Guanajuato, Mexico - A woman has given birth to septuplets in Mexico but, sadly, one of the infants has died.

The Guanajuato Health Secretariat reported the Caesarean-section births of four girls and three boys to Maria del Rosario Hernandez Tovar, a 30-year-old who had undergone fertility treatment.

The Celaya Maternity Hospital director, Jose Luis Hernandez, said that "we attended the birth of six babies by the woman, the problem is that it was too soon," a reference to the gestation period of just 25 and a half weeks.

"She underwent a Caesarean and had seven babies. Unfortunately, one of the baby girls weighed too little - the minimum weight that would have given hopes she would live is from 500 to 550 grams (1 lb, 2 oz. to 1 lb. 3 oz.) That girl weighed 450 grams (1 pound)," the doctor said, as cited in local media.

State Health Secretary Francisco Ignacio Ortiz Aldana said that everything humanly possible is being done to care for the three girls and three boys who survived, and who weigh between 550 and 650 grams.

Hospital officials said the mother is in weak but stable condition.
