en 37663424 <p>Endometrial cancer (EC) ranks as the second most common gynaecological cancer worldwide. EC patients are diagnosed at an early clinical stage and generally have a good prognosis. Therefore, there is a dire need for development of a specific marker for early detection of endometrial adenocarcinoma. The development of EC is conditioned by a multistep process of oncogenic upregulation and tumor suppressor downregulation as shown by molecular genetic evidence. In this setting, microRNAs appear as significant regulators of gene expression and several variations in the expression of microRNAs have been implicated in normal endometrium, endometrial tissue, metrorrhagia, and endometrial cancer. Furthermore, microRNAs act as highly precise, sensitive, and robust molecules, making them potential markers for diagnosing specific cancers and their progression. With the rising incidence of EC, its management remains a vexing challenge and diagnostic methods for the disease are limited to invasive, expensive, and inaccurate tools. Therefore, the prospect of exploiting the utility of microRNAs as potential candidates for diagnosis and therapeutic use in EC seems promising.</p> Biomarkers, Endometrial neoplasms, Gene therapy, MicroRNAs, Signal transduction 147 166 https://www.jri.ir/article/140193 https://www.jri.ir/documents/fullpaper/en/140193.pdf SomasundaramIndumatiDepartment of Stem Cell and Regenerative Medicine, D.Y.

en 37663429 <p>Background: The objective of the current study was comparing the impact of two staining techniques on semen morphological parameters and their influence on patient diagnosis. The ideal staining method should preserve cell integrity while providing detailed information.<br /> Methods: Semen samples from fifty men were stained using Diff-Quick or Spermac methods. Morphological parameters were classified based on the Tygerberg criteria, and final diagnosis was according to WHO manual guidelines. Statistical analysis was performed through conducting paired t-tests or Wilcoxon rank-sum tests, with GLIMMIX and Fisher&#39;s exact test for determining the significance (p&le;0.05).<br /> Results: Both staining methods highlighted head and tail regions, with Spermac offering better visualization of the midpiece. Spermac demonstrated fewer normal spermatozoa (2.8&plusmn;0.3%) compared to Diff-Quick (3.98&plusmn;0.4%; p=0.0385). Midpiece abnormalities were more evident with Spermac (55.7&plusmn;2.1%) than Diff-Quick (24.8&plusmn;2.0%; p&lt;0.0001). No significant difference was found in head and tail abnormalities (p&gt;0.05).<br /> Conclusion: Diff-Quick staining resulted in a higher proportion of normal spermatozoa, primarily due to its midpiece evaluation. The choice of staining method significantly impacts the diagnosis of infertile males. These findings have important implications for clinical practice and future research, suggesting the need for further investigations to assess different staining methods and determine optimal diagnostic thresholds.</p> Human, Morphology, Spermatozoa, Staining 166 171 https://www.jri.ir/article/140192 https://www.jri.ir/documents/fullpaper/en/140192.pdf LincolnJuniorFederal University of Rio de Janeiro, Rio de Janeiro, Brazil122563Andréda Cunha Barreto-ViannaFederal University of Paraná-Palotina, Paraná, Brazil122564Marianade MelloRio de Janeiro Sperm Bank (Banco de Sêmen do Rio de Janeiro), Rio de Janeiro, Brazil122565Alexandredos SantosFederal University of Paraná-Palotina, Paraná, Brazil122566Cristianeda Fonte RamosState University of Rio de Janeiro, Rio de Janeiro, Brazil122567PaulaFontouraRio de Janeiro Sperm Bank (Banco de Sêmen do Rio de Janeiro), Rio de Janeiro, Brazilcontato@bsrj.com.br1642

