Abstract：
Male genital self-image (GSI) refers to how men feel about their genitals. Studies suggest that GSI is influenced by several psychosocial and physical factors, such as frequency of sexual activities, anxiety, and sexual dysfunctions. In Brazil, no studies have investigated the factors associated with satisfaction with male GSI. This is a cross-sectional and online study conducted with Brazilian men over 18 years of age. The Male Genital Self-Image Scale (MGSIS), Body Appreciation Scale-2 (BAS-2), and International Index of Erectile Function (IIEF) were used. Body appreciation and frequency of sexual activity were included as confirmatory variables and other variables were explored as factors associated with GSI. Data were analyzed by binary logistic and multiple linear regression, according to the MGSIS cut-off point for satisfaction with male GSI and total score of MGSIS, respectively. A total of 1,235 men (M = 26.14, SD = 7.28 years) participated in the study. The mean of the total MGSIS score was 23.02 (SD = 4.45; absolute range, 7-28) points, with 62.11% of men being classified as satisfied with GSI. Men satisfied with GSI were more likely to have a partner, higher body appreciation, lower body mass index (BMI), and not have phimosis (excess skin covering the penis, making it difficult to expose the glans). Satisfaction with GSI of Brazilian men was associated with relationship status, body appreciation, BMI, and phimosis.
摘要：
男性生殖器自我形象（GSI）是指男性对生殖器的感觉。研究表明，GSI受多种心理社会和身体因素的影响，比如性活动的频率，焦虑,和性功能障碍。在巴西,没有研究调查与男性GSI满意度相关的因素.这是一项针对18岁以上巴西男性的横断面和在线研究。男性生殖器自我形象量表（MGSIS），身体欣赏量表-2（BAS-2），使用国际勃起功能指数(IIEF)。将身体欣赏和性活动频率作为确认变量，并探索其他变量作为与GSI相关的因素。数据采用二元逻辑回归和多元线性回归分析，根据男性GSI满意度的MGSIS分界点和MGSIS总分，分别。共有1,235名男性（M=26.14，SD=7.28岁）参加了这项研究。MGSIS总分的平均值为23.02（SD=4.45；绝对范围，7-28）分，62.11%的男性被归类为对GSI满意。对GSI满意的男性更有可能有伴侣，更高的身体欣赏，较低的体重指数（BMI），并且没有包茎（覆盖阴茎的多余皮肤，使其难以暴露龟头)。巴西男性对GSI的满意度与关系状态有关，身体欣赏,BMI,和包茎。
