According to the latest research as far as women are concerned the size of a man's penis is immaterial.
Women are far more interested in a man's personality and looks than the size of his penis, but men nevertheless often become anxious about whether their penis is big enough.
Penis anxiety apparently abounds in Britain where even when it was often found that while men often have a better body image, a better genital image and more sexual confidence if they have a large penis, women don't necessarily feel that bigger is better.
Dr. Kevan Wylie, of the Royal Hallamshire Hospital, in Sheffield, and Ian Eardley, of St. James' Hospital in Leeds, examined more than 50 international research projects on penile size and small penis syndrome completed since 1942.
The researchers found from 12 studies that measured the penises of 11,531 men, that on average, erect penises ranged from 5.5 to 6.2 inches in length and 4.7 to 5.1 inches in girth.
A survey then conducted of over 50,000 heterosexual men and women found that 66 percent of men said their penis was average-sized, 22 percent said large and 12 percent said small and while 85 percent of women were satisfied with their partner's penile size, but only 55 percent of men were satisfied with their penis size.
The urologists say having a micropenis is a totally different condition from having penis anxiety and they urge doctors not to laugh at these very real worries over an imaginary defect and say the review normalizes the situation and provides accurate information.
The researchers warn against plastic surgery techniques which promise to make a man's flaccid or erect penis larger as they are unproven and serious complications may ensue.
Wylie and Eardley say in such cases if education and counseling do not resolve the anxiety issue, psychotherapy is advisable for men whose obsession over penis size is interfering with their lives.
The review is published in the current issue of the urology journal BJU International.
