尽管周期阶段对女性嗅觉阈值有显著影响,但关于辨别和识别的数据有限。因此,我们调查了更广泛的嗅觉表现,并分析了周期阶段和口服避孕药的影响。我们测量了80名健康的高加索人,其中20名服用口服避孕药的女性和40名未服用口服避孕药的女性进一步分为卵泡期和黄体期。所有参与者的嗅觉表现都被评估了两次,使用的是“嗅觉棒”电池,并收集了正丁醇的强度和愉悦感评级。数据分析显示,女性在气味辨别和气味识别方面优于男性。在黄体期,正丁醇出现了更高的阈值和更高的强度等级。口服避孕药的持续时间与嗅觉表现呈正相关,表明口服避孕药的时间越长,嗅觉表现越好。因此,我们的数据表明,气味表现受到月经周期阶段和口服避孕药摄入持续时间的影响,因此可以受到激素变化的调节。
Although a significant impact of cycle phase on olfactory thresholds has been shown in females, limited data exist regarding discrimination and identification. Therefore, we investigated a broader range of olfactory performance and analyzed the impact of cycle phase and oral contraception. We measured 80 healthy Caucasians, including 20 females taking oral contraceptives and 40 females without oral contraception who were further divided into follicular and luteal phase. Olfactory performance of all participants was assessed twice using the “Sniffin’ Sticks” battery and intensity and pleasantness ratings of n-butanol were collected. Data analysis revealed that females outperformed males in odor discrimination and odor identification. In the luteal phase, higher thresholds and higher intensity ratings for n-butanol emerged. Duration of oral contraception correlated positively with olfactory performance pointing to better performance with longer intake. Hence, our data show that odor performance is affected by menstrual cycle phase and duration of oral contraception intake and thus can be modulated by hormonal changes.
