This is an observational transversal cohort study in which we aim to analyze the Brazilian penis length and compare the penis size of the men self-declared as white (SDW) or black (SDB) skin color. Subjects were asked for self-declare according to their skin color, after that they have been invited to participate in a semi-structured interview so as to have their perception evaluated regarding their penis size and their self-esteem as well. Eventually, their penis length was measured with an anthropometric ruler...

Accurate data regarding the size of the erect penis is of great importance to several disciplines working with male patients, but little data exists on the best technique to measure penile length. While some previous small studies have suggested good correlation between stretched penile length, others have shown significant variability. Penile girth has been less well studied, and little data exist on the possible errors induced by differing observers and different techniques. Much of the published data report penile length measured from the penopubic skin junction-to-glans tip (STT) rather than pubic bone-to-tip (BTT)...

Imposex is the development of male sexual characteristics caused by the toxic effects of some chemicals that acts as an endocrinal disruptor. Antifouling paints contain these chemicals. Cartagena lacks studies to indicate the extent of imposex in its coastal waters. The aim of this study was to determine the prevalence of imposex in the gastropod Stramonita haemastoma in Cartagena, Colombia. Specimens were collected during 2013 from locations of high and low influence of port activity. Morphometric measurements and the frequency of the occurrence of imposex were registered...

The aim of this study was to compare imposex and butyltin compounds (BTs) data, collected before and after the organotin ban in 2008, in order to assess temporal and spatial variation of the phenomenon, the decline of BT contamination, and the effects on Hexaplex trunculus population in the coastal area of the northern Adriatic Sea, close to the Venice Lagoon. Both in marine and in lagoon sites, the results obtained in 2013-2015 showed a significant decline in the incidence of imposex in respect to those from the 2002 survey...

This article combines qualitative and quantitative textual approaches to the representation of penis size and sexual position of performers in 10 of the most visited gay pornography Web sites currently in operation. Specifically, in excess of 6,900 performer profiles sourced from 10 commercial Web sites are analyzed. Textual analysis of the profile descriptions is combined with a quantitative representation of disclosed penis size and sexual position, which is presented visually by two figures. The figures confirm that these sites generally market themselves as featuring penises that are extraordinarily large and find a sample-wide correlation between smaller penis sizes (5-6...

REVIEW
Jeffrey Campbell, Joshua Gillis
Penile elongation surgery is less commonly performed in the public sector, but involves a collaborative approach between urology and plastic surgery. Congenital and acquired micropenis are the classic surgical indications for penile elongation surgery. The goal of intervention in these patients is to restore a functional penis size in order to allow normal standing micturition, enable satisfying sexual intercourse and improve patient quality of life. Many men seeking elongation actually have normal length penises, but perceive themselves to be small, a psychologic condition termed 'penile dysmorphophobia'...

Leydig cell tumors (LCTs) are rare cord-stromal tumors that may occur in testis or ovaries and may produce androgens or estrogens. The majority has been found in men between the ages of 20 and 60 years. Adults with androgen-secreting LCTs are usually asymptomatic; feminizing syndromes may result from the production of estradiol or the peripheral aromatization of testosterone. In children, LCTs usually present between 5 and 10 years of age with isosexual precocious pseudopuberty or gynecomastia. We report 2 cases of LCT in prepubertal boys presenting with advanced unilateral pubarche and testicular volume asymmetry...

Research on gay and bisexual men's sexual position self-label (i.e., being a top, bottom, or versatile during anal sex) has revealed only independent snapshots of its development by focusing primarily on the influence of penis size. Moreover, the basic chronology of development of the sexual position self-label has barely been addressed. In response, we implemented a survey of 282 gay and bisexual men that measured demographics (including height and penis size), age of sexual recognitions, sexual position self-label, and attitudinal constructs suggested by previous literature as important (e...

Male genital satisfaction is an important aspect of psychosocial and sexual health. The Index of Male Genital Image (IMGI) is a new scale that measures perceptions of male genitalia. We aim to characterize genital satisfaction using the IMGI and correlate dissatisfaction with sexual activity. We conducted a nationally representative survey of non-institutionalized adults aged 18-65 years residing in the U.S. In total, 4198 men completed the survey and 3996 (95.2 %) completed the IMGI. Men reported highest satisfaction with the shape of their glans (64 %), lowest satisfaction with the length of their flaccid penis size (27 %), and neutrality with the scent of their genitals (44 %)...

