Reality star Kim Kardashian may have found a solution to her fertility problems after her mother Kris Jenner suggested that her older sister Kourtney Kardashian becomes a surrogate to carry her second baby.

The 34-year-old has been struggling to conceive her second child with husband Kanye West for several months and, in the latest episode of Keeping Up With The Kardashians, sought professional advice from a doctor.

At the medical facility, Kardashian is told that she must have an operation to remove parts of her placenta that became stuck to her uterus when she gave birth to daughter North in June 2013.

Discussing the option of using a surrogate mother to carry the child, momager Jenner suggested: "Kourtney would probably do it." However, Kardashian replied: "To have a surrogate is really scary to me. I don't want one. I wouldn't dare ask anyone to do that for me."

When her younger sister Kendall Jenner asked about the possibility of a surrogate, Kardashian said: "What if they're like a lunatic? I'm going to have to have security around them.

"What if they run off with my baby and go raise my baby in a different country? I would only do that if I couldn't carry another one."

The E! reality star's struggles during her first pregnancy were well-documented on the show, but in the latest episode, she admits it was worth it in the end.

"Trying for baby number two is not fun like baby number one. I'm like 'I'm ovulating in five minutes, get over here'. It's crazy because I had such an easy delivery, but right after you deliver the baby lives in this sac – the placenta – then you kind of give birth to that and it just kind of comes out. Mine went right back in me because it was stuck to a part of my uterus that it grew into," she explained.

"I complained so much about how much I hated being pregnant and I never thought I would be begging to be pregnant,' she told sister Kendall Jenner and pal Jonathan Cheban."

Kourtney, 35, already shares three children with partner Scott Disick: son Mason, five; daughter Penelope, two; and son Reign, who was born in December 2014.
