Background: Various approaches have been used in the attempts to improve the quality of frozen–thawed mouse sperms. According to literatures, it seems that hyaluronic acid (HA) has an important role on the permeability and motility of sperms and their interaction with gametes.
Objective: For evaluation of HA supplementation on sperm characteristics and fertilization capability, we investigated the effect of different doses of HA on mouse sperm morphology, motility, vitality and fertilization capability after freezing and thawing.
Materials and Methods: The cauda epididymes was removed from 6 male mice with aseptic method. The sperm samples were frozen in 1.8 ml cryotubes with 18% raffinose and 3% skimmed milk containing cryo-protectant solution. HA at the concentration of 750, 1000 or 1250 µg/ml was supplemented to frozen-thawed sperms. Sperm motility was measured with microscope, and fertilization rate was evaluated after routine IVF by counting the fertilized oocytes. For sperm morphology, papaniclau staining was used while; Eosin B was used for the assessment of sperm viability rate.
Results: HA supplementation (750 µg/ml) improved motility parameters (p < 0.05) and increased the fertility rate (p < 0.05). The effect of 1,000 µg/ml HA was also positive on the sperms. But 1,250 µg/ml HA had negative effect on above mentioned characteristic. On the other hand, none of these doses had any effect on sperm morphology.
Conclusion: The dose of 750 µg/ml of HA has the greatest effect on the motility, vitality and fertility rate of sperms after cryopreservation.

Background: Spinal cord injury (SCI) occurs most often to young men at the peak of their reproductive health. Only 10% of SCI men can father children without medical assistance due to potential impairments in ejaculation and sperm quality.
Objective: The main objective of this experimental study was to evaluate the epididymal necrospermia- sperm death, after chronic SCI in rat.
Materials and Methods: Forty-five adult Wistar rats were divided into 3 groups of SCI, sham, and control. Following laminectomy, SCI was induced onto exposed dura matter (T10) of anesthetized rats. Sham group underwent laminectomy of T10 only; while, control rats were not exposed to any type of injury or medication. The spermatozoa from cauda epididymis were aspirated after 50 days for analysis of necrospermia with three assays of Eosin-Y staining, Hypo-osmotic swelling (HOS), and Hoechst 33258 fluorescent dye.
Results: The rate of necrospermia in SCI rats was significantly increased when compared with other groups (p<0.05). Also, the rates of necrspermia in SCI samples were similar with application of 3 assays (Eosin-Y: 46.11±9.41; HOS: 45.88±8.89; Hoechst: 46.76±9.31). Total necrospermia was not observed in any of the epididymal samples.
Conclusion: The results showed that chronic SCI is associated with high rate of epididymal necrospermia in mammals such as rats. It is, therefore, recommended that an effective laboratory technique, such as Hoechst 33258 should be used for separation of live and motile sperms from necrospermic ones for assisted reproduction program.

Background: Vitrification is assumed to be a promising method to cryopreserve human oocytes but still needs optimizing.
Objective: The aim of this study was to improve the single step and step-wise vitrification effects on maturing mouse GVBD oocytes by ethylene glycol (EG) in conventional straws.
Materials and Methods: Oocytes with compact cumulus cells were cultured for 3hr in TCM199 supplemented with 10% fetal bovine serum (FBS) in 5% CO2 in air. GVBD oocytes were randomly allocated into three groups. (1) Control (non-vitrified group), (2) exposed to single-step vitrification (contained of EG 20%+0.5M sucrose), (3) exposed to step-wise vitrification (2%, 5%, 10%, 20%EG +0.5M sucrose). In vitrification groups,oocytes were thawed and underwent additional 21 hr maturation. Viability of oocytes and maturation to MII stage were analyzed using inverted microscope and additionally by staining of propidium iodide and Hoechst 33342.
Results: All non-vitrified oocytes were viable after 24 hr; however, viability of vitrified samples in single-step group was significantly lower than that of the step-wise and control Groups. Also, the maturation rate in the step-wise group was significantly higher (p < 0.05) compared to single-step.
Conclusion: These results suggest that step-wise vitrification of  GVBD oocytes as compared to single step vitrification  was better in the rate of  survival and in vitro maturation of oocytes.

