TL;DR: Evaluation of seminal ROS levels and extent of sperm DNA damage especially in an infertile male may help develop new therapeutic strategies and improve success of assisted reproductive techniques (ART).

TL;DR: Reactive oxygen species levels are significant higher in seminal ejaculates of healthy fertile men older than 40 years, suggesting that delayed fatherhood may reduce the chances of pregnancy as men become progressively less fertile with age.

TL;DR: In the fertile population, ROSs were positively correlated with leukocytes and negatively correlated with sperm count and motility and concentration and Seminal leukocyte levels below 1 x 10(6)/mL were associated with increased ROSs.

TL;DR: Although sperm quality was preserved in most of the patients with the exception of sperm morphology, patients treated with orchiectomy presented better motility and morphology compared with the detorsion group, and it was found that after torsion patients maintain late hormonal levels within the normal range.

TL;DR: A significant decline in semen volume, sperm motility and sperm morphology in patients over 45 years of age was observed and differences in semen parameters with regard to age, length of sexual abstinence, seasonality and coffee consumption were identified.
