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.

Andrology, EarlyView.ABSTRACT Sex chromosome aneuploidies represent a heterogeneous group of chromosomal conditions, in which phenotypic complexity generally increases with the number of supernumerary sex chromosomes. While Turner syndrome and sex chromosome trisomies are relatively well characterized, less is known about congenital malformations in sex chromosome ...

The CAG repeat within the androgen receptor gene and its relationship to cryptorchidism
International Brazilian Journal of Urology, 2006 PURPOSE: We examined the significance of the CAG repeat polymorphism in the pathogenesis of cryptorchidism. MATERIALS AND METHODS: Genomic deoxyribonucleic acid (DNA) was extracted from blood samples from 42 cryptorchid boys and from 31 non-cryptorchid ...

Overexpression of ubiquitin carboxyl-terminal hydrolase 1 (UCHL1) in boys with cryptorchidism
PLoS ONE, 2018 Background The ubiquitin-proteasome system regulate p53, caspase and Bcl-2 family proteins, and is crucial for the degradation of the defective germ cells in testes. Purpose: to evaluate the concentration of ubiquitin carboxyl-terminal hydrolase 1 (UCHL1)

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.
