Abstract
Background: In vitro maturation (IVM) of oocytes is a promising technique to reduce the costs and avert the side-effects of gonadotropin stimulation for in vitro fertilization (IVF). The pregnancy rates from oocytes matured in vitro are much lower than those of in vivo stimulation cycles, indicating that optimization of IVM remains a challenge. Objective: In this study, we investigated the effect of cumulus cells on maturation and fertilization rate of immature oocytes (Germinal vesicle). Materials and Methods: Germinal vesicle (GV) oocytes were recovered from 6-8 weeks old Balb C female mice 48hr after injection of 10 IU pregnant mare serum gonadotropin (PMSG). Collected oocytes were divided into two groups. Group A: GV oocytes without cumulus (denuded oocyte). Group B: GV oocytes with cumulus cells (cumulus-oocyte complex). The oocytes in both groups were cultured in TCM-199 medium in a humidified atmosphere of 5% CO2 in air at 37�C. The maturation, fertilization and developmental rates were recorded after 24hr. Results: Maturation, fertilization and developmental rates in denuded oocytes (DO) were 65.1%, 68.02%, 78.63% respectively, and in cumulus-oocyte complex (COC) were 78.20%, 85.57% and 85.05%, respectively. The maturation, fertilization and developmental rates of COC were significantly higher than those of DO (p<0.05). Conclusion: The results show that cumulus cells have beneficial effects on maturation, fertilization and cleavage rates of mice oocytes.

Abstract
Background: The ability of the ovary to respond to exogenous gonadotrophin stimulation and development of several follicles is essential in assisted reproductive technology. Neither age and regularity of menses nor follicular phase FSH and estradiol concentrations are reliable predictors of ovarian response. Day 3 serum inhibin-B level, during induction ovulation, has been proposed as a predictor of ovarian response.
Objective: To determine day 3 serum inhibin-B as a predictor of ovarian response to induction ovulation in IVF/ ICSI cycles.
Materials and Methods: Seventy one infertile patients under 40 years old were enrolled in this study. All women have both ovaries, basal FSH level under 15 mIU/ml, and no evidence of endocrine disorders. Day 3 FSH, estradiol, inbibin-B concentrations and ovarian volume were measured before treatment. All patients underwent standard long GnRH agonist protocol. The number of oocytes retrieved, fertilization rate, clinical pregnancy rate, days of stimulation and number of HMG ampoules were determined. The patients were divided into two groups, normal responders and poor responders (number of oocytes retrived <4).
Results: The mean inhibin-B level in normal responders was 166.9 141 pg/ ml versus 115.8 87 pg/ml in poor responders, which the difference was not statistically significant (p=0.24). We could not find a cut off between normal and poor responders.
Conclusion: The use of day 3 inhibin-B level as a predictive marker of ovarian response in IVF/ICSI cycles is not reliable.

Abstract
Background: It is established that sperm DNA integrity is essential in fertilization and normal embryo and fetal development. Routine semen analysis gives an approximate evaluation of the functional competence of spermatozoa, but does not always reflect the quality of sperm DNA. Therefore, the evaluation of sperm DNA integrity, in addition to routine sperm parameters, could add further information on the quality of spermatozoa and reproductive potential of males.
Objective: The objective of this study was to determine the levels of sperm DNA damage in fertile and infertile males and its correlation with semen parameters.
Materials and Methods: Semen samples were collected from 45 infertile men selected from couples attending the infertility clinic with a history of infertility of ≥1 years and 75 healthy volunteers of proven fertility (initiated a successful pregnancy) served as the control group. After routine sperm analysis, DNA damage was determined using single cell gel electrophoresis (comet) assay method.
Results: The mean of DNA damage (comet value) in the sperms of infertile males was significantly higher than that of fertile males (12.9±7.59 vs. 48.77±24.42, p<0.001). A significant negative correlation was observed between DNA damage and sperm motility in fertile group (p<0.02, R=-0.263). In infertile males, significant negative correlations were observed between DNA damage with sperm motility (p<0.002, R=-0.45) and morphology (p<0.03, R=-0.317). There was no significant correlation between sperm concentration and sperm DNA damage in both groups.
Conclusion: These results indicate that sperm DNA damages in infertile males is significantly higher than fertile males and sperms with abnormal morphology and low levels of motility has more abnormal DNA damages than motile and normal sperms.

