Representative temperature curves during ultrasound or wet heat. A thermal couple was inserted down the long axis of the testis and another was placed in the coupling medium. Coupling medium was re-circulated at 37°C during ultrasound treatments and at 45°C for the wet heat control. The rotation frequency of the transducer correlated with temperature fluctuations at the site of the thermal couple. The wet heat control yielded a testis temperature profile similar to an ultrasound treated testis.
