To investigate the impact of miRNA profiles in granulosa cells and follicular fluid, crucial players in follicle development, this study employed a computational network theory approach to reconstruct potential pathways regulated by miRNAs in granulosa cells and follicular fluid of women suffering from DOR. Available data from published research were collected to create the FGC_MiRNome_MC, a representation of miRNA target genes and their interactions. 365 hubs were identified within the network, representing potential key regulators, and 210 nodes that act as both hubs and bottlenecks (H&BN nodes), suggesting that they may control the information flow within the network. GO enrichment analysis of the 210 H&BN nodes revealed their involvement in fundamental cellular processes relevant to ovarian function. In particular, the cluster analysis identified several shared pathways between cluster 1 and cluster 2 involved in the RAS/MAPK pathway, which plays a critical role in cell proliferation, differentiation and survival. These findings suggest that miRNAs play a significant role in DOR and highlight the potential of the RAS/MAPK pathway as a target for further investigation.

This review explores the clinical applications and outcomes of three primary methods: testicular sperm aspiration (TESA), testicular sperm extraction (TESE), and microdissection TESE (mTESE). TESA remains a practical, minimally invasive solution for obstructive azoospermia, offering high success rates. However, its limited effectiveness in non-obstructive azoospermia (NOA) highlights the need for more refined approaches. mTESE has emerged as the preferred method in NOA cases due to its microsurgical precision, higher sperm retrieval rates, and reduced damage to testicular tissue. Multiple factors influence the success of these procedures, including patient age, testicular volume, hormone levels, and underlying histopathology. The identification of reliable predictive biomarkers such as follicle-stimulating hormone (FSH), inhibin B, anti-Müllerian hormone (AMH), and TEX101 has enhanced patient selection and procedural planning. Additionally, imaging techniques and metabolite profiling are emerging as valuable non-invasive tools for predicting outcomes. The integration of AI and machine learning into clinical practice further supports individualized treatment strategies by improving predictive accuracy and intraoperative decision-making. Despite clinical success, ethical and psychosocial considerations remain central to the comprehensive care of affected individuals. Financial constraints and unequal access to specialized reproductive services also pose challenges. Future efforts should prioritize the development of validated predictive models, the expansion of biomarker research, and the implementation of standardized clinical protocols.