INTRODUCTION: Recent studies have suggested that a smaller glans penis size may be associated with a higher likelihood of complications after hypospadias repair. Accurate identification of risk factors other than the well-understood variable of meatal location would allow development of better prognostic models and individualized risk stratification. OBJECTIVE: To test the hypothesis that a smaller width of the glans penis predicts adverse outcomes after hypospadias surgery...

Gay and bisexual (GB) men with prostate cancer (PCa) have been described as an "invisible diversity" in PCa research due to their lack of visibility, and absence of identification of their needs. This study examined the meaning and consequences of erectile dysfunction (ED) and other sexual changes in 124 GB men with PCa and 21 male partners, through an on-line survey. A sub-sample of 46 men with PCa and seven partners also took part in a one-to-one interview. ED was reported by 72 % of survey respondents, associated with reports of emotional distress, negative impact on gay identities, and feelings of sexual disqualification...

We explored self-discrepancy in men with body dysmorphic disorder (BDD) concerned about penis size, men without BDD but anxious about penis size, and controls. Men with BDD (n=26) were compared to those with small penis anxiety (SPA; n=31) and controls (n=33), objectively (by measuring) and investigating self-discrepancy: actual size, ideal size, and size they felt they should be according to self and other. Most men under-estimated their penis size, with the BDD group showing the greatest discrepancy between perceived and ideal size...

The present study explores how genital self-image may be related to considerations of surgically altering one's genitals and documents the wanted genital changes among young adults. Evidence of a nontrivial proportion of respondents (98 of 1,110) had seriously considered elective genital surgery. Regression models indicate that, for both men and women, identifying as heterosexual and reporting lower composite genital self-image scores results in higher odds of considering genital surgery. Additionally for men, feeling unsatisfied with penis size increased the odds...

UNLABELLED: We report the case of a 19-year-old boy, presenting several congenital malformations (facial dysmorphisms, cardiac and musculoskeletal abnormalities), mental retardation, recurrent respiratory infections during growth and delayed puberty. Although previously hospitalised in other medical centres, only psychological support had been recommended for this patient. In our department, genetic, biochemical/hormonal and ultrasound examinations were undertaken. The karyotype was 49,XXXXY, a rare aneuploidy with an incidence of 1/85 000-100 000, characterised by the presence of three extra X chromosomes in phenotypically male subjects...

INTRODUCTION: Studies have demonstrated high levels of satisfaction with penile prosthesis implantation (PPI). However, qualitative research exploring the experience of PPI through men's narratives is scarce. AIM: The main goals were to analyze (i) the level of sexual satisfaction (quantitatively), and (ii) the reasons for satisfaction and/or dissatisfaction with PPI (qualitatively). METHOD: Participants were 47 men with erectile dysfunction who underwent surgery between 2003 and 2012, placed by a single surgeon...

INTRODUCTION: Little is known about the sexual functioning and behavior of men anxious about the size of their penis and the means that they might use to try to alter the size of their penis. AIM: To compare sexual functioning and behavior in men with body dysmorphic disorder (BDD) concerning penis size and in men with small penis anxiety (SPA without BDD) and in a control group of men who do not have any concerns. METHODS: An opportunistic sample of 90 men from the community were recruited and divided into three groups: BDD (n = 26); SPA (n = 31) and controls (n = 33)...

Using the vas deferens sequence index (VDSI) and relative penis size index (RPSI) in dogwhelks (Nucella lapillus), imposex levels were assessed at 63 sites within 11 sea inlets during 2010/2011 and compared these with levels gathered since 1987. Sterile females (VDS>5.0) were found at 14 of the 63 sites and 47 sites (75%) met the EcoQO (VDSI<2.0). The absence of imposex in 'control' areas on the west coast is due to the lack of vessel paint applications or net dips with TBT being used as an active anti-fouling ingredient...

INTRODUCTION: Many men seek penile augmentation treatments-a standard tool for their counseling is to inform them of what is "normal." Although some studies suggest good correlation between stretched and erect penile length, those that have measured stretched and erect length simultaneously have shown significant variability. AIM: To assess the accuracy of differing penile measurements with multiple observers. METHODS: We recruited 201 adult men (mean age 49...
