To describe phalloplasty subunits and determine the preferred crowdsourced esthetics. Esthetic ideals are often used to guide reconstruction, and there has been an increase in the number of gender-affirming surgeries and reconstructive phalloplasties performed. However, there is a paucity of literature describing ideal phalloplasty esthetics.
Phallus esthetic subunits were defined, and a split testing-based survey was used. Subjects were solicited via Craigslist, Amazon Mechanical Turk, and Reddit and distributed among health care co-workers. Computer-generated images with variable ratios of glans, corona, and shaft were provided and respondents were asked to select the most esthetically pleasing photo. Demographic information was gathered. Univariate and multivariate regression were performed.
A total of 1029 people responded to the survey request and 909 people (88.3%) completed the entire survey. There were 440 respondents who self-identified as male, 334 female, 92 transgender male, and 25 transgender female. The health care field was the profession for 55.4%. Health care providers had 65.3% higher odds of preferring the longer shaft length-to-width ratio, 30.3% less odds of preferring a bilateral taper of the glans, and 48.4% less odds of preferring an angulated shaft compared to non-health care providers (P = .006, P = .021, P <.001, respectively). When compared to males, transgender females were more than 13 times likely to prefer an angulated glans corona junction (P = .008).
The ideal phallic esthetic varies by individual, and there were statistically significant preferences across age, education, health care status, gender, and sexual orientation. This study can serve as a guide on phalloplasties for patients and gender-affirming surgeons.
描述阴茎成形亚单位，并确定首选的众包美学。审美理想常被用来指导重建，并且进行性别肯定手术和重建性阴茎成形术的数量有所增加。然而，描述理想的阴茎成形术美学的文献很少。
定义了阴茎美学亚单位，并使用基于拆分测试的调查。通过 Craigslist、Amazon Mechanical Turk 和 Reddit 招募受试者，并分发给医疗保健同事。提供了具有不同龟头、冠状沟和阴茎干比例的计算机生成图像，要求受访者选择最具美感的照片。收集人口统计学信息。进行单变量和多变量回归。
共有 1029 人对调查请求做出回应，其中 909 人（88.3%）完成了整个调查。有 440 名受访者自我认同为男性，334 名女性，92 名跨性别男性，25 名跨性别女性。医疗保健领域是 55.4%的人的职业。与非医疗保健提供者相比，医疗保健提供者更喜欢更长的阴茎干长径比的可能性高 65.3%，更喜欢龟头双侧逐渐变细的可能性低 30.3%，更喜欢成角阴茎的可能性低 48.4%（P =.006，P =.021，P<.001，分别）。与男性相比，跨性别女性更喜欢成角的龟头冠状沟交界处的可能性高 13 倍以上（P =.008）。
理想的阴茎美学因人而异，并且在年龄、教育、医疗保健状况、性别和性取向方面存在统计学上显著的偏好。本研究可为患者和性别肯定外科医生提供阴茎成形术指南。
