The Facts
Understanding Erectile Dysfunction and Libido
Erectile Dysfunction, (ED) is a common problem-much more so than you may think-with numbers on the rise. Presently, one in 10 men in the world are reported to have erectile dysfunction. These numbers are thought to be a low estimate because in the past men have generally reluctant to talk about this issue. As awareness increases, so do the number of men who seek treatment.According to WebMD, ED is the inability to achieve and sustain an erection suitable for sexual intercourse. This condition is not considered normal at any age and is different from other problems that interfere with sexual intercourse, such as lack of sexual desire and problems with ejaculation and orgasm.
The Mayo Clinic adds that things are changing with knowledge. They state that ED, formerly called impotence, was considered a psychological issue or a natural consequence of growing older. These attitudes have changed in recent years. It's now known that erectile dysfunction is more often caused by physical problems than by psychological ones, and that many men have normal erections into their 80s. Although erectile dysfunction is more common in older men, this common problem can occur at any age. At one time, doctors thought erectile dysfunction was primarily caused by psychological issues. But this isn't true. While thoughts and emotions always play a role in getting an erection, erectile dysfunction is usually caused by something physical.
Anatomy of an Erection
The penis is the male sexual organ. It contains:
Two cylinder-shaped chambers called the corpora cavernosa, which run the length of the penis and contain a maze of blood vessels and sinuses (cavities). The urethra, the channel in which urine and sperm flow, which runs along the underside of the corpora cavernosa. Erectile tissue, which is contained within the corpora cavernosa above the urethra, two main arteries and several veins and nerves. The shaft, the longest part of the penis. The head (glans), located at the end of the shaft. The meatus, the opening at the tip of the head where urine and semen are discharged. 
Libido
Libido is sexual drive and sexual desire. Basically, it is one’s urge to engage in sexual activity. Many couples suffer from low libido, causing upsetting relationship problems. According to Barry and Emily McCarthy, renowned authors on the subject, "inhibited desire is the most common sexual dysfunction, effecting one in three couples. Desire problems drain intimacy and good feelings from the relationship.One in five married couples has a non-sexual marriage (being sexual less than ten times a year). Three in ten non-married-couples who have been together longer than two years have a non-sexual relationship." Historically, men who have low libido often avoid talking about the subject altogether, resulting in profound effects on their sex life. As with ED, low sex drive is a common problem, and as we gain more knowledge and insight into it, we can provide treatment.
