RESUMEN

AIM: This study aims to examine the relationship between male genital self-perception and sexual functioning and depression anxieties. METHOD: The study included male patients who were referred to the andrology outpatient clinic between March 2022 and June 2022. Demographic data of the patients were recorded. Cigarette and alcohol consumption was also noted. The Male Genital Self Image Scale (MGSIS) questionnaire was used for the Genital Self Image(GSI) assessment, which consists of 7 questions. The International Index of Erectile Function (IIEF), composed of 15 questions, was used to evaluate sexual function. STAI-I, STAI-II, and BECK scales were used for depression and anxiety. The penis size of the patients was measured in a flask and stretched condition, and the midpenile circumference was recorded. Patients were compared with respect to GSI, depression, anxiety, and sexual functioning. RESULTS: A total of 75 patients were included in the study. The mean age of the patients was 46.69 ± 11.32 (26-72), and the mean BMI was 27.82 ± 3.79 (22.46-40.40) kg/m2. A slightly positive correlation was found between the patients' flask penis size and MGSIS-total scores (r = 0.260, p = .024) and IIEF-SF scores (r = 0.240, p = .038). There was a moderately positive correlation between the stretched penis size and IIEF-OS (r = 0.403, p < .001) and IIEF-SF (r = 0.354, p = .002). While the MGSIS-total score and the STAI-I and STAI-II scores had a moderate negative correlation, there was an advanced negative correlation between the MGSIS-total score and the BECK score. CONCLUSION: Disruption of men's genital self-perception is moderately related to their susceptibility to depression and anxiety. This situation affects the person's sexual performance and causes orgasm problems to increase.

RESUMEN

In this study, we formally examine the association between penis size dissatisfaction and gun ownership in America. The primary hypothesis, derived from the psychosexual theory of gun ownership, asserts that men who are more dissatisfied with the size of their penises will be more likely to personally own guns. To test this hypothesis, we used data collected from the 2023 Masculinity, Sexual Health, and Politics (MSHAP) survey, a national probability sample of 1,840 men, and regression analyses to model personal gun ownership as a function of penis size dissatisfaction, experiences with penis enlargement, social desirability, masculinity, body mass, mental health, and a range of sociodemographic characteristics. We find that men who are more dissatisfied with the size of their penises are less likely to personally own guns across outcomes, including any gun ownership, military-style rifle ownership, and total number of guns owned. The inverse association between penis size dissatisfaction and gun ownership is linear; however, the association is weakest among men ages 60 and older. With these findings in mind, we failed to observe any differences in personal gun ownership between men who have and have not attempted penis enlargement. To our knowledge, this is the first study to formally examine the association between penis size and personal gun ownership in America. Our findings fail to support the psychosexual theory of gun ownership. Alternative theories are posited for the apparent inverse association between penis size dissatisfaction and personal gun ownership, including higher levels of testosterone and constructionist explanations.

RESUMEN

Bodily markers, often self-reported, are frequently used in research to predict a variety of outcomes. The present study examined whether men, at the aggregate level, would overestimate certain bodily markers linked to masculinity, and if so, to what extent. Furthermore, the study explored whether the amount of monetary rewards distributed to male participants would influence the obtained data quality. Men from two participant pools were asked to self-report a series of bodily measures. All self-report measures except weight were consistently found to be above the population mean (height and penis size) or the scale midpoint (athleticism). Additionally, the participant pool that received the lower (vs. higher) monetary reward showed a particularly powerful deviation from the population mean in penis size and were significantly more likely to report their erect and flaccid penis size to be larger than the claimed but not verified world record of 34 cm. These findings indicate that studies relying on men's self-reported measures of certain body parts should be interpreted with great caution, but that higher monetary rewards seem to improve data quality slightly for such measures.

