Abstract: A method of diminishing venous leakage to obviate male impotence by injecting fluid into penis implants so as to increase the size of these implants and correspondingly squeeze the flow passage of the leakage that is between the implants to reduce flow through the squeezed flow passage.

Abstract: Using latent heat of vaporization of a selected evaporative fluid, an abnormally elevated testicular temperature is effectively diminished so as to contribute to obviating male infertility due to poor semen quality. Moreover, the evaporative method employed, and the device using such method, are particularly appropriate in that the cooling effect is achieved over a prolonged period so as to facilitate achieving the desired medical result, whereas merely diminishing the testicular temperature for a short duration would not be medically effective.
