A recent study conducted by researchers from University of Lethbridge in Canada has found that women were more likely to indulge in sexual fantasies during their most fertile period of their menstrual cycle.
The researchers surveyed around 27 heterosexual women aged between 18 and 30 years and who were not in any relationship or on hormonal birth control. The participants were asked to maintain an online diary, noting down their sexual fantasies every day for one month.
The researchers found that on average, the women had 0.77 sexual fantasies a day but this increased to 1.3 fantasies per day during the three-day period of ovulation. The increased sexual fantasies were also accompanied by a greater number of men in the fantasies.
"I wanted to study fantasies because they are not constrained by the presence or absence of a partner, so the increase in fantasies and also the increase in how arousing those fantasies were is a reflection of this increased interest in sex mid-cycle", lead researcher Samantha Dawson said.
