Kim Kardashian and Kanye West are considering using a surrogate in hopes of having a second child.

According to HollywoodLife.com, during a recent episode of "Keeping Up With The Kardashians" reality show, Kardashian admited that she's open to using a surrogate in hopes of adding a young brother or sister for daughter North.

The 34-year-old Kardashian recently boasted her and West were having sex "500 times a day" in hopes of adding to their family. Still, the website adds Kardashian and her 37-year-old husband have been having fertility issues for quite some time.

Since giving birth to her daughter nearly two years ago, Kardashian has been flaunting her post-baby body and recently completely posed nude for a photo shoot.

The New York Daily News reports Kardashian recently said, "I remember growing up being so close with my sisters, so I want siblings for North. Because it's been so tough I'm seeing a fertility doctor."

Soon after returning from attending Fashion Week in Paris, Kardashian was seen leaving a fertility in Los Angeles.

"I am so on a mission to get pregnant," she told her fertility doctor during a Season 10 episode of KUWTK.

Later in that same episode, Kardashian said, "The doctor said when I have sex I have to lay down for, like, 10-20 minutes, so, I just had sex before you guys got here."

She later adds, "Because it's been so tough I'm seeing a fertility doctor to see, like, exactly when I'm ovulating and really increase my odds of getting pregnant naturally. The doctor said when I have sex I have to lay down for, like, 10-20 minutes, so, I just had sex before you guys got here."
