Is physical exercise at high altitude associated with a testicular dysfunction leading to reduced sperm concentration but healthy sperm quality?
Physical exercise at HA is associated with a testicular dysfunction leading to a reduced sperm concentration probably through an altered spermiation. The improved body composition after physical exercise might explain the higher T levels observed after the expedition.
The elevated serum concentrations of cTnI indicate that myocardial cell death is occurring in meningococcal septicemia. The relationship between cTnI and markers of myocardial function suggest that the cell death may have a role in the pathogenesis of myocardial dysfunction in meningococcal septicemia. Elucidation of the mechanism responsible for myocardial injury may lead to the development of therapeutic interventions to prevent or limit this cardiac damage.
