Human body morphology is thought to be correlated with sexual behaviour and sociosexuality (defined as an increased willingness to engage in sex without commitment) influences the perception of certain cues of physical attractiveness. Based on a sample of Slovak university students, we investigated relationships between 1) male and female mating success and reported body morphology (body mass index, BMI and waist-to-hip ratio, WHR) and 2) mate preference characteristics and mating success. Both males and females reported a similar number of long-term sexual partners and frequency of engaging in extra-pair copulation (EPC). The mating success of both sexes was positively mediated by self-perceived attractiveness. However, female BMI was inversely associated with mating success whereas increasing BMI was positively associated with male mating success (the total number of lifetime sexual partners) as well as with the likelihood of engaging in EPC. Unrestricted sociosexuality positively correlated with direct and indirect benefits from mating and negatively with the religious/political background of a potential mate and with the desire for a home/ children. These results confirm the hypothesis that human body morphology is associated with sexual behaviour and that cues of direct/indirect benefits in a potential mate positively correlate with sociosexuality.
人体形态被认为与性行为相关，而社会性取向（定义为在无承诺情况下增加性行为的意愿）会影响对某些身体吸引力线索的认知。基于斯洛伐克大学生样本，我们研究了以下关系：1）男性和女性的交配成功率与报告的身体形态（体重指数，BMI和腰臀比，WHR）之间的关系，以及2）配偶偏好特征与交配成功率之间的关系。男性和女性报告的长期性伴侣数量以及参与婚外交配（EPC）的频率相似。两性的交配成功率都由自我感知的吸引力正向介导。然而，女性的BMI与交配成功率呈负相关，而BMI的增加与男性交配成功率（终身性伴侣总数）以及参与EPC的可能性呈正相关。不受限制的社会性取向与交配的直接和间接益处呈正相关，与潜在配偶的宗教/政治背景以及对家庭/孩子的渴望呈负相关。这些结果证实了以下假设：人体形态与性行为相关，潜在配偶的直接/间接益处线索与社会性取向呈正相关。
