HOUSTON -- A Texas woman has beaten long odds in delivering two sets of identical twins.
The Houston Chronicle reports Tressa Montalvo delivered her sons on Thursday -- Valentine's Day.
The report says the odds of giving such a birth naturally are one in 70 million.
The 36-year-old Montalvo delivered the sets of sons within a minute of each other.
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."
