Previous studies of reproductive state and olfactory sensitivity in women have not directly compared thresholds for social and environmental odors. Here, we used successive dilutions presented in a staircase protocol to determine olfactory thresholds for androstadienone, a social odor produced by men, and rose, an environmental odor signaling a source of micronutrients essential for successful implantation, prenatal development and maternal health. Fertile women were more sensitive to the social than the environmental odor, while women using oral contraceptives, a non-fertile hormonal state similar to early pregnancy, were more sensitive to the environmental odor. This preliminary study sets the stage for further work on the interaction between hormonal states and sensitivity to specific odors with reproductive significance.
以往关于女性生殖状态与嗅觉敏感性的研究并未直接比较社交气味和环境气味的阈值。在此，我们采用阶梯式方案呈现的连续稀释法，来确定雄二烯酮（一种由男性产生的社交气味）和玫瑰气味（一种环境气味，表明存在对成功着床、产前发育和母体健康至关重要的微量营养素来源）的嗅觉阈值。处于生育期的女性对社交气味比环境气味更敏感，而使用口服避孕药的女性（一种类似于早孕的非生育激素状态）对环境气味更敏感。这项初步研究为进一步研究激素状态与对具有生殖意义的特定气味的敏感性之间的相互作用奠定了基础。
