Testicular germ cell tumours (GCTs) are the most common malignancy among young men. Management of GCTs relies on the serum tumour markers α-fetoprotein, human chorionic gonadotropin, and lactate dehydrogenase, among other parameters. However, these tumour markers can only be detected at elevated levels in half of GCT patients. Circulating miR-371a-3p has emerged as a blood-based biomarker that can reliably detect macroscopic GCTs, aside from teratoma. Here we review the literature, describe the methodologies currently used to measure circulating miR-371a-3p, and discuss the following clinical scenarios in which miR-371a-3p may impact practice in the future: (1) men with an inconclusive small testicular mass; (2) response monitoring during chemotherapy; (3) postchemotherapy residual masses; and (4) follow-up after treatment with curative intent. PATIENT SUMMARY: We discuss the potential uses and promise, as well as current limitations, of a novel blood test that may improve care for men with testicular cancer.

The purpose of this study was to improve the quality of frozen-thawed canine spermatozoa through the optimization of glycerol concentration (GC) and freezing rate in the semen freezing protocol. Ejaculates from nine dogs were diluted with an extender containing 0%, 1.5%, 3%, 6%, or 9% glycerol.

Background: Parkinson's disease (PD) is the most common neurodegenerative movement disease. Human endogenous retroviruses (HERVs) are proviral remnants of ancient retroviral infection of germ cells that now constitute about 8% of the human genome. Under certain disease conditions, HERV genes are activated and partake in the disease process.

The TGF-β family ligand Nodal is an essential regulator of embryonic development, orchestrating key processes such as germ layer specification and body axis formation through activation of SMAD2/3-mediated signaling. Significantly, this activation requires the co-receptor Cripto-1. However, despite their essential roles in embryogenesis, the molecular mechanism through which Cripto-1 enables Nodal to activate the SMAD2/3 pathway has remained elusive.

Preimplantation embryonic development is orchestrated by dynamic changes in the proteome and transcriptome, regulated by mechanisms such as maternal-to-zygotic transition. Here, we employed label-free quantitative proteomics to comprehensively analyze proteome dynamics from germinal vesicle oocytes to blastocysts in mouse embryos. We identified 3490 proteins, including 715 consistently detected across all stages, revealing stage-specific changes in proteins associated with translation, protein modification, and mitochondrial metabolism.

Objective: Several male factors have been reported to play a role in recurrent pregnancy loss (RPL). The aim of this study is to explore the relationship between semen parameters, sperm DNA fragmentation index (DFI) and RPL.
Method: A total of 1485 participants were recruited from a university hospital between April 2020 and August 2022.
