Special Issue Information

Dear Colleagues,

Male fertility is a complex trait regulated by coordinated cellular and molecular processes. Despite significant advances in reproductive biology, infertility affects a growing number of men worldwide, highlighting the urgent need to better understand the underlying mechanisms. Advances in molecular biology and reproductive technologies are now revealing the intricate networks that govern spermatogenesis, testicular function and hormonal regulation. This Special Issue aims to highlight cutting-edge research that uncovers the cellular and molecular mechanisms underlying male fertility, from germ cell development and Sertoli–Leydig cell interactions to epigenetic regulation and signaling pathways critical for fertility. We particularly welcome original research, reviews and perspective articles leveraging state-of-the-art approaches, such as single-cell omics, advanced imaging, CRISPR-based models and integrative systems biology, as well as contributions exploring genetic, environmental and lifestyle impacts on male reproductive function, to provide novel mechanistic insights or translational potential for diagnosis, therapy and fertility preservation. By bringing together the latest discoveries in cellular and molecular reproductive science, this Special Issue seeks to provide a comprehensive, forward-looking resource that will advance our understanding of male fertility and inspire new strategies for improving reproductive outcomes. We invite the scientific community to submit their work, with the aim of creating a high-impact collection that will serve as a key reference and stimulus for the future of male fertility research.

Sperm cryopreservation is essential for fertility preservation and assisted reproduction; however, post-thaw sperm quality varies markedly between individuals despite standardized protocols. This exploratory study investigated whether good and poor freezers differ in cellular, sub-cellular, and molecular features associated with cryoresistance. One ejaculate from each of 100 normozoospermic donors was assessed before cryopreservation and after thawing. Samples were classified after thawing as good freezers (GFs; n = 50) or poor freezers (PFs; n = 50) according to post-thaw motility performance, using total motility ≥ 42% and progressive motility ≥ 30% as thresholds. Sperm quality was evaluated using computer-assisted sperm analysis, membrane and acrosome integrity assays, mitochondrial membrane potential, capacitation-associated patterns, membrane lipid disorder and DNA/chromatin integrity tests. Post-thaw thermoresistance was assessed at 37 °C for 60 and 120 min. An exploratory Western blot panel was performed only on fresh pre-freeze samples from a selected subset of 4 GF and 4 PF samples. Cryopreservation reduced sperm quality in both groups; however, PF samples showed significantly greater declines in total and progressive motility, sperm viability, membrane and acrosome integrity, mitochondrial membrane potential and thermoresistance. Exploratory Western blot data showed GF-favoring patterns for proAKAP4, SPAG6, proACR and the proACR/ACR ratio, whereas PF samples showed relatively higher ACR abundance; these molecular findings require validation in larger cohorts. Our data indicate that human sperm cryoresistance is a coordinated multi-level phenomenon involving membrane, mitochondrial, acrosomal, chromatin and flagellar resilience. This study identifies candidate functional and molecular indicators associated with cryoresistance and supports future development of pre-freeze screening strategies rather than providing a validated predictive model or clinical cut-off values.