Background: Routine oocytes cryopreservation remained an elusive technique in the wide ranges of available assisted reproductive technologies. The microtubules of oocytes are vulnerable to cryoprotectants and thermal change during cryopreservation.
Objective: The effects of a vitrification protocol were investigated on the spindle and chromosome configurations of mice oocytes cryopreserved at the germinal vesicle stage.
Materials and Methods: Germinal vesicle with cumulus cells were transferred to vitrification solution which was composed of 30% (v/v) ethylene glycol, 18% Ficoll-70 and 0.3 M Sucrose either by single step or in step-wise way. Following vitrification and in vitro maturation (MII), the matured oocytes were immonostained for meiotic spindles and chromosomes, before visualization using fluorescent microscopy.
Results: A statistically significant increase was observed in the survival and maturation rate in step-wise vitrification (88.96% and 71.23% respectively) compared to single step vitrification (70.6% and 62.42% respectively) (p<0.05). Normal spindle morphology after vitrification-thawing in step-wise vitrification group (77.26%) was higher than single step vitrification group (64.24%) but lower than control group (94.75%) (p<0.05).
Conclusion: The results suggest that vitrification with step-wise procedure on mice germinal vesicle oocytes has positive effects on survival and maturation rate and normal spindle configuration compare with single step vitrification procedure.

Background: Diazinon is a widely used Organophosphate insecticide which is applied against plant pests. This compound has various side effects because it acts as an acetyl cholinesterase enzyme inhibitor.
Objective: The aim of present study was to investigate the effects of diazinon on pituitary–gonad axis and ovarian histological changes in rats.
Materials and Methods: In total 50 female wistar rats were divided into 5 groups of 10 including control sham and experimental groups I II and III which orally received 50 100 and 150 mg/kg/bw diazinon for 14 days respectively. Diazinon was administered orally and 24 hours after the last treatment blood samples were taken from the heart centrifuged and sera were evaluated for the concentrations of estrogen progesterone and gonadotropins via RIA method. In addition ovaries were removed fixed and studied with steriological methods.
Results: The results show no significant changes in body weight among various groups; while ovarian weight in experimental group III decreased significantly (p<0.05). Also, no significant changes in the levels of LH, FSH and estradiol hormones were observed. In contrast, the concentration of progesterone showed a significant decrease in all experimental groups compared with the control group. The results showed no significance difference in the mean number of primary, secondary and graffian  follicles but there was a significant decline in the mean number of corpus luteum in experimental group receiving 150 mg/kg diazinon (p<0.05 ) .
Conclusion: One can conclude that oral administration of diazinon could have adverse effect on progesterone hormone level as well as hazardous effects on ovarian tissues and reproductive processes.

Background: Cryopreservation and in vitro maturation (IVM) of oocyte is becoming an important technique in infertility treatment and fertility preservation. Also it has been proposed to establish a genetic resource bank for endangered or commercially important animal species.
Objective: The aim of this study was to evaluate viability, maturation and fertilization rate of mouse immature oocytes after single and stepwise vitrification procedure.
Materials and Methods: Oocytes were obtained from 4 weeks old female mice 48h after intraperitoneal injection of 7.5 IU pregnant mare serum gonadotropin (PMSG). Collected oocytes before vitrification were exposed to cryoprotectant, which was composed of 30% (v/v) ethylene glycol, 18% (w/v) Ficoll-70, and 0.3 M sucrose, either by single step or in a step-wise way. After vitrification and storage in liquid nitrogen, the oocytes were warmed and washed two times in medium TCM199 and then subjected to IVM, fertilization and subsequent development to blastocysts.
Results: The oocytes survival rates after vitrifying-warming (88.96%), maturation rate (73.23%), the capacity of fertilization (57.80%) and embryonic development to blastocyst (16.41%) in the step-wise exposure were significantly higher (p<0.001) compared with corresponding rate in the single step procedure.
Conclusion: The results suggest that vitrification with step-wise procedure has positive effects on maturation and developmental capacity of mice germinal vesicle oocytes in compare with single step vitrification procedure.

