Mechanisms of oligozoospermia: an oxidative stress perspective [PDF]
Systems Biology in Reproductive Medicine, 2014 Infertile patients presenting with poor semen concentration, motility, and morphology have significantly higher levels of reactive oxygen species (ROS). In this cross-sectional study, our goal was to: 1) determine how semen parameters such as concentration, motility, morphology, as well as ROS are altered in oligozoospermic men alone and those in ...
