A woman’s menstrual cycle will cause many changes in her body, and her sexual desire will also be affected. According to the British "Daily Mail" report on March 23, a new Canadian study found that women are more likely to have sexual fantasies during ovulation (about 14 days before their next menstrual period).

The research was led by Dr. Samantha Dawson of the University of Lethbridge in Canada. They conducted a study on 27 women aged 18-30. The participating women filled in a diary every day to record the number of sexual fantasies they had for a month. The results found that the participating women had about 0.77 sexual fantasies per day, but three days before and after ovulation, the number of sexual fantasies increased to 1.3 times, and the sexual fantasies more often involved men.

Dr. Dawson said that women’s ovulation period is the most fertile period. They look forward to sex more, so they have more sexual fantasies.
