An erection clinically: penile erection or penile tumescence is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal or sexual attractionalthough erections can also be spontaneous.

Back to Sexual health. You have grown up together and shared many experiences, but how well do you really know your penis? If the penis is violently twisted when erect, it can break.
When men become sexually aroused, hormones, muscles, nerves, and blood vessels all work with one another to create an erection. Nerve signals, sent from the brain to the penis, stimulate muscles to relax. This, in turn, allows blood to flow to the tissue in the penis.
An erection problem occurs when a man cannot get or keep an erection that is firm enough for intercourse. You may not be able to get an erection at all. Or, you may lose the erection during intercourse before you are ready.
The Erection Hardness Score is a self-reporting measure that scores hardness on a 4 point scale to help men, their partners and doctors diagnose the causes of erectile dysfunction.

The ENDURANCE study evaluated the efficacy of vardenafil, a phosphodiesterase type 5 PDE5 inhibitor, in men with erectile dysfunction EDby measuring the duration of erection leading to successful intercourse using a stopwatch as the assessment instrument. This was a randomised, multicentre, double-blind, placebo-controlled, crossover study consisting of a 4-week treatment-free run-in phase after which patients were randomised to either fixed-dose vardenafil 10 mg or placebo to be administered 60 min prior to intercourse and entered the first of the two 4-week double-blind treatment periods, separated by a 1-week washout. Secondary efficacy end-points included SEP-2 and SEP-3 success rates, the erectile function domain of the International Index of Erectile Function, global assessment questionnaire, change from baseline in duration of erection and duration of erection not leading to successful intercourse.
If you notice that your morning erections are less frequent or less rigid, visit your GP, as it could be an early warning sign of heart disease or diabetes. After orgasm, every man goes through a recovery cycle, called the refractory period, which is when it is not possible to get another erection. This resolution stage can take anything from minutes to days and varies from man to man, generally extending as you get older. Your penis is sensitive to what is going on in your brain and your nervous system.
