Beyond muscles: unexplored parts of men's body image

Effects of perspective taking on attention bias to body-related information among junior high school students with body image disturbance

Using lexical judgment tasks, the present study explored whether perspective taking affected attention bias to body-related information among junior high school students with body image disturbance. Experiment 1 examined the junior high school students' attention bias to body schema-related words; the results showed the body image disturbance group responded significantly more quickly to negative body schema-related words than positive words, whereas the control group did not show a significant difference between positive and negative words. In Experiment 2, participants were asked to judge whether the positive or negative body schema-related words were suitable to describe themselves, when adopting their own perspective or that of another person. The results showed that reaction times to negative words were significantly shorter than to positive words when adopting a self-perspective. When taking another's perspective, there was no significant difference of reaction time between positive and negative words. This result demonstrated that perspective taking reduced attention bias to negative body schema-related information among junior high school students with body image disturbance. The present research suggests that guiding adolescents to view themselves from different perspectives can help them form a more accurate and objective body image.

Is size in the eye of the beholder? Visual estimation of penis size among transgender and cisgender people and implications for genital gender-affirming surgery and sexual medicine

BACKGROUND

Transgender men (TM) seeking gender-affirming phalloplasty and transgender women (TW) seeking vaginoplasty and desiring insertive intercourse must consider penis size. Evidence has shown that, at least among cisgender men (CM), penile dimensions tend to be poorly estimated. In transgender patients desiring gender-affirming surgery, inaccuracy in estimation of penis dimensions may lead to unnecessary morbidity: for TW, trauma to the neovagina; for TM with excess girth, an inability to insert. Studies on the accuracy with which transgender and cisgender patients estimate penis size are limited.

AIM

To assess the degree of accuracy with which CM and CW, as well as TM and TW, visually estimate the size of the human penis, including length, width, and girth.

METHODS

There were 142 participants included (25 TM, 47 TW, 30 CM, and 40 CW; net mean ± SD age, 36.6 ± 11.2 years). Participants were shown these models and asked to estimate length, width, and midshaft girth by visual inspection of 6 realistic models of a penis and scrotum of varying lengths and widths. We evaluated the accuracy of the visual measurements by comparing mean perceived dimensions with the actual dimensions of each model.

OUTCOMES

We used a multivariate model of all 3 bias dimensions to test for differences in average bias among gender groups (CM, CW, TM, and TW).

RESULTS

TM significantly overestimated length across the longest models. TW significantly overestimated length in the longer 3 models. All groups except for TM significantly underestimated girth in at least 1 model. No groups significantly underestimated width. CM, CW, and TM significantly overestimated width in all 6 models.

CLINICAL IMPLICATIONS

When transgender patients use numbers to express penis size (either in neophallus or vaginal depth based on perceived partner size), the result is likely to be larger than expected. Use of realistic penis models as a decision-making tool may help manage patient expectations and surgery decision making preoperatively and improve postoperative patient satisfaction and safety.

STRENGTHS AND LIMITATIONS

To our knowledge, this is the first study to assess visual estimation in penis size in TM and CM, as well as TW and CW. The penile models in our study were shown side by side and in the flaccid state despite having dimensions more consistent with an erect penis, which may have influenced estimations across all dimensions.

CONCLUSION

Men and women (cisgender and transgender) tend to significantly overestimate penis length and width.

The Efficacy of Injection Penile Girth Enhancement as an Option for Small Penis Syndrome Management

BACKGROUND

In recent years aesthetic injection techniques with soft tissue fillers have become popular worldwide due to their effectiveness, safety, and low cost. There is no standard approach to the management and follow-up of patients seeking penile enlargement procedures described in the literature, and the surgical penile enlargement methods are controversial.

OBJECTIVES

The goals of this study were to assess the effect of injection penile girth enlargement on sexual relationship satisfaction, confidence, and self-esteem, and to evaluate the clinical efficacy and safety of this procedure for the management of men with small penis syndrome (SPS).

METHODS

This was a single-center, clinical case series study executed from January 2019 to February 2021, which involved 148 men who were unsatisfied with the shape of their normal-size penises and requested penis girth correction.

RESULTS

A total of 132 patients completed full treatment and follow-up. Mean girth enlargement was 1.7 ± 0.32 cm for the midshaft and 1.5 ± 0.32 cm for the glans of the penis. Satisfaction with sexual life improved. Mean scores increased by 17.9 ± 3.04 points for sexual relationship satisfaction and by 12.2 ± 3.17 points for confidence. The mean score for self-esteem increased by 8 ± 2.8 and by 4.3 ± 0.97 points for overall relationship satisfaction.

CONCLUSIONS

Penile enlargement with hyaluronic acid injection positively affects sexual relationship satisfaction, confidence, and self-esteem of men with SPS. The rate of psychosocial improvement does not correlate with penile size changes. It is a simple, safe, and effective technique that can be used in daily clinical practice.

Intercultural insights on the impact of different non-idealized models on men's body image and advertising perceptions

This experiment with 363 Irish and Flemish men aged 19 to 30 years (M = 23.56, SD = 2.36) investigated exposure to different male model ads (i.e. muscular, slim, plus-size, overall diversity, and no models) on well-being (i.e. body image, low body fat and muscularity attitudes, self-objectification, and self-esteem) and advertising outcomes (i.e. ad attitudes, brand attitudes, and purchase intent). Moderation effects of country and masculinity (i.e. dominance, winning) were investigated. The diversity condition generated more positive effects for low body fat attitudes than the muscular, slim, and no model conditions. Yet, no differences appeared for this outcome between the diversity and plus-size condition. No effects for the other well-being and advertising variables were found. Moderation analyses revealed higher purchase intent in the slim condition for men high in dominance. No effects were found for country and winning. Findings suggest that non-idealized models have protective effects for some men.

The effect of penis size on partner sexual satisfaction: a literature review

Larger penis size has been associated with a sign of strength, masculinity, and social standing. Little study has examined the relationship between men's penis size and their partners' sexual satisfaction. The purpose of the present study was to detail and evaluate the effect of penis size on partner sexual satisfaction with a design of narrative literature review. A systematic search of MEDLINE/PubMed was conducted to discover relevant studies on this issue. Currently, available studies show incomplete results between the penis size and partners' sexual satisfaction and are limited by methodological drawbacks, including small sample's size. The link between penis size and the sexual satisfaction of the partner need to be supported by more robust scientific evidence.

Social media and dating app use are differentially related to same- and next-day disordered eating pathology in young men with loss of control eating

OBJECTIVE

To evaluate whether social networking site (SNS) and dating app use is associated with disordered eating in young men.

METHODS

42 men (18-35y) who reported ≥4 loss of control (LOC) eating episodes in the prior month completed a 14-day ecological momentary assessment (EMA) protocol. Five times throughout the day, participants responded to prompts regarding their dietary restraint, body dissatisfaction, and LOC eating. Each night at ~10 pm, participants reported their total time spent on SNSs and dating apps/websites within the last day.

