Animal studies have demonstrated that NMN supplementation enhances mitochondrial function, reduces oxidative stress, and modulates sirtuin activity in ovarian tissue. These effects contributed to improved oocyte quality, delayed ovarian senescence, and prolonged reproductive lifespan.

Furthermore, the anti-inflammatory and anti-apoptotic properties of NMN suggest potential therapeutic applications in conditions such as premature ovarian insufficiency and polycystic ovary syndrome. Despite encouraging findings in rodent models, clinical translation remains limited. This review summarizes the key molecular pathways influenced by NMN, including the NAD+/sirtuin-1 (SIRT1) axis, and highlights important gaps in current knowledge.

Serum levels of interleukin (IL)-6 and IL-1β were assessed at three time points. Histopathological examination was conducted to evaluate the presence of endometriotic tissue, fibrosis, abscess formation, and adipose tissue remodeling.</p><p><strong>Results: </strong>Rats treated with HAG showed a significant reduction in lesion size (6.8 mm² vs. 81 mm², p<0.001) and significantly lower adhesion scores (p<0.001). Persistent endometriosis was observed in only 36% of animals in the HAG group compared with 95.5% in the control group (p<0.001). Histological analysis demonstrated fewer fibrotic and purulent reactions and a shift toward adipose tissue remodeling in the HAG-treated animals. Serum IL-6 and IL-1β levels decreased significantly in the HAG group, whereas both cytokines increased in the control group (p<0.001 for both).</p><p><strong>Conclusion: </strong>HAG significantly improved macroscopic, histological, and biochemical outcomes in this experimental model. These findings suggest that HAG may serve as a biologically active adjunct for reducing postoperative adhesion formation and inflammation in endometriosis.</p>","PeriodicalId":46409,"journal":{"name":"Clinical and Experimental Reproductive Medicine-CERM","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148406241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
