Sperm production and maturation depends on the hypothalamic-pituitary-testis axis control. Therefore, the objective of the current study was to evaluate the effects of chronic stress on the neuroendocrine control of male reproduction, the oxidative status in the epididymis, and male fertility. Adult male rats were assigned to control or chronic stress groups. Chronically stressed males were exposed to cold-water immersion (CWI) for 50 consecutive days. After euthanasia, the hypothalamus was dissected for Kisspeptin (Kiss1) and Gonadotropin releasing hormone (GnRH) evaluation; serum luteinizing hormone (LH), testosterone (T), and corticosterone concentrations were determined. In the epididymis, reactive oxygen species (ROS), lipid peroxides, and content of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx4) were assessed. Sperm motility, viability, concentration, morphology and acrosomal reaction were assessed. Epididymal sperm were used for in-vitro fertilization with oocytes from intact female rats. Stressed males showed lower hypothalamic Kiss1 and GnRH content, lower LH and T concentration, together with higher serum corticosterone concentration. ROS production, and lipid peroxides increased in all epididymal regions, while SOD, CAT, and GPx4 content decreased after chronic stress; sperm quality was also lower. The percentage of fertilized oocytes decreased, and embryonic development was low, compared to controls. Together, these results show that chronic stress disrupts neuroendocrine control of male reproduction and generates oxidative stress in the epididymis. These effects disturb sperm quality, leading to low fertilizing potential and poor embryonic development.</div></div>","PeriodicalId":21018,"journal":{"name":"Reproductive biology","volume":"25 3","pages":"Article 101027"},"PeriodicalIF":2.5,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Connexin (Cx) gap junction proteins play an important role in the communication among granulosa cells and cumulus cells and are impacted by bisphenols and linked to specific miRs. We hypothesize that miR-21 downregulation and BPA exposure affect Cxs mRNA and downstream miRNAs expression. Oocyte maturation was unaffected by miR-21 downregulation, but was significantly decreased (p = 0.0059) following BPA exposure. Also, BPA significantly increased Cx 43 mRNA levels when miR-21 is knocked-down in cumulus cells (p = 0.0476). miR-378a, a target of Cx 43 and 37, increased due to BPA and combination treatment in denuded oocytes (p = 0.0349) and cumulus cells (p = 0.0177). miR-96, a Cx 26 target, displayed a significant decrease in all samples following BPA exposure, in a miR-21 independent manner (p &lt; 0.05).

Various parameters were evaluated, including zoometric and metabolic measurements, estrous cyclicity, ovulation, and follicular development. The ovaries and uterus were histologically analyzed using hematoxylin-eosin staining. Furthermore, ovarian GLUT4 protein levels were estimated by Western blotting and fluorescence microscopy to investigate its association with metabolic and reproductive dysfunctions observed in this model. Zucker fatty rats exhibited significant body weight and adiposity index increases, accompanied by elevated cholesterol, triglycerides, and insulin levels. Conversely, progesterone levels were found to be significantly reduced. Histological analysis of ovarian morphology revealed pre-cystic follicles, a diminished follicular population, and a reduced number of corpora lutea. Additionally, a decrease in ovarian GLUT4 protein expression was observed. The uterine analysis demonstrated a smaller overall area, with notable reductions in both endometrial and myometrial thickness and fewer uterine glands. These findings indicate that in Zucker fatty rats, decreased ovarian GLUT4 protein expression and impaired glucose homeostasis are strongly associated with significant morphological alterations in the ovaries and uterus.</div></div>","PeriodicalId":21018,"journal":{"name":"Reproductive biology","volume":"25 2","pages":"Article 101025"},"PeriodicalIF":2.5,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, the potential genes regulating decidualization have not been elucidated. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) is widely used in gene expression studies, with relative quantification being the predominant method due to its simplicity, cost-effectiveness, and lower sample requirements. This method determines gene expression levels by normalizing to reference genes. However, the selection of stable reference genes for studies on decidualization remains a challenge. Based on the RNA-seq dataset from human endometrial stromal cells (ESCs) and differentiated ESCs (DESCs), ten new candidate reference genes were identified. The expression of these ten candidates, along with the commonly used reference gene β-actin, was measured in ESCs, DESCs, and decidual stromal cells (DSCs) through RT<img>qPCR. Five algorithms were used to systematically identify suitable reference genes. The results indicated that <em>Staufen double-stranded RNA binding protein 1 (STAU1)</em> was most stable for induced decidualization in vitro, showing consistent expression in ESCs and DSCs. Using <em>STAU1</em> as the reference gene, the expression levels of <em>insulin like growth factor binding protein 1</em> and <em>prolactin</em> in DESCs were significantly higher than those in ESCs. <em>Stau1</em> was further validated with both natural pregnancy and artificially induced decidualization mouse models.

Testes (n = 10) were obtained post-mortem from ten different, sexually mature Karakul rams and scanned using an 8-MHz linear-array transducer in both longitudinal (Long) and transverse (Trans) planes.

Two segmentation approaches were compared to assess their ability to detect quantitative correlations between echotextural characteristics and proximate chemical composition of testicular tissue: echointensity (EI) banding and algorithmic segmentation of the bitmaps. Using 50- or 25-pixel intensity bands, only two Long EI bands and five Trans EI bands showed significant correlations between MPI, MPH, or MPC and testicular tissue constituents.

Research on AMH in felids began in 2011 and given the increasing number of studies over recent years, an updated literature review is necessary to clarify and organize future research directions. The objective of this article was to conduct a systematic review of AMH in domestic and wild felids. From a literature search of international publications, 23 were selected for inclusion. AMH determinations were performed using commercial enzyme-linked immunosorbent assays (ELISA) and electrochemiluminescence immunoassays (EQLIA). In female felids, AMH concentrations decrease with age, along with follicular reserve diminution. AMH can also be used to diagnose granulosa cell ovarian tumors and cryptorchidism in females and males, respectively. This hormone serves as a marker for reproductive status and can reflect gonadal function in both genders. Furthermore, AMH may prove to be a valuable predictive tool for reproductive biotechnologies in both domestic and wild felids. Several aspects of this hormone still remain to be elucidated, including its variations throughout the estrous cycle and the effect of photoperiod.
