Erin Andrews is contemplating another drive toward the end zone.

Fifteen months after the sportscaster and husband Jarret Stoll welcomed son Mack with the help of a surrogate, "We're talking about trying it again," she revealed in an exclusive interview with E! News. "And I was really, really honest with my doctor a couple weeks ago. I just said, 'We've had so much high with the birth of Mack and how great he's doing that I don't want to go back to that place of failure again, and I'm really, really afraid of it.'"

While she's more familiar with the playbook at this point, having come out the other side of her traumatic 10-year fertility journey, she's anxious about tackling the process again.

"It's crazy, because once you get back on the phone with your fertility doctor and you start talking about the journey again, PTSD all comes back of how crappy you felt, how numb your body gets, just the fear of loss," the 46-year-old recounted of losing two embroyos before learning their surrogate was pregnant with their son. "So, it's a lot. It's a loaded thing."