en 37663428 <p>Background: Sox2 (SRY box2) is an essential transcription factor that plays a vital role in spermatogenesis and regulates the genes in this process. Sox2 is important for pluripotency, self-renewal, and even spermatogonial stem cell differentiation. This gene is found in pluripotent and specialized cells, and it is involved in their biological activities.<br /> Methods: Protein-protein interaction (PPI) network analysis was performed during spermatogenesis using NCBI, STRING, and Cytoscape databases. Then, after isolating spermatogonial stem cells from 6 C57BL/6 mice, mouse embryonic stem cells and ES-like cells were prepared. In the following, Sox2 expression was examined in differentiated and undifferentiated spermatogonia by immunohistochemistry (IMH), immunocytochemistry (ICC), and Fluidigm PCR (polymerase chain reaction). Finally, the results were compared using the Kruskal-Wallis and Dunn tests at the significance level of p&lt;0.05.<br /> Results: The results of this experiment showed that contrary to expectations, Sox2 has cytoplasmic expression in undifferentiated cells and nuclear expression in differentiated cells in <em>in vitro</em> conditions. In addition, the expression of Sox2 increased during differentiation. Fluidigm PCR showed a significantly higher expression of Sox2 (p&lt;0.05) in differentiated compared to undifferentiated spermatogonia. Sox2 has an interaction with other genes during spermatogenesis such as Oct4, Nanog, Klf4, Stra8, Smad1, Tcf3, and Osm.<br /> Conclusion: Sox2, which is known as a pluripotency marker, has a vital role in spermatogenesis and could be a differential marker. Sox2 has strong connections with other genes such as Oct4, Nanog, Klf4, Tcf3, Osm, Stra8, Lim2, Smad1, Gdnf, and Kit.</p> Adult germline stem cells, Cell differentiation, Seminiferous tubules, Sox2 protein, Transcription factors 171 181 https://www.jri.ir/article/140190 https://www.jri.ir/documents/fullpaper/en/140190.pdf EmadRezaDepartment of Nanobiotechnology, Faculty of Biotechnology, Amol University of Special Modern Technologies, Amol, Iran122556HosseinAziziDepartment of Nanobiotechnology, Faculty of Biotechnology, Amol University of Special Modern Technologies, Amol, Iranh.azizi@ausmt.ac.ir112138ThomasSkutellaInstitute for Anatomy and Cell Biology, Medical Faculty, University of Heidelberg, Heidelberg, Germany112141

en 37663421 <p>Background: The purpose of the current study was to determine the utility of early follicular phase follicle-stimulating hormone (FSH) testing in patients undergoing in vitro fertilization (IVF).&nbsp;<br /> Methods: This was a retrospective review of patients from 2012 to 2015 at Mayo Clinic in Rochester, Minnesota, USA. Included subjects had a normal anti-M&uuml;llerian hormone (AMH) of 1 to 9 <em>ng/ml </em>and antral follicle count (AFC) of 10 to 29. Patients were stratified by FSH level when associated estradiol was less than 50 <em>ng/ml.</em> In total, 225 patients were categorized into three groups: high FSH (FSH &ge;10 <em>IU/L</em>; n= 36), normal FSH (&gt;5 <em>IU/L</em> and &lt;10<em> IU/L</em>; n=170), and low FSH (FSH &le;5 <em>IU/L</em>; n= 19). ANOVA and multiple logistic regression were used for statistical comparisons and for evaluation of the relationships between variables; significance level was set at &lt;0.05.<br /> Results: There were no significant differences in demographics, IVF cycle type, or peak estradiol level between the groups. Patients with a high basal FSH level had a similar clinical pregnancy rate and live birth rate compared to controls and patients with low FSH. High FSH level was associated with decreased follicular development (17 versus 22; p&lt;0.01), oocyte yield (15 versus 18; p=0.02), and embryo yield (8 versus 10; p=0.04) despite higher total doses of gonadotropins.&nbsp;<br /> Conclusion: Patients with normal AMH and AFC levels could be further stratified into lower responders and starting doses of medications can be adjusted based on high basal FSH levels. Therefore, it is suggested to counsel patients on pregnancy outcomes which seem to be quite similar regardless of the FSH level.</p> Anti- mullerian hormone, Follicle stimulating hormone, In vitro fertilization, Ovarian reserve 181 188 https://www.jri.ir/article/140196 https://www.jri.ir/documents/fullpaper/en/140196.pdf ColleenMillerDivision of Reproductive Endocrinology and Infertility, Mayo Clinic, Minnesota, USA122578RyanMelikianSchool of Medicine, Wayne State University, Michigan, USA122579TiffannyJonesConceive Fertility Center, Texas, USA122580MackenziePurdyKindbody - St. Louis, Missouri, USA122581ZaraqKhanDivision of Reproductive Endocrinology and Infertility, Mayo Clinic, Minnesota, USA122582JessicaBleessDivision of Reproductive Endocrinology and Infertility, Mayo Clinic, Minnesota, USA122583ElizabethStewartDivision of Reproductive Endocrinology and Infertility, Mayo Clinic, Minnesota, USA122584CharlesCoddingtonDepartment of Obstetrics and Gynecology, Atrium Health Carolina’s Medical Center, North Carolina, USA122585ChandraShenoyDivision of Reproductive Endocrinology and Infertility, Mayo Clinic, Minnesota, USAshenoy.chandra@mayo.edu122586

