Unless you've had your head under a rock, you know that Kim Kardashian and Kanye West have been having problems getting pregnant again. After a year of being unsuccessful, the celeb couple is now trying other avenues than having sex "500 times a day" -- and the duo is now exploring surrogacy, reports Us Weekly.

The couple, who just celebrated their first wedding anniversary together, are trying in vitro fertilization.

"Kim has been undergoing IVF," an insider tells Us. The 34-year-old reality star and the rapper have a 23-month-old daughter but the delivery was dramatic and took a toll on Kim's body.

In a recent episode of Keeping Up With the Kardashians, the star underwent a procedure to "clear something out of [her] uterus." In an upcoming episode, Kim reveals that an implanted embryo did not take.

Last month, Kim did talk about the struggle on the Today show. "I would like to hold out a little bit longer, and still try," she told Lauer. "I still have hope, so I'm just going to keep on trying. Never say never. I mean, we haven't talked about adopting."

We hope the A-list couple has some luck. Nori is pretty much the cutest kid around town -- we'd love to see another Kimye collab!
