Does acute spermatic cord torsion alter the microcirculation of the contralateral testis?
Acute spermatic cord torsion altered the microcirculation by increasing the amplitude of vasomotion and decreased total blood flow to the opposite testis. Because the hydraulic resistance of a blood vessel exhibiting vasomotion is always less than a vessel with the same average but static diameter, the observed microcirculatory changes may be an adaptive response to preserve local flow in the presence of decreased total flow. The long-term consequences of these changes in the microcirculation may affect testicular function and ultimately fertility.
These results suggest that a stable, well-consolidated negative self-concept is associated with prolonged depression and a poor response to psychosocial interventions.
