A very high number of women have started to freeze their eggs as they are unable to find an equally intelligent partner.
In a study by researchers at Yale University, it found that fewer men are entering higher education, and therefore, educated women are finding it difficult to find their perfect partner.
According to The Independent, there is an "over-supply" of highly educated females, and the intelligence gap between men and women is becoming wider.
The study examined 150 women in the US and Israel, who have had their eggs frozen throughout eight clinics.
90 per cent of them said that they were "preserving" their eggs because they have not found a partner yet.
81 per cent of the women said they have a college degree.
Author of the study, Professor of Anthropology Marcia Ihorn, said: "There is a major gap – they are literally missing men.
"There are not enough college graduates for them. In simple terms, this is about an over-supply of educated women."
To further that, a fertility doctor who took part in the study explained: "[Straight] women tell us frequently that they are freezing their eggs because the men they meet feel threatened by their success and so are unwilling to commit to starting a family together."
