Physiotherapy loop sex toys for men Physiotherapy loop for delaying time vs. enlarging the penis is developed by taking muscle pump-action principle and the cyclical activities theory for penis cavernous body EMG for scientific basis. It plays a role as enlarging penis and delaying time.In order to enlarge penis, etc. having simultaneous effects on the testis, the roots of the penis, penis Central, the corona part of the glans and so on through four physiotherapy loop which can be adjusted in size. Developed by basing on muscle pump-action principle, that is, low-frequency current causing muscle to contract or relax. When the low-frequency current signal is blocked, muscle is on the state of relaxation, and then large scale of blood imports; when connected to low-frequency current, which causes nerve act, muscle is on the stage of access, then the blood with the metabolism exports. This cycle of actions can promote blood running smoothly, thereby accelerating muscle cells to grow and to become full of flexibility and toughness, increasing muscle flexibility, and thus enlarge the penis.When the current pulse comes to the peak, the smooth muscle relaxes, the cavernous is full of blood, the cavernous has significant reduction in blood outflow, thereby penile erects, this process is controlled by the autonomic; when pulse is in the current trough, the smooth muscle of cavernous contracts when the sympathetic nervous excites. Through these contractions of regulation, can be controlled, alternating, PC muscle, cavernous smooth muscle is full of vitality in the short term. Through training and conditioning nerve center, reducing the sensitivity of the nerve to raise the threshold ejaculation, delaying the extension of life, thereby completely eliminating the symptoms of premature ejaculation caused by a variety of reasons. Product effect:Quickly promoting penis enlargement, extending congestion, regulating nerve sensitivity, eliminating premature ejaculation;Host Model:Main parameters: SM-69 Voltage: DC 3V Battery models: AAA x 2 (1.5V)Pulsed output power: MAX 100V / 20mAPulse frequency: 2-100 HzPulse mode: 10 stalls strength, five kinds of rhythm
