1058-1067Short-term hyperthyroidism, induced by
daily administration of T3 (20μgl/100g body weight) for one,
three, and five days consecutively, modulates oxidative stress and antioxidant
defence parameters in mitochondrial and postmitochondrial fractions of testis in
adult rats. Alteration in antioxidant defences along with oxidative stress parameters
in testis by thyroid hormone was found to be associated with a decline in the
number of sperms and disturbances in histoarchitecture of seminiferous tubules in
the testes; the results indicated that induced hyperthyroid state altered testicular
physiology by influencing antioxidant defence system of testes
