Researchers at Japan's Kyoto University have conducted an unusual study which has found that women who have just finished ovulating manage to spot snakes quicker than other women.
Around 60 women in different stages of their menstrual cycle took part in the study. The participants were shown nine different pictures of flowers, only one of which had a snake in it. The researchers then tabulated how quickly the participants were able to spot the snake.
The researchers found that those who had just finished ovulating, or were in the luteal phase of their menstrual cycle, managed to spot the snake faster than other volunteers.
