Erectile dysfunction, ED, is a sexual dysfunction that affects the reproductive systems of both men and women. By definition according to National Institute of Health consensus Development Panel on impotence (1993), in Males, it is a sexual dysfunction characterized with the inability to develop or maintain an erection of the penis sufficient for satisfactory sexual performance. It is also known as Male impotence or Baby D syndrome, while in women, according to American Psychiatric Association (1994), it is characterized with the persistent or recurrent inability to attain, or maintain until completion of the sexual activity, an adequate Lubrication- Swelling response that otherwise is present during female sexual arousal and sexual activity is thus prevented. Hence, it is called Women impotence or female erectile dysfunction. The word impotence may also be used to describe other problems that may interfere with sexual intercourse and reproduction, such as lack of Sexual Desire and problems with ejaculation or orgasm. Using the term “erectile dysfunction,” however makes it clear that those other problems are not involved (NIH, 2005).
An erection occurs as a hydraulic effect due to blood entering and being retained in sponge-like bodies within the penis and clitoris. The process is most often than not initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the pelvis.Erectile dysfunction is, therefore indicated when an erection is consistently difficult or impossible to produce, despite arousal (Laumann et al., 1999).