RESULTS

39 out of 42 cisgender men (M_age = 25.1 ± 5.3 years; 47 % non-Hispanic White, 29 % Black or African American; 63 % non-students; 87 % heterosexual) reported using SNSs and/or dating apps. Neither SNS nor dating app use was associated with body dissatisfaction. Dating app use with associated with higher same- (r² equivalent = 0.022, p = .003) and next-day dietary restraint (r² equivalent = 0.016, p = .02); SNS use was not. More SNS use was associated with lower odds of same- (OR [95 % CI] = 0.86 [0.75, 0.99], p = .044) and next-day LOC eating (OR [95 % CI] = 0.82 [0.71, 0.96], p = .011); links with dating app use were non-significant.

DISCUSSION

Non-significant links for SNS and dating app use with body dissatisfaction, and inverse associations with LOC eating, are contrary to research conducted with girls and women. Research is needed to evaluate whether the quality of SNS and dating app engagement (e.g., specific sites) are more closely related to men's disordered eating, and this work should consider muscularity concerns.

A theory based examination of factors associated with male body hair removal

Male body hair removal has implications for men's mental health such as anxiety about body image. Based on the Theory of Planned Behaviour and relevant additional constructs, this research examined factors associated with young men's upper body and pubic hair removal. Young men residing in Australia completed a pilot survey, online survey (N = 655) of predictors of intention (plans) to remove body hair and a 4-week follow up survey (n = 222) reporting body hair removal behaviour. Attitudes about body hair removal, pressure from others, perceptions of control and similarity to prototypical young men who removed body hair were associated with intention for upper body (60%) and pubic (48%) hair removal. Intention was significantly associated with body hair removal behaviours. These findings indicate social pressure was associated with young men's decisions to remove body hair, pointing to sources of potential intervention.

Spatial attentional biases toward height-related words in young males with physical stature dissatisfaction

By recording event-related potentials (ERPs) during a dot-probe task, the present study examined the neural dynamics of attentional bias toward height-related words among height dissatisfied males. Sixty male participants screened by Negative Physical Self Scale-Stature Concerns subscale (NPS-S) were assigned into a high height dissatisfaction (HHD) group and a low height dissatisfaction (LHD) group. The results showed that tall-related versus neutral words elicited larger N2pc for both HHD and LHD groups, whereas short-related versus neutral words elicited larger N2pc only for the HHD group. Additionally, an evident Pd was elicited by tall-related words for the HHD group, but not for the LHD group. Taken together, these findings revealed attentional biases toward height-related information for HHD individuals on a neural level. Specifically, HHD individuals showed an enhanced spatial attention oriented toward both tall-related and short-related words, and then, the allocated attention to the tall-related words was terminated by an active suppression mechanism.

Associations between negative gender attitudes and eating behaviors in Chinese children and adolescents

Background

Negative gender cognitive attitudes (disliking one's own gender or wanting to be the opposite gender) and unhealthy eating behaviors have become common in Chinese children and adolescents. The aim of this study was to analyze the associations between negative gender attitudes and eating behaviors among Chinese children and adolescents.

Methods

Primary and secondary school students aged 8-15 years were selected as participants using a stratified cluster random sampling method. The self-designed questionnaire was used to investigate the participants' negative gender cognitive attitudes. Eating frequency questionnaire was used to investigate participants' eating behaviors. Under the leading reading of standardized training investigators, the questionnaire for children aged 8-15 years was completed by themselves in the form of centralized filling.

Results

A total of 6.5% [43/657, boys: 6.1% (21/347), girls: 7.1% (22/310)] of children disliked their own gender, 8.8% [58/657, boys: 5.5% (19/347), girls: 12.6% (39/310)] of children wanted to be of the opposite gender, and the proportion of girls with negative gender attitudes was higher than that of boys (P < 0.05). Boys who disliked their own gender or wanted to be the opposite gender had higher frequencies of unhealthy eating behaviors and lower frequencies of healthy eating behaviors than boys who liked their own gender or did not want to be the opposite gender (P < 0.05). Girls who disliked their own gender or wanted to be the opposite gender had higher frequencies of protein eating behaviors than girls who liked their own gender or did not want to be the opposite gender (P < 0.05). There was a significant interaction between disliking one's own gender and wanting to be the opposite gender in midnight snack eating among boys (P < 0.05) and in carbonated drink and high protein eating behaviors among girls (P < 0.05).

Conclusion

Boys with negative gender cognitive attitudes express more unhealthy eating behaviors and fewer healthy eating behaviors; girls with negative gender cognitive attitudes exhibit more protein eating behaviors.

Small Intestinal Submucosa for corporeal body grafting in patients with proximal hypospadias and severe chordee: Long term follow-up assessing erectile function and genital self-perception

BACKGROUND

Proximal hypospadias and severe ventral chordee are often challenging to repair. To preserve penile length in chordee repair, Small Intestinal Submucosa (SIS) corporal grafting is often performed with potential long-term complications including recurrent curvature and erectile dysfunction (ED). There is a paucity of data evaluating sexual function in mid, late and post-pubertal patients.

OBJECTIVE

We aimed to assess long-term outcomes of genital self-perception and erectile function in mid, late and post-pubertal patients who underwent single-layer (1-ply) SIS corporal body grafting for correction of severe chordee.

STUDY DESIGN

Patients with proximal hypospadias who underwent correction of severe chordee using SIS grafting between 2001 and 2015 were retrospectively identified. Patients were evaluated for erectile and sexual function using the modified erection hardness score (mEHS) and the modified sexual health inventory for men (mSHIM). Perceived function and straightness were measured with Hypospadias Objective Scoring Evaluation (HOSE). Penile self-perception was assessed using the Pediatric Penile Perception Score (PPPS). Results were compared to an age-matched healthy control group. Categorical variables were analyzed using Fisher's exact test, and continuous variables using paired and unpaired t-test and ANOVA.

RESULTS

Nineteen patients with proximal hypospadias who underwent correction of severe chordee using SIS grafting and 18 controls participated in the study with a median age of 17 years for both groups. In the mEHS, 12 (63.2%) hypospadias-patients and 14 (87.5%) controls rated their erections as completely hard and very rigid. In the mSHIM, 1 (5.2%) hypospadias-patient was classified as having moderate ED. A total of 16 hypospadias-patients (84%) and 16 controls (88.9%) reported being very satisfied or satisfied with the straightness of their penis. No significant difference was observed in the mEHS, mSHIM and PPPS between groups (p < 0.05). The straightness of the erection was rated lower by participants, than by the pediatric urologist. In the HOSE, 12 (63.2%) hypospadias-patients and 16 (88.9%) controls obtained an acceptable score.

DISCUSSION

Our findings indicate favorable long-term outcomes in ED and genital self-perception; only 5% of our population reported having a mild-moderate to moderate presentation of ED, and there were no reports of severe ED. The overall PPPS satisfaction rates were statistically similar for the control and hypospadias groups. The small sample population limits the significance of our findings.

CONCLUSION

Corporal body grafting with 1-ply SIS suggests positive long-term outcomes in genital self-perception and erectile function, with mid, late and post-pubertal patients who underwent hypospadias repair having comparable results to age-matched healthy controls.

Sexual attraction to men as a risk factor for eating disorders: the role of mating expectancies and drive for thinness

BACKGROUND

Men tend to give more importance than women to physical aspects when selecting a partner; thus, the internalization of beauty standards and the ideal of thinness may be greater in populations attracted to men, placing them at a higher risk of eating disorders.

