For men with ed who don't tolerate or respond to other treatments, a penile prosthesis offers an effective yet more invasive alternative, requiring surgery. Prostheses come in either a semirigid form or as an inflatable device. Most men prefer the inflatable prosthesis because it permits a more natural appearance when the penis is flaccid. Patients are under general anesthesia (completely asleep) for surgical placement of the prosthesis. An incision is made in the skin at the penis-scrotum junction.
The spongy tissue of the penis is exposed and dilated; the prosthesis is sized; and then it's placed inside the erectile tissue.
Toggle accordion item the cylinders of the implant, which are inserted into the erectile chamber of penis act as a reservoir that hold the saline next to the bladder. When the patient pumps the device using the button that has been inserted into the scrotum, the cylinders will fill up with the saline from the reservoir, giving the patient a normal erection. To return to the flaccid state, the patient simply presses the button once more and everything returns to normal.
Α-adrenergically mediated contraction of cavernosal and vascular smooth muscle limits blood flow to the penis and maintain the usual flaccid state. An erection occurs when erotic stimuli, received via any of the five senses and processed in the hypothalamus, results in inhibition of sympathetic tone and release of nitric oxide (no) from nonadrenergic, noncholinergic (nanc) nerves and endothelial cells of the arterioles in the penis ( 5 ). No activates guanyl cyclase, thereby generating cyclic guanosine monophosphate (cgmp). Cgmp decreases calcium uptake into vascular and cavernosal smooth muscle and induces relaxation. Smooth muscle relaxation permits engorgement of cavernosal sinusoids with blood and the development of an erection.
