The Paris public hospital network says the two boys and a girl weighed between 4 pounds 9 ounces and 5 pounds 5 ounces and measured between 18.1-18.5 inches.
An official at the Paris hospital network said Monday that the woman gave birth this weekend by Caesarean section. The official was not authorized to be publicly named.
The woman's pregnancy prompted controversy in France. French law concerning egg donation excludes women over 42 from access to the procedure.
No other information was immediately available about the newborns or the mother.