METHODS

In a sample (n = 398) of heterosexual and gay men and women, we evaluated the drive for thinness, body dissatisfaction, and bulimic symptomatology. Using ANCOVAs, we analyzed the differences in symptoms score according to sex, sexual orientation and relational status including body mass index (BMI) as covariate; we also evaluated the mediating role of drive for thinness in the relationship between sexual orientation and body dissatisfaction.

RESULTS

We found an increased drive for thinness and body dissatisfaction in men-attracted compared with women-attracted participants; also, body dissatisfaction was greater in women than in men. Heterosexual women presented higher bulimia scores than lesbian women. Gay men open to relationships presented higher drive for thinness and body dissatisfaction scores than those not-open to relationships. Finally, differences in body dissatisfaction between gay and heterosexual men were fully explained by drive for thinness, while, in the case of women, drive for thinness only partially explained these differences.

CONCLUSIONS

Attraction to men seems to be a risk factor for EDs in the case of gay men and heterosexual women. In addition, in the case of heterosexual women, other factors independent of the desire to attract men seem to be important.

"Guys with Big Muscles Have Misplaced Priorities": Masculinities and Muscularities in Young South Korean Men's Body Image

Men's body image is an issue of increasing importance as related illnesses continue to grow in prevalence around the world. However, cross-cultural attention to men's body image experiences has been relatively understudied. Based on data derived from cognitive anthropological methods of cultural domain analysis, I develop the concept of "muscularities" to more effectively examine the expectations inherent in multifarious models of body image men continuously navigate. Related to but distinct from "masculinities"-the recognition of culture-bound hierarchies of ways of doing-being a man-"muscularities" attends to the culturally particular ways in which muscles are conceived and evaluated as indices of socioeconomic status, intelligence, social skills, and professionalism, to name a few. Young South Korean men's experiences of chan'gŭnyuk ("small muscle") and manŭn kŭnyuk ("large muscle") challenge universalist assumptions about the kinds of muscles people value in global perspective, demonstrate the necessity of recognizing multiple muscularities in research, and encourage new directions of inquiry that attend to the consequences of variable embodiments of muscularities.

eLoriCorps Immersive Body Rating Scale and eLoriCorps Mobile Versions: Validation to Assess Body Image Disturbances from Allocentric and Egocentric Perspectives in a Nonclinical Sample of Adolescents

A growing number of studies have used virtual reality (VR) for the assessment and treatment of body image disturbances (BIDs). This study, conducted in a community sample of adolescents, documents the convergent and discriminant validity between (a) the traditional paper-based Figure Rating Scale (paper-based FRS), (b) the VR-based Body Rating Scale (eLoriCorps-IBRS 1.1), and (c) the mobile app-based Body Rating Scale (eLoriCorps-IBRS 1.1-Mobile). A total of 93 adolescents (14 to 18 years old) participated in the study. Body dissatisfaction and body distortion were assessed through the paper-based FRS, the eLoriCorps-IBRS 1.1 and the eLoriCorps-IBRS 1.1-Mobile. Eating disorder symptoms, body image avoidance, and social physique anxiety were also measured. Correlation analyses were performed. Overall, the results showed a good and statistically significant convergence between allocentric perspectives as measured by the paper-based FRS, the eLoriCorps-IBRS 1.1 and the eLoriCorps-IBRS 1.1-Mobile. As expected, the egocentric perspective measured in VR produced different results from the allocentric perspective, and from cognitive–attitudinal–affective dimensions of BIDs, with the exception of body distortion. These differences support the discriminant validity of the egocentric perspective of eLoriCorps-IBRS 1.1 and are consistent with emerging evidence, highlighting a difference between experiencing the body from an egocentric (i.e., the body as a subject) and allocentric (i.e., the body as an object) perspective. The egocentric perspective could reflect a perceptual–sensory–affective construction of BIDs, whereas allocentric measures seem to be more related to a cognitive–affective–attitudinal construction of BIDs. Moreover, the results support the validity of the eLoriCorps-IBRS 1.1-Mobile with promising perspectives of implementation among young populations.

An Evolutionary Perspective on Appearance Enhancement Behavior

Researchers have highlighted numerous sociocultural factors that have been shown to underpin human appearance enhancement practices, including the influence of peers, family, the media, and sexual objectification. Fewer scholars have approached appearance enhancement from an evolutionary perspective or considered how sociocultural factors interact with evolved psychology to produce appearance enhancement behavior. Following others, we argue that evidence from the field of evolutionary psychology can complement existing sociocultural models by yielding unique insight into the historical and cross-cultural ubiquity of competition over aspects of physical appearance to embody what is desired by potential mates. An evolutionary lens can help to make sense of reliable sex and individual differences that impact appearance enhancement, as well as the context-dependent nature of putative adaptations that function to increase physical attractiveness. In the current review, appearance enhancement is described as a self-promotion strategy used to enhance reproductive success by rendering oneself more attractive than rivals to mates, thereby increasing one's mate value. The varied ways in which humans enhance their appearance are described, as well as the divergent tactics used by women and men to augment their appearance, which correspond to the preferences of opposite-sex mates in a heterosexual context. Evolutionarily relevant individual differences and contextual factors that vary predictably with appearance enhancement behavior are also discussed. The complementarity of sociocultural and evolutionary perspectives is emphasized and recommended avenues for future interdisciplinary research are provided for scholars interested in studying appearance enhancement behavior.

Sexual Anxiety Mediates Dyadic Associations Between Body Satisfaction and Sexual Quality in Mixed-Sex Couples

Body satisfaction predicts sexual quality among women and men; however, mechanisms of the association are largely unknown. We hypothesized that sexual anxiety would mediate average associations over 1 year between individuals' body satisfaction and their own and their partner's sexual quality, which is comprised of their sexual satisfaction and dissatisfaction, in 123 mixed-sex cohabiting couples. Results of Actor-Partner Interdependence Models extended to Mediation (APIMeM) and tested via multilevel modelling partially supported the hypotheses. Specifically, individuals' body satisfaction indirectly predicted their own and their partner's sexual satisfaction through individuals' sexual anxiety, and indirectly predicted their own, but not their partner's sexual dissatisfaction through individuals' sexual anxiety. Thus, when individuals are relatively less satisfied with their bodies, they may experience anxiety during sexual encounters, which then interferes with their own and their partner's sexual quality.

High satisfaction on genital self-perception and sexual function in healthy Norwegian male adolescents

BACKGROUND

Genital self-perception and self-reported outcome on sexual function represent important information in studies focusing on male adolescents born with a genital malformation. Normal data from an age-matched control group are essential for comparison and more knowledge is needed concerning age after puberty and before entering adulthood.

OBJECTIVE

To investigate the self-reported outcome on genital perception and sexual outcome of healthy male adolescents aged 16 and 17 years.

