The subject of the invention is interactive male underwear, intended to control the temperature of the surface of the skin of the male testicles, wherein reducing the temperature of the surface of the skin of the male testicles contributes to the treatment of male infertility in particular such as oligospermia, aspermia, asthenospermia, azoospermia, nekrospermia, normospermia and teratospermia. The male underwear comprises bearing element (EN) connected with the belt (LK) using connectors (LK), however at least one Peltier cell (8) of the skin temperature control system (UC) is mounted on a bearing element (EN). The bearing element (EN) is made of woven belt narrowed at the bottom in the capital U letter shape, however the upper part of the bearing element (EN) is connected directly with the belt (PA), and the D lower part is connected with the belt (PA) using connectors (LK).

A heat transfer device particularly structured for application of thermal therapy from a contact surface to internal structures of a human ear. A device may be passive (pre-cooled), active (thermoelectrically active), or include elements of both. A device may be structured to apply thermal treatment from a contact surface of a contact cavity only to a localized posterior area relative to the circumference of an ear. A device may include both of a contact cavity and a bulk cavity, with heat transfer media disposed in each cavity. Typically, a bulk cavity holds at least twice the media volume contained in a contact cavity. The cavities may be disposed in fluid communication, or separated by a barrier to permit only thermal communication therebetween. When a barrier is present, a device may include different heat transfer media in each cavity. One or more device may be associated with a pair of auditory headphones to dispose a contact surface in contact with desired portion(s) of a head.
