The prosecution has requested Dominique Pelicot be sentenced to prison for 20 years for drugging and raping his then wife Gisèle Pelicot and recruiting dozens of others to rape her for nearly a decade.
"The maximum sentence is 20 years, which is a lot... but at the same time ... too little in view of the seriousness of the acts that were committed and repeated", Laure Chabaud, one of the two public prosecutors, told the court in the southern city of Avignon on Monday.
Dominique Pelicot has admitted to drugging his wife and recruting dozens of men online over a decade to rape her while she lay unconscious in their home in Mazan, Provence.
Despite video evidence against the other 50 men on trial, only 14 of them have admitted rape.
The others have said they did not realise they were raping her, did not intend to rape her or put all the blame on her husband, whom they said had manipulated them.
In her closing statements, 72-year-old Gisèle Pelicot said the case has laid bare a "macho society" in which rape is "trivialised".

The 11-week trial, which has prompted demonstrations in France and attracted worldwide attention, has turned into an examination of the pervasiveness of sexual violence.
Public prosecutor Jean-François Mayet told the court on Monday that what's at stake in the Mazan trial is to "fundamentally change the relationship between men and women...not a conviction or an acquittal".
Mayet praised the "courage" and "dignity" of Gisèle Pelicot and thanked her for allowing hearings to be held in public and allowing some of the approximately 20,000 photos and videos taken without her knowledge by Dominique Pelicot to be shown.
"You were right, madam: the past few weeks have shown the importance of showing this, so that shame changes sides," he added.
The court is expected to deliver its verdicts before 20 December.
