*After Octo-Mom, Nadya Sulema, did it, you’d think no one would want in-vitro fertilization.

Well, think again. Khloe Kardashian isn’t going to wait any longer to try to conceive a child naturally. She and husband, Lamar Odom, are moving along with the procedure.

“She is desperate for a baby with Lamar and will do whatever it takes,” a friend of the couple told Us Weekly magazine. “They have faith the IVF will work.” The reality star has even started consultations as well as consumption of pre-natal vitamins

The couple, which has been married for two years, has been very public about wanting to start/expand their family. Lamar has two children from a previous relationship.

Since nothing has been working for the couple, this is the route they’ll go. And Khloe seems especially desperate since her sister Kourtney, is expecting her second child with boyfriend Scott Disick.

“She’s thrilled for Kourtney, but she’s really sensitive,” another source said. “And it’s hard to see your sister get something you want so badly.”
