Therefore, dysfunctional expression of this gene results in abnormal spermatogenesis. On the other hand, DNA damage in spermatozoa is considered to be an important cause of male infertility, and the presence of sperm with DNA fragmentation and chromatin abnormalities in human ejaculates is well documented, in particular in men with poor semen quality. Therefore, the aim of this study is to evaluate HSPA2 expression and its relation with DNA fragmentation, protamine deficiency involved in DNA packaging and semen parameters in varicocele patients in comparison to fertile men before and after varicocelectomy. Materials and methods This study included 52 fertile individuals as the control group and 70 infertile individuals with varicocele as the experimental group. Sperm DNA fragmentation, protamine deficiency and relative HSPA2 expression were evaluated by the sperm chromatin dispersion test, chromomycin A3 staining and RT-PCR, respectively. Results The mean values of abnormal morphology, protamine deficiency and DNA fragmentation were significantly lower in varicocele individuals following varicocelectomy when compared to fertile individuals. The correlation between these parameters were studied and discussed in the text. Conclusion There is a decrease in relative HSPA2 expression which is possibly due to chronic induced hyperthermia in varicocele individuals. Removal of this stress increases HSPA2 expression and results in the proper folding of proteins involved in spermatogenesis; therefore resulting in improved DNA packaging, as well as better sperm morphology and motility which may indirectly reduce sperm DNA fragmentation.  }, keywords = {Varicocele,HSPA2,Protamines,DNA fragmentation,surgery}, url = {https://www.ijfs.ir/article_45805.html}, eprint = {https://www.ijfs.ir/article_45805_3830e49e309f6d3c727fa5c51ba53062.pdf} } @article { author = {García-Herrero, Sandra and Garrido, Nicolás and Martínez-Conejero, José Antonio and Remohí, José and Pellicer, Antonio and Meseguer, Marcos}, title = {Profound Transcriptomic Differences Found between Sperm Samples from Sperm Donors vs. Patients Undergoing Assisted Reproduction Techniques Tends to Disappear after Swim-up Sperm Preparation Technique}, journal = {International Journal of Fertility and Sterility}, volume = {4}, number = {3}, pages = {114-121}, year = {2010}, publisher = {Royan Institute, Iranian Academic Center for Education Culture and Research (ACECR)}, issn = {2008-076X}, eissn = {2008-0778}, doi = {10.22074/ijfs.2010.45807}, abstract = {Background Although spermatozoa delivers its RNA to oocytes at fertilization, its biological role is not well characterized. Our purpose was to identify the genes differentially and exclusively expressed in sperm samples both before and after the swim-up process in control donors and infertile males with the purpose to identify their functional significance in male fertility. Materials and methods This was a nested case-control study. Ten sperm samples were obtained from infertile patients [n=5 (two aliquots each from five samples; one before the swim-up process and one after)] and donors [n=5 (two aliquots from five samples, one before the swim-up process and one after)]. Oligonucleotide microarrays were employed to study the genome-wide expression of pooled samples from infertile patients vs. donors. A total of four microarrays were perfomed: two with sperm sample aliquots before swim-up and two with sperm samples aliquots after swim-up, from both the case and control groups. The results were evaluated to detect which genes expressed differentially [fold change (FC)>5 and p <0.05] and which genes were exclusive to each of the groups, both before and after swim-up. Results Profound differences were detected between the fresh sperm samples of donors vs. infertile patients with respect to both differentially and exclusively expressed genes. Nevertheless these differences seemed to decrease after the swim-up selection process. Conclusion There are important differences between the expression profiles of sperm samples of fertile donors vs. infertile patients who require assisted reproduction techniques (ART). These differences are potential forecasters of fertility success, although their reliability needs to be explored further.}, keywords = {Gene expression,infertility,Microarray Analysis,Spermatozoa}, url = {https://www.ijfs.ir/article_45807.html}, eprint = {https://www.ijfs.ir/article_45807_56225a51f928a7d4ae9851e4eece379f.pdf} } @article { author = {Salehpour, Saghar and Esmaeilnia Shirvani, Hamidreza and Entezari, Abbas}, title = {Evaluation of the Prevalence of Polycystic Ovarian Syndrome among Adolescent (15-18 Years Old) Girls in Tehran during 2005-2006}, journal = {International Journal of Fertility and Sterility}, volume = {4}, number = {3}, pages = {122-127}, year = {2010}, publisher = {Royan Institute, Iranian Academic Center for Education Culture and Research (ACECR)}, issn = {2008-076X}, eissn = {2008-0778}, doi = {10.22074/ijfs.2010.45808}, abstract = {Background Polycystic ovarian syndrome (PCOS) was first introduced by Leventhal and Stein in 1935. It has a wide range of manifestations such as hyperandrogenism, irregular menstruation and central body obesity. The lack of definite diagnostic criteria has made the diagnosis a difficult task. Moreover, the disturbing aspects