauterine growth restriction (IUGR), abortion, ante-partum hemorrhage, preterm delivery, premature rupture of membranes and post-dated pregnancy. We used descriptive analysis and analysis of variance test to compare these pregnancy complications. RESULTS: The average duration of hospitalization was 3.28 days and the number of visits by physicians for a patient was 9.79 on average. The average total cost for these pregnancy complications was 735.22 Unites States Dollars (USD) (standard deviation [SD] = 650.53). The average out of packet share was 277.08 USD (SD = 350.74), which was 37.69% of total expenditure. IUGR with payment of 398.76 USD (SD = 418.54) (52.06% of total expenditure) had the greatest amount of out of pocket expenditure in all complications. While, abortion had the minimum out of pocket amount that was 148.77 USD (SD = 244.05). CONCLUSIONS: Obstetrics complications had no catastrophic effect on families, but IUGR cost was about 30% of monthly household non-food costs in Tehran so more financial protection plans and insurances are recommended for these patients.

RESUMEN

UNLABELLED:   BACKGROUND: During the month of Ramadan, millions of Muslims abstain from food and drink daily from dawn to sunset and people actually experience repeated cycles of fasting and refeeding. Menstruation is a normal physiological process that its regularity is controlled by hypothalamic-pituitary-ovarian axis. Etiology of menstrual dysfunction includes weight loss, hypoleptinemia, abnormal eating behaviors, exercise, and psychological stressors. OBJECTIVE: To investigate the effects of Ramadan fasting on menstrual cycles. MATERIALS AND METHODS: This analytic cross-sectional study was performed on 80 female college students resident in a dormitory of Hamedan University of Medical Sciences. A questionnaire including demographic characteristics and menstrual calendar was filled by all participants. All analyses were performed using the statistical software SPSS for Windows version 11.5. RESULTS: We found 11.3%, 30%, and 16.3% of participates had abnormal menstrual pattern three months before, during and three months after Ramadan, respectively. In participates who fast more than 15 days, menstrual period had significantly more abnormality than participants who fast less than 15 days. Considering our results we demonstrated that menstrual abnormalities during Ramadan month reach to their peak and three months after Ramadan reduce but do not return to previous condition. CONCLUSION: This study confirms that menstrual abnormalities including oligomenorrhea, polymenorrhea and hypermenorrhea increased during Ramadan especially in participates with more than 15 days of fasting.

RESUMEN

BACKGROUND: The most frequent physical finding in infertile men is varicocele, in which one of the mechanisms that can affect seminal parameters is oxidative stress. OBJECTIVE: Our study aimed, for the first time, to compare the efficacy of recombinant human follicle-stimulating hormone (rhFSH), human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) on sperm parameters and fertility after varicocelectomy. MATERIALS AND METHODS: 113 infertile men with varicocele were divided into four groups. Group A received HCG 5000 IU weekly, group B received HMG 75 IU three times a week, group C received rhFSH 75 IU three times a week and group D received no medical treatment after varicocelectomy. RESULTS: After three months, in group A sperm morphology improved (p=0.007), causing a 32% pregnancy rate. In group B, sperm motility (p=0.023) and morphology (p=0.014) improved, causing a 57% pregnancy rate. In group C, all of the investigated semen parameters increased (p<0.05), causing a 62.5% pregnancy rate. Only rhFSH improved sperm concentrations to >20×10(6) mL (p=0.027). In group D, sperm morphology increased (p=0.038), but other parameters remained unchanged and no pregnancies occurred. CONCLUSION: It can be concluded that drugs can reduce induction time for spermatogenesis and fertility in comparison with varicocelectomy alone. For these purposes, rhFSH is more effective than other drugs.

RESUMEN

We aimed to assess the long-term toxic effects of sulphur mustard (SM) on the testis and male fertility two decades after exposure. A historical cohort study was conducted in 2005. Sixty-four SM-exposed and 64 matched SM-unexposed casualties of the Iraq-Iran conflict were enrolled. Fecundity status, semen indices, hormonal assay results and testis histopathology were evaluated. Male factor infertility was diagnosed in 23 and 5% of married exposed and unexposed casualties, respectively (p < 0.01). All semen indices declined over the 15 years since 1990 among the exposed group. Furthermore, all indices with the exception of sperm motility were significantly lower in the exposed than in unexposed men. The follicle-stimulating hormone level was higher in the infertile than in fertile exposed men (p < 0.001). Testis histopathology of the azoospermic men showed complete absence of spermatogenesis with only Sertoli cells in the seminiferous tubules. SM can be gonadotoxic and its chronic toxicity may be permanent. Germ cells are probably the most susceptible gonadal cells to SM.