Background: Recently, the relevance of social interactions as determinants of behavioral intentions has been increasingly perceived, but there is a lack of knowledge on how and why it interacts with couples’ fertility intentions.
Objective: This qualitative study was conducted to explore the influence of social network on couples’ intention to have their first child in urban society of Mashhad, Iran in 2011.
Materials and Methods: In this exploratory qualitative study in-depth interviews were conducted with 24 participants including 14 fertile women, two parents, three husbands and five midwives and health care providers. The sample was selected purposively in urban health centers, homes and workplaces until data saturation was achieved. Data analysis was carried out adopting conventional content analysis approach through giving analytical codes and identification of categories using MAXqda software. Study rigor verified via prolonged engagement, validation of codes through member check and peer debriefing.
Results: Findings from data analysis demonstrated four major categories about social network’s influence on couples’ intention to have their first child including 1) perception of fertility relevant social network, 2) occurrence of various types of social influence 3) subjective judgment to the benefits of social network and its fitness to personal life, and 4) couples’ interaction with social network.
Conclusion: Managing the fertility behaviors need to include the consideration of personal social networks surrounding the couples. It is important to apply the study findings in providing family planning services and dissemination of appropriate fertility behaviors through community-based reproductive health care delivery system.

Background: The major aneuploidies that are diagnosed prenatally involve the autosomal chromosomes 13, 18, and 21, as well as sex chromosomes, X and Y. Because multiplex ligation-dependent probe amplification (MLPA) is rapid and non-invasive, it has replaced traditional culture methods for the screening and diagnosis of common aneuploidies in some countries.
Objective:  To evaluate the sensitivity and specificity of MLPA in a cross-sectional descriptive study for the detection of chromosomal aneuploidies in comparison to other methods.
Materials and Methods:  Genomic DNA was extracted from the peripheral blood samples of 10 normal controls and the amniotic fluid of 55 patients. Aneuploidies screening of chromosomes 13, 18, 21, X and Y were carried out using specific MLPA probe mixes (P095-A2). For comparison purposes, samples were also tested by Quantitative Fluorescent-PCR (QF-PCR) and routine chromosomal culture method.
Results:  Using this specific MLPA technique and data-analyzing software (Genemarker v1.85), one case was diagnosed with 45, X (e.g. Monosomy X or Turner’s Syndrome), and the remaining 54 cases revealed normal karyotypes. These results were concordant with routine chromosomal culture and QF-PCR findings.
Conclusion:  The experiment demonstrates that MLPA can provide a rapid and accurate clinical method for prenatal identification of common chromosomal aneuploidies with 100% sensitivity and 100% specificity.

Background: Acrylamide (AA) is an important industrial chemical primarily. AA is also found in carbohydrate-rich foods that are prepared at high temperatures, such as French fries and potato chips. It is demonstrated that AA is a carcinogen and reproductive toxin and has ability to induce sperm damage.
Objective: The aim of this study was to observe the effects of AA on sperm parameters and evaluation of sperm chromatin quality and testosterone hormone in mice.
Materials and Methods: Totally, 16 adult male mice were divided into two groups. Mice of group A fed on basal diet; group B received basal diet and AA (10 mg/kg, water solution) for 35 days. The right cauda epididymis was incised and then placed in Ham’s F10 culture media at 37oC for 15 min. Released spermatozoa were used to analyze count, motility, morphology and viability. To determine the sperm DNA integrity and chromatin condensation, the cytochemical techniques including Aniline blue, Acridine orange and Chromomycin A3 staining were used.
Results: AA-treated mice had poor parameters in comparison with control animals. In sperm chromatin assessments, except TB (p=0.16), significant differences were found in all of the tests between two groups. It was also seen a significant decrease in concentration of blood testosterone in AA-treated animals when compared to controls (p<0.001).
Conclusion: According to our results, AA can affect sperm parameters as well as sperm chromatin condensation and DNA integrity in mice. These abnormalities may be related to the reduction in blood testosterone.

