International researchers have debunked the idea that a woman's face shape changes during menstruation, showing that there is no such thing as a menstrual mug after all. Previous research had shown changes in face shape over a women's menstrual cycle and suggested it may explain increased male attraction at peak fertility. The researchers replicated the previous experiment but with a more robust methodology, and did not find any significant changes in facial shape over the menstrual cycle, suggesting that the increase in facial attractiveness may be down to other cues such as skin colouration.

Menstrual cycles - Stability of women’s facial shape throughout the menstrual cycle
In this study, we tested previously found fluctuations in facial shape throughout the menstrual cycle. With methods more robust than those formerly used (larger sample size and detailed hormonal assessments determining the timing of the ovulation) we did not find significant changes in either of the three facial measurements conducted: symmetry, averageness and sexual dimorphism. Our results 1) suggest that the previously found increased facial attractiveness of women in the most fertile phase of the menstrual cycle is not driven by changes in facial shape, but might instead stem from other changes in facial appearance, such as a more attractive skin tone, 2) underline the importance of replication of studies with new methods