Abstract
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.

Abstract
Background: Mammalian oocytes are exposed to a mixture of many different growth factors and cytokines which provides an optimized microenvironment for oocyte maturation. In the lack of this natural microenvironment in vitro the quality of oocyte and embryos appears to be suboptimal. Objective: This study was undertaken to investigate the effects of EGF and LIF on in vitro maturation fertilization and cleavage rates in mouse oocytes. Materials and Methods: The GV oocytes were collected from female NMRI mice and randomly divided into control and 3 treatment groups. Oocytes in treatment groups were cultured in the maturation medium supplemented with 50 ng/ml rhLIF (Treatment 1) 10ng/ml EGF (Treatment 2) and 50 ng/ml LIF+ 10ng/ml EGF (Treatment 3) for 24 hours at 37°C in humidified 5% CO2 in air. The matured oocytes were fertilized in vitro and cultured for 96 hours. Finally the developmental rates were assessed and embryos were stained using Hoechst 33258.
Results: There was a higher maturation rate in treatment groups compared to the control group. There was not any significant difference in the rate of fertilization among the groups. The rates of cleavage (79.1%) and blastocyst formation (62.2%) were significantly higher in LIF + EGF group comparing to the other groups. The rates of hatching in groups treatment 1 (35.2%) and 3(41%) was significantly higher comparing to the other groups. Also the mean of total cell number in treatment groups significantly was higher than control (p< 0.05).
Conclusion: The findings of this study suggest a beneficial effect of LIF and EGF on mouse oocyte maturation and cleavage rates.

Abstract
Background: For infertile women aged over 35 years, failure of the ZP (zona pellucida) to rupture is believed to be associated with a decreased implantation rate in in vitro fertilization (IVF) or intra cytoplasmic sperm injection (ICSI).
Objective: In this research, laser assisted hatching (LAH) was offered to patients with advanced maternal age to evaluate a possible benefit.
Materials and Methods: Nine hundred thirty two cycles of IVF/ICSI in females were analyzed. Women included in this study were allocated in 4 groups. In group I and II, embryos were cultured and transferred with and without LAH in women aged ≤35, whereas embryos of group III and IV were examined with and without LAH in women aged ≥ 35. Laser manipulations were performed using a suturn-Tm3 system using 2-3 pulses of 0.8 millisecond with 400 voltage duration. The size of the hole made in the zona was measured to be 5-10 µm, depending on the zona thickness of each individual embryo.
Results: The performance of LAH significantly increased clinical pregnancy rates in all patients. In group I and II, the chemical (50.99% and 31.61% respectively), clinical (50% and 30.69% respectively) and multiple pregnancies (22.27% and 5.94% respectively) significantly differ between these groups. In the patients with advanced female age ≥35 the performance of LAH significantly increased chemical (30.12%) and clinical pregnancy (27.71%) rates compared to whom without LAH (18.96% and 16.37% respectively).
Conclusion: Our data demonstrate in the patients who were less than 35 years old, multiple pregnancy rates were significantly increased compared to other groups who aged over 35 years old. In addition benefit of LAH in improving pregnancy rates after IVF or ICSI in women of advanced age (≥35) was shown.

