Erectile Dysfunction (ED) is a sexual dysfunction characterised by the inability to get or maintain an erection firm enough to be able to achieve sexual penetration.
Having occasional erection failure is not necessarily a cause of concern. This condition is only considered a concern if satisfactory sexual performance has been impossible on a persistent number of occasions for a prolonged period of time.
Erectile Dysfunction used to be widely referred to as impotence. This was when the causes where not yet clearly understood, and successful treatments came into use. The term impotence is still being used, how ever it can be seen as pejorative. Impotence is derived from the Latin term impotentia coeundi, which describe a simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms such as erectile dysfunction (ED). Statistics say at least 40% of males suffer from ED at least occasionally. The Erection Process In order to understand erectile dysfunction better, we need to have a basic understanding of the erection process. Basically the erection equation is:
Libido (sexual desire) + Blood Flow = Erection
The erection process involves the central nervous system. It is initiated as a result of sexual arousal, where signals are transmitted from the brain to the nerves in the penis. Sexual arousal happens in response to touch, smell, auditory and visual stimuli, that trigger pathways in the brain. Resultantly information travels from the brain to the nerve to the nerve centres at the base of the spine, where primary nerve fibres connect to the penis and regulate blood flow during erections and afterwards.
Because of this stimulation, chemicals are released from the nerve endings in the penis that trigger a series of events that ultimately cause muscles to relax in the erection bodies of the penis. The smooth muscles control the flow of blood into the penis. Once the smooth muscles relaxes, blood flow dramatically increases and the erection bodies become full and rigid resulting in an erection.
A penile erection is the hydraulic effect of blood entering and being retained in sponge like bodies within the penis.
