Acceleration of Sperm Transit Time and Reduction of Sperm Reserves in the Epididymis of Rats Exposed to Sibutramine
(Amer Soc Andrology, Inc, 2011-11-01)
Sibutramine is a drug globally used for the treatment of obesity. The aim of this study was to investigate male reproductive disorders caused by sibutramine in adult rats. Wistar rats were treated for 28 consecutive days ...
Characterization of bovine transcripts preferentially expressed in testis and with a putative role in spermatogenesis
(Elsevier B.V., 2011-10-01)
Although the number of genes known to be associated with bovine spermatogenesis has increased in the past few years, regulation of this biological process remains poorly understood. Therefore, discovery of new male fertility ...
Age-related increase of reactive oxygen species in neat semen in healthy fertile men
(ELSEVIER SCIENCE INC, 2008)
OBJECTIVES The effects of advancing paternal age on the male reproductive system are well known, but its effects on fecundity remain controversial. Although oxidative stress is associated with poor semen quality and function, ...

X chromosome variants are associated with male fertility traits in two bovine populations
(2020-08-12)
BACKGROUND: Twenty-five phenotypes were measured as indicators of bull fertility (1099 Brahman and 1719 Tropical Composite bulls). Measurements included sperm morphology, scrotal circumference, and sperm chromatin phenotypes ...
