Abstract

Backgroud: Intrauterine insemination (IUI) is generally attempted before proceeding to more expensive and invasive assisted reproductive techniques such as invitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). This procedure is most commonly performed as a therapeutic method for couples with a wide variety of subfertility etiologies, such as low count or low motility of sperm, or an incompatibility between the sperm and the cervical mucus. The objective of this clinical trial study was to compare the correlation between the semen parameters and pregnancy rates in patients undergoing hyperstimulation and IUI. Materials and Methods: 336 infertile couples that underwent 336 cycles of IUI with washed husband�s semen were included in this study. All patients� charts were reviewed for age, etiology and duration of infertility, semen characteristics and pregnancy rates. The SPSS 9 software and Chi-square tests were applied for statistical analysis. P<0.05 was determined as statistical significance. Results: Total pregnancy rates were18.2% (61 out of 336 cycles). Postwash semen parameters including: sperm count ?10? 106 ,motility ?50% (grade III and IV >20%) had significant effect on pregnancy rates after IUI. The Outcome of this procedure was not significantly affected by female age, duration or etiology of infertility. Conclusion: Postwash semen quality was the most important factor for predication of successful pregnancy in this study.

Abstract

Background: The etiologic cause in near one third of male factor infertility is unknown. The percentage of men with idiopathic infertility who have been successfully treated by the empirical therapeutic modalities is not high. Objective: The aim of this study was to assay the effect of L-carnitine on sperm parameters in patients who needs intracytoplasmic sperm injection (ICSI) as a method for infertility treatment. Materials and Methods: The study population consisted of 65 men (mean age± SD: 34.4 ± 6.07) presenting with primary infertility due to idiopathic oligoasthenoteratozoospermia. L-carnitine was prescribed 1gram orally every 8 hours for 3 months. Before and after the ending of the L-carnitine treatment, semen analysis was performed. Results: The proportion of patients who had motile and grade C sperms rose significantly after treatment. Percentile of abnormal shaped sperms decreased significantly after treatment. In approximately 22%, complete asthenozoospermia changed to relative asthenozoospermia. Conclusion: Appearing motile sperms will potentially improve the technique of ICSI. The magnitude of the elevation in normal morphology is not clinically obvious, but it seems that it can be important in obtaining normal-shaped sperms for intracytoplasmic injection. Designing a study on selected patients with complete asthenozoospermia who have not other abnormalities in semen parameters can reveal the real effect of carnitine therapy in this category. Article

Abstract

Background: Female sexual dysfunction (FSD) is a real problem that affects 25-63% of women. There is no valid Persian version of sexual function questionnaire (FSQ).
Objectives: The aim of this study was to test the reliability and validity of Persian version of sexual function questionnaire.
Materials and Methods: In this cross-sectional study, 547 women were questioned by Persian version of SFQ. Factor analysis produced five domains of female sexual function. Internal consistency, test-retest reliability, and discriminant validity were calculated.
Results: Five-factor structure accounted for 63% of the variance. Arousal-orgasm domain was as same as arousal-sensation, arousal-lubrication, and orgasm domains of the original version. Enjoyment-desire domain was similar to enjoyment and desire domains except one question. Pain and partner domains were consistent with original domains. Internal consistency, test-retest reliability, and discriminant validity were reasonable in Persian version of SFQ.
Conclusion: Persian version of SFQ is almost valuable and reliable to use for Iranian population with exception of one question. Results of the omitted question from enjoyment domain should interpret separately as unusual sex domain.

