1) Penile Length in the Flaccid and Erect States: Guidelines for Penile Augmentation. The Journal of Urology. Volume 156, Issue 3 , Pages 995-997, September 1996
We provide guidelines of penile length and circumference to assist in counseling patients considering penile augmentation.
MATERIALS AND METHODS
We prospectively measured flaccid and erect penile dimensions in 80 physically normal men before and after pharmacological erection.
Mean flaccid length was 8.8 cm., stretched length 12.4 cm. and erect length 12.9 cm. Neither patient age nor size of the flaccid penis accurately predicted erectile length. Stretched length most closely correlated with erect length.
Only men with a flaccid length of less than 4 cm., or a stretched or erect length of less than 7.5 cm [3 inches]. should be considered candidates for penile lengthening.
2) Penile size and the ‘small penis syndrome’. British Journal of Urology International. Volume 99, Issue 6, pages 1449–1455, June 2007
The male is often troubled by concerns that his penis is not large enough to satisfy his partner or himself. He is ashamed to have others view his penis, especially in the flaccid state. Such concerns might be unfounded in reality and might be a presentation of social anxiety or some other clinical problem, such as erectile dysfunction. Concern over the size of the penis, when such concern becomes excessive, might present as the ‘small penis syndrome’, an obsessive rumination with compulsive checking rituals, body dysmorphic disorder, or as part of a psychosis. However, it is often a worry that can be described as within the normal experience of many men. Various potential causal factors are considered. A thorough assessment, normalizing the worry and then exploring the treatment options in detail with the man, is essential to allow the matter to be consolidated satisfactorily within the male ego.
It is recommended that the initial approach to a man who has SPS is a thorough urological, psychosexual, psychological and psychiatric assessment that might involve more than one clinician. More research is required on the effects of race and age on penile length. Conservative approaches to therapy, based on education and self-awareness, as well as short-term structured psychotherapy (CBT) are often successful, and should be the initial interventions in all men. Of the physical treatments available, there is poorly documented evidence to support the use of penile extenders. More information is need on the outcomes with these devices. Similarly, there is emerging evidence about the place of surgery and there are now several reports suggesting that dividing the suspensory ligament can increase flaccid penile length. There are only limited data relating to operations designed to enhance penile circumference. While there are emerging data about the effect of surgical treatment on penile dimensions, there is much less information about the patients’ satisfaction with the outcome of surgery. Such assessments have only been reported occasionally, and in a situation where surgery is used cosmetically to treat a psychological condition, such outcomes are vital to assess the place of such surgery.
Penis-related concerns? Ask a doctor not a salesperson.
Many products ad procedures are offered on the internet. They are bogus! There is a surgical procedure but it simply releases the penis from the ligament holding it up onto their pubic bone. If that is released, the penis hangs down more and appears larger when soft. When it is erect there is a down side: the penis does not stand erect (like a good soldier) but may stick out to the side or down. That is not helpful when engaging in sex as the partner is not often off to the side.
Penis enlargement is rarely offered as it is rarely needed. Do not buy into the lies and pressure on the internet. The people selling these products have no interest in helping you feel better. In fact, they prey on people concerned about the size of the penis, flaming their anxiety. They do this in the hopes that they can sell them useless products for lots of money.
If you are worried about the size or function of your penis please talk to your doctor. It is most likely you are normal. The Predicktor app even provides a gauge where by men can see how their penis length compares to penises around the world. By doing this they learn that regardless of their length they are similar to millions of other men and not an outlier.
