Nose Size Predicts Adult Erectile Penile Length

Previous studies have proved that nose size has a positive correlation with stretched penile length but stretched penile length does not fully represent erectile penile length. It is considered that the formation and growing ability of the penis is determined by the action of androgen in the fetal period and nose size has also been determined to some extent before birth. If the nose size is indeed related to the length of the penis, there must be a common mechanism behind it. To further confirm the relationship between nose size and penile length, especially erectile penile length, a correlation analysis was carried out by collecting general data and the data related to the nose, ears, and genitals of 377 males aged 20–56 years, including erectile penile length and erectile penile circumference. The results revealed that nose size had the highest correlation with erectile penile length (r = 0.507, p = 0 ) and flaccid penile length (r = 0.451, p = 0 ). Therefore, it is believed that nose size is an independent predictor of flaccid and erectile penile length, and the common factors that contribute to this correlation may appear in the fetal period.

Are there differences in stretched flaccid penile length versus erectile penile length in men with erectile dysfunction?

ABSTRACT Introduction Penile length measurement is an important tool in various clinical scenarios in andrology. It has been suggested that stretched flaccid penile length (SFPL) is an excellent surrogate for erect penile length (EPL). Objective We aimed to evaluate if the SFPL accurately reflects EPL. Methods Men with (i) Erectile Dysfunction (ED) without penile curvature (ii) undergoing penile duplex doppler ultrasound (DDUS) (iii) with a rigid erection were analyzed. SFPL and EPL were measured dorsally from the pubic symphysis to the coronal sulcus. Significant discrepancy was defined as a difference ≥1cm between the two measurements. We collected demographic and comorbidity data. Results 64 men were analyzed with a mean age of 59.4 ± 13.4 years. 37.5% of the patients reported 2 or more comorbidities, 11% had diabetes, 19% obstructive sleep apnea, 29% were current or former smokers, 54% had radical pelvic surgery, and 44% pelvic radiation. Mean SFPL was 10.8 ± 1.9 cm and mean EPL was 11.8 ± 1.8 cm, (p<0.001). 83% had EPL>SFPL. 47% of men had a significant discrepancy between the two measurements. No predictors of discrepancy were identified. Conclusions In our cohort of men with ED assessed during DDUS, there was a statistically significant difference between SFPL and EPL measurements. In almost half of the cases EPL was significantly longer than SFPL. SFPL is not a reasonable surrogate for erect penile length Disclosure Work supported by industry: no.

Prospective investigation of penile length with newborn male circumcision and second to fourth digit ratio

We prospectively investigated the relationship between newborn male circumcision (NMC) and second to fourth digit ratio with penile length. As participants for our study, we identified already circumcised young patients who visited our hospital for urological treatment. The age at which the circumcision had been done was assessed. The patients' height and weight were measured. Second to fourth digit ratio was calculated by measuring the second and fourth digit lengths. The flaccid and erectile penile lengths were measured from the base of the penis to the tip of the glans in standing position. A total of 248 patients were included in our study. In univariate analysis, height, second to fourth digit ratio, flaccid penile length, and age of circumcision were associated with erectile penile length. Among these variables, second to fourth digit ratio, flaccid penile length, and age of circumcision were significant predictive factors for erectile penile length in multivariate analysis. The subjects were divided into two groups, including 72 patients in the NMC group and 176 patients in the non-NMC group. No significant difference was found in height, weight, and second to fourth digit ratio between both groups. However, flaccid (p<0.001) and erectile (p=0.001) penile lengths were shorter in the NMC group than in the non-NMC group. Despite the small number of subjects, this study shows that NMC was associated with shorter penile length. Second to fourth digit ratio, flaccid penile length, and age of circumcision were also significant predictive factors for erectile penile length. Further multicentre studies with larger number of subjects and biochemical analyses are needed for potential clinical applicability.

The Investigation of Penile Length with Newborn Circumcision and Second to Fourth Digit Ratio

Objective: We retrospectively investigated the relationship between newborn male circumcision (NMC) and second to fourth digit ratio with penile length in young adult. Design and Method: We evaluated that the patients who had history of the circumcision at past visited our hospital for urological treatment. The age at which the circumcision had been done was assessed. The patients’ heights and weights were measured. Second to fourth digit ratio was calculated by measuring the second and fourth digit lengths. The flaccid and erectile penile lengths were measured from the base of the penis to the tip of the glans in standing position. Results: A total of 248 patients finished our study. The subjects were divided into two groups, including 72 patients in the NMC group, and 176 patients in the non-NMC group. In univariate analysis, height, second to fourth digit ratio, flaccid penile length and age of circumcision were associated with erectile penile length. Flaccid (p&lt;0.001) and erectile (p=0.001) penile lengths were shorter in the NMC group than in the non-NMC group. Among these variables, second to fourth digit ratio, flaccid penile length and age of circumcision were a significant predictive factor for erectile penile length in multivariate analysis. Conclusions: Second to fourth digit ratio, flaccid penile length and the age of circumcision were significant predictive factors for erectile penile length. Furthermore, penile lengths were shorter in the NMC group than in the non-NMC group.

Surgical treatment of Peyronie's disease with autologous tunica vaginalis of testis.

BackgroundTo investigate the feasibility and safety of surgical treatment for Peyronie’s disease (PD) by excising and repairing plaque using autologous tunica vaginalis of testis.MethodsFrom March 2007 to December 2012, total 19 patients with PD underwent surgical treatment at our center. All patients had significant phallocampsis during erection. All patients complained of decreased sexual function. During the operation, the fibrotic plaque was excised and neurovascular bundle (NVB) was spared. A size-matching autologous tunica vaginalis of testis was harvested as the graft and patched to the defect. All patients received follow up every 3 months in the first year and 6 months in the following years. Data on sexual function before and after the operation was collected and compared.ResultsAll operations were completed successfully without serious complications. The mean operative time was 74 min. The mean size of excised plaque was 3.0 cm2. Postoperative pathological studies revealed the fibroplastic hyperplasia of excised tissue. All patients had satisfactory correction of penile appearance. The erectile penile length between pre- and post-operation didn’t show significant difference. Postoperative intercourse satisfaction and overall satisfaction measured by IIEF-5 were significant improved.ConclusionsOur surgical treatment is feasible and safe for patients with PD. It can effectively improve the penile cosmetic appearance and patients’ intercourse/overall satisfaction on sexual life.
