Refusing to tell him what had happened until he agreed to be her husband, the woman popped the question anyway before rushing to hospital where Dr Kay treated her.
'Equal parts unexpected, disgusting and romantic'
Dr Kay described the proposal as "equal parts unexpected, disgusting and I suppose, romantic."
Although the woman's boyfriend tried to remove the egg from her intimate area, "no amount of shoogling from either of them would get this particular goose to lay her golden egg.
"Remarkably, she was so keen to maintain the surprise she wouldn't tell him what she'd done or why," Dr Kay added.
Once at hospital, Dr Kay managed to remove the egg with forceps and the woman is thought to have made a full recovery.