Abstract

Background: Today there is a rise in the number of newborns conceived by artificial reproductive techniques (ART). Numerous studies have been performed on the perinatal outcome of these pregnancies. However, there is limited data about the condition of health of these newborns in Iran. Objective: Regarding the higher prevalence of probable complications and symptomatic congenital anomalies, we aimed to determine the state of health of newborns born by ART.
Materials and methods: A total of 109 newborn who were conceived through ART and 479 newborns of spontaneous conception were enrolled into our study. The study was prospective, case-control study in Tehran, Iran, from March 2003 to March 2004. Both case and control groups were adjusted in regard to race, sex, type of delivery, chronic disease of mother, age of mother, and antenatal steroids administration. All newborns were examined by neonatologist after birth and their outcome were followed until hospital discharge or death. Data pertaining to clinical and laboratory findings of newborns and death were entered into a questionnaire and subsequently analyzed by appropriate statistical tests. Confidence interval was 95%.
Results : Prematurity, low birth weight (LBW), very low birth weight (VLBW), twins and triplets, small for gestational age (SGA), need for resuscitation at birth, respiratory distress syndrome (RDS) and NICU admission were significantly higher among newborns born after ART than those born through spontaneous conception (p<0.05). Regression logistic analysis showed that RDS and NICU admission were more strongly associated with weight at birth and gestational age than with method of conception. However, increased rate of SGA in the case group was associated with multiple pregnancy. Also, there was no significant statistical relationship between the method of conception and the prevalence of congenital anomalies, large for gestational age (LGA), congenital pneumonia, necrotizing entrocolitis (NEC), respiratory air leakage syndromes (ALS), hydrops fetalis, hyperbilirubinemia sepsis, meconium aspiration syndrome (MAS), isseminated intravascular coagulopathy (DIC), cardiac failure, lung hemorrhage, hypoglycemia, hypocalcemia, neutropenia, thrombocytopenia and hemolysis.
Conclusion: Newborns who were conceived by ART were more likely in need of resuscitation at birth regardless of other factors. Furthermore, newborns born after ART were at higher risk of developing prematur birth, LBW, and multiple birth.

Abstract

Background: Severe preeclampsia is a quite well-known entity with high incidence of both maternal and fetal morbidity and mortality. Although little is known about its etiology, inherited disorders of hemostasis and antiphospholipid syndrome have been postulated as common causes. The present study was conducted to evaluate the association of these two entities with preeclampsia in a group of Iranian patients.
Materials and Methods: A case-control study was performed on 26 parturients with severe preeclampsia and 26 healthy pregnant women who were matched according to the age, parity, gestational age and previous history of abortion. A 10cc blood sample was obtained and the following factors were measured: factor V Leiden, protein S, protein C, antithrombin III, anticardiolipin antibodies (IgM and IgG) and the presence of the lupus anticoagulant antibody.
Results: We have not found any significant difference in the values of factor V Leiden, antithrombin III, protein C, protein S, and anticardiolipin-IgG between preeclamptic (case) and non-preeclamptic (control) parturients. Meanwhile, lupus anticoagulant antibody was detected in one case and one control. However, anticardiolipin IgM was shown to be significantly higher in the preeclamptic patients. Severe preeclamptic parturients were 4.4 times more likely to develop elevated levels of IgM (OR=4.4, 95% CI=1.9-10, p<0.05).
Conclusion: Our results failed to reveal any significant association between preeclampsia and indices of inherited disorders of hemostasis, except for anticardiolipin IgM. Thus, routine screening of these indices are not recommended due to high expenses and shortness of reliability.

Abstract

Background: Ectopic pregnancy is one of the pathologic entities that it destroys the fallopian tube and impairs the future pregnancy. There are different medical and surgical therapies in order the treatment and reserve of fertility. The aim of this report is discuss a case of successful intrauterine after management of ectopic pregnancy with local injection of KCL in an infertile PCOD patient.
Case: The patient was a PCOD woman with gestational age of 8.5 weeks. One gestational sac and alive fetus with normal heart beat was seen in the right adnexa. Hemodynamic situation was stable. 0.5cc KCL 10% was injected to the fetal heart and the extracted tissue sent for pathology. We evaluated the effects of this treatment by measuring serial human chorionic gonadotropin (hCG) titers. Moreover, we used hysterosalpingogrphy to diagnose and to evaluate the patency of the tubes. Induction ovulation and intrauterine insemination was done and pregnancy occurred. Patient passed the pregnancy very good and she delivered by cesarean section due to breech presentation at 39 weeks of gestational age. There was no sign of pathologic finding in the tubes or adhesion or sequel of ectopic pregnancy.
Conclusion: The beneficial outcomes of this kind of treatment suggest that local injection of KCL as a low invasive treatment can be the choice treatment for alive and progressed ectopic pregnancy or heterotopic pregnancy. Because of rarity of this management and successful intrauterine we reported the usefulness of local KCL injection for the successful conservative treatment of alive ectopic pregnancy in Iran.

