How Penis Erections Occur

How does a penis erection come into being and why do they sometimes happen spontaneously?

Erection is the medical term for that state of the penis when the two corpora cavernosa (two tubular receptacles) are filled with blood. This causes the penis to harden and lengthen to accommodate the extra blood.

Penile erection is the result of physical or mental sexual stimulation, but is also known to occur spontaneously, most commonly at night, during sleep. It is thought that erotic dreams may be the cause of this.

Erections can be caused by stimulation of the penis, or by the pressure of the bladder, when full. The exact cause of spontaneous erections is not known. The erection is crucial to having successful sexual intercourse and most other sexual activities for males.

From the physiological point of view, erection is caused by an increased flow of blood to the penis and by a strong decrease in the outflow. Muscles around the penis relax in order to allow the blood into the corpora cavernosa and corpus spongiosum, while contraction of other muscles reduces the outflow.

As the cavities within the penile shaft fill with blood, the penis expands in both length and girth. It also stiffens and rises to an almost perpendicular position (this varies from one man to another). but less so as a man ages.

Under certain conditions of stress, worry, anxiety, general ill health,or excessive alcohol intake, it may be impossible for a man to achieve a part erection, never mind a full erection. In which case it's advisable that the man seeks professional help through his doctor.

This is a common problem not only amongst older men and can be overcome to a certain extent with the right sort of advice and medication.

The inability to achieve or maintain an erection during foreplay or intercourse is known as impotence, or erectile dysfunction. This is a common condition amongst men of all ages, but gets progressively worse as a man gets older. However, it's a condition that is capable of being overcome by undergoing a program of penis enhancement.

A positive, firm erection is necessary for a couple to enjoy the full benefits of a loving, intimate relationship. Sexual stimulation between a man and his partner is as natural an act as the sun rising. It's an act that allows each person to express their emotions and feeling of love for each other.