RESUMEN

OBJECTIVES: To investigate alterations in depicted penis size by evaluating nude male paintings from the 15th to 21st centuries. MATERIALS AND METHODS: Nude-male paintings were identified from various art history websites and analysed to determine changes in penis size over time. Two observers organised the paintings according to the century in which they were created and made the calculations. Penile length to ear length (PtEL) or penile length to nose length (PtNL) were calculated to standardise the measurements using professional image analysis software. PtEL was first attempted for all paintings; if PtEL could not be ascertained, then nose length was used instead of the ear, as the nose length is defined as equal to ear length according to the golden ratio. Thus, PtNL was ensured and both ratios were then referred to using a common term: penis depiction ratio (PDR). Further analysis was performed by dividing the paintings into three groups according to the historical development of art: Renaissance Period (1400-1599; 15th-16th centuries), Baroque-Rococo and Impressionism Period (1600-1899; 17th-19th centuries) and Contemporary Art Period (1900-2020; 20th and 21st centuries). RESULTS: Of 232 identified paintings, 72 (31.1%) were excluded because they depicted images of adolescents or an erect penis. The PDR was found to differ significantly between paintings created in different centuries (P < 0.001). Subgroup analysis revealed that paintings from the 21st century demonstrated significantly higher PDRs than paintings from previous centuries (P = 0.001). CONCLUSIONS: In paintings depicting nude males, the size of the penis has gradually increased throughout the past seven centuries, and especially after the 20th century. This observation illustrates the changing sociocultural inputs into male body image and emphasises the need for improved understanding of the sociocultural factors associated with the perception of penis size in men.

RESUMEN

INTRODUCTION: The "lost penis syndrome" (LPS) is a term often used in non-clinical settings to describe the subjective perception of the loss of cutaneous and proprioceptive feelings of the male organ during vaginal penetration. Although deserving clinical attention, this syndrome did not receive any consideration in the medical literature. Notwithstanding, it represents a relatively unexceptional condition among patients in sexual medicine clinics, and it is often reported together with other sexual dysfunctions, especially delayed ejaculation, anejaculation, male anorgasmia and inability to maintain a full erection. OBJECTIVES: To draft a new conceptual characterization of the LPS, defined as a lack of penile somesthetic sensations during sexual penetration due to various causes and leading to several sexual consequences in both partners. METHODS: Based on an extensive literature review and physiological assumptions, the mechanisms contributing to friction during penovaginal intercourse, and their correlation to LPS, have been explored, as well as other nonanatomical factors possibly contributing to the loss of penile sensations. RESULTS: Efficient penile erection and sensitivity, optimal vaginal lubrication and trophism contribute to penovaginal friction. Whenever one of these processes does not occur, loss of penile sensation defined as LPS can occur. Sociocultural, psychopathological and age-related (ie, couplepause) factors are also implicated in the etiology. Four types of LPS emerged from the literature review: anatomical and/or functional, behavioral, psychopathological and iatrogenic. According to the subtype, a wide variety of treatments can be employed, including PDE5i, testosterone replacement therapy and vaginal cosmetic surgery, as well as targeted therapy for concomitant sexual comorbidity. CONCLUSION: We held up the mirror on LPS as a clinically existing multifactorial entity and provided medical features and hypotheses contributing to or causing the occurrence of LPS. In the light of a sociocultural and scientific perspective, we proposed a description and categorization of this syndrome hypothesizing its usefulness in daily clinical practice.

RESUMEN

BACKGROUND: Penis size is a highly sensitive topic, which has often raised concerns associated with human masculinity and male sexual health. Although data regarding penile dimensions have been published worldwide, little is known about these measurements in South-East Asian countries. OBJECTIVE: This study aimed to provide the reference range in penile length, circumference, and diameter of Vietnamese men and their variations among men with erectile dysfunction and other diseases. MATERIALS AND METHODS: Information about flaccid length, stretched length, mid-shaft circumference, and glans diameter from the health records of 14,597 men attending the Andrology Consultation was collected. These men were classified into three groups being regular reproductive health screening group, sexual dysfunction group, and other disease groups. RESULTS: We found that penile dimensions follow a non-parametric distribution, as tested by Kolmogorov-Smirnov test. The median values are 9.03 cm for flaccid length, 14.67 cm for stretched length, 8.39 cm for mid-shaft circumference, and 2.86 cm for unaroused glans diameter. Length and girth of the penis also changed among the different groups, especially in flaccid state; specifically, men with erectile dysfunction had a greater value in all penile dimensions except for change ratio compared with other groups. Circumcision, which rarely occurs in Vietnam, was associated with a 2 mm reduced penis length. DISCUSSION: Findings on correlations between penile dimensions and somatometric parameters from previous studies are questionable and some measurements, such as glans dimension, have not been thoroughly investigated so far. Nevertheless, penile dimensions provide useful insight concerning conditions affecting sexual development and might be a valuable parameter in the assessment of erectile dysfunction. CONCLUSION: Results of this study provide informative materials for the assessment of penile size, including reference values drawn from a large sample of Vietnamese men that can be useful in clinical practice and sexual health education.