STUDY DESIGN

Sixty-one individuals were included in this cross-sectional study. The assessment tools included the adolescents' self-report on genital perception and sexual function measured by the Pediatric Penile Perception Score (PPPS) and their responses to a semi-structured interview. In addition, we added information on mental health and psychosocial functioning measured by the Strengths and Difficulties Questionnaire, and health-related quality of life (HRQoL) measured by the Pediatric Quality of Life Inventory. Body satisfaction and self-esteem were also measured by the Global Self-Worth and Physical Appearance subscales of the revised version of the Self-Perception Profile for Adolescents (SPPA).

RESULTS

Of the 73 individuals invited, a total of 61 participated. The adolescents reported high satisfaction on genital self-perception and sexual function with a score close to 10 on the overall PPPS score (maximum overall score is 12). Participants who were dissatisfied with their genitals reported penile length, alongside foreskin, as their main concern. More than 90% reported satisfaction on sexual function, concerning erection, masturbation, ejaculation, and orgasm. Results showed a higher score on body satisfaction, self-esteem, mental health and psychosocial functioning and a lower score on HRQoL compared to the normative Norwegian data. The small numbers of individuals that scored more negatively on genital self-perception and sexual function also scored more negatively in all items studied.

DISCUSSION

A key finding in our study was their high satisfaction on the overall PPPS score and reported sexual function. The results are comparable to other studies related to healthy male adolescents and the sample studied deviate little from a representative Norwegian sample. A comparison group of age-matched adolescents from the normative population is important to determine long-term outcomes on genital appearance and sexual function of patients born with a genital malformation and operated on in early childhood. Limitations of this study are the small sample-size and the lack of information on non-participants.

CONCLUSIONS

Our results show generally positive genital self-perception and sexual function in a healthy group of Norwegian male adolescents, aged 16 and 17.

Does Size Matter? Perceptions of Indian Women About the Size of the Penis

Background:

Many men express concerns about their penile size, with respect to its role in sexual satisfaction of their female partners. The evidence to the contrary exists in the Western literature. However, similar evidence is lacking in a conservative society like India.

Aim:

This study aimed to evaluate the perception of Indian women about the size of the penis of their male partners with respect to sexual satisfaction.

Methodology:

A questionnaire-based study was carried out using a 20-item questionnaire in a sample of 230 sexually active Indian women, who answered the questionnaire either using pen and paper or using social media platform such as WhatsApp. Both the univariate and multivariate regression analysis was done using GraphPad software (©2020 GraphPad Software, Inc, California, USA). A P value less than .05 was considered statistically significant.

Results:

The study was conducted from January 2015 to December 2020. As per the accrued opinion of the women who participated in the study, there was no statistically significant correlation between the size of the penis and the sexual satisfaction.

Conclusion:

There is hardly any literature on the perception of women from a conservative society like India about the size of the penis of their partners in relation to the sexual satisfaction. Hence, the data from this study, which is the first of its kind form the Indian subcontinent, can be the basis to allay fears of men expressing their concerns about the size of their penis in this part of the world.

Anxiousness and Distractibility Strengthen Mediated Associations Between Men's Penis Appearance Concerns, Spectatoring, and Sexual Difficulties: A Preregistered Study

Men with penis appearance concerns are more likely to experience sexual difficulties because they engage in spectatoring (i.e., negative self-critical attentional focus during sex). This preregistered study investigated whether anxious and distractible personality traits make men with penis appearance concerns more likely to engage in spectatoring and, in turn, experience sexual difficulties. In a sample of 858 sexually active men in predominantly mixed-gender relationships, we replicated previous findings that penis appearance concerns were associated with greater spectatoring, and in turn greater problems with erection and orgasm. Additionally, our novel hypotheses that anxiousness and distractibility would strengthen these associations were partially supported. Anxiousness strengthened associations between penis appearance concerns and sexual embarrassment, and in turn was associated with greater reports of erectile and orgasmic difficulties. However, anxiousness did not strengthen the mediated associations between penis appearance concerns, self-focus, and erectile and orgasmic difficulties. Distractibility strengthened associations between sexual embarrassment and erectile difficulties, and in turn strengthened the mediated associations between penis appearance concerns, sexual embarrassment, and erectile difficulties. However, distractibility did not strengthen associations between sexual embarrassment and orgasmic difficulties, between sexual self-focus and erectile difficulties, nor between sexual self-focus and orgasmic difficulties. Implications for therapeutic treatments are discussed.

"eLoriCorps Immersive Body Rating Scale": Exploring the Assessment of Body Image Disturbances from Allocentric and Egocentric Perspectives

The first objective of this study was to test the convergent and discriminant validity between the “eLoriCorps Immersive Body Rating Scale” and the traditional paper-based figure rating scale (FRS). The second objective was to explore the contribution of the egocentric virtual reality (VR) perspective of eLoriCorps to understanding body image disturbances (BIDs). The sample consisted of 53 female and 13 male adults. Body size dissatisfaction, body size distortion, perceived body size, and ideal body size were assessed. Overall, outcomes showed good agreement between allocentric perspectives as measured via VR and the FRS. The egocentric VR perspective produced different results compared to both the allocentric VR perspective and the FRS. This difference revealed discriminant validity and suggested that eLoricorps’ egocentric VR perspective might assess something different from the traditional conception of body dissatisfaction, which an allocentric VR perspective generally assesses. Finally, the egocentric VR perspective in assessing BIDs deserves to be studied more extensively to explore the possibility of finding two types of body image distortion: (a) an egocentric perceptual body distortion, referring to internal body sensation affected by intra-individual changes, and (b) an allocentric perceptual body distortion, referring to external body benchmarks constructed by inter-individual comparison occurring in a given cultural context.

The Thin Man is His Clothing: Dressing Masculine to be Masculine

Body image research focuses almost exclusively on women or overweight and obesity or both. Yet, body image concerns among thin men are common and can result, at least in part, from mixed messages in society around how men qua men should dress and behave in order to look good and feel good. Stand-alone interventions to meet these different messages tend to provide men with little therapeutic relief. This conceptual paper draws on literature from the medical humanities; gender and body image studies; the social psychology of clothing; and the author's own lived experience to address this contemporary problem. The paper embraces visual culture as a resource that can frame discussion of how two sets of 'performativity' might reduce male anxiety about thinness. First, thin men could choose repeatedly to wear masculine-looking clothing, which could create their masculinity as a personal aesthetic that strengthens the confidence to harness masculine traits in healthy ways. Secondly, health and allied health service providers could promote and reinforce such dress behavior by offering advice that integrates aesthetic and functional aspects of clothing. Empirical studies are needed to test this dual model of performativity.

[Decision regret analysis among Chinese patients receiving penile girth enhancement with acellular dermal matrix]

OBJECTIVE

To evaluate decision regret among patients receiving penile girth enhancement with acellular dermal matrix (PGE with ADM) and to investigate the potential indicators for decisional regret so as to facilitate the decision-making process for this special group.

METHODS

In the study, 78 patients receiving PGE with ADM from Jun. 2016 to Jan. 2019 at Peking University People's Hospital and cooperative hospitals were eligible. Penile girth was taken by only one surgeon 1 week before surgery. Hospital anxiety and depression scale (HAD), international index of erectile function (IIEF) and a 10 cm long visual analogue scale named visualized penile image (VPI) were applied to measure psychological burden, erectile function and satisfaction with penile image respectively at the same time. All the patients were followed up for 3 months. Decision regret scale (DRS) was adopted for measuring decisional regret. Multivariate analysis of variance was applied to investigate the potential indicators for regret. Data analysis process was conducted with SPSS (version 24.0; SPSS, Chicago, IL, USA).

