Nose size indicates maximum penile length

Background In a previous report, we investigated whether the size of male genitalia similarly exposed to serum testosterone during aging could change with age and found that penile length almost stopped increasing during adolescence and decreased in older males. In this report, to determine what factors other than age are related to penile length, we performed a multivariate analysis of the relationships between stretched penile length (SPL) and other measurements of genital organs, nose size, height and body weight in 126 adults in their 30s–50s. Results The most highly correlated factor with SPL was flaccid penile length (r = 0.565, P < 0.0001). The next highest correlation was nose size (r = 0.564, P < 0.0001). The penile stretched rate correlated with FPL (r = − 0.690, P < 0.0001) but not with SPL or penile circumference. Conclusions The fact that nose size is related to SPL indicates that penile length may not be determined by age, height or body weight but has already been determined before birth.

THE USE OF RIGISCAN® EXAMINATION IN DIAGNOSING PATIENTS WITH ERECTILE DYSFUNCTION IN JAKARTA

Objective: The aim of this study is to describe the characteristic of patients with Erectile Dysfunction (ED) and results of Nocturnal penile tumescence and rigidity (NPTR) based on Rigiscan® examination in patients with ED in Jakarta. Material & Methods: Descriptive-prospective study of patients with ED in Cipto Mangunkusumo Referral Hospital, Bunda General Hospital Jakarta, and ASRI-Siloam Urology Hospital are recorded during 2015. Patients’ age (in years), marital status (yes/no), duration of ED (in months), and International Index of Erectile Function-5 (IIEF-5) were recorded. NPTR examination were performed while patients were sleeping. Number of events, duration of each event (in minutes) as well as the rigidity (in percentage) and tumescence (in cm) were recorded. The elevation of tip and base penile circumference (in cm) during erection were also noted. Results: There were 34 patients who agreed to perform NPTR test. Most patients were married with the average age of 40.94 ± 10.81 years old. The duration of ED were varied from 5 to 96 months with average duration of 33.7 ± 44.34 months and IIEF-5 score was 6.38 ± 5.14. In general number of erections was 4 ± 3 with 23.4% of them had normal erection. The comparison between organic and psychogenic ED showed that the increment of circumference was significantly less in organic ED patients. Other parameters showed insignificant difference in statistical results. Conclusion: NPTR examination is an objective, effective, and easy-to-use measurement in order to differentiate between organic and psychogenic ED. One third of patients who complained with ED suffered from psychogenic ED and needed referral to other specialists.

A mathematical model to predict the loss of length in patients undergoing plication corporoplasty for Peyronie’s disease

Introduction: Peyronie’s disease affects three to nine out of 100 men and can have significant emotional and sexual effects on patients and their partners. Treatment options vary but once the disease becomes quiescent they are predominantly surgical. The type of surgery adopted is dependent on the degree of angulation although no single procedure is without its disadvantages. Plication corporoplasty is one approach but patients experience and often complain of loss of penile length. We set out to devise a mathematical model that would allow us to predict the loss of length based on erect penile dimensions. Methods: By considering the bend in the erect penis as an arc, utilising the degree of curvature and the penile circumference at maximum angulation, we have been able to derive a simple equation using parameters that are easily obtained in the clinic. Results: Where L=length lost, C=circumference at point of curvature, Y=angle of curvature as measured by a goniometer: L = CY/180. We have then been able to create a quick reference table based on the average penile circumference (12–13 cm±5 cm). Conclusion: This formula provides a more scientific and accurate means to predict potential loss of penile length in patients undergoing plication corporoplasty. Although we recognise that applying a rigid mathematical model to a biological non-uniform pathology creates inaccuracies this is somewhat better than ‘by sight’ estimates, and will allow more informed counselling and consent for patients. As far as we are aware this is the first attempt to create a mathematical model to aid counselling for plication corporoplasty.

Does penis size influence condom slippage and breakage?

This study examined the effect of penis dimensions on the probability of complete condom slippage and condom breakage in actual use. Men were recruited through advertising, used the condoms supplied and completed a diary sheet for each condom used. A total of 3658 condoms were used by 184 men of which 1.34 broke and 2.05 slipped off. No significant effect was demonstrated for penile dimensions on the probability of complete condom slippage. However, condom breakage was strongly associated with penile circumference. These findings suggest that condom manufacturers may need to increase the range of condom sizes available, or some aspects of their performance, in order to ensure that condoms meet the needs of all men without unduly exposing them to risk.

Assessment and Treatment of Sex Offenders: The Prince of Wales Programme

The treatment programme for sex offenders at the Prince of Wales Hospital, Sydney, is described. Penile circumference assessment is not used as there is no evidence it provides a valid measure of individuals' paedophile or rapist tendencies. Sex offenders' self-reports remain the major source of information in their assessment. The development of the two major techniques used -imaginal desensitization and short-term medroxyprogesterone — is outlined. About 80% of subjects can be expected to show a good response to one or other of these therapies. Of those who do not, most respond to the alternative or aversive therapy. Adolescent offenders appear to require more intensive treatment. Results appear comparable with those of more intensive programmes in use overseas.
