In a sneak-peek for next week's episode of Keeping Up With The Kardashians, the mother-of-three is seen sharing the news with her sisters.
"Are you serious? You want another kid?" Kim, 37, asks.
"What if I do though? I don't know what I want," Kourtney, 38, explains. "What if I want a kid in the next 10 years? Wouldn't you rather have the insurance sitting there?"
Kim then asks Kourtney who she would want to have another child with.
"I don't know," Kourtney smiles. "She does, look at that smile," Khloe, who is pregnant with her first child, says.
"Wouldn't you just say, ‘Hey, Scott, give me your sperm.' And they take it in a turkey baster and they stick it up you and [squeeze]," Kim says, referring to the father of Kourtney's three kids.
"I don't need a baby to have a baby, I have three kids," Kourtney explains. "I'm saying if I am like in love and the person wants to have a kid…"
"So you're thinking about a younger guy," Khloe says, referencing Kourtney's boyfriend, Younes Bendjima.
Kourtney replies, "If I wanted to have it with my situation right this second I would take out my IUD and I would get to work. Right now I'm good."
"This is if you're in love and want to fulfill man's dream of a baby," Khloe, 33, suggests
"Yep. What if I want my love to come into the world?" Kourtney replies.
