Jenitar Sau Na'amoana, 34, delivered four identical girls conceived naturally and born at 28 weeks and four days at Royal Brisbane and Women's Hospital on July 14. Doctors say the spontaneously conceived identical quadruplets are extraordinarily rare — roughly 1 in 15 million — while natural quadruplets generally occur about 1 in 700,000. The babies, Emily, Harriet, Catherine and Alexa, are stable in the NICU and the mother is recovering well after a cesarean delivery.
Australian Mother Delivers Naturally Conceived Identical Quadruplet Girls — A One-in-Millions Birth

Jenitar Sau Na'amoana, 34, has given birth to four identical baby girls in a case doctors are calling extraordinarily rare. The infants were delivered by cesarean at the Royal Brisbane and Women's Hospital in Queensland on July 14 and were born at 28 weeks and four days' gestation.
Rare Natural Conception
The quadruplets were conceived naturally from a single fertilized egg that split into four embryos — a phenomenon experts estimate occurs around 1 in 15 million for spontaneously conceived identical quadruplets. By comparison, the overall chance of conceiving quadruplets without fertility treatment is roughly 1 in 700,000, and most quadruplet pregnancies are associated with assisted reproductive technology.
Medical Care and Delivery
Na'amoana was followed by a multidisciplinary medical team from 10 weeks of pregnancy and was admitted to the hospital at 25 weeks for close monitoring. Because the fetuses shared a single placenta, the pregnancy carried heightened risks for complications such as preterm birth and other issues commonly associated with multiple gestation pregnancies.

“We are very excited to be able to care for this amazing little family, a big family now,” said Dr. Alexa Bendall, a maternal fetal medicine specialist who led the mother's care. “The fact that we've got four beautiful, healthy babies born at 28 weeks and four days is incredible.”
The delivery was by cesarean section on July 14. Hospital staff reported that Na'amoana lost a small amount of blood but did not experience excessive bleeding given the circumstances, and she is recovering well.
Newborns and Names
All four girls are stable and receiving care in the neonatal intensive care unit. Their names are Emily, Harriet, Catherine and Alexa — the latter chosen as a tribute to Dr. Bendall. The doctor described the gesture as a "beautiful tribute" and said she felt privileged to have supported the family.
Significance
Beyond the emotional and human interest elements, the case is medically noteworthy. Identical quadruplet pregnancies are exceptionally uncommon, and clinicians said they believe a spontaneously conceived set like this may be unprecedented in Australia. Specialists will continue to monitor the babies and their mother as they progress in the neonatal unit.
