A woman who underwent fertility drug treatments gave birth to quintuplets, four girls and a boy, "crying and vigorous" and all weighing less than 2 pounds, doctors said Friday. The babies were born by Caesarean section to Terry Simunich, 26, within five minutes between 11:58 p.m. Wednesday and 12:03 a.m Thursday, said Dr. Robert Guthrie chief of pediatrics at Magee-Women's Hospital in Pittsburgh

"The infants have been stabilized and are in critical condition in Magee's Neonatal Intensive Care Unit," Guthrie said.

Guthrie said the babies were 13 weeks premature and "all crying and vigorous when born."

"I was awfully tired. I feel pretty good today. I'm glad to get it over with in one fell swoop," Mrs. Simunich, a nurse, told a news conference. "I don't want to do this again, but it was worth it."

"I'm five times happier," said her husband, Max, 28.

The children were named Bradley Andrew, Kathryn Elizabeth, Emily Marie, Allison Nicole and Rachel Lauren.

The boy was delivered first. Three of the babies weighed 1 pound, 10 ounces, one was 1 pound 8 ounces and another 1 pound, 9 ounces, Guthrie said.

Mrs. Simunich and her husband tried unsuccessfully for two years to achieve a pregnancy before she started receiving the fertility drug Pergonal, doctors said.

The husband, a grocery buyer for the Peter J. Schmitt Co. of Sharon, Pa., was in the delivery room for the births.

The couple said they would move out of the master bedroom in their four-bedroom home in Greenville, Pa., 60 miles north of Pittsburgh, and turn it into a nursery.
