Advanced Glycation end-products (AGEs) cause oxidative damage to the follicles of the ovary. This study aims to investigate the correlation of follicular fluid soluble receptor of AGEs (FF sRAGE) with fertility-related parameters in infertile women with endometriosis. From January 2012 to July 2015 twenty-four women diagnosed with mild to moderate endometriosis aged 28-38 years underwent assisted reproduction. sRAGE levels measured in FF were related to lifestyle factors, sociodemographic characteristics, gynaecological and obstetric parameters, hormonal status and fertilization. sRAGE was inversely associated with BMI (r = -0.503, p = 0.012). No significant association of sRAGE with age (p = 0.714) or alcohol consumption (p = 0.882) was found. Pearson's r correlation coefficient revealed that sRAGE was positively associated with serum AMH (r = 0.518, p = 0.009), FF AMH (r = 0.630, p = 0.001), number of follicles >15mm (r = 0.601, p = 0.002), total number of follicles aspirated (r = 0.698, p < 0.001), total number of MII oocytes obtained, (r = 0.757, p < 0.001) and the number of embryos with good embryo scoring (suitable for ET) (r = 0.522, p = 0.009).

Male infertility is a problem in 7% of all men. In vitro spermatogenesis (IVS) is the experimental approach that has been developed for mimicking seminiferous tubules-like functional structures in vitro. Currently, various researchers are interested in finding and developing a microenvironmental condition or a bioartificial testis applied for fertility restoration via gamete production in vitro. The tissue engineering (TE) has developed new approaches to treat male fertility preservation through development of functional male germ cells. This makes TE a possible future strategy for restoration of male fertility. Although 3D culture systems supply the perception of the effect of cellular interactions in the process of spermatogenesis, formation of a native gradient of autocrine/paracrine factors in 3D culture systems have not been considered. These results collectively suggest that maintaining the microenvironment of testicular cells even in the form of a 3D-culture system is crucial in achieving spermatogenesis ex vivo. It is also possible to engineer the testicular structures using biomaterials to provide a supporting scaffold for somatic and stem cells. The insemination of these cells with GFs is possible for temporally and spatially adjusted release to mimic the microenvironment of the in situ seminiferous epithelium. This review focuses on recent studies and advances in the application of TE strategies to cell-tissue culture on synthetic or natural scaffolds supplemented with growth factors.","PeriodicalId":13006,"journal":{"name":"Human Fertility","volume":" ","pages":"1617-1635"},"PeriodicalIF":1.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41128902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