Abstract
Background: Obesity is an independent risk factor of preeclampsia with unknown mechanism and hyperlipidemia might be a probable case of it. Objective: The objective of this study was to determine the role of hyper-triglyceridemi in association with high prepregnancy body mass index and the risk of preeclampsia.
Materials and Methods: The authors conducted this case-control study of 42 preeclamptic and 41 normotensive overweight pregnant women. The two groups were comparable with respect to age, gestational age, and body mass index. Blood samples were collected at the time of diagnosis of preeclampsia, after 14 hour fasting to determine plasma lipid concentrations. Enzymatic photometric tests were used to determine lipid profile. Data was analyzed with independent “t-test”, Chi-square and one-way ANOVA and post HOC Tukey HSD test. The statistical significance was set at 0.05 levels. Results: In the subjects with preeclampsia, serum triglyceride and total cholesterol levels were significantly increased and plasma HDL-cholesterol concentrations were decreased compared with the controls, (p<0.05), but plasma LDL cholesterol levels didn’t differ between the two groups. Women who developed severe preeclampsia had higher concentrations of TG and cholesterol and lower levels of HDL compared to noromotensive group. Mean TG: 375.16 vs. 202.85, p<0.001, Mean cholesterol: 245.64 vs. 214.32, p=0.04, Mean HDL: 40.80 vs. 48.95, p=0.03).
Conclusion: We noted that dyslipidemia, particularly hypertriglyceridemia was highly correlated with prepregnancy high BMI in preeclamptic women. These findings continue to support a role for dyslipidemia in BMI related preeclampsia.

Abstract
Background: Idiopathic thrombocytopenic purpura (ITP) is a disease that commonly affects women of reproductive age and is associated with maternal and fetal complications.
Objective: The aim of the present study was to report the perinatal outcome in pregnant women with ITP. Materials and Methods: Twenty one pregnant women with ITP admitted in a teaching hospital in Tehran, from October 2008 to February 2010, were enrolled in this prospective historical cohort study; course and perinatal outcome of pregnancies were studied.
Results: Seven (33.3%) cases had been diagnosed before pregnancy, while the other fourteen (66.7%) were diagnosed during pregnancy. During hospitalization, thirteen (62%) patients required treatment, eight (61.5%) of them with steroids, two (15.3%) received intravenous immunoglobulin (IVIG), and three (23%) were treated with steroids and IVIG. Three babies were delivered vaginally (14.3%), seventeen (81%) through cesarean section and one patient aborted her fetus. Nine mothers (42.9%) had platelet counts <50000/ml at the time of delivery; but postpartum hemorrhage occurred in 4 (19%) women and one women received platelet transfusion during cesarean section. Six (28.6%) women developed gestational diabetes. Pregnancy was complicated by preeclampsia in one woman and by abruptio placenta in another. One pregnancy terminated in intrauterine fetal death. Seventeen infants (89.5%) had normal platelet counts, and two (10.5%) had moderate thrombocytopenia. No infant showed signs of hemorrhage, but 2 neonates (10.5%) were diagnosed with intrauterine growth restriction.
Conclusion: Rate of gestational diabetes in pregnant women with ITP is higher than the general population. Rate of gestinational diabetes is 3-5% and postpartum hemorrhage is 5-7% in general. Postpartum hemorrhage is common in these women. Severe thrombocytopenia and bleeding in the newborns are uncommon.

Abstract
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.

Abstract
Background: Indisputable population exposure to widespread electromagnetic fields, has grown concerns over the probable health effects of these fields. Objective: The present study was aimed to examine the possible effects of 50 Hz extremely low frequency electromagnetic field (ELF-EMF) exposure on the number and quality of mice blastocysts.
Materials and Methods: In present study, 66 NMRI pregnant females divided into two treated and non-treated groups. The treated group exposed to ELF-EMF (50 Hz and 6×10-3 T). Subsequently, embryos were collected by flushing the uterine horn and Fallopian tubes on the day 3 of gestation. Number of trophoectoderm (TE) and Inner Cell Mass (ICM) cells in blastocysts were determined after differential nuclei staining using a modified method. Furthermore, number of all flushed blastocysts calculated in each group.
Results: There was no significant difference in mean number of blastocysts in treated (6.64±1.34) and none treated (8.22±1.59) groups. In treated group, there were significant decreased in total cell number of blastocysts (p=0.000), number of ICM cells (p=0.000), and number of TE cells (p=0.001) whereas the ratio of ICM/TE cells increased (p=0.002).
Conclusion: The data indicate that ELF-EMF is able to affect cellular composition of blastocysts, but it can't omit total volume of blastocysts.

