MicroRNAs (miRNAs) are small non-coding single stranded RNA molecules that are physiologically produced in eukaryotic cells to regulate or mostly down-regulate genes by pairing with their complementary base-sequence in related mRNA molecules in the cytoplasm. It has been reported that other than its function in many physiological cell processes, dysregulation of miRNAs plays a role in the development of many diseases. In this short review, the association between miRNAs and some male reproductive disorders is surveyed. Male factor Infertility is a devastating problem from which a notable percentage of couples suffer. However, the molecular mechanism of many infertility disorders has not been clearly elucidated. Since miRNAs have an important role in numerous biological cell processes and cellular dysfunctions, it is of interest to review the related literature on the role of miRNAs in the male reproductive organs. Aberrant expression of specific miRNAs is associated with certain male reproductive dysfunctions. For this reason, assessment of expression of such miRNAs may serve as a suitable molecular biomarker for diagnosis of those male infertility disorders. The presence of a single nucleotide polymorphism (SNP) at the miRNAs’ binding site in its targeted mRNA has been reported to have an association with idiopathic male infertility. Also, a relation with male infertility has been shown with SNP in the genes of the factors necessary for miRNA biogenesis. Therefore, focusing on the role of miRNAs in male reproductive disorders can further elucidate the molecular mechanisms of male infertility and generate the potential for locating efficient biomarkers and therapeutic agents for these disorders.

Background: Small intrauterine lesions such as septum, adhesion, polyp, and submucous myoma may be of greater significance in causing implantation failure, poor reproductive performance and abnormal uterine bleeding. We studied effectiveness of therapeutic intervention through operative hysteroscopy in improvement of pregnancy outcome and cessation of abnormal uterine bleeding (AUB) in women with pregnancy and fertility problems. Materials and Methods: This prospective cohort study was performed between 2003- 2009 on 65 patients with primary or secondary infertility, recurrent abortion and structural uterine lesions reported in sonography or hysterosalpingography. After hysteroscopic metroplasty, myomectomy, adhesiolysis and polypectomy under laparoscopic guide, we evaluated reproductive outcome, early and late complications, one year after surgery. Results: Among all patients with recurrent abortion, 6 patients (75%) complete their pregnancy successfully. Our results showed that pregnancy rate after metroplasty was 58%. Reproductive outcome was poor after myomectomy and adhesiolysis. Abnormal uterine bleeding was improved in 62% of patients. Conclusion: Structural uterine lesions has been assumed to cause infertility, while several studies have shown very poor reproductive performance with high miscarriage and low term delivery rates when malformation is not treated. We show improvement in conceptional outcome and in patient’s chief complaints after hysteroscopy surgery of these anomalies.

Background: The association between blood types and ovarian reserve is investigated in this study. Materials and Methods: As an index of ovarian reserve, women with a follicle stimulating hormone (FSH) level of ≥10 mIU/ml in the early follicular phase were designated as having diminished ovarian reserve. In this prospective study, early follicular phase serum FSH and estradiol levels and blood types were evaluated in 500 patients who were admitted to the Infertility Department of Ministry of Health Etlik Zübeyde Hanım Women’s Health Training and Research Hospital between January 2012 and June 2012. Women with serum FSH level <10 mIU/ml formed group I, and women with serum FSH ≥10 mIU/ml formed group II. The prevalence of blood types in each group and their association with ovarian reserve were analyzed. Results: Out of 500 patients, 438 women were in group I, while 62 women were in group II. There was no statistically significant difference among the two groups in terms of blood group proportions (p=0.69), this did not change after age adjustment (p=0.77). The presence of A antigen (in A and AB blood type) (p=0.91), the blood type O (p=0.70), and the blood type B (p=0.51) were not statistically related to ovarian reserve after age adjustment. There was also no statistically significant correlation between rhesus factor and ovarian reserve after age adjustment (p=0.83). The only factor that affected ovarian reserve was age of patients (p=0.006). Conclusion: Blood groups do not constitute a risk or protective factor for ovarian reserve. Therefore, blood groups do not have any predictive value in evaluating ovarian reserve.

Background: To determine the correlates and the prevalence of infertility in a group of women. Materials and Methods: This cross-sectional study was carried out on 570 subjects aged 18-49 years in a town of western Turkey between July and August 2012. Women who have inability to become pregnant despite regular sexual intercourse during the last year were considered to be infertile. UCLA Loneliness Scale was used to assess the severity of loneliness. The data were analyzed by Kruskal-Wallis, Mann Whitney U and Chi-square tests. Results: The mean age of the participants was 35.48 ± 8.39 years. The frequency of the infertility in our study was 12.8% (n=73). The prevalence of infertility was higher in those with a history of gynecological disease or gynecologic surgery and in those with menstrual irregularity (p<0.05; for each). The mean score on the UCLA Loneliness Scale was 32.16 ± 9.49 (from 20 to 70). In this study, no difference was found between the level of loneliness and who is responsible for infertility among infertile/fertile women (p≥0.05). Level of loneliness among the women with primary infertility was higher compared to the women with secondary infertility (p<0.05). Conclusion: The prevalence of infertility among the women was relatively high. It was concluded that prospective studies are needed in order to expose the relationship between the infertility and the level of loneliness in women.