RESUMEN

Three experiments investigated the influence of penile erection on ascriptions of mental capabilities to men. Drawing on sexual objectification literature and the distinction between agency and experience in mind perception, three competing predictions were formulated. The mind redistribution hypothesis assumed that penile erection would lower agency and heighten experience attributions, the animalistic dehumanization hypothesis predicted the decrease in agency, but not experience, and the literal objectification hypothesis implied the simultaneous decrease in both agency and experience. In Experiment 1 (N = 219; 128 females), erection salience lowered agency, but not experience capabilities ascribed to male targets. Experiment 2 (N = 201, 113 females) replicated the negative effect of erection salience on perceived agency (but not experience) and revealed that erection salience lowered intentions to hire a male target. This effect was explained with the loss of perceived agency. Experiment 3 (N = 203, 98 females) verified the causal relationship between penile erection, agency and hiring intentions. Taken together, these results supported the animalistic dehumanization hypothesis.

RESUMEN

Evolution has generated enormous diversity in animal genitalia. However, the importance of private property in driving penis size evolution has rarely been explored. Here, I introduce a novel hypothesis, the 'private parts for private property' hypothesis, which posits that enlarged penises evolved to prevent the theft of property during sex. I tested this hypothesis in hermit crabs, which carry valuable portable property (a shell) and which must emerge from this shell during sex, risking social theft of their property by eavesdroppers. I measured relative penis size (penis-to-body ratio) for N = 328 specimens spanning nine closely related species. Species carrying more valuable, more easily stolen property had significantly larger penis size than species carrying less valuable, less easily stolen property, which, in turn, had larger penis size than species carrying no property at all. These patterns in penis size remained even when phylogeny was controlled for, and the patterns were not explained by alternative hypotheses. Instead, the results suggest larger penises evolved as morphological adaptations to facilitate safe sex, in which individuals retain their valuable property by extending a long penis outside the shell to copulate. This hypothesis may likewise apply to other taxa, including those with valuable but non-portable property.

RESUMEN

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. In 2002, lagoon samples exhibited Relative Penis Size Index (RPSI) higher than marine samples, whereas no differences were detected in the recent survey, when all RPSI values were below 0.6%. Vas Deference Sequence Index (VDSI) mean values were over 4 before the ban introduction and below this value after that, indicating more critical conditions for gastropod population in 2002 rather than in 2013-15. Percentage of sterile females was up to 69% in 2002, whilst in the more recent survey no sterile female was found. Range of BT concentrations in gastropods decreased from 252 to 579 to 16-31ng∑BT/g d.w. BT body burdens varied according to a gender dependant pattern, with higher concentrations observed in females than in males. A first attempt to propose a classification based on BT impact on H. trunculus, according to the Water Framework Directive, revealed that most sites were in Bad ecological status before the ban and attained a Poor/Moderate status after that.

RESUMEN

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 (5-6.5 inches) and receptive sexual acts (bottoming), and larger (8.5-13 inches) with penetrative acts (topping). These observations are supported through the qualitative textual readings of how the performers are described on these popular sites, revealing the narratives and marketing strategies that shape the construction of popular porn brands, performers, and profitable fantasies.

