The basis of treatment for advanced germ cell tumors is chemotherapy and surgical resection of residual disease. Surgery has maintained its role in staging and therapeutic management. Despite these advances, much of the outcomes depend on proper patient selection. Complete removal of all post-chemotherapy residual masses remains the standard of care in the treatment of advanced nonseminomatous germ cell tumors both within and outside of the retroperitoneum.

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.
