Duterte, in remarks last week to a crowd that included about 200 former rebels, suggested his soldiers be given new orders from "the mayor".
"'We will not kill you".
It's been one inflammatory comment after another from Duterte, who has been frequently compared to US President Donald Trump for his penchant to say exactly what runs through his head. He then said that women are "useless" without their vaginas.
In its official transcript of the speech, Duterte's communication office replaced the word "vagina" with a dash. "Come on. Just laugh", said presidential spokesperson Harry Roque in a video posted to social media.
Duterte claimed in November 2017 that he had killed someone in a stabbing by the time he was 16-years-old, but his aides have claimed that he is prone to "hyperboles".

She said Duterte was taking "state terrorism against women to a whole new level" and "further confirms himself as the most risky macho-fascist in the government right now".
Recently, the International Criminal Court also said it was starting a preliminary examination into hundreds of alleged extrajudicial killings Duterte is accused of ordering from when he was mayor of Davao City to the beginning of the "war against drugs" he began waging on becoming president.
He later apologised and said he did not intend to disrespect women.
Left-wing group Karapatan said Rodrigo Duterte "has distinguished himself as a frothing-in-the-mouth fascist who incites the worst violations of worldwide humanitarian law".
With crime easing and recent public surveys showing satisfaction with Duterte's administration, the president's opponents may do better if they focus on issues such as traffic jams in the capital and rising rice prices, he said.
This is not the first lewd remark of Duterte against women.
His comments gained intense criticism from human rights agencies, who called them "misogynist, derogatory and demeaning statements".