Abstract

Background: The risk of multiple pregnancies often present in programs of In Vitro Fertilization (IVF) is an important force for embryo cryopreservation. On the other hand ethical restriction and assurance of potential fertility following chemo/radio therapy has led scientists to focus on female gamete preservation.
Objective: Optimizing vitrification protocol by using less concentrated cryoprotectants (CPAs) in order to decrease CPAs toxicity.
Materials and Methods: Mouse Metaphase-II (M-II) oocytes and four cell-stage embryos were collected. Oocytes Survival Fertilization and Developmental Rates (SRs FRs DRs) were recorded after cryotop-vitrification/warming. As well as comparing fresh oocytes and embryos the data obtained from experimental groups (exp.) applying 1.25 1.0 0.75 molar (M) CPAs were analyzed in comparison to those of adopting 1.5 M CPAs [largely-used concentration of Ethylen Glycol (EG) and Dimethyl-sulphoxide (DMSO)].
Results: The data of oocytes exposed to 1.25 M concentrated CPAs were in consistency with those exposed to 1.5 M and control group in terms of SR FR and DR. As less concentration was applied the more decreased SRs FRs and DRs were obtained from other experimental groups. The results of embryos which were exposed to 1.25 M and 1.0 M were close to those vitrified with 1.5 M and fresh embryos. The results of 0.75 M concentrated CPAs solutions were significantly lower than those of control 1.5 M and 1.0 M treated groups.
Conclusion: CPAs limited reduction to 1.25 M and 1.0 M instead of using 1.5 M for oocyte and embryo cryotop-vitrification procedure may be a slight adjustment.

Abstract

Background: Reviewing the literature reveals that pentoxifylline (PTX) plus tocopherol (vitamin E) are used mainly to promote sperm quality. However trials focusing on the effects of these drugs in female partner are limited. Combination of pentoxifylline and vitamin E appeared to improve the pregnancy rate in patients with a thin endometrium by increasing the endometrial thickness and improving ovarian function.
Objective: To determine whether combined PTX and tocopherol treatment can improve clinical pregnancy rate.
Materials and Methods: One hundred twelve infertile women undergoing standardized controlled ovarian hyperstimulation for ICSI- ZIFT entered this randomized clinical trial. Patients were randomized to equal groups of combined PTX and tocopherol therapy or none (not receiving PTX and tocopherol). These drugs were administered to the intervention group for two cycles before starting ICSI-ZIFT cycle. Main outcome measure was clinical pregnancy rate. SPSS.11 software (SPSS Inc. Chicago IL.) was used for data collection and analysis.
Results: The clinical pregnancy was higher in the intervention (combined PTX and tocopherol) group in comparison to the other group (57.14% vs 39.29% p=0.01). However there was no difference in the mean endometrial thickness number of retrieved oocytes the number of metaphase II oocytes and grade of them in both groups.
Conclusion: This study showed that PTX plus tocopherol could improve the ZIFT outcome in infertile couples. Local effects and anti oxidative characteristics of these drugs may be the cause of better results.

Abstract

Background: Anti-mullerian hormone (AMH) levels may represent the ovarian follicular pool and could be a useful marker of ovarian reserve. The clinical application of AMH measurement has been proposed in the prediction of quantitative and qualitative aspects in assisted reproductive technologies. Objective: This study aimed to assess the relationship between the serum levels of AMH and results of assisted reproductive technique (ART) outcome in polycystic ovary syndrome (PCOS) patients versus control group.
Materials and Methods: This cohort study was conducted on 61 (PCOS) patients and 28 patients without PCOS (controls) candidates for assisted reproductive technique. Serum levels of AMH were measured on the 3rd day of menstrual cycle and all the patients underwent controlled ovarian hyper stimulation and ART. The relationship between AMH serum level with retrieved oocytes, mature oocytes and pregnancy rate were assessed.
Results: There was significant correlation between the AMH level with number of total retrieved oocytes and mature oocytes in patients with PCOS and controls (p=0.001). In PCOS and control groups AMH level in pregnant patients was higher, but it was not statistically significant (p=0.65, p=0.46, respectively). The major outcome of the study (pregnancy) did not differ significantly between two groups.
Conclusion: This study revealed that AMH level was higher in pregnant patients undergoing ART; but AMH may not be an accurate predictor for pregnancy in PCOS patients.