of the syndrome range from hirsutism in an adolescent girl to infertility in a young woman. Based on the Rotterdam 2003 Criteria, current diagnostic criteria must include two of the following three symptoms: 1. Either oligo-ovulation or anovulation, 2. Clinical or laboratory manifestations of hyperandrogenism, 3. Polycystic ovaries on sonographic examination (more than 12 follicles of less than 10 mm in diameter in each ovary). In this study, we have focused on the enrollment of a large sample size to assess the prevalence and clinical features of PCOS such that a wide range of basic information can be utilized for further investigations. Materials and methods This was a cross-sectional study with multi-stage random sampling. Subjects were selected from 15-18 years old girls from a number of high schools in Tehran. After interview and clinical examination, those individuals with either menstrual irregularities, hirsutism or obesity were referred for further laboratory evaluations and abdominal sonography in order to diagnose PCOS and estimate its prevalence. We also aimed to assess the predominant features of this disorder among adolescents. Results The overall prevalence of the syndrome was 3.42%. Out of the 1430 girls, 49 were diagnosed with PCOS. Conclusion Despite its high prevalence, this syndrome has not been widely studied. Most of the conducted studies have enrolled small samples within a short time period. Thus, more accurate policy making in this regard can be achieved through definition of the prevalence of PCOS and accurate estimation of its burden.}, keywords = {}, url = {https://www.ijfs.ir/article_45808.html}, eprint = {https://www.ijfs.ir/article_45808_3cfa692a659f21ff78d6bae8f5827778.pdf} } @article { author = {Hadi, Negin and Barazandeh, Fariba and Azad, Fariborz}, title = {The Prevalence of Chlamydia trachomatis Infection in Women Attending Health Clinics in Shiraz, Islamic Republic of Iran}, journal = {International Journal of Fertility and Sterility}, volume = {4}, number = {3}, pages = {128-133}, year = {2010}, publisher = {Royan Institute, Iranian Academic Center for Education Culture and Research (ACECR)}, issn = {2008-076X}, eissn = {2008-0778}, doi = {10.22074/ijfs.2010.45809}, abstract = {Background Chlamydia trachomatis (CT) is a common cause of sexually transmitted infections (STI) and a prevalent microorganism found in the vaginal discharge of sexually active women. The infection usually has no symptoms; although it may cause chronic complications such as pelvic inflammatory disease (PID), ectopic pregnancy, chronic pelvic pain, tubal infertility and cervical cancer. This study was done, for the first time, in Shiraz (southern Iran) to determine the prevalence of genital C.T in women Materials and methods A total of 402 women who referred for routine pap smears to randomly selected health centers in Shiraz were tested with the IMAGEN Chlamydia test, a direct immunofluorescence test for the detection of Chlamydia in human urogenital specimens. The results of this test were compared to the socio-demographic condition of each participant as well as their sexually transmitted disease (STD) symptoms, both present and past. Results The prevalence rate of Chlamydia infection was 8% (32/402). No correlation was found between this infection and age, marital age, number of children, education and occupational status of the participants. On the other hand, the correlation between the presence of infection and a positive history of STD symptoms, both present and past was significant. Conclusion Chlamydia infection is quite frequent in our society, where knowledge about STD infections is scant. Considering the sequelae of this infection and the fact that this is a quiet disease, it seems rational to screen sexually active women and inform them more about this issue.}, keywords = {sexually transmitted infection,Chlamydia trachomatis,Direct Immunofluorescence,Endocervical Specimen}, url = {https://www.ijfs.ir/article_45809.html}, eprint = {https://www.ijfs.ir/article_45809_f360697b473f4aab7ef1c39db51902e9.pdf} } @article { author = {Bagheri, Morteza and Abdi Rad, Isa and Omrani, Mir Davood and Nanbakhsh, Fariba}, title = {C677T and A1298C Mutations in the Methylenetetrahydrofolate Reductase Gene in Patients with Recurrent Abortion from the Iranian Azeri Turkish}, journal = {International Journal of Fertility and Sterility}, volume = {4}, number = {3}, pages = {134-139}, year = {2010}, publisher = {Royan Institute, Iranian Academic Center for Education Culture and Research (ACECR)}, issn = {2008-076X}, eissn = {2008-0778}, doi = {10.22074/ijfs.2010.45810}, abstract = {Background To assess whether the C677T and A1298C mutations in the methylenetetrahydrofolate reductase (MTHER) gene are associated with recurrent abortion (RA), we determined the frequencies of the T677 and C1298 mutations in patients and controls.

Early diagnosis of this condition with the use of ultrasound imaging allows for preserving the uterus and subsequent fertility.

With increasing incidence of cesarean sections (CS) worldwide and more liberal use of transvaginal sonography (TVS) in early pregnancy, more cases of cesarean scar pregnancy (CSP) are diagnosed. Thus every woman with a previous CS presenting to the early pregnancy unit should have a routine check for the cesarean scar appearance.
