Some 46% of girls enter higher education compared with just 36% of boys.
Oxford University researchers found that even in Year Nine, when pupils are 13 or 14, girls had more positive attitudes towards university than boys.
The statistics may explain the growing disparity in university admissions between the sexes.
Girls born in 2016 will be 75% more likely to study for a degree than their male classmates if action is not taken to address a growing university gender gap, according to a report issued last month.
And aspiring to go on to higher education by 15 or 16 makes a big difference to A-level choices, the latest study published by The Sutton Trust showed.
Data from 3,000 young people found that almost 65% of girls in Year Nine thought it very important to go to university, compared with 58% of boys, the Press Association reported.
Over half of all the Year Nine pupils surveyed (61%) thought it was very important to get a degree, compared with only 13% who said it was of little or very little importance.
Around one in 10 girls felt it was not important to get a degree, but among boys the proportion declaring university of little importance was 15%.
Pupils aged 15 and 16 with similar GCSE results were twice as likely to go on to do three A-levels if they saw university as a likely goal for them and Professor Kathy Sylva, the report’s co-author, said this could explain the gap in admissions later.
She said: “The higher aspirations of girls in comparison to boys may be linked to their greater A-level success and gaining admission to university.”
The report also found that disadvantaged students were less likely to think they would go on to university, with only 27% having high aspirations compared with 39% of their better-off peers.
The chief executive of The Sutton Trust, a foundation which promotes social mobility, called on schools to raise pupils’ aspirations.
Sir Peter Lampl said: “We need to offer more support to disadvantaged young people throughout their education so that they are in a position to fulfil their potential after GCSE.”
