We describe here the sexual histories and characteristics of 338 individuals with interests in castration (orchiectomy) and, more broadly, genital ablation (i.e., orchiectomy, penectomy, and/or nullification), recruited from the Eunuch Archive. We compared four groups: those who only fantasize about castration (Fantasy, n = 66), those who wish to be castrated in the future (Aspiring, n = 166), and those who have been castrated (Eunuchs) both with (n = 42) or without (n = 64) androgen replacement therapy (ART). In our sample, 35.6–53.8% had sexual fantasies of castrating someone, 83.3–90.8% had fantasies of being castrated, 20.6–33.3% had fantasies of removing someone’s penis, and 45.3–61.9% had fantasies of having a penectomy. The four groups had similar arousal by high-risk sex behaviors, anal sex play, attraction to people under 18, common sex behaviors, and fetishistic behaviors. Fantasy of being castrated by someone was associated with elevated high-risk sexual behaviors and attraction to individuals aged 18 to 49 after controlling for age, groups, and sexual attraction. In addition, after adjusting for age, groups, and sexual attraction, fantasy of castrating someone was associated with more attraction to individuals under the age of 18 and being aroused by interaction with a stranger, whereas fantasy of cutting off someone’s penis was associated with less tendency for common sexual behaviors and digital sex communication. Fantasy of being penectomized was associated with high risk and fetishistic sexual behaviors. These results support screening for high-risk behaviors in individuals who endorse an interest in genital ablation, with treatments focused on harm reduction.

我们在此描述了从太监档案馆招募的 338 名对阉割（睾丸切除术）以及更广泛的生殖器切除（即睾丸切除术、阴茎切除术和/或废止）感兴趣的个体的性历史和特征。我们比较了四组：那些只幻想阉割的人（幻想，n = 66），那些希望将来被阉割的人（Aspiring，n = 166），以及那些已经被阉割的人（太监），两者都具有（n = 42) 或没有 (n = 64) 雄激素替代疗法 (ART)。在我们的样本中，35.6-53.8%的人有阉割某人的性幻想，83.3-90.8%的人有被阉割的幻想，20.6-33.3%的人有切除某人阴茎的幻想，45.3-61.9%的人有阴茎切除术的幻想。这四组人对高风险性行为、肛交游戏、对 18 岁以下的人的吸引力、常见性行为和恋物癖行为的唤醒程度相似。在控制年龄、群体和性吸引力后，被某人阉割的幻想与高风险性行为和对 18 至 49 岁个体的吸引力增加有关。此外，在调整了年龄、群体和性吸引力后，阉割某人的幻想与 18 岁以下的个人更具吸引力以及通过与陌生人互动而被唤起相关，而切断某人的阴茎的幻想则与较少的吸引力相关。常见性行为和数字性交流的倾向。幻想被切除阴茎与高风险和恋物癖性行为有关。这些结果支持对那些支持生殖器切除感兴趣的个体进行高风险行为筛查，并以减少伤害为重点的治疗。
