Pages 192-198BackgroundThe mammalian ovary is controlled by a number of biological rhythms, which regulate the recruitment and release of mature oocytes. The main objective of this study was to investigate the role of cellular clock proteins during follicle maturation in the mouse estrous ovary.MethodsImmunohistochemical (IHC) studies were performed on ovaries from 50 estrous staged mice culled at two time points of 09:00 [day] and 01:00 [mid-point of the dark cycle]. Six antibodies were used to identify the expression of core cellular clock proteins (BMAL1, CLOCK, CRY1, CRY2, PER1 and PER2) within the ovary and four follicle stages, primordial, primary, antral and corpus lutea. IHC data was scored using the Allred protocol and significance determined by Mann-Whitney tests. Differences were considered significant at pResultsAll four follicle stages presented greater BMAL1 and CLOCK protein scores during the day and up regulation of CRY1-2 and PER1-2 at night. In primordial follicles, BMAL1 and CLOCK increases were significant (pConclusionThe ovary demonstrated a cellular clock response to the light: dark cycle and in addition, as the ovarian follicles mature changes in the positive and negative arms of both clock responsive proteins were observed.Keywords: Cellular clock, Ovarian follicles, Ovary

Pages 199-207BackgroundBone morphogenetic protein 15 (BMP15) is a growth factor derived from oocyte and is essential for in vivo ovarian follicular growth and in this study, its effects on the improvement of growth and development of follicles during in vitro culture of neonatal mouse ovaries was investigated.MethodsTwo week old mice were cultured for 7 days in the basic culture media with or without follicle stimulating hormone (FSH) and BMP15 as four experimental groups; FSH-/BMP15-, FSHﰓ࿗, FSH-/BMP15 and FSHﰓ࿗. The ovarian follicles at different developmental stages in paraffin embedding sections of cultured and non-cultured ovaries were counted and compared. The 17-β estradiol (E2) and progesterone (P4) levels were analyzed in collected culture media. The expression ratio of developmental genes (PCNA, BMPR-IB, BMPR-II, FSH-R, CYP17 and ZP3) to housekeeping gene (GAPDH) was analyzed by real time PCR (RT-PCR) in comparison with non-cultured control ovaries. The data was compared by independent t-test and one-way ANOVA (with Tukeys Post Hoc test). The pResultsThe percentage of antral follicles, ovarian size, concentration of E2 and P4 and the expression ratio of PCNA and ZP3 genes in the ovaries cultured in medium supplemented with BMP15 and FSH increased significantly in comparison with other cultured groups (pConclusionThis study demonstrated a favorable effect of BMP15 in combination with FSH on in vitro development of small size mouse follicles to antral stage.Keywords: Bone morphogenetic protein 15, Follicle stimulating hormone, Gene expression, Organ culture, Ovary

Pages 208-212BackgroundWhile multiple factors can contribute to male infertility, genetic factors, such as chromosomal disorders or Y-chromosome microdeletion, are responsible for about 10% of male infertility. Considering the role of Y-chromosome microdeletions in men with oligozoospermia who volunteer for in vitro fertilization (IVF), the prevalence of such microdeletions in each particular community needs to be exactly determined. Hence, the present study attempted to analyze the available literature on the frequency of chromosome microdeletion among Iranian infertile men.MethodsIn the first stage, a systematic search was performed on international and Iranian databases including PubMed, Scopus, Web of Science, IranMedex, MEDLIB, and Scientific Information Database in order to extract all relevant studies published until December 1, 2014.ResultsAccording to the literature review and meta-analysis process, Y chromosome microdeletions were present in about 12.1% (95% CI, 6.5-21.5) of Iranian infertile men with azoospermia and severe oligozoospermia.ConclusionBecause of the presence of Y-chromosome microdeletion in at least 12% of Iranian infertile men, it is necessary all the IVF centers, implement this Y-chromosome microdeletion screening tests in the work-up of male infertility.Keywords: Azoospermia, Microdeletions, Oligoastenospermia, STR markers, Y, Chromosome

Pages 213-220BackgroundBeing infertile comes as an overwhelming realization for couples trying to conceive. In consideration of rising rates of infertility worldwide, clinicians in India have also begun exploring this field for new possibilities, development and research. The purpose of this study was to estimate the proportion and predictors of infertility specific stress in males diagnosed with primary infertility.MethodsThis cross-sectional research was conducted in an assisted reproduction center, Manipal, India, on 300 infertile married males. The tools were "semi-structured questionnaire" compiled by the authors, "ICD-10 Classification of Mental and Behavioural Disorders (Clinical Descriptions and Diagnostic Guidelines) and" Psychological Evaluation Test for infertility. Multiple logistic regression analysis was carried out on data with p-value fixed as 0.05.ResultsThe presence of stress was reported in 72% of male participants. The predictors of stress were nature and severity of their infertility diagnosis, sperm defects, urological condition and experience of corrective surgery undergone for it. Psychological stress in men was also predicted by present and past history of significant psychiatric morbidity and coping difficulties associated with it.ConclusionThe stress is both a common experience and at times a clinical condition associated with deteriorating mental and physical health in men seeking fertility treatments. As a prerequisite, Indian fertility clinics need to treat stress as an identifiable condition and devise ways of addressing it at all stages of assisted conception and reproductive treatments.Keywords: Cross, sectional study, India, Infertility, Male, Morbidity, Psychological factors, Stress