en 37663425 <p>Background: Among several causes of infertility, urogenital infections seem to be influencing factors. The effect of bacterial or viral sexually transmitted infections (STIs) on human fertility is not well understood. The aim of this study was to determine the frequency of STIs in cervical samples of infertile and fertile women and study the relationship between these agents and infertility.&nbsp;<br /> Methods: In this case-control study, cytobrush was used for collecting of cervical sample from each infertile and fertile woman (n=95) who attended Research and Clinical Centers for Infertility in Kerman, Iran. PCR and real-time PCR methods were used to detect the presence of bacterial (genital <em>Ureaplasma</em> species, genital <em>Mycoplasma</em> species, <em>Chlamydia trachomatis (C. trachomatis)</em>, and <em>Gardnerella vaginalis</em>) and viral (herpes simplex virus, human papillomavirus (HPV), and Epstein-Barr virus) agents, respectively. Fisher&#39;s exact test and the logistic regression with the significance level of &le;5% were used for statistical analyses.<br /> Results: In general, 78.94% and 14.73% of specimens were positive for one or more studied microorganisms, respectively. Among studied agents, only the infection with HPV was significantly different between infertile and fertile groups (p=0.005) which may enhance the likelihood of female infertility (OR=5.30, 95% CI:1.47-19.11, p&lt;0.05). After adjusting for age, irregular menstrual cycle, abnormal vaginal discharge, and ectopic pregnancy, the odds ratio of infertility in HPV-infected women increased (OR=7.02, 95% CI:1.52-32.3, p&lt;0.05).&nbsp;<br /> Conclusion: Since HPV infection is asymptomatic, periodic screening of women in reproductive age especially infertile couples is recommended for early diagnosis and prevention of infection progression and cross contamination.</p> Female, Infertility, Iran, Sexually transmitted infections 188 198 https://www.jri.ir/article/140189 https://www.jri.ir/documents/fullpaper/en/140189.pdf ParastouHeidari PebdeniStudent Research Committee, Kerman University of Medical Sciences, Kerman, Iran122547FereshtehSaffariDepartment of Medical Microbiology (Bacteriology & Virology), Afzalipour Faculty of Medicine, Kerman University of Medical Sciences, Kerman, Iran122548Hamid RezaMollaeiDepartment of Medical Microbiology (Bacteriology & Virology), Afzalipour Faculty of Medicine, Kerman University of Medical Sciences, Kerman, Iran122549Toraj RezaMirshekariAfzalipour Clinical Center for Infertility, Kerman University of Medical Sciences, Kerman, Iran122550RobabehHosseini SadatDepartment of Obstetrics and Gynecology, School of Medicine, Kerman University of Medical Sciences, Kerman, Iran122551VictoriaHabibzadehDepartment of Obstetrics and Gynecology, School of Medicine, Kerman University of Medical Sciences, Kerman, Iran122552LidaSaeedDepartment of Obstetrics and Gynecology, School of Medicine, Kerman University of Medical Sciences, Kerman, Iran122553MoslemTaheri SoodejaniCenter for Healthcare Data Modeling, Department of Biostatistics and Epidemiology, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran122554RoyaAhmadrajabiMedical Mycology and Bacteriology Research Center, Kerman University of Medical Sciences, Kerman, Iranahmadrajabi3@ yahoo.com, r.ahmadi@kmu.ac.ir122555

en 37663427 <p>Background: In Brazil, donor anonymity is mandatory; however, the tendency of Brazilians towards the practice is unknown. In this study, an attempt was made to investigate whether couples undergoing assisted reproductive technology (ART) have a different perception of anonymous versus identity-release gamete donation than a target population in Brazil.<br /> Methods: This cross-sectional study was performed from September 1, 2020 to December 15, 2020. For that purpose, surveys through online platforms were conducted, including either patients undergoing ART (ART-group, n=400) or subjects interested in the theme (interested-group, n=100) randomized by age at a 1:4 ratio. The survey collected information on the participants&rsquo; attitudes towards anonymity of gamete donors, and answers were compared between the groups.<br /> Results: Most participants stated that the relationship between children and their parents would be affected by the child&#39;s knowledge of the origin of its conception. Most participants in the ART-group believed that the gamete donor&rsquo;s identity should not be revealed to the child, while only half of the interested-group stated the same. Most of the participants stated that &quot;the donor&#39;s identity should be revealed if the child questions its biological origin&quot;. &quot;From birth&quot; was the second most common response, while &quot;when the child turns 18 years old&quot; and &quot;sometime during teenage years&quot; were less common answers.<br /> Conclusion: The attitudes of ART patients about anonymity are conservative, with most participants believing that family relationships may be affected if the child is aware of the origin of his/her conception. These patients also believe that the identity of the gamete donor should not be revealed to the child.&nbsp;</p> Donor conception, Donor, Sperm, Survey 198 206 https://www.jri.ir/article/140191 https://www.jri.ir/documents/fullpaper/en/140191.pdf DouglasRochaAssociação Instituto Sapientiae-Centro de Estudos e Pesquisa em Reprodução Assistida, São Paulo, Brazil122557RoseMelamedAssociação Instituto Sapientiae-Centro de Estudos e Pesquisa em Reprodução Assistida, São Paulo, Brazil122558DanielaBragaAssociação Instituto Sapientiae-Centro de Estudos e Pesquisa em Reprodução Assistida, São Paulo, Brazil122559AmanadaSettiFertility Medical Group, São Paulo, Iran122560AssumptoIaconelliFertility Medical Group, São Paulo, Brazil122561EdsonBorgesFertility Medical Group, São Paulo, Braziledson@fertility.com.br122562