RESULTS

Mean penile girth recorded before intervention was (8.29±0.30) cm and increased to (9.46±0.29) cm post surgery (t=76.28, P < 0.01). As for both subscales of HAD measuring psychological burden, a signi-ficant reduction in the mean score was seen, that is, 2.8±1.3 (t=19.28, P < 0.05) for anxiety and 3.0±1.2 (t=20.67, P < 0.05) for depression, respectively. The average score of VPI increased by 3.7±1.1 (t=30.63, P < 0.05). There was no significant change in the average score of IIEF measuring erectile satisfaction (t=1.60, P=0.11). Twenty-nine (38.2%) patients expressed regret to some degree, and the mean DRS score was 23.4±14.8. The scores of DRS correlated negatively with scores of visualized penis image (r=-0.348, P < 0.01), and positively with scores of anxiety (r=0.760, P < 0.01) and depression subscale (r=0.471, P < 0.01). The scores of DRS was irrelevant to those of IIEF (r=0.02, P=0.867). The patients with high annual income (> 120 000 yuan) and education level above undergraduate were more prone to experience decision regret after intervention (P < 0.01).

CONCLUSION

PGE with ADM did augment penile girth and lower psychological burden, the regret rate of which was acceptably low among the patients. High income and good education might indicate more post-operative regret. Additional decision-making aids should be offered to patients with high income and education level above high school.

Average-Size Erect Penis: Fiction, Fact, and the Need for Counseling

Most men believe that the average length of an erect penis is greater than 6 inches (15.24 cm). This belief is due, in part, to several often-cited studies that relied on self-reported measurements, with means of about 6.2 inches (15.75 cm) for heterosexual men and even greater for gay men. These studies suffered from both volunteer bias and social desirability bias. In this review, the combined mean for 10 studies in which researchers took measurements of erect penises was 5.36 inches (13.61 cm; n = 1,629). For 21 studies in which researchers measured stretched penises, the mean was approximately 5.11 inches (12.98 cm; n = 13,719). Based on these studies, the average length of an erect penis is between 5.1 and 5.5 inches (12.95-13.97 cm), but after taking volunteer bias into account, it is probably toward the lower end of this range. Studies show that a majority of men wish they were larger, with some choosing penile lengthening surgery. These surgeries are considered by the American Urological Association to be risky. Most men seeking surgery have normal sized penises. Counseling with factual information about penis size might be effective in alleviating concerns for the majority of men who worry about having a small penis.

Auditory attentional biases in young males with physical stature dissatisfaction

The attentional biases toward body-related information for individuals with weight concerns and eating disorders have been well documented. However, our knowledge of the attentional biases toward body-related information for subjects with physical stature concerns is only at the beginning. And the research on the auditory attentional biases for individuals with physical stature concerns is rare. The identification of attentional biases may provide an impetus for interventions to reduce distress among height dissatisfied individuals. Therefore, the present study investigated the neural mechanisms of attentional bias toward auditory physical stature-related words among height dissatisfied young males by using event-related potential recordings. Forty-four young male participants screened by Negative Physical Self Scale-Stature Concerns subscale (NPS-S) were assigned into an experimental group with high levels of height dissatisfaction (HHD) and a control group with low levels of height dissatisfaction (LHD). Task irrelevant auditory tall-related words, short-related words and neutral words were presented unilaterally to the participants as the cue in a cue-target paradigm. Participants were required to respond to the visual target preceded by the task-irrelevant auditory cue. The results found that significantly larger N2ac was elicited by tall-related words than short-related words and neutral words only for the HHD group, but not for the LHD group. LPCpc amplitudes did not differ significantly by the functions of word types and experimental groups. These results suggest an attentional orienting bias toward auditory tall-related words for young males with high levels of height dissatisfaction.

Psychometric properties of the German version of the Self-Image Scale (SIS-D)

Background

The Self-Image Scale is a self-report measure originally developed for use in women with cancer. Two subscales assess appearance satisfaction (self-acceptance) and perceptions of partners’ acceptance of their appearance (partner-acceptance). This study aimed to increase the Self-Image Scale’s utility by 1) confirming the two-factor structure of the German version of the Self-Image Scale, 2) testing measurement invariance across sex and age groups and validity, and 3) gathering general population normative data.

Methods

Confirmatory factor analysis methods were used to examine the proposed two-factor model in a random sample of adults from the general German population (N = 1367). Measurement invariance, scale reliability, and validity were assessed.

Results

The original factor structure and measurement invariance across sexes and age groups were supported. Women showed significantly lower self-acceptance than men. Adolescent and young adult women showed higher self-acceptance than senior women. For both sexes, partner-acceptance lowered across successive age cohorts. Internal consistencies were good.

Conclusions

Results support the use of the German version of the Self-Image Scale in research and clinical practice. Research directions include validation in further diseases, collecting normative data across countries, and dyadic research, particularly exploring partner-acceptance across the life span.

Use of social networking sites and desire for slimness among 10-year-old girls and boys: A population-based birth cohort study

OBJECTIVE

Desire for slimness (DS) is a well-established risk factor for eating disorders among adolescents, particularly girls. It is known that exposure to traditional media such as television can increase DS. However, the association between DS and the use of new media, such as social networking sites (SNS), adjusting for relevant potential confounders, has not been examined to-date. In this study, we assessed the relationship between DS and SNS use among early adolescent girls and boys, adjusting for body mass index (BMI), time spent watching television, and Internet use.

METHOD

DS, SNS use, and confounding variables were assessed using self-report questionnaires and face-to-face interviews from a cross-sectional population-based survey of 4,478 10-year-old Japanese adolescents (2,100 girls and 2,378 boys).

RESULTS

After adjusting for confounding variables, SNS use was associated with increased risk of DS among girls (odds ratio [OR] = 1.93; 95% confidence interval [CI], 1.17-3.18, p = .010), but not among boys (OR = 1.07; 95% CI, 0.64-1.80, p = .786).

DISCUSSION

Exposure to SNS was associated with an increased risk of DS among early adolescents, especially girls. Targeting SNS use in early adolescence seems a promising approach to prevention of DS and subsequent eating problems, particularly among girls.

Stereotypes of physical attractiveness and social influences: The heritage and vision of Dr. Thomas Cash

Dr. Thomas Cash conducted seminal work on the beliefs and stereotypes related to attractiveness as well as their impact, and their transmission through cultural and interpersonal processes. This initial work has inspired and given rise to an important body of research significantly increasing our understanding of these processes. Here we review the initial contributions and research directions set up by Dr. Cash, as well as the main findings of the research that has built on his foundations. Specifically, we review findings related to the existence of attractiveness stereotypes and appearance ideals, research examining the social and interpersonal impacts of such stereotypes, and finally the sociocultural transmission of these beliefs. Future directions related to the extension of our understanding to appearance characteristics beyond shape and weight, as well as increased focus on minority identities and their intersection, are proposed.

