How Does An Erection Happen?

Getting an erection is one an impressive functions of the male body that can be observed on a regular basis without having to use any devices. While this process may appear fairly straightforward and effortless, it is anything but that. When discussing the erection process as it pertains to the penis or even the clitoris, it's much the same between the two and is just as complicated since it's guided by either the autonomic or central nervous systems. Which one depends on the type of stimulation encountered.

The most commonplace types of stimulation men get is based on imagined, visual, olfactory, tactile or auditory stimuli. This stimulus tells the cerebral cortex to start the process of erection. Located in the sacral and lumbar areas of the spinal cord, the erectile centers make the pubic area nerves release nitric oxide. Nitric oxide is a molecular chemical that's used by all mammals to convey information between cells.

At this point, the arteries which supply the penis with blood dilate and allow more blood than usual to enter the Corpora Cavernosa of the penis. The Corpora Cavernosa is two sponge-like tissues that expand in size to hold as much blood as possible. Just below the Corpora Cavernosa is a tubular structure called the Corpus Spongiosum. This structure, thru which both semen and urine pass, also expands slightly as it fills with blood but not as much as the Corpora Cavernosa.

Once there's enough blood in the penis, the arteries will contract so that there will then be the normal amount of blood flow. This prevents the blood that's already inside the penis from being able to leave the area. This entire process is managed by the autonomic nervous system (ANS) with little input from the central nervous system. Once the stimulation has stopped, the ANS will then make the arteries contract which forces blood back out of the penis.

Even though the cerebral cortex isn't involved in every single type of stimulation that can cause an erection, it can certainly put a stop to an erection if it determines that the situation requires it. That's why both men and women need to avoid the things that could "kill the mood" and thus turn them off.
