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.

Role of ANO1‐Expressing PDGFRα+ Smooth Muscle Cells in Generating Spontaneous Phasic Contractions of the Rodent Epididymis

Andrology, EarlyView.
ABSTRACT Background Spontaneous phasic contractions (SPCs) in the epididymal duct play an important role in transport and maturation of sperm. In proximal cauda of the rat epididymis, platelet‐derived growth factor receptor α (PDGFRα)‐positive smooth muscle cells (SMCs) generate ANO1 Ca2+‐activated chloride channels (CaCCs)‐dependent spontaneous ...

Obesity Is an Independent Risk Factor for Oligozoospermia, With Co‐Existing Hyperglycemia Exacerbating Risks of Asthenozoospermia and Elevated Sperm DNA Fragmentation

Andrology, EarlyView.
ABSTRACT Background Metabolic health plays a critical role in maintaining male fertility and may influence offspring health. Therefore, it is necessary to incorporate metabolic indicators into the clinical assessment of male fertility. However, the relationships between different metabolic abnormalities and semen quality remain incompletely understood.

Prevalence of Spermatozoa in the Ejaculate of Adolescents With Klinefelter Syndrome: Implications for Fertility Counseling

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is the most common genetic cause of male infertility and is associated with nonobstructive azoospermia. Advances in surgical sperm retrieval techniques have enabled biological fatherhood in a subset of men with KS.

Occupational Physical Activity Is Negatively Associated With Semen Quality

Andrology, EarlyView.
ABSTRACT Background Lifestyle factors have been associated with semen quality and have been implicated in the reported global decline in semen parameters. Moderate physical activity has been linked to improved semen quality; however, the association between occupational physical activity and semen quality is limited.
