國際期刊《行為學》（Ethology）3月刊上刊登的一項研究指出,，男人能分辨出女性聲音的微小變化，排卵期時,，女人的聲音對男性最具吸引力,。
每個月，女人的身體都會隨著生理周期的變化出現(xiàn)一些微妙轉(zhuǎn)變,，就連聲音也不例外,。
美國亞當斯州立學院的心理學家內(nèi)森·皮托內(nèi)和紐約州立大學奧爾巴尼分校的戈登·蓋洛普教授共同進行了這項研究。他們對10位女性進行了錄音,，每人4段,，分別來自于完整月經(jīng)周期的不同時間段，如排卵期,、安全期,、月經(jīng)來潮時等。之后三組男性分別聽這些錄音,，并且給出評價,。結(jié)果發(fā)現(xiàn)，同一個女人,，在排卵期與月經(jīng)期的聲音獲得的評價大不相同,，對男人的吸引力也不同。在男人看來，女人排卵期時聲音最動聽,，月經(jīng)期則最不能吸引他,。
此外,，也有研究顯示,，男性通常會在潛意識中判斷女性的生理周期。例如在歌廳中,，演唱者在排卵期時獲得的小費會比月經(jīng)期時的小費高80%,。
研究者分析，月經(jīng)期的女性體內(nèi)的雌性激素變化會導致聲音的細微改變,，“一個人的聲音中會攜帶大量與繁殖有關(guān)的信息,，這是人類進化的結(jié)果。”(生物谷 Bioon.com)

The Unique Impact of Menstruation on the Female Voice: Implications for the Evolution of Menstrual Cycle Cues
R. Nathan Pipitone, Gordon G. Gallup Jr
Research shows that hormonal changes in women across the menstrual cycle affect vocal production. Most work has documented shifts at high fertility times (i.e., ovulation) or during premenstruation. However, hormonal changes at menstruation also affect female physiology and behavior and could affect vocal production. The present studies investigated perceptual differences in voices recorded during menstruation compared with recordings taken at other times of the menstrual cycle. Results show that male raters could reliably identify voices recorded during menstruation with or without the presence of a voice recorded closest to ovulation. In addition, voices recorded at menstruation were identified as being the most unattractive. These findings indicate that voice recordings taken at times of lowest fertility may uniquely impact women’s vocal production and that perceptions of voice based on cycle phase are not specific to the time of heightened fertility. Implications for the evolution of human menstrual cycle cues are discussed.
