JOHANNESBURG, OCT. 1 -- A 48-year-old woman gave birth today to her daughter's test-tube triplets, becoming the world's first surrogate mother of her own grandchildren.

Pat Anthony and the triplets, two boys and a girl, were reported doing well after the early-morning deliveries by Caesarean section at Johannesburg's Park Lane Clinic.

The private clinic declined to disclose further details of the highly publicized case. The family sold exclusive rights to the story -- South Africa's first surrogate birth -- to London's The Mail on Sunday newspaper.

Anthony agreed to bear the children of her 25-year-old daughter, Karen Ferreira-Jorge, whose uterus was removed after complications from the birth of her first child, a son, three years ago.

Eggs from Ferreira-Jorge were fertilized with sperm from her husband, Alcino, in a laboratory process known as in vitro fertilization. Four eggs were implanted in Anthony's womb. Normally, only one embryo develops in the process, but in this case three of the fertilized ova began growing, resulting in triplets.

{The two boys weighed 5 pounds 1 ounce and 4 pounds 10 ounces, United Press International reported. The girl, delivered last, weighed 2 pounds 13 ounces. A hospital source said the girl was placed in an incubator.}

Ferreira-Jorge, an aerobics instructor, was present for the birth, the press association said.

Family members and medical staff refused to talk to local reporters. A British television crew filmed the birth, but local reporters and photographers were not allowed access.

South African law makes no provision for surrogate motherhood, and government officials have said the Ferreira-Jorges will have to adopt the triplets in order to make them legally theirs. {Justice Minister Kobie Coetsee told Parliament last month that until adoption, the babies would legally be Ferreira-Jorge's siblings, UPI reported.}

The Roman Catholic family lives in the town of Tzaneen, 230 miles northeast of Johannesburg. The Vatican has condemned the practice of surrogate parenting and in vitro fertilization. The Roman Catholic priest in Tzaneen reportedly said he was not sure if Vatican policy on surrogate pregnancies would allow him to baptize the babies.
