Texas woman gives birth to 2 sets of identical twins - | News for Yuma, Imperial Valley, El Centro, AZ & CA

HOUSTON (AP) -- A Texas woman has beaten long odds in delivering two sets of identical twin boys.

The Houston Chronicle reports Tressa Montalvo delivered her sons on Thursday - Valentine's Day - at The Woman's Hospital of Texas.

It says the odds of giving such a birth naturally are one in 70 million.

The 36-year-old Montalvo delivered sons Ace and Blaine at 8:51 a.m. Ace weighed 3 pounds, 10 ounces, and Blaine weighed in at 3 pounds, 15 ounces. Sons Cash and Dylan arrived a minute later - Cash at 2 pounds, 15 ounces, and Dylan at 3 pounds, 6 ounces.

Montalvo says she and her 43-year-old husband, Manuel, planned the pregnancy but didn't use fertility drugs. In her words, "I guess we just succeeded a little too much."
