The objective of the present study is to investigate gender differences in the ability to identify females' voice during menstruation. In Study 1, 55 male participants (M age = 19.6 years, SD = 1.0) were asked to listen to vocal samples from women during both ovulation and menstruation and to identify which recordings featured menstruating women. The results showed that the accuracy of men's responses (M = 56.73%, SD = 0.21) was significantly higher than 50%. In Study 2, 118 female students (M age = 19.4 years, SD = 1.6) completed the same task. The results indicated that the accuracy of women's performance was nearly 50%. These preliminary findings suggest that men are better able to identify women's voices during menstruation than women. Future work could consider several significant variables for the purpose of validating the results.
