Extracellular vesicles are central to this post-testicular maturation and changes in their composition could directly impact male reproductive health, sperm quality and post-fertilisation development. This study aimed to characterise and compare extracellular vesicles isolated from distinct regions of the male reproductive tract. Extracellular vesicles were isolated from adult, male C57BL/6J cauda and caput epididymis (epididymosomes) and seminal vesicle fluid by precipitation and size exclusion chromatography. Isolated vesicles were characterised using nanoparticle tracking analysis, transmission electron microscopy, Western blotting and imaging flow cytometry. Epididymosomes and seminal fluid vesicles ranged from 110.26 to 121.26 nm in diameter, had a concentration of 109 to 1010 particles/cm3 and had a typical round, cup-shaped morphology. The size and concentration of extracellular vesicles from the caput were significantly larger than those from the cauda and seminal fluid. Imaging flow cytometry revealed that all isolated extracellular vesicles expressed CD81 and CD9 tetraspanins; however, CD63 was detected only in caput epididymosomes. Furthermore, there were significantly fewer CD9+ vesicles in seminal fluid EVs compared to epididymosomes. Using a range of bulk- and single-vesicle analytical approaches, we show that different regions of the male reproductive tract display distinct vesicle compositional phenotypes. However, additional studies are warranted to define the significance of this heterogeneity, their roles in regulating male reproductive health and the development of their offspring.</p>","PeriodicalId":21127,"journal":{"name":"Reproduction","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12152732/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144151464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oocytes enter meiosis in the fetal ovary and then arrest at prophase I until sexual maturation. Upon hormonal stimulation, a subset of oocytes resumes meiosis. Oocytes then complete meiosis I, enter metaphase II and arrest until fertilization, a process essential for egg competency. The MOS kinase is a key regulator of the metaphase II arrest, activating the MAPK signaling cascade. Loss of MOS in female mice disrupts the maintenance of the metaphase II arrest, with some eggs extruding two polar bodies and some dividing beyond anaphase II. To investigate the consequences of the Mos deletion, we performed live imaging and found that mos-/- eggs exhibit transient chromosome separation events in meiosis I, suggesting a role for MOS in coordinating the timing of meiotic divisions. Further analysis showed that new transcription is required for mos-/- eggs to undergo additional divisions but not for second polar body (PB) extrusion. Surprisingly, single-egg sequencing revealed extensive differences in gene expression between wild-type (WT) and mos-/- eggs, including those with only one PB. Many differentially expressed genes were involved in cell cycle regulation, including Aurka, Bub3 and Cdk7. Upregulated pathways included metabolism of RNA, transcription and neddylation. Furthermore, the gene expression profile of mos-/- eggs was markedly different from that of chemically activated WT eggs. Our findings demonstrate that MOS plays a crucial role in meiotic cell cycle regulation and helps ensure that the egg maintains the proper transcriptome necessary for developmental competence.</p>","PeriodicalId":21127,"journal":{"name":"Reproduction","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12239712/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144151462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can be caused by excess insulin resistance, a failure to augment insulin secretion in response to pregnancy, or both. The risk of developing GDM is affected by several maternal morbidities, some of which are modifiable. Personal or family history of GDM or type 2 diabetes is strongly associated with GDM, and some susceptibility alleles for type 2 diabetes are shared with GDM. Social determinants of health including access to care and nutritional availability are also associated with GDM risk. Obesity is particularly associated with insulin resistance and dyslipidemia, which are risk factors for GDM. These factors are also present in polycystic ovarian syndrome (PCOS), and women with this condition have an elevated risk of GDM. While dysfunctional beta cell compensation may also be present before pregnancy and predispose to GDM, symptoms only manifest in pregnancy. Other factors that may increase the risk of GDM include folic acid supplementation, age of either of the parents and interpregnancy interval. Not only are preexisting maternal morbidities associated with the development of GDM, but women who have experienced a pregnancy complicated by GDM are more likely to develop type 2 diabetes and cardiovascular disease later in life.

This study investigated the impact of superovulation on ovarian perifollicular neoangiogenesis using light sheet fluorescence microscopy (LSFM), and by quantitatively profiling the three-dimensional (3D) perifollicular capillary bed in murine antral follicles. Dioestrus CD1 mice received 2.5, 5.0 or 7.5 IU pregnant mare serum gonadotrophin (PMSG) intraperitoneally, and ovaries were collected 24 and 48 h later, with those from normal cycling females (dioestrus, proestrus or oestrus) as controls. Ovaries were fixed and labelled with fluorescently tagged wheat germ agglutinin lectin and anti-CD34 to visualise the oocyte zona pellucida and thecal vasculature, respectively. Optically cleared samples were imaged using LSFM, and 3D volume rendering, vessel segmentation and image analysis were performed using Arivis Vision 4D and Fiji. Quantitative metrics including vessel volume, length, branching, density, spatial arrangement and oocyte characteristics were profiled. Statistical analysis was based on Kruskal-Wallis tests.

The early angiogenesis observed at 7.5 IU may reflect a compensatory mechanism, while the reduced density at 2.5 IU suggests an insufficient angiogenic response.

Oligo/anovulation is the most common feature of PCOS, and leads to subfertility. This may require induction of ovulation with medical therapies, such as oestrogen receptor antagonists, aromatase inhibitors or by giving exogenous follicle-stimulating hormone, which are effective for most women with PCOS.

Optimisation of pre-conception health, including weight management, is recommended in order to maximise fertility potential and improve pregnancy outcomes. The other key feature of PCOS is hyperandrogenism, which may contribute to ovulatory dysfunction and results in hirsutism and persistent acne, and also negatively impacts mental health, quality of life and psychosexual function.