RESUMEN

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 %). No demographic characteristics (age, race, sexual orientation, education, location, and income) were significantly associated with genital dissatisfaction. Men who were dissatisfied with their genitals were less likely to report being sexually active (73.5 %) than those who were satisfied (86.3 %). Penetrative vaginal sex (85.2 vs. 89.5 %) and receptive oral intercourse (61.0 vs. 66.2 %) were reported less by dissatisfied men. Overall, most U.S. men were satisfied with their genitals; however, a subset (14 %) report low genital satisfaction, which included men of all ages, races, and socioeconomic groups. Low genital satisfaction is associated with a decrease in sexual activity. These results provide clinicians and health educators a baseline of genital satisfaction to provide education and reassurance.

RESUMEN

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.g., pleasure, control, anxieties, and gender typicality). Results suggested that men's sexual position self-label was learned over a 15-year timespan. Ages of first same-sex genital manipulation and first anal sex experiences were related to age at first self-labeling. With respect to predictors of labels, a multivariate path model was created. The model did not support the direct importance of penis size, but identified indirect paths that linked penis size to top/bottom identification (e.g., smaller penis sizes leading to topping-anxieties and thus, a bottom label). Finding bottoming to be pleasurable and the importance of sexual control dynamics were the only two direct predictors. The path model substantiated the reliance both bottoms and tops show towards seeking (or not seeking among tops) gender typical, sexually dominant partners. It also supported previous evidence regarding race; specifically, while race may activate differences in sexual behavioral dynamics, it is not a great predictor of the sexual position self-label. This study shows that sexual position self-labeling has enormous complexity and cannot be reduced down to penis size.

RESUMEN

INTRODUCTION: Research on long-term results of hypospadias has focused on surgical techniques and functional outcomes, and it is only recently that patient satisfaction with appearance and psychosocial outcomes have been considered. The aim of this study was to provide an evidence-based systematic review of adolescent and adult patient perceptions of cosmetic outcomes following childhood surgery for hypospadias. METHODS: A systematic review was performed in accordance with the PRISMA and PICO guidelines, and studies assessed using the Oxford Centre for Evidence-Based Medicine system. MEDLINE, PsycInfo, EMBASE, and CINAHL databases were searched from 1974 to 2014 for clinical studies containing patient perceptions of appearance, deformity, and social embarrassment following hypospadias surgery. RESULTS: A total of 495 publications were retrieved, of which 28 met the inclusion criteria. Due to study design/outcome measure, heterogeneity data were synthesized narratively. Results indicate (i) patient perceptions of penile size do not differ greatly from the norm; (ii) perceptions of appearance findings are inconsistent, partially due to improving surgical techniques; (iii) patients who are approaching, or have reached, sexual maturity hold more negative perceptions and are more critical about the cosmetic outcomes of surgery than their prepubertal counterparts; (iv) patients report high levels of perceptions of deformity and social embarrassment; and (v) there is a lack of data using validated measurement tools assessing long-term patient perceptions of cosmetic outcomes, particularly with patients who have reached genital maturity. CONCLUSIONS: Protocols for clinical postpuberty follow-up and methodologically sound studies, using validated assessment tools, are required for the accurate assessment of cosmetic and psychological outcomes of hypospadias surgery.

RESUMEN

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 SPA group showed a larger discrepancy than controls. This was replicated for the perceptions of others, suggesting the BDD group internalised the belief that they should have a larger penis size. There was a significant correlation between symptoms of BDD and this discrepancy. This self-actual and self-ideal/self-should discrepancy and the role of comparing could be targeted in therapy.