Does masculinity moderate the relationship of height with height dissatisfaction? Findings from an Internet forum for short statured men

Research suggests that height is fundamental to Western conceptualisations of masculinity. However, researchers are yet to examine whether individual differences in conformity to Western masculine norms can help to explain why men experience height dissatisfaction. Thus, we investigated conformity to Western masculine norms as a moderator of the relationship between men's height and height dissatisfaction. Men experiencing height dissatisfaction (N = 249) were recruited from an Internet forum that functions as a discussion space for short-statured individuals. Results indicated that shorter men and more masculine men reported greater height dissatisfaction. As hypothesised, we observed a significant interaction between height and masculinity, such that the strength of the relationship of short stature with height dissatisfaction was stronger for more masculine men. Crucially, results from a Johnson-Neyman analysis indicated that it was only for men extremely low in their endorsement of masculine norms (i.e., the 2^nd percentile or lower) that the relationship of height with height dissatisfaction was nonsignificant, suggesting that, in the near-absence of masculine norm conformity, height no longer contributes to male body dissatisfaction. Whilst acknowledging that our findings require further exploration, we propose that conformity to masculine norms may be an influential factor in males' experience of height dissatisfaction.

Sociocultural Influences on Men's Penis Size Perceptions and Decisions to Undergo Penile Augmentation: A Qualitative Study

BACKGROUND

An increasing number of men, dissatisfied with their penises, are seeking cosmetic procedures to enhance their penis size. However, little is known about the social and cultural factors that influence men to consider these procedures.

OBJECTIVES

The aim of this study was to investigate the sociocultural factors affecting men's attitudes toward their penis size as well as their decisions to undergo penile augmentation.

METHODS

One-on-one semistructured interviews were conducted with 6 adult men who had previously undergone a penile augmentation. The men were asked about the sociocultural factors that they thought contributed to dissatisfaction with their penis size, and their motivations for having penile augmentation. All interviews were audio recorded and then transcribed verbatim. Interview transcripts were analyzed through the use of thematic analysis.

RESULTS

Three main themes emerged from the interviews, namely "influence of pornography," "comparison with peers," and "indirect appearance-related teasing." The men noted that the large penises of male actors in pornography had skewed their perception of normal penis size. All men had compared their penises with those of their peers, usually in the locker room, and often felt their own penis was smaller as a result. None of the participants had received direct negative comments about their penis size, but were aware that having a small penis was a source of mockery from exposure to jokes on mainstream media sources.

CONCLUSIONS

These new insights into the sociocultural factors, namely media and peers, that influence men's desire for penile augmentation may assist clinicians in enhancing their communication with prospective patients.

Body dissatisfaction in adolescent boys

Body dissatisfaction is a significant mental health symptom present in adolescent girls and boys. However, it is often either disregarded in adolescent boys or examined using assessments that may not resonate with males. The present study addresses these issues, examining the manifestation, etiology, and correlates of 3 facets of body dissatisfaction in adolescent boys. Adolescent male twins aged 16- to 17-years-old from the Swedish Twin Study of Child and Adolescent Development were included along with a female comparison group: 915 monozygotic and 671 dizygotic same-sex twins. Body dissatisfaction was defined using measures of height dissatisfaction, muscle dissatisfaction, and the body dissatisfaction subscale of the Eating Disorder Inventory (EDI-BD). We examined the prevalence of body dissatisfaction, whether the facets of body dissatisfaction were phenotypically and etiologically distinct, and associations with specific externalizing and internalizing symptoms. For boys, muscle dissatisfaction scores were greater than height dissatisfaction scores. Results also indicated that height and muscle dissatisfaction were phenotypically and etiologically distinct from the EDI-BD. Unique associations were observed with externalizing and internalizing symptoms: muscle dissatisfaction with symptoms of bulimia nervosa and the EDI-BD with internalizing symptoms, body mass index, and drive for thinness. The facets of body dissatisfaction were also largely distinct in girls and unique between-sex associations with externalizing and internalizing symptoms emerged. Overall, male-oriented aspects of body dissatisfaction are distinct from female-oriented aspects of body dissatisfaction. To capture the full picture of male body dissatisfaction, multiple facets must be addressed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Nonsurgical Medical Penile Girth Augmentation: A Retrospective Study of Psychological and Psychosexual Outcomes

BACKGROUND

Although interest in penile augmentation procedures is increasing, there is a significant lack of research into the psychological and psychosexual outcomes of these procedures.

OBJECTIVES

To investigate the psychological and psychosexual outcomes of nonsurgical medical penile girth augmentation.

METHODS

This retrospective study involved a mixed method approach. Twenty-five men who had undergone a nonsurgical medical penile girth augmentation between 1 and 12 months prior (mean, 6.6 months) completed an online questionnaire containing measures of procedure motivation, procedure satisfaction, genital self-image, penile-focused body dysmorphic disorder symptoms, self-esteem, and sexual relationship satisfaction. Six of these men elected to complete in-depth one-to-one semi-structured phone interviews to further explore the psychological impacts of the procedure.

RESULTS

In the online questionnaire, most men were satisfied with their penile size, appearance, and function after penile girth augmentation. The men also reported statistically significant improvements in their genital self-image (P < 0.001) and self-esteem (P = 0.008), and a reduction in penile-focused body dysmorphic disorder symptoms (P = 0.002) at the time of completing the questionnaire compared to recalled pre-procedural levels. The in-depth interviews yielded 3 themes surrounding penile augmentation outcomes: (1) high satisfaction with increased penis girth; (2) increased self-confidence, particularly in situations in which the penis would be seen, such as a locker room; and (3) increased sexual confidence, but some mixed impacts on sexual relationships.

CONCLUSIONS

Most men appear to be satisfied with their nonsurgical medical penile girth augmentation results, and they also seem to experience improvements in their overall self-esteem.

Social Desirability and Young Men's Self-Reports of Penis Size

Previous studies demonstrate that many men have insecurities about the size of their penises, often resulting in low sexual self-esteem and sexual problems. In the present study, mean self-reported erect penis length by 130 sexually experienced college men (6.62 inches) was greater than found in previous studies in which researchers took measurements. This suggests that many of the men embellished their responses. Only 26.9% of the sexually experienced men self-reported penis lengths of less than 6 inches, while 30.8% self-reported lengths of 7 inches or more (with 10% self-reporting 8 inches or more). The correlation with Marlowe-Crowne social desirability scores was +.257 (p < .01), indicating that men with a high level of social desirability were more likely than others to self-report having a large penis.

Spectatoring Mediates the Association Between Penis Appearance Concerns and Sexual Dysfunction

Men with penis appearance concerns are more likely to experience sexual dysfunction, but the processes underlying this association are unknown. This study investigated whether spectatoring (i.e., negative self-directed attentional focus during sex) mediates the association between penis appearance concerns and sexual dysfunction. Men in romantic relationships (N = 512, in predominantly mixed-gender relationships) reported on sex they had with their partner in the previous month. Indirect effects indicated that penis appearance concerns predicted greater spectatoring, and in turn predicted greater erectile and orgasmic dysfunction. Results suggest that spectatoring is a conduit through which penis appearance concerns impede sexual function.

