Each week Dr. Karl Kruszelnicki hosts a radio show on the Australian Triple J. station.
The 70-year-old author and science commentator answers – What's up?
Normally he's brilliant at explaining weird and wacky things.
A woman called into the show, with a very personal question for Dr. Karl regarding her sex life.
And it turned out her dilemma was rather niche.
She wanted to know why she was giving up her husband's oral sex, she went on a deaf day.
The lady went on to explain that if her husband's penis hit the back of her throat, she would lose her hearing for a while while.
Unsurprisingly Dr. Karl struggled to find a suitable answer for her
But it turns out that a lot of woman have also experienced something similar.
Speaking to news.com.au Dr. Karl said: "So I asked my girlfriends if they experienced it with their partners and it happened to them too."
So he decided to dig deeper and work out what could happen to him – and eventually he came up with an explanation.
"What I'm suggesting is that the penis pushing against the back of the throat pushes against the Eustachian tube and closes it off.
"It compresses the air on the inner side of the eardrum, so it's not so easy to push the airwaves. it's so you go on a deaf day, "he said.
"That's my theory."
