The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

Andrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.
