家庭组成（例如，没有父亲）与女性的青春期时间有关，尽管人类灵长类动物的社会内分泌学知之甚少。为了更好地了解社会对性成熟的影响，我们从大约1938名大学生中收集了月经初潮年龄和家庭组成的回顾性数据。没有亲生父亲、有同父异母和同父异母兄弟，以及生活在城市环境中，都与月经初潮提前有关。在成长过程中，家里有姐妹，尤其是姐姐，与月经初潮推迟有关。月经初潮年龄不受家庭中兄弟数量的影响，也不受出生顺序的影响。体重和种族也与月经初潮有关。目前的研究结果促进了文献的发展，因为它们暗示了人类信息素可以调节性成熟，促进基因存活，防止近亲繁殖，就像啮齿动物和非人灵长类动物一样。
Family composition (e.g., the absence of a father) is associated with pubertal timing in women, although the socioendocrinology of the human primate is poorly understood. To better understand social influences on sexual maturation, retrospective data were collected on menarcheal age and family composition from a sample of approximately 1,938 participants from a college population. Absence of a biological father, the presence of half- and step-brothers, and living in an urban environment were associated with earlier menarche. The presence of sisters in the household while growing up, especially older sisters, was associated with delayed menarche. Menarcheal age was not affected by number of brothers in the household, nor was there an effect of birth order. Body weight and race were also associated with menarche. The present findings advance the literature as they are suggestive of putative human pheromones that modulate sexual maturation to promote gene survival and prevent inbreeding, as occurs in rodents and nonhuman primates.
