Previous research indicates human body odor (BO) can signal kinship, sickness and genetic compatibility. Based on research indicating single males have higher testosterone levels than partnered males and that higher testosterone levels are associated with stronger smelling BO, the current study aimed to determine if, by extension of previous findings, single males' BO smells stronger than partnered males' BO. Eighty-two heterosexual women aged 18-35 years rated the BO and faces of six different males also aged 18-35 years. Consistent with the hypothesis, single men's BO smelled stronger than partnered men's BO and single men's faces were rated as more masculine than partnered men's faces. The possible advantages of females being able to identify single males are addressed in the Discussion.
先前的研究表明，人体气味（BO）能够传递亲属关系、疾病和基因兼容性等信息。基于研究显示单身男性的睾酮水平高于有伴侣的男性，且较高的睾酮水平与气味更浓烈的体香相关，本研究旨在确定，根据先前的研究结果推断，单身男性的体香是否比有伴侣男性的体香更浓烈。82名年龄在18至35岁之间的异性恋女性对6名同样年龄在18至35岁之间的不同男性的体香和面部进行了评分。与假设一致，单身男性的体香比有伴侣男性的体香闻起来更浓烈，且单身男性的面部被评为比有伴侣男性的面部更具阳刚之气。讨论部分探讨了女性能够识别单身男性可能带来的优势。