en 37663422 <p>Background: Fumarase deficiency is an autosomal recessive condition characterized by severe neurologic abnormalities due to homozygous mutations in the fumarate hydratase (FH) gene. Heterozygous carriers of FH mutations have increased risk of developing uterine fibroids that can be associated with hereditary leiomyomatosis and renal cell cancer (HLRCC). The association between FH mutations and infertility remains uncertain. The objective of our study was to characterize the infertility diagnoses, treatments, and outcomes in women presenting to a fertility center who were found to be carriers of fumarase deficiency based on the presence of heterozygous FH mutations.<br /> Case Presentation: A retrospective case series was conducted including 10 women presenting to an academic fertility center who were found to be FH carriers based on genetic carrier screening. Of the 9 women who were engaged in further workup, 2 had imaging results consistent with uterine fibroids. One woman underwent hysteroscopic myomectomy prior to two courses of ovulation induction with timed intercourse (OI/TIC) followed by one successful cycle of IVF. Of the remaining patients, only 1 woman successfully delivered after a cycle of ovulation induction with intrauterine insemination (OI/IUI). Other patients pursuing OI/IUI, OI/TIC, or monitored natural cycles had unsuccessful experiences.<br /> Conclusion: Patients with infertility who are offered genetic testing should be screened for FH mutations, as the carriers are at risk of developing HLRCC-associated uterine fibroids, which can influence fertility and pregnancy. Additional research is needed to investigate the impacts of FH mutations on infertility.</p> Fibroids, Fumarate hydratase, Genetic counseling, Hereditary leiomyomatosis and renal cell cancer (HLRCC), Infertility, Leiomyoma 206 212 https://www.jri.ir/article/140195 https://www.jri.ir/documents/fullpaper/en/140195.pdf JessicaSchwartzDonald and Barbara Zucker School of Medicine at Hofstra/Northwell, Hofstra University, New York, USAjessicaws737@gmail.com122574AlexandraPeyserDivision of Reproductive Endocrinology, Department of Obstetrics and Gynecology, Northwell Health Fertility, North Shore University Hospital, New York, USA122575MiriamTarrashDivision of Reproductive Endocrinology, Department of Obstetrics and Gynecology, Northwell Health Fertility, North Shore University Hospital, New York, USA122576RandiGoldmanDivision of Reproductive Endocrinology, Department of Obstetrics and Gynecology, Northwell Health Fertility, North Shore University Hospital, New York, USA122577

en 37663426 <p>Background: Mature teratoma is a benign neoplasm, mostly composed of well-differentiated derivations of almost two or three germ cell layers, while immature teratoma is a malignant neoplasm composed of immature neural and embryonic tissue. Immature teratoma in the context of ovarian endometrioma has not been reported yet.<br /> Case Presentation: A 34-year-old woman with primary infertility is reported in this study who suffered from immature teratoma associated with ovarian endometrioma. After several rounds of fertility treatment, the patient was referred for severe abdominal pain and underwent emergency surgery for the rupture of ovarian endometrioma. To preserve the ovary, the cyst was not resected in areas attached to the ovary. Some months later, the patient noticed a progressive abdominal enlargement. The sonographic evaluation revealed multiple solid-cystic lobulated masses on the abdominal wall and throughout the pelvic cavity. The histologic diagnosis was consistent with immature teratoma. The patient was treated with high-dose neoadjuvant chemotherapy and fertility-sparing surgery (FSS). The histologic evaluation of the extracted masses revealed teratoma maturation.<br /> Conclusion: This study reveals the importance of complete removal of endometrioma and highlights the role of neoadjuvant chemotherapy in fertility-sparing surgery and potentiating teratoma maturation.</p> Endometrioma, Fertility preservation, Immature teratoma, Neoadjuvant chemotherapy 212 216 https://www.jri.ir/article/140194 https://www.jri.ir/documents/fullpaper/en/140194.pdf SoheilaAmini MoghadamDepartment of Obstetrics and Gynecology, Firouzgar Hospital, Iran University of Medical Sciences, Tehran, Iran112284NiloufarSarchamiDepartment of Obstetrics and Gynecology, Firouzgar Hospital, Iran University of Medical Sciences, Tehran, IranNiloo.sarchami@gmail.com122538AliRahbariDepartment of Pathology, Jam Hospital, Tehran, Iran112418
