John Bercow was at risk of becoming the non-Speaker due to a croaky voice.
The Commons Speaker has become known for his booming delivery, turn of phrase and bellowing of “Order!” while overseeing matters in the chamber.
But MPs expressed concern for him during digital, culture, media and sport questions.
After his raspy voice introduced the session, Mr Bercow noted: “It won’t last long, don’t worry.”
Culture Secretary Nicky Morgan said: “I hope your voice is fully recovered very soon.”
Conservative former minister Tim Loughton added: “I have Strepsils.”
Mr Bercow later drew laughter from the Prime Minister and other MPs when he made reference to Boris Johnson’s speech at the Tory Party conference.
Mr Johnson said on Wednesday: “If Parliament were a reality TV show then the whole lot of us I’m afraid would have been voted out of the jungle by now.
“But at least we would have the consolation of a Speaker being forced to eat a kangaroo testicle.”
He said: “I just wanted to take the opportunity to confirm to the House that the state of my throat – which is purely temporary – is not down to the consumption of a kangaroo’s testicle.
“I wouldn’t eat it, it would probably be poisoned.”
Mr Bercow is in his final weeks in the role of Speaker after announcing he will chair proceedings for the final time on October 31 – the current Brexit deadline – and also step down as MP for Buckingham.
He has been in the role since June 2009 and the election to replace him will take place on November 4.
