Woman Delivers Two Sets of Identical Twins on the Same Day

Tressa Montalvo has given birth to two sets of identical twins on the same day — Valentine’s Day — without the use of any sort of fertility treatment.

Tressa and her husband Michael already have a two-and-a-half-year old and are now the parents of five boys. They had hoped to have a girl and say they will have to determine if they will try again to get pregnant and give birth to the girl they hoped for this time.

From the story about the birth:

The quadruplets were conceived spontaneously, without the help of any fertility treatments or drugs – something that has a one in 70 million chance of happening, the hospital says. They were born at 31 weeks by Cesarean section to Tressa, who is 36, The Woman’s Hospital of Texas in Houston says.

The couple had been trying for one brother or sister to keep their little boy Memphis, now 2 years old, company.  At 10 weeks, they learned she was having twins. But when the couple went in for Tressa’s 12 week check-up, they learned she was carrying not two, but four babies.

“If I wasn’t already on the table lying down, I’m pretty sure I would have hit the floor,” Tressa told TODAY.

Manuel’s immediate reaction was jubilation.

“The first thing I said was ‘Home run!’ and then I started jumping up and down,” he said.

The Montalvo’s doctor says this delivery is a very rare event.

“The incidence of spontaneous quadruplets is somewhere of the order of 1 in 500,000,” said Dr. Brian Kirshon, a specialist in maternal and fetal medicine at Houston Perinatal Associates. “And then if you take two sets of identical twins in the quadruplet set, the incidence must be one in many, many millions. It’s an extremely rare occurance.”

Last year, an amazing video showing MRI images of twins that doctors say are “fighting” in the womb, was well received worldwide. The video, showing evidence of the humanity of babies before birth, came as researchers were trying to find out more about a rare blood disease that can complicate pregnancies called twin-to-twin transfusion syndrome.

The video from scientists at London’s Center for Fetal Care shows two babies essentially pushing each other.
