After struggling through three years of fertility treatments, Jeffery and Sheryl McGowen were blessed with identical twins. Twice.

Sheryl McGowen gave birth to two sets of identical twins via Caesarean section at the Women’s Hospital of Texas in Houston on Monday.

The first twins born are named Jacob and Jacoby, and the second two were named Justin and Jason. The four brothers, who were about 10 weeks early, weigh between 3 pounds, 4 ounces and 2 pounds, 5 ounces.

“I’m still waking up every morning and touching those little wristbands just to check if it’s still real,” said Jeffery McGowen, a deputy with the Harris County Sheriff’s Office.

All four were still on ventilators on Wednesday, but were otherwise healthy and expected to come off the breathing machines on Friday, their father said. Their mother, 35, is doing well, he said.

The odds of two pairs of identical being born during the same pregnancy are about one out of 11 million, the McGowens’ doctors told them.