Abstract
Background: Vitamin D deficiency during pregnancy is associated with some adverse pregnancy outcomes but its relationship with fetal growth is unknown.
Objective: We compared the 25-hydroxy vitamin D levels between mothers and their small for gestational age (SGA) newborns with mothers and their appropriate for gestational age (AGA) newborns.
Materials and Methods: The study population included pregnant women that referred to Afzalipour Hospital in Kerman from 2012 to 2013. The case and control group consisted of 40 pregnant mothers with SGA and AGA newborns, respectively. The maternal and infants 25-hydroxy vitamin D levels were measured in the two groups.
Results: 25-hydroxy vitamin D deficiency (<20 ng/ml) was statistically higher in women with SGA newborns in comparison to women with AGA newborns (p=0.003).Vitamin D deficiency was higher among the SGA newborns in comparison to AGA newborns (25% vs. 17.5%), although this finding was not statistically meaningful (p=0.379). The relationship of vitamin D deficiency levels between mothers and infants in both the SGA group and the AGA group was significant.
Conclusion: Our study reveals a high prevalence of vitamin D deficiency in women with SGA infants in comparison to women with AGA children. In addition, maternal vitamin D deficiency is associated with its deficiency in newborns.

Abstract
Background: Oxidative stress in reproductive system leads to sperm DNA damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. Antioxidants such as carotenoids function against free radical damages. Objective : The aim of this study was to determine the levels of lycopene, beta-carotene and retinol in serum and their relationship with sperm DNA damage and lipid peroxidation in infertile and normospermic males. Materials and Methods: Sixty two infertile men and 71 normospermic men participated in this study. Blood and semen samples were collected from all subjects. Sperm DNA damage was measured using TUNEL method. Carotenoids, retinol, and malonedildehyde in serum were also determined. Results: DNA fragmentation was higher in infertile group comparing to control group. Serum levels of lycopene, beta-carotene and, vitamin A in infertile men were significantly lower than normospermic men (p< 0.001, =0.005, and =0.003 respectively). While serum MDA was not significantly different between two groups, MDA in seminal plasma of infertile men was significantly higher than control group (p< 0.001). Conclusion: We concluded that lycopene, beta-carotene, and retinol can reduce sperm DNA fragmentation and lipid peroxidation through their antioxidant effect. Therefore the DNA fragmentation assay and determination of antioxidants factors such as lycopene, beta-carotene and retinol, along with sperm analysis can be useful in diagnosis and treatment of men with idiopathic infertility.

Abstract
Background: After improvements in various cancer treatments, life expectancy has been raised, but success in treatment causes loss of fertility in many of the survived young men. Cryopreservation of immature testicular tissues or cells introduced as the only way to preserve fertility. However, freezing has some harmful effects. Melatonin, a pineal gland hormone, has receptors in reproductive systems of different species. It is assumed that melatonin has free radical scavenger properties.
Objective: The aim of this study was to evaluate the effects of melatonin on the cryopreserved testicular cells in mouse.
Materials and Methods: Cells from 7- 10 days old NMRI mice testes were isolated using two step enzymatic digestion. The testicular cells were divided into two groups randomly and cryopreserved in two different freezing media with and without the addition of 100 µm melatonin. Finally, apoptosis of the cells was assayed by flow cytometry. Also, lactate dehydrogenase activity test was performed to assess the cytotoxicity.
Results: The results of lactate dehydrogenase showed the nearly cytotoxic effect of melatonin. The results of flow cytometry showed increase in apoptosis in the cryopreserved cells in the media containing melatonin compared to the control group.
Conclusion: The present study shows that melatonin has an apoptotic effect on cryopreserved mouse testicular cells.

Abstract
Background: Sexual problems have different effects on the life of people by influencing their interpersonal and marital relationships and satisfaction. Relationship between sexual dysfunctions and infertility can be mutual. Sexual dysfunction may cause difficulty conceiving but also attempts to conceive, may cause sexual dysfunction.
Objective: This paper compares sexual dysfunction in fertile and infertile women.
Materials and Methods: In this cross-sectional study, 110 infertile couples referring to Montasarieh Infertility Clinic and 110 fertile couples referring to five healthcare centers in Mashhad were selected by class cluster sampling method. Data collection tools included demographic questionnaire and Glombok-Rust Inventory of Sexual Satisfaction. Data were analyzed through descriptive and analytical statistical methods by SPSS.
Results: There was no significant difference in total score of sexual problems and other dimensions of sexual problems (except infrequency) in fertile 28.9 (15.5) and infertile 29.0 (15.4) women. Fertile women had more infrequency than infertile women (p=0.002).
Conclusion: There was no significant difference between fertile and infertile women in terms of sexual problems. Paying attention to sexual aspects of infertility and presence of programs for training of sexual skills seems necessary for couples.