Negative Body Attitudes and Sexual Dissatisfaction in Men: The Mediating Role of Body Self-Consciousness During Physical Intimacy

Previous research indicated that negative attitudes about the body and appearance are common among men and demonstrated that negative body attitudes are associated with negative sexual experiences. The present study investigated the association between body attitudes and sexual dissatisfaction and the mediating role of body self-consciousness during physical intimacy. In a cross-sectional design, 201 Dutch men completed an online survey regarding body attitudes toward muscularity, body fat, height, and genitals, body self-consciousness during physical intimacy, and sexual dissatisfaction. Hypotheses were tested using correlation analyses and a mediation analysis with body attitudes as predictors, body self-consciousness as mediator, and sexual dissatisfaction as outcome. Correlation analyses showed that negative body attitudes and body self-consciousness during physical intimacy were significantly related to sexual dissatisfaction. The mediation analysis revealed that negative attitudes toward muscularity, body fat, and genitals had indirect effects on sexual dissatisfaction through body self-consciousness during physical intimacy. Negative attitudes toward genitals additionally had a direct effect on sexual dissatisfaction. These findings indicate that body image interventions focused on male body attitudes may be beneficial in improving men's body image, which may ultimately increase sexual satisfaction.

The Contribution of Social Media to Body Dissatisfaction, Eating Disorder Symptoms, and Anabolic Steroid Use Among Sexual Minority Men

Social media has been associated with body dissatisfaction and eating disorder symptoms among young women and adolescent girls. However, despite notable evidence of susceptibility to body image pressures, it remains unknown whether these associations generalize to sexual minority men. A nationwide sample of 2,733 sexual minority men completed an online survey advertised to Australian and New Zealand users of a popular dating app. Participants answered questions about how frequently they used 11 different social media platforms in addition to questions about their dating app use, body image, eating disorder symptoms, and anabolic steroids. Facebook, Youtube, Instagram, and Snapchat were the most frequently used social media platforms. A pattern of small-sized and positive associations emerged between social media use and body dissatisfaction, eating disorder symptoms, and thoughts about using anabolic steroids. Facebook, Instagram, and Snapchat evidenced the strongest associations. The associations of social media use with both muscularity dissatisfaction and eating disorder symptoms were stronger for image-centric social media platforms (e.g., Instagram) than nonimage-centric platforms (e.g., Wordpress); no differences were observed for body fat dissatisfaction, height dissatisfaction, or thoughts about using anabolic steroids. Previously documented associations of social media use with body dissatisfaction and related variables among women and girls appear to generalize to sexual minority men. Social media platforms that more centrally involve imagery may be of greater concern than nonimage-centric platforms. Additional research with sexual minority men is needed to elucidate the distinctions between adaptive and maladaptive social media use in the context of body dissatisfaction, eating disorders, and anabolic steroid use.

Eye Movement Study on Attention Bias to Body Height Stimuli in Height Dissatisfied Males

The present study investigated attention bias in response to height-related words among young men in China. 47 [26 high height dissatisfied (HHD) and 21 low height dissatisfied (LHD)] men performed a dot-probe task. Eye movement (EM) recordings showed that compared to LHD men, HHD men had an avoidance bias in response to height-related words, which was revealed by less frequent first fixations on both tall-related and short-related words, and showed significantly shorter first fixations on short-related words. There was no other significant difference in EM indices (i.e., first fixation latency and gaze duration) between two groups. In addition, HHD participants were significantly slower than LHD participants when responding to probes preceded by short-related words, while there was no difference when probes were preceded by tall-related or neutral words. In sum, the present results indicate that HHD men selectively avoid cues related to short height.

Adults’ Narratives of Growing up with a Cleft Lip and/or Palate: Factors Associated with Psychological Adjustment

Background

Growing up with a cleft lip and/or palate presents a number of challenges for those affected and their families. Understanding why some individuals cope well while others struggle is key to psychological research in this field. A better appreciation of the factors and processes that contribute to psychological adjustment to cleft lip and/or palate (CL/P) from the patient perspective would be of value to both researchers and clinicians.

Design

Qualitative data elicited from individual interviews with 52 adults born with CL/P.

Result

Inductive thematic analysis identified three main themes: “background” factors (age, gender, sexual orientation, culture, additional conditions, socioeconomic status, and adoption), “external” factors (treatment autonomy, familial coping and support, salience, public understanding, psychological input, and peer support), and “internal” psychological factors (perceptions of difference, noticeability and teasing, social confidence, internalization of beauty ideals, valence, expectations of treatment, responding to challenges, social comparisons, acceptance, faith, dispositional style, and recognition of strengths and positive growth).

Conclusions

The number and breadth of factors identified in this study are testament to the importance of psychology in the field of CL/P and may offer guidance in relation to developing and assessing the value of psychological interventions. There is a clear role for psychologists in tackling appearance-related concerns, designing materials, supporting patient decision making, and improving social interaction, as well as providing specialist psychological support. The findings illustrate the potential degree of individual variation in perspectives and offer insight into the conflicting results found within current literature.

The tall and the short of it: An investigation of height ideals, height preferences, height dissatisfaction, heightism, and height-related quality of life impairment among sexual minority men

Human height has attracted empirical interest from a variety of psychological perspectives. However, little research has explored height from the perspective of sexual minority men, inclusive of their height beliefs, height preferences, height dissatisfaction, experiences of heightism, and height-related quality of life impairment. We explored these height variables in 2733 sexual minority men who completed a survey distributed nationwide to Australian and New Zealander users of geosocial-networking smartphone applications. Results showed that men's ideal height (M=182.26cm, SD=5.93cm) was taller than their actual height (M=178.96cm, SD=7.52cm). Shorter and taller men reported negative and positive treatment from others due to their height, respectively, with the cross-over (i.e., neutral) point at approximately 175-176cm. Heightism was reported by 11.0% of men. Height dissatisfaction and heightism were uniquely associated with quality of life impairment; the size of these associations was small.

Fat or fiction? Effects of body size, eating pathology, and sex upon the body schema of an undergraduate population

Although there is a growing consensus that women with anorexia nervosa have a distorted body schema, the origins of this disturbance remain uncertain. The present investigation examined the effects of body size, eating pathology, and sex upon the body schema of an at-risk, undergraduate population. In Study 1, 98 participants mentally simulated their passage through apertures. When aperture width was manipulated, narrow and broad women over- and under-estimated their spatial requirements for passage, respectively. This relationship was exacerbated by dietary restraint. When aperture height was manipulated, short and tall men over- and under-estimated their spatial requirements for passage, respectively. Study 2 (N=32) replicated the association between women's veridical and internally-represented widths, although no significant effects of eating pathology were observed. Our findings suggest that body schema enlargement is not necessarily pathological, and may be driven by normal perceptual biases and internalised sociocultural body ideals.

Anabolic steroid use among gay and bisexual men living in Australia and New Zealand: Associations with demographics, body dissatisfaction, eating disorder psychopathology, and quality of life

BACKGROUND AND AIMS

Gay and bisexual men may be at heightened risk for using anabolic androgenic steroids (AAS). Few studies, however, have examined AAS use among gay and bisexual men living in countries outside the United States. In addition, few studies have explored the potential associations of AAS use with body image concerns beyond muscularity, including height and genitals, or with eating disorder symptoms and quality of life. Thus, we examined the associations of AAS use, and of thoughts about using AAS, with body image, eating disorder symptoms, and quality of life among gay and bisexual men living in Australia and New Zealand.

