What is an Erection?

An erection is a physiological event that occurs when increased blood flow to the penis causes the tissues within it to become engorged, resulting in an enlargement, hardness, and rigidity. This physiological process occurs in response to sexual arousal, and is essential for male orgasm and reproduction.

Physiological Components of an Erection

An erection occurs in the following sequence of physiological events:

  • Stimulation: Sexual arousal leads to nerve stimulation, which in turn triggers the release of hormones and chemicals, including nitric oxide and cyclic guanosine monophosphate (cGMP).
  • Relaxation: These hormones and chemicals cause the smooth muscles in the penis to relax, which in turn results in a higher amount of blood flowing in.
  • Engorgement: As the penis receives more and more blood, it ens up becoming engorged, leading to an erection.

Definition of Erection

In general terms, an erection is an enlargement, hardness, and rigidity of the penis, resulting from increased blood flow. It is a natural physiological process that occurs in response to sexual arousal, and is important for male sexual functioning and reproduction.
