Carrozza's comments came Friday in an interview with Radio 24, Italy's ANSA news agency reported.
"At 70 university professors should retire, and would want to do it if they were generous and honest, and go ahead with offering free seminars, mentoring students or donating their personal libraries to universities," Carrozza said.
Professors who stay at their posts past age 70 "offend their university and offend the young," Carrozza said.
"At a time of sacrifice for all, there is even more reason for those who are over 70 to make a sacrifice, given that they have received so much from this world," Carrozza said.
