Margaret Adenuga underwent three previous IVF procedures before finally having twins.
Her husband Noah Adenuga, 77, told CNN that the couple, who married in 1974, had long wanted to have a child.
Adenuga said they never gave up even after the failed attempts.
The retired stock auditor told CNN, “I am a dreamer, and I was confident that this particular dream would come true.”
The babies were delivered by cesarean at 37 weeks last Tuesday at the Lagos University Hospital (LUTH), but the hospital only released the information recently to give the first mother time to recover, the statement said. .
Dr. Adeyemi Okunowo, who gave birth to babies, told CNN that a team of specialists had been assembled at the hospital to monitor the pregnancy because of his age.
“As an elderly woman and mother for the first time, it was a high risk pregnancy and also because she was going to have twins but we were able to manage her pregnancy to term,” Okunowo told CNN.
Last year, a 73-year-old Indian woman was safely delivered to twin girls after conception by IVF and is said to be the oldest person to have given birth at that age.
Okunowo said that while older women are able to conceive through IVF, doctors must expose the medical risks associated with pregnancy at this age.
“There are age-related medical complications that accompany pregnancy at this age, such as the birth of the premature baby. She is lucky but many may succumb to other complications during or after having a baby,” said he told CNN.
