Understanding the Physiology of Erectile Dysfunction



Erectile Dysfunction We all know that erection is a rather complex process than previously thought of. This process is so complex that if something goes wrong along the way, erection may be impossible to achieve. This is why it is important for men to learn of the physiology of erection. The basic understanding of this complex process is a key for most men to enjoy pleasurable sex. It also gives them some knowledge especially for treatment in cases where erection is not achieved.

Here are the processes and the effects on the body parts during an erectile dysfunction:

  • The signal always starts from the brain. Whether erection will be achieved or not depends largely on the ability of the brain to perceive the signs that will trigger the penis to become erect. In particular, the hypothalamus, the cerebral cortex, and the limbic system have all been known to play a large part in men attaining erection. If one of these parts does not play its role, the only probable result is failure to achieve an erection.
  • Because there are many parts in the body that are related to the erectile process, any time there are signals for erections, there are also signals whose main task is to inhibit it. This is why men have the ability to hold off erection by channeling thoughts elsewhere, although such does not actually constitute erectile dysfunction.
  • Assuming that the brain parts necessary for erection are working well and working in harmony with each other, what happens next is the muscles in the penis, especially the corpora cavernosa, will begin releasing suprasacral fluids that will prepare the arterial muscles for erection by making them smoother and relaxed. However, in the case of an erectile dysfunction, the brain often interprets this as nothing more than a random excess production of the fluid so it does not see any reason to prepare the arteries for erection. When this is the case, the amount of blood that flows into the arteries is not enough to cause erection. In fact, the pressure and level of blood flow in such situation is not significantly higher than the level required for sustenance such as for the delivery of nutrients into the penile area.
  • Another reason why erectile dysfunction occurs is when there is an elevated release of catecholamine fluids whose effect is to counter the erection-causing effect of the increased blood flow. This causes the smooth muscles in the penis to become "excited", which restricts the expansion of the arteries, thereby limiting the amount of blood they can handle.
  • On the other hand, if the sympathetic nerves do not cooperate, erectile dysfunction is a possible result. This happens when the sympathetic nerves infuses epinephrine. Epinephrine is a type of enzyme whose effect is to constrict the penis resulting to failure of achieving erection. In some cases, epinephrine is infused a short while after erection is achieved, which leads to a situation wherein a man only has a short-lived erection.