Background: Saccharin is an artificial non-caloric sweetener that used to sweeten products such as drinks, candies, medicines, and toothpaste, but our bodies cannot metabolize it. Sodium saccharin is considered as an important factor in tumor promotion in male rats but not in humans.
Objective: The objective of this study was to investigate the effect of saccharin consumption on sperm parameters and apoptosis in adult mice.
Materials and Methods: Totally 14 adult male mice were divided into 2 groups. Group 1 served as control fed on basal diet and group 2 or experimental animals received distilled water containing saccharin (0.2% w/v) for 35 days. After that, the left cauda epididymis of each mouse was cut and placed in Ham’s F10. Swimmed-out spermatozoa were used to analyze count, motility, morphology (Pap-staining) and viability (eosin-Y staining). Sperm DNA integrity, as an indicator of apoptosis, was assessed by SCD (sperm chromatin dispersion) and terminal deoxynucleotidyl transferase (TUNEL) assay.
Results: Following saccharin consumption, we had a reduction in sperm motility with respect to control animals (p=0.000). In addition, the sperm count diminished (17.70±1.11 in controls vs. 12.80±2.79 in case group, p=0.003) and the rate of sperm normal morphology decreased from 77.00±6.40 in control animals into 63.85±6.81 in saccharin-treated mice (p=0.001). Also, we saw a statistically significant increase in rates of sperm DNA damage and apoptosis in experimental group when compared to control one (p=0.001, p=0.002 respectively).
Conclusion: Saccharin consumption may have negative effects on sperm parameters, and increases the rate of sperm DNA fragmentation and apoptosis in mice.

Background: The particles in the range of 1-100 nm are called nanoparticles. Gold nanoparticle is one of the most important metal nanoparticles with wide usage.
Objective: This study investigated the effects of gold nanoparticles on sperm parameters and chromatin structure in mice.
Materials and Methods: In this experimental study, 72 male bulb-c mice were divided into 9 groups including: 4 Sham groups (Sc 1-4), 4 experimental groups (Au 1-4), and 1 control group (C). Experimental groups received 40 and 200 µg/kg/day soluble gold (Au) nano-particles for 7 and 35 days, by intra peritoneal injection, respectively. Sham groups were treated with 1.2 mM sodium citrate solution with 40 and 200 µg/kg/day doses for same days and control group did not receive any materials. Motility and Morphology of spermatozoa were analyzed. Chromatin quality was also evaluated using AB (Aniline blue), TB (Toluidine blue) and CMA3 (Chromomycin A3) staining methods.
Results: The sperm analysis results showed that motility and morphology of sperm in experimental groups (especially in groups that have been treated for 35 days with nano-particles) had significant decrease in comparison with control group. TB, AB and CMA3 results showed a significant increase in abnormal spermatozoa from all Au-treated groups.
Conclusion: Gold nano-particles firstly can reduce the sperm parameters such as motility and normal morphology and secondly affect sperm chromatin remodeling and cause the increase instability of chromatin and also increase the rate of sperm DNA damage. These deleterious effects were more obvious in maximum dose and chronic phase.