Pages 221-229BackgroundInfertility as a crisis can both lead to negative reactions and stress in infertile couples and bring about positive reactions and growth, to which henceforth posttraumatic growth is referred. This study was conducted to model the relation between martial adjustment and posttraumatic growth through the mediation of religious coping strategies in infertile couples.MethodsThis correlation-based study was performed on 250 couples at the infertility center of Shariati hospital, Tehran, Iran, selected via convenience sampling. They answered to the Marital Adjustment Scale, the Posttraumatic Growth Inventory, and the Religious Coping Strategies Inventory. This study used Structural Equation Modeling.ResultsThe results showed significant positive relationships between marital adjustment and both positive religious coping strategies and posttraumatic growth. A significant positive relationship between positive religious coping strategies and posttraumatic growth was also detected. Positive religious coping strategies were observed to play a mediatory role between marital adjustment and posttraumatic growth. This was the case while attributing such a mediatory role to negative coping strategies was not possible.ConclusionBased on the results, this study can be seen as further evidence showing the necessity of focusing on the role of positive religious coping strategies in marital adjustment and posttraumatic growth in infertile couples.Keywords: Coping strategies, Infertile couple, Marital adjusment, Posttraumatic Growth, Religion

Pages 230-239BackgroundIran has the second highest rate of cesarean section in the world. the corresponding rate in the third metropolitan city of Iran, Isfahan, is even higher. This paper aimed to assess correlates and determinants of intention for cesarean section versus normal vaginal delivery (NVD) among pregnant women in Isfahan.MethodsA study was conducted among 400 pregnant women aged 18-38 years, with gestational age of 24-40 weeks who attended labor clinics of nine hospitals in Isfahan during June and July 2014. Probability proportional to size was used to estimate the number of cases required to be selected for each hospital. T-test, chi-square and logistic regression analysis were employed to analyze the data.ResultsMean age of women was 26.6±4.4 years. Multivariate analysis identified selected factors as determinants of intention for CS. These were "the role of physician" (OR=1.33, pConclusionChoosing cesarean section voluntarily is a multifaceted decision which is shaped by various factors; hence, comprehensive interventions are suggested to discourage voluntary cesarean section. These interventions need to encompass changes in physicians role, social norms, body image and correcting misperceptions among women towards CS and NVD during prenatal courses.Keywords: Cesarean section, Determinants, Iran, Vaginal delivery

Pages 240-242BackgroundThyroid autoimmunity may be linked to infertility, in both thyrotropin (TSH)-dependent and TSH-independent fashion. The aim of the present study was to assess this presumed reciprocal relationship of thyroid autoimmunity and pregnancy.MethodsTSH and antithyroid peroxidase autoantibodies (anti-TPO) were evaluated retrospectively over an eight-year period in 444 Greek women who had previously none or at least one pregnancy (>28 weeks). Statistics were done with analysis of covariance (ANCOVA) and the Chi square test.ResultsThyrotropin was higher in women with one pregnancy and lower in those with two or more pregnancies compared to women with no pregnancies. Furthermore, significantly more women with no pregnancies were anti-TPO (), compared to women with one or those with at least two pregnancies.ConclusionBecause pregnancy might contribute to the development of thyroid autoimmunity, women should be monitored for development of thyroid autoimmunity long after their pregnancies, even after an uneventful first conception, pregnancy and delivery of a live infant.Keywords: Fertility, Pregnancy, Thyroid, Thyrotropin

Pages 243-246BackgroundGigantomastia is a breast disorder marked by exaggerated rapid growth of the breasts, generally bilaterally. Since this disorder is very rare and has been reported only in sparse case reports its etiology has yet to be fully established. Treatment is aimed at improving the clinical and psychological symptoms and reducing the treatment side effects; however, the best therapeutic option varies from case to case.Case PresentationThe present report described a case of gestational gigantomastia in a 30-year-old woman, gravida 2, parity 1, 17 week pregnant admitted to Pars Hospital, Tehran, Iran, on may 2014. The patient was admitted to hospital at week 17 of pregnancy, although her breasts initially had begun to enlarge from the first trimester. The patient developed hypercalcemia in her 32nd week of pregnancy. The present report followed this patient from diagnosis until the completion of treatment.ConclusionAlthough gestational gigantomastia is a rare condition, its timely prognosis and careful examination of some conditions like hyperprolactinemia and hypercalcemia is essential in successful management of this condition.Keywords: Breast, Diagnosis, Gestational age, Gigantomastia, Hypercalcemia, Iran, Therapeutics

Pages 247-249Background95% of Tuberculosis (TB) of the female genital tract (FGT) is located in tissues other than the cervix. A rare case of primary TB of the cervix which was diagnosed coincidently in a patient of endometrioma was reported in this study.Case PresentationA 34 year old nullipara, a diagnosed case of endometrioma had a small cervical growth. Pap smear and biopsy was taken and sent for histopathological examination. Her histopathological examination revealed multiple epitheloid cell granuloma and langerhans type giant cell caeseation. Ziehl neelsen staining was positive for acid fast bacilli (AFB). The patient was started on antituberculosis under directly observed therapy along with oral contraceptive pills. Patient was on regular follow-up and clinically she was doing well.ConclusionAlthough cervical tuberculosis is very rare but for an abnormal looking cervix, cervical tuberculosis should be considered in the differential diagnosis in woman of all the age groups especially in areas where tuberculosis is rampant since these cases are potentially curable with medical therapy. Many of these patients are in reproductive age group. In young women, early diagnosis prevents further damage in reproductive tract and can improve their reproductive potential.Keywords: Cervix, Genital tuberculosis, Tuberculosis