RESUMEN

INTRODUCTION: Penis size is a huge topic of anxiety for a lot of men. Some of them are unhappy with their penis size as shown in the study conducted by Tiggemann in 2008. There are relatively few studies on erect penis size. This may reflect cultural taboos of researchers or doctors interacting with men who are in a state of sexual arousal. On the other hand, it is important for people who announce details on penis size to give the average penis size first and then sizes suggested by the researchers. METHODS: We performed a cross-sectional survey in the two major urban centres of the Democratic Republic of Congo namely Kinshasa and Lubumbashi over a period of two years from May 2014 to May 2016. A total of 21 information sources constituted our sample, 8 in Kinshasa and 13 in Lubumbashi. We found it sufficient because in our culture discussing about sexual matter is rare. The parameters studied were: the nature of the source, the accuracy of the measurement method, the presence of bibliographical reference, the announced penis size. RESULTS: The majority of information sources used were radio or television broadcastings (23,8%); this can be explained by the fact that there are an increasing number of radio and television stations in our country and especially in large cities. With regard to accuracy of information about penis measurement method when sharing the message about penis size, our study showed that the majority of information sources did not indicate it when they announced penis size to the public (85,7%). Several sources did not report bibliographical references (57,1%). Announced data analysis on penis size showed that the average penis size was: 14 cm (28,6%), 15 cm (23,8%) and 15-20 cm (19%). CONCLUSION: All these results are intended to offer a warning to all players responsible for diffusing information on sexual health (penis size): scientific rigor consists in seeking information from reliable sources.

RESUMEN

Penile dysmorphic disorder (PDD) is shorthand for men diagnosed with body dysmorphic disorder, in whom the size or shape of the penis is their main, if not their exclusive, preoccupation causing significant shame or handicap. There are no specific measures for identifying men with PDD compared to men who are anxious about the size of their penis but do not have PDD. Such a measure might be helpful for treatment planning, reducing unrealistic expectations, and measuring outcome after any psychological or physical intervention. Our aim was, therefore, to validate a specific measure, termed the Cosmetic Procedure Screening Scale for PDD (COPS-P). Eighty-one male participants were divided into three groups: a PDD group (n = 21), a small penis anxiety group (n = 37), and a control group (n = 23). All participants completed the COPS-P as well as standardized measures of depression, anxiety, social phobia, body image, quality of life, and erectile function. Penis size was also measured. The final COPS-P was based on nine items. The scale had good internal reliability and significant convergent validity with measures of related constructs. It discriminated between the PDD group, the small penis anxiety group, and the control group. This is the first study to develop a scale able to discriminate between those with PDD and men anxious about their size who did not have PDD. Clinicians and researchers may use the scale as part of an assessment for men presenting with anxiety about penis size and as an audit or outcome measure after any intervention for this population.

RESUMEN

Men with body dysmorphic disorder (BDD) may be preoccupied with the size or shape of the penis, which may be causing significant shame or impairment. Little is known about the characteristics and phenomenology of such men and whether they can be differentiated from men with small penis anxiety (SPA) (who do not have BDD), and men with no penile concerns. Twenty-six men with BDD, 31 men with SPA, and 33 men without penile concerns were compared on psychopathology, experiences of recurrent imagery, avoidance and safety-seeking behaviours. Men with BDD had significantly higher scores than both the SPA group and no penile concern group for measures of imagery, avoidance, safety seeking and general psychopathology. The groups differed on the phenomenology of BDD specific to penile size preoccupation clearly from the worries of SPA, which in turn were different to those of the men without concerns. The common avoidance and safety seeking behaviours were identified in such men that may be used clinically.

RESUMEN

INTRODUCTION: No measures are available for understanding beliefs in men who experience shame about the perceived size of their penis. Such a measure might be helpful for treatment planning, and measuring outcome after any psychological or physical intervention. AIM: Our aim was to validate a newly developed measure called the Beliefs about Penis Size Scale (BAPS). METHOD: One hundred seventy-three male participants completed a new questionnaire consisting of 18 items to be validated and developed into the BAPS, as well as various other standardized measures. A urologist also measured actual penis size. MAIN OUTCOME MEASURES: The BAPS was validated against six psychosexual self-report questionnaires as well as penile size measurements. RESULTS: Exploratory factor analysis reduced the number of items in the BAPS from 18 to 10, which was best explained by one factor. The 10-item BAPS had good internal consistency and correlated significantly with measures of depression, anxiety, body image quality of life, social anxiety, erectile function, overall satisfaction, and the importance attached to penis size. The BAPS was not found to correlate with actual penis size. It was able to discriminate between those who had concerns or were dissatisfied about their penis size and those who were not. CONCLUSIONS: This is the first study to develop a scale for measurement of beliefs about penis size. It may be used as part of an assessment for men who experience shame about the perceived size of their penis and as an outcome measure after treatment. The BAPS measures various manifestations of masculinity and shame about their perceived penis size including internal self-evaluative beliefs; negative evaluation by others; anticipated consequences of a perceived small penis, and extreme self-consciousness.

