A government survey showed on Tuesday that men passed entrance exams more than women at nearly 80 percent of medical schools polled after a medical university in Tokyo admitted last month to altering exam scores to limit the enrollment of female students.

Of 81 medical schools surveyed, men have passed entrance exams more than women at 63 schools over the past six years, while women got through such exams more than men at 17 schools. The 81 medical schools include Tokyo Women's Medical University.

The education ministry released the preliminary results of the survey after Tokyo Medical University admitted to unfairly lowering the scores of women applicants to curb their enrollment. The misconduct was severely criticized as gender discrimination.
