Regulating the inside temperature with thermal conduction has some restrictions as the dermal layers of the penis have separate blood supply from cavernous tissues so the skin as a conductor works very slowly to the direction or another. Therefor it is not so important in this case what the water temperature is . It can be +40C all the time as I consider it is safer option in the case of overheating with the ultrasound.
Using water only as a conductive medium may the aim with these solutions be then for heating with 1 to 3 MHz, or as I was pondering using long-waves for non-thermal solutions.
That was the real interest to know what actually is the 45 KHz penetrating depth. Low frequencies penetrating far deeper. For heating it is inefficient option as thermal energy absorbed in tissues with such frequencies is poor. So it is not for heating.
For non- thermal effects with low intensity to promote healing due frequencies of 30 ,40 or 45 kHz which has been suggested to promote increased production of IL-1, IL-8, vascular endothelial growth factor, fibrinoblast growth factor-b, and collagen, promotion of bone healing, and acceleration of thrombolysis at rates not seen with 1MHz and 3 MHz applications.
There will be attenuation of course both wave length and amplitude. From the soft tissue itself and the the acoustic impedance difference between skin and the water cause acoustic attenuation due intensity reflection coefficient .
But as the 1 MHz can penetrate more than 5cm with 50% of the energy has been absorbed at dept of 3- 5cm amplitude attenuating the deeper it penetrates. Frequency determines the penetration dept but by what equation?

When connective tissue is stretched within therapeutic temperatures ranging 102 to 110 F (38.9- 43.3 C), the amount of structural weakening produced by a given amount of tissue elongation varies inversely with the temperature. This is apparently related to the progressive increase in the viscous flow properties of the collagenous tissue when it is heated. (Warren et al (1971,1976)