Abstract
Background: Neuroendocine carcinoma of the gynecologic tract is rare and poses a significant clinical challenge because of tumor heterogeneity and lack of standardized guidelines for treatment. Ovotestis refers to the histology of a gonad that contains both ovarian follicles and testicular tubular elements. Ovotesticular disorder of sexual development occurs in fewer than 10% of all disorders of sexual development. Gonadal tumors with malignant potential occur in 2.6% of all cases of ovotesticular disorder of sexual development.
Case: Here we represent a 77-year-old woman with primary amenorrhea, infertility and 10cm solid mass in left adnex with 46 XY in karyotype with ovotestis neuroendocrine neoplasm in pathology report which was treated with a multi-modality manner including surgery and chemotherapy but she came back with pulmonary metastasis after 2 cycles of chemotherapy. For women who present with a stage 1 primary ovarian neuroendocrine tumor the prognosis is excellent with greater than 90% survival. Neuroendocrine tumor of the ovary represents 3 % of all neuroendocrine tumors. The prevalence of ovotestis is 1/20000 births. For women with more advanced disease, the prognosis is poor. Neuroendocrine carcinoma of the ovary is a rare and aggressive tumor commonly associated with other surface epithelial and germ cell neoplasms. The prevalence of ovotestis is 1/20000 births and gonadal malignancies are the most reported neoplasm affected the ovotestis. Here we report a case of ovotestis which is presented with neuroendocrine carcinoma and poor prognosis.
Conclusion: Neuroendocrine carcinoma of the ovary is a rare and aggressive tumor commonly associated with other surface epithelial and germ cell neoplasms. The prevalence of ovotestis is rare and gonadal malignancies are the most reported neoplasm affected the ovotestis.

Abstract
Background: Testicular damage due to spermatic cord torsion may lead toinfertility. It is probably because of changes in oxidative stress factors such asmalondialdehyde.
Objective: To investigate the protective effect of melatonin (MLT), as anantioxidant, on testicular damage induced by acute unilateral spermatic cord torsionand detorsion (T/D) in rats.
Materials and Methods: In this experimental study, 48 adult male Wistar rats wererandomly divided into three groups (8 rats/group): sham group underwent rightscrotal surgery only., the T/D group underwent right testicular torsion (for 1 hr) anddetorsion, and the melatonin group underwent right testicular torsion, received 25μg/kg melatonin intraperitoneally immediately after surgery of T/D. Then thehistological parameters and malondialdehyde (MDA) changes were evaluated.
Results: Torsion and detorsion decreased the diameter of the tubules significantlycompared to controls (p=0.003). Melatonin could increase the diameter, but it wasnot significant (p=0.26). The heights of the epithelium were constant in sham, T/D,and melatonin groups without any significant difference between groups (p=0.98).Based on Johnsen’s score, spermatogenesis was normal in the sham group. Thetorsion significantly injured all lineage cells (p<0.001). There was no any spermatidor sperm in the seminiferous tubules. Melatonin improved the spermatogenesissignificantly (p=0.02), but could not improve MDA level significantly (p=0.99).
Conclusion: Severe degenerative changes of testis were induced by acute unilateralspermatic cord torsion and detorsion in rats, but it had no effect on MDA level.