Background: There are two methods for ventilation in gynecological laparoscopy: volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV).
Objective: To compare the lung mechanics, hemodynamic response and arterial blood gas analysis and gas exchange of two modes of VCV and PCV using laryngeal mask airway (LMA) at different time intervals.
Materials and Methods: Sixty infertile women referred for diagnostic laparoscopy, based on ventilation mode, were randomly divided into two groups of VCV (tidal volume: 10 ml/kg) and PCV. In the PCV group, ventilation was initiated with a peak airway pressure (tidal volume: 10 ml/kg, upper limit: 35 cm H2O). In both groups, the arterial blood samples were taken in several time intervals (5, 10 and 15 min after LMA insertion) for blood gas evaluation. Also the lung mechanics parameters were continuously monitored and were recorded at different time intervals.
Results: There were no significant differences for patient’s age, weight, height and BMI in two groups. The peak and plateau airway pressure were significantly higher in VCV group compared to PCV group 5 and 10 min after insertion of LMA. PaO2 was significantly higher after 10 and 15 min in VCV group compared to PCV group (p=0.005 and p=0.03, respectively). PaCO2 showed significant increase after 5 min in PCV group, but the differences were not significant after 10 and 15 min in two groups. The end tidal CO2 showed significant increase after 10 and 15 min in VCV compared to PCV group.
Conclusion: Both VCV and PCV seem to be suitable for gynecological laparoscopy. However, airway pressures are significantly lower in PCV compared to VCV.

Background: The outbreak of gestational diabetes has a significant increase during 14 recent years. This disease has complications for mother and her baby. Screening is an opportunity for preventing of gestational diabetes itchr('39')s complications.
Objective: The aim of this research was to determine the most important risk factors of gestational diabetes mellitus (GDM) in Iran according to the expertchr('39')s views by Group Analytical Hierarchy Process.
Materials and Methods: In this cross-sectional study, papers related to the prevalence and risk factors of GDM in Iran from 1992-2015 were reviewed. By studying texts and Upto Date databases, 10 risk factors of gestational diabetes were collected. Among these 10 items, the risk factors that have become significant based on studying literature in Iran were selected for analysis. GAHP questionnaire distributed among all experts.
Results: 8 risk factors of gestational diabetes were significant in Iran. The analysis of expertschr('39') views showed that "History of GDM or disorder in glucose tolerance in pregnancy" is the most important risk factor for developings GDM (40.7%). The second and third most important risk factors were "History of macrosomia (infant birth (weight > 4.1 Kg)" (20.2%) and" History of diabetes in first degree relatives " (10.7%).
Conclusion: Correct knowledge of prevalence of gestational diabetes and its risk factors is necessary for effective planning. SuggestSuggesting screening based on the importance of these risk factors can reduce the cost and stress in pregnant women. Also, it makes faster patient identifying faster.

Background: Clinical measurement of quality of life (QoL) for assessing reproductive problems should be considered as a standard investigation at the initial and continuing medical consultations with infertile people.
Objective: The purpose of this study was comprehensive testing the psychometric properties of the Iranian version of fertility quality of life (FertiQoL).
Materials and Methods: This cross-sectional study was conducted on300 women referred to infertility clinic. After linguistic validation, a semi-structured interview was conducted to assess face validity. Consequently exploratory factor analysis was performed to indicate the scale constructs. Discriminate validity was assessed using the known groups comparison. Convergent validity was evaluated by assessing the correlation between similar content on the 12-Item Short Form Health Survey (SF12), Hospital Anxiety and Depression Scale and FertiQol. In addition, reliability analysis was carried out with internal consistency.
Results: The reliability of the Iranian version of the FertiQoL was satisfactory in all dimensions (0.77-0.83). Six factors (emotional, mind/body, relational, social, environmental, and tolerability) were extracted from the results of exploratory factor analysis. Discrimination validity showed that FertiQoL can differentiate between female patients with differing duration of infertility and number of children. Moreover, the results of convergent validity showed a favorable correlation between the related dimensions of SF12 (0.43-0.68), Hospital Anxiety and Depression Scale (0.47-0.52) and FertiQoL.
Conclusion: The Iranian version of FertiQoL is valid and reliable for assessing infertility problems and the effects of treatment on QoL of infertile patients referred for diagnosis and treatment at infertility clinic.

