HOUSTON (AP) -- A Texas woman has beaten long odds in delivering two sets of identical twin boys.
The Houston Chronicle (http://bit.ly/W0Asnn) reports Tressa Montalvo delivered her sons on 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.
Montalvo, 36, 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 said 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."