Abstract

Background: Detection of best predictor of ovarian reserve in patients with temporarily or consistently elevated early follicular phase serum levels of FSH is one of the most important goals in assisted reproductive technique (ART).
Objective: To evaluate whether high level of anti-mullerian hormone level is related to success of ART in patients with temporarily or consistently elevated early follicular phase serum levels of FSH.  
Materials and Methods: Sixty three women underwent intracytoplasmic sperm injection (ICSI) with GnRH-agonist long protocol or intrauterine insemination (IUI) in a prospective cohort study. FSH, inhibin B and anti-Mullerian hormone (AMH) levels were measured in these women whom were divided to three groups (persistently elevated FSH, variably elevated FSH and, normal FSH level). Basal characteristics, stimulation parameters, and pregnancy occurrence were evaluated.
Results: AMH was significantly higher in women with persistently elevated early follicular phase FSH achieving pregnancy. Women with normal FSH did not have significant difference in AMH level between conceived and non conceived cycles. Women with only one elevated early follicular phase FSH achieving pregnancy did not have significant difference in AMH level with non pregnant women. Response to gonadotropin stimulation, recommendation to oocyte donation significantly differed between the groups.
Conclusion: This study has demonstrated that relatively young women with persistently or intermittently elevated day 3 FSH levels have diminished ovarian reserve and lower ART success. However, in women whose FSH levels were constantly elevated, AMH (not inhibin B) concentrations were significantly higher in ART cycles resulting in pregnancy. Therefore, AMH level is a good predictor of ART outcome in patients with elevated early follicular phase serum levels of FSH.

Abstract

Background: Polycystic ovarian syndrome is one of the most common causes of endocrine disorders and main reason of infertility due to anovulation and recurrent abortions. Progesterone has been shown to have an important role in fertilization of oocyte and fetal implantation.
Objective: The purpose of this study was to compare the predictive value of progesterone level on IVF success in women with infertility due to tubal factor or PCOS.
Materials and Methods: In a stratified cohort study, we assigned 76 infertile women of 20-38 years old who referred to women hospital into two equal groups with fallopian tube factor infertility and PCOS. We measured the plasma levels of progesterone and estradiol on the day of HCG administration. The patients were divided into two groups based on progesterone level cut off point of 1.2ng/ml. Thereafter the incidence of pregnancy (chemical by β-HCG measurement and clinical by ultrasonography up to the 6 weeks after fetal transfer) was compared in these groups.
Results: Total pregnancy rates were 15.8% in patients with tubal factor infertility and 26.3% in women with PCOS. In women with PCOS, the pregnancy rate was less in patients with progesterone level <1.2 ng/ml. However this difference was not statistically significant. Likewise, we did not observe any significant differences in pregnancy rate in patients with fallopian tube factor infertility.
Conclusion: Serum progesterone level on the day of HCG administration is not well predictive of the IVF success in infertile women due to fallopian tube factor or PCOS. To obtain more uniform results, we recommend use of larger samples while the bias variable is taken into account and the ROC curve is used for determination of the unique serum progesterone level.

Abstract

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 >20×106 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.

Abstract

Background: Polycystic ovary syndrome (PCOS) causes an increased risk of metabolic cardiovascular syndrome. Also, cystatin C serum levels are associated with the risk of cardiovascular events in metabolic syndrome patients.
Objective: To investigate the relationship between cystatin C in PCOS patients.
Materials and Methods: 35 women with PCOS were compared to 35 women with healthy matched age and body mass index. They all underwent tests to determine plasma levels of C-reactive protein (CRP), cystatin C, lipid profile and apo-lipoprotein. Blood pressure and demographic variables of each subject were obtained.
Results: Systolic and diastolic blood pressure were higher in PCOS patients compared to control group. Triglyceride and low-density lipoprotein cholesterol levels were higher in PCOS; contrariwise, high-density lipoprotein was lower from that of healthy volunteers. Cystatin and CRP levels were significantly higher in patients with PCOS in comparison with healthy subjects (p<0.0001). Among measured determinants, only PCOS status was independently associated with cystatin C.
Conclusion: Cystatin C was positively correlated with PCOS status concentrations but not with systolic and diastolic blood pressure, or any of the lipid profile variables or demographic characteristics. Indeed, no correlation was found between cystatin C and CRP levels. Therefore, cystatin C might be related to PCOS beyond its use as a marker of the renal function.

