Dr. Karen Maples told reporters that the babies were born Monday at Kaiser Permanante and were "doing quite well."
The hospital says the mother, who asked not to be identified, gave birth to six boys and two girls weighing between 1.8 pounds and 3.4 pounds.
Dr. Harold Henry said that "they were all screaming and kicking around very vigorously."
The first live-born octuplets were born in Houston in 1998, and one baby died about a week later. The surviving siblings - girls Ebuka, Gorom, Chidi, Chima and Echerem, and their brothers Ikem and Jioke - celebrated their 10th birthday in December.
Their parents, Nkem Chukwu and Iyke Louis Udobi, said they are astonished and grateful that their children have grown up to be healthy and active kids who are now in the fourth grade.
Chukwu said the new parents have much to look forward to. "Just enjoy it. It's a blessing, truly a blessing," Chukwu said. "We'll keep praying for them."
