The aim of this prospective study was to identify clinical and engineering parameters of the flaccid penis for prediction of penile size during erection. [] Key Method Dorsal and ventral penile lengths, as well as base and tip circumferences were measured in flaccid states, gently stretched states and at full erection resulting from intracavernosal injection of prostaglandin E1 in 55 patients.
Comparing penile measurements in normal and erectile dysfunction subjects.
The average of fully stretched penile length in normal potent men is 12.9 cm, whereas the patients with ED tend to have significantly shorter penises.
Penile length and circumference: an Indian study
There are significant differences in the mean penile length and circumference of Indian sample compared to the data reported from other countries, andPenile dimensions are found to be correlated with anthropometric parameters.
Penile Morphometrics and Erectile Function in Healthy Portuguese Men
Evidence that penile morphometrics interferes with erectile function is provided and this is an important source of information for professionals working in the male sexual health field.
Penile length is normal in most men seeking penile lengthening procedures
It is shown that most men who seek penile lengthening surgery overestimate ‘normal’ penile length and most found the use of a nomgram to show them how they compared with other men helpful.
Analysis of the Interobserver Variability in Penile Length Assessment.
In this large, multicenter, multi-observer study of penis size, flaccid measurements underestimated erect size and it seems likely that there is significant interobserver variability.
Patient Selection and Counseling
The purpose of this chapter is to introduce the measurements of penile dimension, summarize the available literature on penile size, discuss conditions that contribute to penile shortening, and
A prospective evaluation of penile measures and glans penis sensory changes after penile prosthetic surgery
A statistically significant increase in penile length and girth after IPP placement without significant changes in sensory conduction is observed.


Sonographic measurement of penile erectile volume
A comparison of the increase of penile erectile parameters after PGE1 injection between the good and poor response groups of patients revealed a significantly greater increase of the diameter of corpus cavernosum in the good response patients.
Clinical study of the longitudinal deformation of the flaccid penis and of its variations with aging.
The study shows that the flaccid penis is deformable, extensible and elastic in its longitudinal axis, and the analysis of the variations of these biomechanical properties with aging shows a significant decrease.
Engineering analysis of penile hemodynamic and structural-dynamic relationships: Part II—Clinical implications of penile buckling
Purpose: Penile buckling force was analytically described in terms of its constituents. In addition, theoretically-derived buckling force data were compared to clinically measured data and the
Engineering analysis of penile hemodynamic and structural-dynamic relationships: Part I—Clinical implications of penile tissue mechanical properties
Enabling penile volume to be derived as a function of tissue mechanical characteristics and pressure, allows for penile rigidity to be expressed as a result of pressure, geometry and tissue qualities.
Assessment and modeling of the physical components of human corporovenous function.
The proposed analog model can be used to interpret and characterize clinical penile hemodynamic data and may provide guidelines for more successful management of patients with erectile dysfunction.
