Nick and Mariah are Trying Fertility Treatments to Get Pregnant

Apparently the regular in-and-out when it comes to baby-making isn't working in the Carey/Cannon household.

According to sources, Mariah Carey and Nick Cannon visited the Southern California Reproductive Center o Feb. 19. The Center is one of the world's most highly-regarded fertility clinics and specializes in In Vitro Fertilization (which is the process of fertilization by manually combining an egg and sperm in a Petri dish). Jennifer Lopez, Nicole Richie and Rob Lowe and his wife all used this clinic.

Friends told the Enquirer the couple really want a baby.

"Mariah and Nick are trying anything and everything to conceive," divulged an insider. "After almost a year of trying the natural way, they visited a fertility clinic to help make their baby dream come true. Mariah turns 39 this month, and she really wants to give birth before her 40th birthday. If they get pregnant soon, they won't make an announcement, even to close friends, until the three-month mark just to be on the safe side," says a friend. "Mariah has cut out fast food and junk food. She's also taking prenatal vitamins and nutritional supplements. The only thing she believes is lacking from her life is a little one, and Nick is up for the challenge."

We wish them much luck and success. But hope the don't get greedy like the Octo-Mon, implanting multiple embryos.

OK, lambs.