Abstract

Background: Doxorubicin (DOX), an anthracycline antibiotic, is a widely used anticancer agent. In spite of its high antitumor efficacy, the use of DOX in clinical chemotherapy is limited due to diverse toxicities, including gonadotoxicity.
Objective:  We investigated the protective effect of nano-zinc oxide (nZnO) as an established antioxidant on DOX-induced testicular disorders.
Materials and Methods:  In this experimental study 24 adult male Wistar rats were divided into four groups including one control and three experimentals (6 rats per group). They received saline (as control), DOX alone (6 mg/kg body weight, i.p.), nZnO alone (5 mg/kg body weight, i.p.), and nZnO followed by DOX. Animals were sacrificed 28 days after treatment and evaluations were made by sperm count and measuring sex hormone levels in plasma. Also total antioxidant power (TAP) and lipid peroxidation (LPO) in plasma were tested. Data was analyzed with SPSS-14 and one way ANOVA test. P<0.05 were considered to be statistically significant.
Results:  In the DOX-exposed rats significant differences were found compared with the control group (p=0.001) in plasma total antioxidant power (TAP) (425.50±32.33 vs. 493.33±18.54 mmol/mL), Lipid peroxidation (LPO) (3.70±0.44 vs. 2.78±0.68 μmol/mL), plasma testosterone (3.38±0.69 vs. 5.40±0.89 ng/dl), LH (0.26±0.05 vs. 0.49±0.18 mlU/mL), sperm count (157.98±6.29 vs. 171.71±4.42×106/mL) and DNA damage (11.51±3.45 vs. 6.04±2.83%). Co-administration of nZnO significantly improved DOX-induced changes (p=0.013) in plasma TAP (471.83±14.51 mmol/mL), LPO (2.83±0.75 μmol/mL), plasma testosterone (5.00±1.07 ng/dl), LH (0.52±0.08 mlU/mL), sperm count (169.13±5.01×106/mL) and DNA damage (7.00±1.67%).
Conclusion:  At the dose designed in the present investigation cytoprotective role of nano-zinc oxide through its antioxidant potential is illuminated in DOX-induced male gonadotoxicity.

Abstract

Background: In patients with non-obstructive azoospermia (NOA), vital spermatozoa from the tissue is obtained from testes by enzymatic treatment besides the mechanical treatment.
Objective: To increase the sperm recovery success of testicular sperm extraction (TESE), with enzymatic digestion if no sperm is obtained from testis tissue by mechanical method.
Materials and Methods: Tissue samples were collected from 150 men who presented with clinical and laboratory data indicating NOA by means of TESE and micro dissection TESE methods. Initially, mature spermatozoa were examined for by mechanical extraction technique shredding the biopsy fractions. In cases whom no spermatozoa was observed after maximum 30 min of initial searching under the inverted microscope, the procedure was followed by enzymatic digestion using DNaseI and collagenase type IV. Surgery type, pathology, AZF, karyotype, hormones and testis size were compared in patients.
Results: Of 150 cases with NOA, conventional mincing method extended with enzymatic treatment yielded successful sperm recovery in 13 (about 9%) patients. Comparison of parameters revealed that level of FSH and LH were significantly different (p=0.04 and 0.08 respectively) between two groups that response negative and positive to enzymatic digestion.
Conclusion: The combination of conventional TESE and enzymatic digestion is an effective method to recover spermatozoa. The benefit of the mincing combined with enzyme to sperm retrieval for NOA firstly shorten the mechanical searching time, leading to minimizing further cellular damage as well as exposure to external conditions, and secondly reduce the number of cases with sperm recovery failures. Also, the serum level of FSH and LH are factors that influence the chance of sperm retrieval.

Abstract

Background: Embryo cryopreservation is the process that water is removed from the cell by cryoprotectant materials, and embryos are stored at temperature below zero. This process may affect the viability and developmental potential of embryos.
Objective: In this study, the effect of the vitrification cryotop method on the expression level of Oct4 and Mest developmental genes in mouse blastocysts was examined.
Materials and Methods: The collected 2-cell embryos of superovulated mouse by oviduct flushing were divided into non-vitrified and vitrified groups. These embryos were cultured to the blastocyst stage directly in the non-vitrified group and in the vitrified group, these embryos were cultured to 4-8 cell embryos, vitrified with cryotop in these stages and after 2-6 months, warmed and cultured to blastocyst embryos. Quantitative expression of two developmental genes, namely Oct4 and Mest, were performed in these groups, using RNA purification and Real-time RT-PCR.
Results: Quantitative PCR analysis showed that the expression level of both genes, Oct4 and Mest, was reduced significantly in the vitrified-warmed group relative to the control group (p=0.046 and p=0.001).
Conclusion: This study revealed that morphologically normal embryos show a reduced amount of Oct4 and Mest transcripts which indicate that the vitrification method negatively effects the expression level of these two developmental genes.

