Scholarcy highlights

  • There is growing concern on sperm quality since documentation and research exists stating a declining trend in semen quality over the past 50 years onwards
  • The present study shows that there are diVerences in semen and hormone values of physically active subjects and sedentary subjects
  • We have previously described how exercise can be detrimental for semen quality and hormones, and how diVerences in semen proWles exist due to inherent characteristics and requirements of the sport modality and level being practiced
  • The exclusion criteria were any factors that could interfere with normality, while the inclusion criteria were a minimum practice of 2–4 h/w, for at least three diVerent days, and a maximum oxygen uptake ̧ 40 ml min¡1 kg¡1 for the PA group, and not practicing any physical activity and a VO2max < 40 ml min¡1 kg¡1 for SE
  • Statistical diVerences were found for several semen parameters: type “b”, “d” and “a + b” velocities, and percentage of normal forms; of those, the most clinically important diVerences were in type “a + b” as well as in percentage of normal forms
  • It has been previously shown that intense endurance exercise provokes a diminution in both hormones and semen parameters when subjecting physically active subjects to such physiological stress
  • Some studies have argued that the eVect on the reactive oxygen species-antioxidant system relation is sports speciWc, observing diVerences in the activity of various antioxidant enzymes such as catalase