METHODS

A sample of 2733 gay and bisexual men completed an online survey promoted by paid nationwide advertisements to users of geosocial-networking smartphone applications.

RESULTS

The prevalence of AAS use, and of thoughts about using AAS, were 5.2% (95% confidence interval [CI]: 4.4%, 6.1%) and 25.4% (95% CI: 23.8%, 27.1%), respectively. Multivariate analyses revealed that more frequent thoughts about using AAS were associated with being older, taller, and experiencing greater dissatisfaction with muscularity and height, less dissatisfaction with body fat, greater eating disorder symptoms, and lower subjective quality of life. Actual AAS users were more likely to be older, from a non-Australian/New Zealander cultural background, experiencing less dissatisfaction with body fat, and experiencing greater eating disorder symptoms.

CONCLUSIONS

Psychopathology related to body image and eating disorders are associated with AAS use among gay and bisexual men living in Australia and New Zealand.

A pilot controlled trial of a cognitive dissonance-based body dissatisfaction intervention with young British men

This pilot study evaluated a body image intervention for men, Body Project M. Seventy-four British undergraduate men took part in two 90-min intervention sessions, and completed standardised assessments of body image, bulimic pathology, and related outcomes at baseline, post-intervention, and 3-month follow-up. Fifty-three other men completed the questionnaires as an assessment-only control group. Per-protocol analysis showed that Body Project M improved men's dissatisfaction with body fat and muscularity, body appreciation, muscularity enhancing behaviours, appearance comparisons, and internalization (ds=0.46-0.80) at post-intervention. All except dissatisfaction with muscularity and internalization were sustained at 3-month follow-up. No effects were found for bulimic pathology. Post-intervention effects for dissatisfaction with muscularity and internalization only were retained under intention-to-treat analysis. Participants were favourable towards the intervention. This study provides preliminary evidence for the acceptability and post-intervention efficacy of Body Project M. Further development of the intervention is required to improve and sustain effects.

[Inaccurate information about the size of the penis in the Democratic Republic of the Congo: about 21 information sources]

Introduction

La taille du pénis constitue une préoccupation de beaucoup des gens actuellement et certains ne sont pas satisfaits de la dimension de leur pénis comme le montre l’étude de Tiggemann en 2008. Il existe relativement peu d'études sur le pénis en érection. Cela peut refléter les tabous culturels des chercheurs ou des médecins en interaction avec les hommes qui sont dans un état d’excitation sexuelle. Toutes fois, il est important pour les personnes qui annoncent des détails sur la taille du pénis d’annoncer d’abord les repères de la mesure du pénis puis ensuite donner les chiffres que proposent les chercheurs.

Méthodes

Notre enquête de type descriptif transversale s’est effectuée dans les deux grandes villes de la République Démocratique du Congo à savoir la ville de Kinshasa et la ville de Lubumbashi, pendant une période de deux ans soit de Mai 2014 à Mai 2016. Au total, 21 sources d’information ont constitué notre échantillon dont 8 à Kinshasa et 13 à Lubumbashi et nous avons trouvé cela suffisant car les sujets à caractère sexuel sont souvent rares chez nous. Les paramètres étudiés étaient: la nature de la source, la précision de la technique de la mesure, la présence de référence bibliographique, la longueur annoncée du pénis.

Résultats

La majorité des sources d’information sont faites des émissions de radio et de télévision (23,8%), ceci pourra s’expliquer par le fait que dans notre milieu il y a de plus en plus des chaines de radio et télévision et surtout dans les grandes villes. Concernant la précision de la technique de la mesure du pénis lors du partage du message sur la taille du pénis, l’étude nous montre que la majorité des sources d’information ne signale pas cela lorsqu’elles annoncent la taille du pénis au public soit 85,7%. Plusieurs sources ne déclarent pas les références bibliographiques (57,1%). Lorsqu’on regarde même les chiffres de la taille du pénis annoncée, l’on voit les proportions majoritaires suivantes: 14 cm comme taille normale soit 28,6%, suivi de ceux là qui disent 15 cm soit 23,8% et de 15 à 20 cm soit 19%.

Conclusion

Ces résultats sont une interpellation des tous les acteurs responsables de la diffusion de l’information sur la santé sexuelle (taille du pénis): la rigueur scientifique consiste à chercher l’information dans des sources fiables.

Internalization of appearance ideals mediates the relationship between appearance-related pressures from peers and emotional eating among adolescent boys and girls

Appearance-related pressures have been associated with binge eating in previous studies. Yet, it is unclear if these pressures are associated with emotional eating or if specific sources of pressure are differentially associated with emotional eating. We studied the associations between multiple sources of appearance-related pressures, including pressure to be thin and pressure to increase muscularity, and emotional eating in 300 adolescents (M_age=15.3, SD=1.4, 60% female). Controlling for age, race, puberty, body mass index (BMI) z-score, and sex, both pressure to be thin and pressure to be more muscular from same-sex peers were positively associated with emotional eating in response to feeling angry/frustrated and unsettled (ps<0.05). Pressure from same-sex peers to be more muscular also was associated with eating when depressed (p<0.05), and muscularity pressure from opposite-sex peers related to eating in response to anger/frustration (p<0.05). All associations were fully mediated by internalization of appearance ideals according to Western cultural standards (ps<0.001). Associations of pressures from mothers and fathers with emotional eating were non-significant. Results considering sex as a moderator of the associations between appearance-related pressures and emotional eating were non-significant. Findings illustrate that both pressure to be thin and muscular from peers are related to more frequent emotional eating among both boys and girls, and these associations are explained through internalization of appearance-related ideals.

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

INTRODUCTION

We prospectively investigated the relationship between newborn male circumcision (NMC) and second to fourth digit ratio with penile length.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Prevalence and Motivation: Pubic Hair Grooming Among Men in the United States

Pubic hair grooming is a growing phenomenon and is associated with body image and sexual activity. A nationally representative survey of noninstitutionalized adults aged 18 to 65 years residing in the United States was conducted. Differences in demographic and sexual characteristics between groomers and nongroomers were explored. Four thousand one hundred and ninety-eight men completed the survey. Of these men, 2,120 (50.5%) reported regular pubic hair grooming. The prevalence of grooming decreases with age, odds ratio = 0.95 (95% confidence interval [0.94, 0.96]), p < .001. Adjusting for sexual frequency and sexual orientation, grooming is associated with performing and receiving oral sex. The majority of men report grooming in preparation for sexual activity with a peak prevalence of 73% among men aged 25 to 34 years, followed by hygiene (61%) and routine care (44%). The majority of men who remove their pubic hair groom the hair above the penis (87%), followed by the scrotum (66%) and the penile shaft (57%). Overall, pubic hair grooming is common among men aged 18 to 65 years in the United States. Younger ages are associated with greater rates of pubic hair grooming. Many men groom for sex, in particular oral sex, as well as for routine care and hygiene.
