Summary: This study compared the seminal plasma proteome of healthy fertile men with varicocele patients, identifying differentially expressed proteins associated with processes such as acrosome binding, protein folding, and oxidative stress. Validation confirmed abnormal expression levels of key proteins in varicocele patients. These findings suggest that aberrant seminal plasma protein expression could serve as an indicator of sperm pathology in varicocele patients.

Summary: This study identified differentially expressed proteins in seminal plasma of unilateral varicocele patients compared to fertile donors, with significant upregulation of ANXA2 and downregulation of KIF5B. The main upstream regulators of these proteins in unilateral varicocele group were androgen receptor, YB1, and NRF2. KIF5B and ANXA2 could potentially serve as biomarkers for infertility in unilateral varicocele patients.

Summary: This systematic review focused on the relationship between seminal plasma extracellular vesicles (sEVs) and male (in)fertility. After screening and eligibility assessment, nine studies were selected, which identified differences in sEV molecules (specifically proteins and small non-coding RNAs) between fertile and subfertile/infertile males. The content of sEVs was also found to be related to sperm fertilizing capacity, embryo development, and implantation.

Summary: Varicocele has been linked to male infertility, and improvements in sperm parameters post-varicocelectomy support this association. Cystatin C has been associated with cellular changes common in male infertility cases related to varicocele. This preliminary study found that seminal Cys C levels were significantly higher in infertile OAT men with varicocele compared to fertile men, and decreased post-operatively, suggesting a potential role of Cys C in varicocele-induced infertility.

Summary: This study aimed to investigate the effects of PUFA-derived metabolites in seminal plasma on male fertility and evaluate the potential of PUFA as a biomarker for normozoospermic male infertility. Semen samples were collected from 564 men, and the levels of PUFA-derived metabolites were analyzed. The results showed significant differences in the concentrations of certain metabolites between fertile and infertile men with normozoospermia and oligoasthenozoospermia. The metabolites 7(R)-MaR1, 11,12-DHET, 17(S)-HDHA, LXA5, and PGJ2 were identified as potential diagnostic biomarkers for infertility in normozoospermic men.

Summary: This study aimed to identify common differentially expressed genes (DEGs) that might serve as potential biomarkers for non-obstructive azoospermia (NOA) and overall male infertility. DEGs were explored across different datasets of transcriptomic profiling of testis from human patients with different causes of infertility/ impaired spermatogenesis and/or azoospermia using the gene expression omnibus (GEO) database. Twenty-five DEGs were shared between most of the datasets, and eight genes were found to be involved in overall spermatogenic processes or specific phases of spermatogenesis. The alteration in the expression of these genes may lead to impaired spermatogenesis and, ultimately, male infertility. Therefore, these genes can be used as potential biomarkers for the early detection of NOA.

Summary: Male infertility is a complex disorder that affects approximately 50% of male partners in infertile couples. Traditional diagnostic methods are inefficient, necessitating the use of more advanced techniques such as omics to study male infertility. Genetic alterations have been linked to male infertility, and analysis of transcriptomic data has identified genes involved in various biological processes related to male fertility. These findings have the potential to aid in the diagnosis and understanding of idiopathic male infertility.

Summary: Due to limited biological samples from returning space explorers, alternative models are needed to study spaceflight-related pathophysiology. This review provides an update on the hind-limb unloading model (HLU), which simulates microgravity in rodents. By removing gravitational load from the hind limbs, this model is widely used to study the effects of unloading on cardiovascular and musculoskeletal physiology. The advantages of HLU and its applications in understanding bedrest confinement and spaceflight effects are discussed.

Summary: Short linear motifs (SLiMs) are important for mediating protein-protein interactions, and viruses utilize these motifs to disrupt the host system. Through sequence analysis, four overriding SLiMs were identified in the SARS-CoV-2 Omicron variant, which may interfere with immune functions, cellular pathways, and contribute to viral infection and transmission. These SLiMs serve as potential therapeutic targets.

Summary: With the advancement in space exploration and the intention to establish an inhabitable human settlement on Mars, it is important to investigate the effects of exposure to space/microgravity and the associated radiations on procreation. This study systematically gathered and analyzed relevant information on the effects of spaceflight on male reproductive parameters and functions. Findings from the included articles indicated that exposure to microgravity and ionizing radiation can affect sperm motility, total sperm count, sperm DNA fragmentation, testosterone levels, and testicular weight. Countermeasure approaches are needed to manage or prevent these adverse effects.

Summary: A recent study analyzed blood samples from 14 astronauts and found 34 somatic nonsynonymous single nucleotide variants in 17 CH-driver genes. Interestingly, these genes seem to play essential roles in male reproduction. Another study reported changes in telomere length and gene regulation in an astronaut during a long duration stay on the International Space Station. More research is needed to understand the impact of spaceflight on gene sequence and male fertility.