RESUMEN

INTRODUCTION: Penile size continues to receive popular and empirical attention. Little is known about the process of self-measurement and whether the behaviors a man engages in to become erect for self-measurement are associated with his erect penile dimensions. AIMS: The article aims to assess men's erect penile dimensions in a study in which the men would presumably be motivated to report accurate information about their penis size; and to explore associations between men's erect penile dimensions, their method of measurement, and their demographics. METHODS: Data are from an Internet-based baseline phase of a large prospective daily diary study that compared men's use of a standard-sized condom to men's use of a condom sized to fit their erect penis. MAIN OUTCOME MEASURES: The main outcomes are participant characteristics, activities engaged in during self-measurement process, and self-reported erect penile length and circumference. RESULTS: For this sample of 1,661 men, the mean erect penile length was 14.15 cm (SD = 2.66; range = 4 to 26 cm), and the mean erect penile circumference was 12.23 cm (SD = 2.23; range = 3 to 19). Participant characteristics were not associated with measured length or circumference. Most men measured their penis while alone, using hand stimulation to become erect. CONCLUSIONS: In this sample of men who measured their erect penile length and circumference for the purposes of receiving a condom sized to fit their erect penis, we found a mean erect penile length of 14.15 cm and a mean erect penile circumference of 12.23 cm. The self-reported erect penile dimensions in this study are consistent with other penile dimension research. Also, findings suggest that mode of getting an erection may influence erect penile dimensions. Additionally, how a man becomes erect for self-measurement may be associated with his erect penile length and/or circumference.

RESUMEN

BACKGROUND AND PURPOSE: What factors influence transgender men's decisions to undergo (and to not undergo) specific genital gender confirming surgeries (GCS) has not been described in the literature. Sexual function outcomes related to clitoral transposition and penile prosthesis placement is also not well described. Durability of neophallus dimensions after phalloplasty has not been described. A better understanding of these factors is necessary for pre-op counseling. We sought to assess patient genital-GCS related satisfaction, regret, pre/post-op sexual function, genital preferences, and genital measurements post-op. MATERIALS AND METHODS: We evaluated ten female to male transgender patients who had previously undergone suprapubic pedicle-flap phalloplasty [suprapubic phalloplasty (SP); N=10] and 15 who had undergone radial artery forearm-flap phalloplasty [(RAP); N=15; 5/15 without and 10/15 with cutaneous nerve to clitoral nerve anastomosis] at our center (UK). We queried patients' surgery related preferences and concerns, satisfaction, and sexual function pre/post-surgery, and accounted for whether patients had undergone clitoral transposition and/or cutaneous-to-clitoral nerve anastomosis. We measured flaccid and (where applicable) erect length and girth using a smart-phone app we designed. RESULTS: Mean age at surgery and follow-up for those that underwent SP was 35.1 and 2.23 years, and 34 and 6.8 for those that underwent RAP. Mean satisfaction scores were 9.1/10 and 9/10 for those that underwent SP and RAP, respectively. No patient (0%) regretted starting genital-GCS surgery. All (100%) patients that could achieve orgasm before GCS with clitoral transposition could achieve orgasm after surgery, and the vast majority reported preserved quality of erogenous sensation by our transposition technique. All (100%) RAP and 9/10 SP patients reported masturbation with their phallus. Inflatable penile prosthesis placement was not associated with decreased erogenous sensation/orgasm. Penile dimensions were relatively stable through follow-up for both groups. Our App length measurements correlated with a ruler within ±<4.5%. CONCLUSIONS: Female-to-male genital-GCS offered in 3-stages was associated with high overall satisfaction and no regret among our sample. Sexual function appears to be preserved after both clitoral transposition and inflatable prosthesis placement, and consolidation of erogenous sensation to the phallus was described as important to all subjects. Discussion of patient's pre-op sexual function, as well as specific concerns and preferences related to specific genital-GCS surgeries is important.
