In a TV show, in which Khloe appeared with her sisters Kim and Kourtney, the 28-year-old said that she never knew getting pregnant was so difficult, reported Contactmusic.
"My mum has so many kids, and Kourtney pops them out like a PEZ dispenser, so you think it's, like, so easy. You realise it's not as easy as you might think," Khloe said.
Kourtney has a son, Mason, two, and a daughter, Penelope, two months, with partner Scott Disick.
In an episode of the reality show 'Keeping Up With the Kardashians', Khloe visited a fertility Clinic with Kim.
Khloe said that learning about a woman's body along with viewers was tough.
"It was really hard to show what I was going through. I feel like I'm helping a lot of people, but I'm still figuring it out for myself," she said.
Khloe, who married her basketball player partner in September 2009 after a one-month engagement, has continued to undergo fertility treatments in hope of one day starting a family.
