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.

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.

Associations Between Sperm DNA Fragmentation and Lifestyle Factors

Andrology, EarlyView.
ABSTRACT Background Sperm DNA fragmentation index (DFI) has been proposed as a supplementary biomarker to traditional semen parameters in the evaluation of male infertility. However, its determinants and clinical relevance remain unclear, particularly regarding modifiable lifestyle factors.

Prognostic factors for a favorable outcome after varicocele repair in adolescents and adults

Asian Journal of Andrology, 2016
The effect of varicocele repair on male fertility remains controversial. It would be helpful to determined which men would benefit most from varicocele repair, and target repair efforts at those individuals.

Father–Son Comparison of Reproductive Traits

Andrology, EarlyView.
ABSTRACT Background Little is known about the relative contribution of genetic and environmental factors on male reproductive function. Objectives We studied in a cross‐sectional setting, whether testicular function and genital size correlate in father–son pairs.