Abstract

Background: The interaction between follicular cells and oocyte leads to a change in gene expression involved in oocyte maturation processes.
Objective: The purpose of this study was to quantify the expression of more common genes involved in follicular growth and oocyte developmental competence.
Materials and Methods: In this experimental study, the expression of genes was evaluated with qRT-PCR assay in female BALB/c mice pups at 3-day of pre-pubertal and 8 week old virgin adult ovaries. The tissue was prepared by H&E staining for normal morphological appearance. The data were calculated with the 2-ΔCt formula and assessed using non-parametric two-tailed Mann-Whitney test. The p<0.05 was considered as significant.
Results: The data showed a significant increase in the level of Stra8 and GDF9 in adult compared with newborn mice ovaries (p=0.049). In contrast, a significant decrease in the level of Mvh, REC8, SCP1, SCP3, and ZP2 was observed in adult mice ovaries compared to those in the newborn mice ovaries (all p=0.049 except SCP1: p=0.046). There was no significant difference in the level of OCT4 and Cx37 expression between adult and newborn mice ovaries.
Conclusion: The modifications in gene expression patterns coordinate the follicular developmental processes. Furthermore, the findings showed higher expression level of premeiotic gene (Stra8) and lower level of meiotic entry markers (SCP1, SCP3, and REC8) in juvenile than newborn mouse ovaries.

Abstract

Background: Ectopic pregnancy is one of the main problems in women in reproductive age that needs special attention and appropriate strategy should be managed. In some cases expectant management seems good strategy without any medicine or surgery and their possible side effects. But are the outcomes always the same? Which outcomes should we expect?
Case: We have reported 2 patients whose ectopic pregnancy had been managed conservatively and they had sustained pain for several months which needed surgery to resolve.
Conclusion: In the case of ectopic pregnancy, it is important for the clinician to select the patient meticulously and be aware of common and rare consequences of her treatment.

Abstract

Background: Hypospadias is one of the most common congenital abnormalities in the male which is characterized by altered development of urethra, foreskin and ventral surface of the penis. Androgen receptor gene plays a critical role in the development of the male genital system by mediating the androgens effects.
Objective: In present study, we looked for new variations in androgen receptor promoter and screened its exon 1 for five single nucleotide polymorphisms (SNP) in healthy and hypospadias Iranian men.
Materials and Methods: In our study, at first DNA was extracted from patients (n=100) and controls (n=100) blood samples. Desired fragments of promoter and exon 1 were amplified using polymerase chain reaction. The promoter region was sequenced for the new variation and exone 1 screened for five SNPs (rs139767835, rs78686797, rs62636528, rs62636529, rs145326748) using restriction fragment length polymorphism technique.
Results: The results showed a new single nucleotide variation (C→T) at -480 of two patients’ promoter region (2%). None of the mentioned SNPs were detected in patients and controls groups (0%).
Conclusion: This finding indicates that new single nucleotide polymorphism in androgen receptor promoter may have role in etiology of hypospadias and development of this anomaly.

Abstract

Background: Magnetized water has made many improvements in industry, agriculture and medicine. However its utilization in medicine still remains controversial.
Objective:  In this study we aimed to investigate the effects of magnetized water on height of epithelial cells in pre-implantation stage endometrium and fallopian tube and number of corpus lutea in female mice.
Materials and Methods:  Eighty female NRMI mice were recruited to this experimental study and randomly divided into two groups: the control group which drank normal water and the experimental (case) group which drank magnetized water for 2 weeks. Super-ovulation was induced in these mice and then they were mated with male mice as well. Samples of ovary, uterus and fallopian tube were obtained at the pre-implantation stage. Then, after preparation, the number of corpus lutea in each ovary was counted and the height of fallopian and endometrial epithelial cells was measured by light microscopy.
Results:  Data analysis showed a significant increase in the mean number of corpus lutea and the height of epithelial cells in fallopian tube comparing the case with the control group (p=0.01, p=0.002 respectively) whereas uterus epithelial cells of the case group showed insignificant increase in height, in compare with the control group (p=0.052).
Conclusion:  Our results suggest that magnetized water intake increases the number of corpus lutea and the height of fallopian tube epithelial cells. Further research is needed to determine whether this will increase in the success rate of fertility.
