A couple conceived their 16-month old son, while one of the partners was asleep, reported the Huffington Post.
Ryan Harris, 28, has a rare medical condition called sexsomnia, in which you perform sexual acts in your sleep, but cannot remember them later, reported the Sun.
Dee Harris, 25, said that Ryan wakes her up for sex regularly, but doesn't fully gain consciousness himself, reported the Sun.
Dee said it was clear that she conceived Lincoln, their son, on a night when they had "sleep sex."
According to the Sun, the couple has been together for nine years.
