However, its role in spermatogenesis remains unclear. Recent transcriptomic analyses suggest a potential link between KIF2C and male infertility. This study aimed to clarify KIF2C's roles in spermatogenesis using Kif2c knockout (KO) mice.Methods: To overcome the preweaning lethality associated with Kif2c deletion, we generated Kif2c KO mice with a mixed genetic background of 129X1/SvJ and B6D2. We assessed male fertility, epididymal sperm counts, and testicular sections of Kif2c KO mice.Results: Global Kif2c KO mice were obtained and showed male infertility. Histological analyses and epididymal sperm count revealed that Kif2c KO mice exhibited severely impaired spermatogenesis and absence of mature spermatozoa. These findings are consistent with those observed in patients with nonobstructive azoospermia (NOA). Our classification of Kif2c KO seminiferous tubules indicated that most spermatogenic cells were arrested at the early stages, particularly during meiosis.Conclusions: This study provides in vivo evidence that KIF2C is essential for spermatogenesis and male fertility in mice. The successful generation of global Kif2c KO mice establishes an animal model for NOA, supporting research on germ cell development and reproductive health.","PeriodicalId":21116,"journal":{"name":"Reproductive Medicine and Biology","volume":"24 1","pages":"e12659"},"PeriodicalIF":2.7,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12107603/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exosome therapy emerges as a promising cell-free treatment. However, research into the molecular mechanisms of exosome repair in ovarian diseases is still in its infancy. By establishing models of oxidative stress in ovarian granulosa cells and POI in mice, we aim to explore whether human umbilical cord mesenchymal stem cell exosomes can repair oxidative damage in ovarian granulosa cells and mouse ovaries, as well as identify potential targets of action. Our goal is to provide new ideas and methods for the clinical application of exosomes and the early prevention and treatment of POI.Methods: Hydrogen peroxide (H2O2) (200 μM, 2 h) and D-galactose (D-gal) (200 mg/kg, 56 days) were used to induce oxidative stress in ovarian granulosa cells and mice, respectively. Subsequently, exosomes were added to the injury model to validate the mechanism of exosome repair of oxidative damage. We evaluated senescence indicators, AMPK activation, and autophagy.Result: Through the execution of in vivo and in vitro experiments, it was observed that the activation of the AMP-activated protein kinase (AMPK) pathway is induced by exosome intervention, leading to a reduction in the accumulation of autophagic vesicles and the restoration of the patency of autophagic flow. This, in turn, results in the repair of oxidative stress-induced damage and the enhancement of the function of damaged cells and ovaries.Conclusion: Our findings indicate that exosomes derived from human umbilical cord stem cells have the beneficial effect of ameliorating oxidative stress-induced POI by activating AMPK and regulating autophagic homeostasis.","PeriodicalId":21116,"journal":{"name":"Reproductive Medicine and Biology","volume":"24 1","pages":"e12658"},"PeriodicalIF":2.7,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12106360/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Embryonic selection using time-lapse observations is helpful for successful embryo transfer; however, information on the effect of male aging on time-lapse is insufficient. We analyzed the impact of paternal aging on sperm characteristics, embryonic developmental kinetics, embryo evaluation score, and pregnancy outcomes.Methods: We used data from patients treated at our clinic between January 2020 and December 2022. We evaluated the effects of aging in men and women on semen data, in vitro fertilization (IVF) results, developmental kinetics, embryo evaluation scores, and embryo transfer outcomes using a retrospective approach.Results: Male aging adversely affected the semen characteristics. Although female aging had adverse effects on IVF, embryonic developmental kinetics, and embryo transfer outcomes, male aging did not have such a significant impact. Female aging decreased the iDAScore and Gardner criteria, whereas male aging did not affect the iDAScore.Conclusions: Aging in males had a negative effect on semen data.

This review explores the potential of gonadal shielding during TBI and treosulfan-based conditioning as strategies to optimize treatment efficacy while preserving fertility.Methods: A PubMed search up to February 2025 was performed for English, peer-reviewed articles on hematologic malignancies, HSCT, shielding, and treosulfan. Studies on oncologic outcomes and fertility in pediatric and AYA patients were included.Main findings: Ovarian shielding during myeloablative conditioning with TBI effectively reduces ovarian radiation exposure, resulting in improved menstrual recovery and hormone profiles. A treosulfan-based regimen demonstrated higher antitumor activity than a reduced-intensity busulfan-based regimen in randomized controlled trials. In a retrospective analysis, the treosulfan-based regimen exhibited lower gonadal toxicity than the busulfan-based regimen, although careful attention must be paid to dosing settings of the regimens.Conclusion: Ovarian shielding during TBI and a treosulfan-based regimen hold the potential to preserve the reproductive capacity of patients undergoing HSCT.