Background: Childbearing for the first time is a unique experience. Quality of life is an important indicator in health studies. This study aimed to assess the quality of life of women who were conceived by ARTs and had successful childbirth for the first time and to compare it with quality of life in women who become pregnant naturally and similarly had successful childbirth for the first time. Materials and Methods: This was a cross sectional comparative study. The accessible sample was recruited from patients attending an infertility clinic and two obstetric and gynecology clinics in Tehran, Iran, during March 2010 to March 2011. In all 276 patients were approached. Of these, 162 women (76 women in natural conception group and 86 women in assisted reproduction technologies group) who met the inclusion criteria were entered into the study. Quality of life was assessed using the 36-item Short Form Health Survey (SF-36). Women completed the questionnaire at two time points: i. last trimester and ii. first month after delivery. Comparison was made between two groups using Mann-Whitney U test and paired samples t test. Results: Comparing the SF-36 scores between women in natural conception group and ARTs group before childbirth, it was found that natural group had better condition on physical functioning, role limitation due to physical problems, bodily pain and social functioning, while the ARTs group reported better status on general health, vitality, role limitation due to emotional problems, and mental health. However, after childbirth, the ARTs group reported a better condition almost on all measures, except for physical functioning. Comparing differences in obtained scores between two groups before and after childbirth, the results showed that improvements in health related quality of life measures for the ARTs group were greater in all measures, expect for general health. Conclusion: The findings from this study suggest that health-related quality of life was improved in women who became a mother for the first time by either method. Comparing to women who became mother by natural conception, women who received ARTs showed better quality of life from this first successful experience.

Background: Poor ovarian response (POR) to gonadotropin stimulation has led to a significant decline in success rate of fertility treatment. The immune system may play an important role in pathophysiology of POR by dysfunctions of cytokines and the growth factor network, and the presence of ovarian auto-antibodies. The aim of this study is to investigate the expression of toll-like receptors (TLR) 1, 2, 4, 5, 6 and cyclooxygenase (COX) 2 genes in follicular cells and concentration of interleukin (IL)-6, IL-8 and macrophage migration inhibitory factor (MIF), as major parts of innate immunity, in follicular fluid (FF) obtained from POR women in comparison with normal women. Materials and Methods: In this case-control study, 20 infertile POR patients and 20 normal women took part in this study and underwent controlled ovarian stimulation. The FF was obtained from the largest follicle (>18 mm). The FF was centrifuged and cellular pellet was then used for evaluation of expression of TLRs and COX2 genes by real-time PCR. FF was used for quantitative analysis for IL-6, IL-8 and MIF by enzyme-linked immunosorbent assay (ELISA). Results: TLR1, 2, 4, 5, 6 and COX2 gene expression were significantly higher in POR (p<0.05). Concentration of IL-6, IL-8 and MIF proteins was significantly increased in POR compared with normal women (p<0.05). Conclusion: These findings support the hypothesis that the immune system may be involved in pathophysiology of POR through TLRs.

Background: Ketamine, an injectable anesthetic in human and animal medicine, is also a recreational drug used by young adults. The aim of this study is to evaluate the effects of ketamine on membrane integrity, DNA fragmentation and sperm parameters in humans. Materials and Methods: This prospective study was conducted on 40 males with normal semen samples over one month (August 2012). Subjects were randomly allocated to four groups (Control and case I, II and III) whose semen samples were adjusted to different concentrations of ketamine (1, 3, 5 μL) for one hour. Sperm analysis was performed for routine parameters, motility and morphology. Evaluation of membrane integrity and DNA fragmentation was done by eosin-Y staining and the sperm chromatin dispersion (SCD) test, respectively. The results were analyzed by ANOVA and Tukey’s tests. P≤0.05 was considered statistically significant. Results: Total sperm motility in all case groups were significantly lower compared with the control group. In case group III, progressive motility showed significant difference with case group II. After addition of ketamine, sperm had evidence of coiled tails in all case groups compared to the control group however this observation was not significant. Evaluation of membrane integrity showed the rate of necrospermia increased in all case groups. However, ketamine only significantly affected membrane integrity in case group III. SCD staining showed that in the control group nucleoids with medium halos (63.44 ± 1.2) were significantly different compared to the case groups I (15.44 ± 0.45), II (9.05±1.16) and III (10.55 ± 1.14), respectively. Between case groups, nucleoids with large and medium halos showed significant differences in case groups II and III compared with case group I. Nucleoids with medium halos were significantly different between case groups II and III. Conclusion: Ketamine, through its effect on membrane integrity and DNA fragmentation, decreased sperm viability and caused abnormal sperm parameters in progressive motility.

Klinefelter syndrome (KS) is the most common sex chromosomal disorder in men. Most of these patients show the 47,XXY karyotype, whereas approximately 15% of them are mosaics with variable phenotype. A 39-year-old male investigated for primary infertility, was clinically normal with small firm testes and elevated levels of FSH, LH and low level of testosterone. Total azoospermia was confirmed on semen analysis. Testicular histopathology revealed no spermatogenesis and absence of germ cells. Karyotype from whole blood culture showed cells with 47,XXY/46,XX/ 45,X/48,XXXY/ 46,XY mosaicism. The predominant cell line was 47,XXY (83.67%). This was confirmed by fluorescence in situ hybridization (FISH). Also the presence of a small population of cells with the 48,XXXY and 45,X karyotypes was detected by FISH. This case illustrates the utility of FISH as an adjunct to conventional cytogenetics in assess the chromosome copy number in each cell line of a mosaic.