Background: Generation of free radicals and oxidative stress are a major contributor to diabetes. These factors lead to the development of diabetic testicles disorders.
Objective: In this study, the protective effect of vitamin E on functional disorders associated with diabetes induced oxidative stress in male reproductive systems has been investigated.
Materials and Methods: Thirty-three adult male Mice were divided into control, diabetic, and untreated diabetic groups. Streptozotocin was used to induce diabetes. In the treated group, vitamin E was given to the Mice intraperitoneally for 30 days. Then, animals were anesthetized and sacrificed. Animal testicles were isolated and homogenized in phosphate buffer and used for measuring sperm count, motility and survival of sperm, MDA concentration and antioxidant capacity (TAC). Apoptosis was also performed with the TUNEL test.
Results: The results of reduction (12.03±98.11) TAC, MDA concentration (–28.5±2.58), sperm motility (unstable sperma= 86.4±7.48), sperm count (171.51), Sperm morphology (natural morphology= 49.69±31.93) and abnormal morphology (9.77±49.7) with increased oxidative damage. These changes were statistically significant in comparison with the control group for all variables other than MDA (p= 0.05). Treatment of vitamin E diabetic Mice improved the ability of antioxidants to prevent oxidativedamage in the testicles, restore the sperm movement, and increase the number of normal sperm as well as TAC. The level of apoptosis in the treated group has decreased compared to the untreated group.
Conclusion: Vitamin E protects the reproductive system against diabetes mellitus. Therefore, it was concluded that vitamin E may be a suitable agent for protecting the sperm and testicular parameters against undesirable effects of diabetes.

Background: Tamoxifen (TX) is widely used for the treatment of male factor and idiopathic infertility. It has been shown that TX induces sperm production and so improves male fertility.
Objective: This study evaluated the effects of different doses of TX on the sperm parameters and chromatin quality in mice.
Materials and Methods: In this research, 24 male NMRI mice were divided into three groups including group A: control animal receiving vehicle; group B: the group receiving basal diet and TX 0.4 mg/kg/day; and group C: the group receiving basal diet and TX 0.6 mg/kg/day for 35 days. Thereafter, epididymal spermatozoa were analyzed for standard parameters and nuclear chromatin quality using Aniline Blue (AB) and Toluidine Blue (TB) staining.
Results: The results indicated that although the TX did not affect the sperm count, motility, and viability parameters, it could elevate the percentage of sperm cells with abnormal morphology and abnormal chromatin at both doses. In addition, in comparison with the control mice, a significant elevation was observed in spermatozoa with residual histones (assessed by AB staining) at high doses of TX.
Conclusion: Our experimental data in mice suggested that the use of TX for treating male infertility might increase the rates of spermatozoa with abnormal chromatin in a dose-dependent manner.

Background: Concentrations of plasma lipids levels during pregnancy clearly increases. According to some studies, dyslipidemia is effective in the incidence of preeclampsia and insulin resistance.
Objective: This study aimed to examine the relationship between hyperlipidemia and maternal and neonatal outcomes in pregnant women.
Materials and Methods: This is a cross-sectional study which was conducted on two groups of pregnant women with hyperlipidemia and normal ones to assess maternal and neonatal outcomes. Maternal data including gestational age, motherchr('39')s age, body mass index, and maternal weight gain during pregnancy, gestational diabetes mellitus, preeclampsia, cholestasis, and delivery method. Also, birth weight and Apgar score were gathered as the neonatal outcomes.
Results: The results showed that the prevalence of abnormal lipid parameters increased with increasing gestational age. In pregnant women with dyslipidemia in combination with increased triglyceride, cholesterol and Low-density lipoprotein, and decreased High-density lipoprotein, the incidence rates of gestational diabetes (p< 0.001), preeclampsia (p< 0.001), cholestasis (p= 0.041), fetal growth retardation (p< 0.001), and macrosomia (p< 0.001) were statistically higher.
Conclusion: Dyslipidemia was associated with some adverse effects of pregnancy and harmful fetal outcomes. Therefore, it seems that adding laboratory assessment of lipid profiles before and during pregnancy can be effective in early diagnosis of dyslipidemia.