Abstract
Background: Psychological interventions such as counseling for infertile patients seem to increase pregnancy rate.
Objective: The aim of this systematic review and meta-analysis was to examine if counseling improves pregnancy rate among infertile patients. Thus, randomized controlled trials investigating the effect of counseling on pregnancy rate in infertile patients undergoing ART were pooled in a meta-analysis.
Materials and Methods: The databases of PubMed, Scopus, Cochrane, Google Scholar, and Persian databases including SID, Iran Medex, and Magiran were searched from 1997 to July 2016 to identify relevant articles. Included studies were trials on infertile patients (women or couples) receiving counseling independent of actual medical treatment. The outcome measure was pregnancy rate. Out of 620 relevant published trials, a total of nine RCTs were ultimately reviewed systematically and included in a meta-analysis to measure the efficacy of counseling on pregnancy rate. Odds ratio and Risk difference were calculated for pregnancy rate. All statistical analyses were done by Comprehensive Meta-analysis Version 2.
Results: Nine RCTs involving 1079 infertile women/couples were included in the study. The findings from RCTs indicated significant effect of counseling on pregnancy rate so that there was a positive impact of counseling on pregnancy rate (OR= 3.852; 95% CI: 2.492-5.956; p=0.00) and (RD= 0.282; 95%; CI: 0.208-0.355; p=0.00).
Conclusion: Counseling was found to improve patients’ chances of becoming pregnant. So counseling represents an attractive treatment option, in particular, for infertile patients who are not receiving medical treatments.

Abstract
Background: Waiting period of fertility treatment is stressful, therefore it is necessary to use effective coping strategies to cope with waiting period of intrauterine insemination (IUI) treatment.
Objective: The aim of this study was comparing the effect of the positive reappraisal coping intervention (PRCI) with the problem-solving skills training (PSS) on the coping strategies of IUI waiting period, in infertile women referred to Milad Infertility Center in Mashhad.
Materials and Methods: In this randomized clinical trial, 108 women were evaluated into three groups. The control group received the routine care, but in PRCI group, two training sessions were held and they were asked to review the coping thoughts cards and fill out the daily monitoring forms during the waiting period, and in PSS group problem-solving skill were taught during 3 sessions. The coping strategies were compared between three groups on the 10th day of IUI waiting period.
Results: Results showed that the mean score for problem-focused were significantly different between the control (28.54±9.70), PSS (33.71±9.31), and PRCI (30.74±10.96) (p=0.025) groups. There were significant differences between the PSS group and others groups, and mean emotion-focused were significantly different between the control (32.09±11.65), PSS (29.20±9.88), and PRCI (28.74±7.96) (p=0.036) groups. There were significant differences between the PRCI and the control group (p=0.047).
Conclusion: PSS was more effective to increase problem-focused coping strategies than PRCI, therefore it is recommended that this intervention should be used in infertility treatment centers.

Abstract
Background: Neopterin is a significant and sensitive marker in estimating the activity of cellular immune system. Oxidative stress plays a role in the etiology of male infertility. Increased reactive oxygen species is accompanied with increase in neopterin level. Hence neopterin may be involved in male infertility.
Objective: The objective of this case-control study was to determine neopterin level in idiopathic infertile and normospermic men; furthermore, to identify its relationship with oxidative stress markers including total oxidant, malondialdehyde, sperm DNA fragmentation, and total antioxidant capacity of seminal plasma.
Materials and Methods: Forty seven infertile and forty three normospermic males were selected according to WHO criteria. Their semen and blood samples were taken; subsequently, the levels of neopterin, total oxidant, total antioxidant, malondialdehyde, and sperm DNA fragmentation were measured.
Results: The levels of neopterin, total oxidant, and malondialdehyde in seminal plasma of infertile males were significantly higher than those of normospermic group (p=0.038, 0.018, and 0.028, respectively). Furthermore, sperm DNA fragmentation in infertile men was higher than that of control group (p<0.001). Moreover, total antioxidant capacity of seminal plasma in infertile males was significantly lower than that of normospermic subjects (p=0.002). No significant difference was observed in serum neopterin, total oxidant, and malondialdehyde between the infertile and normospermic groups.
Conclusion: The significant inverse correlation between seminal plasma neopterin and total antioxidant in the infertile males supports a possible role of neopterin in male infertility. Neopterin can be suggested as a marker in monitoring and diagnosis of idiopathic male infertility.
