A hospital in Brisbane, Australia, has recorded what it describes as an unprecedented obstetric event: the birth of four identical girls conceived spontaneously from a single fertilised egg and sharing one placenta. Emily, Harriet, Alexa and Catherine were delivered by caesarean section on 14 July 2026 at the Royal Brisbane and Women's Hospital at 28 weeks and four days of gestation. Their mother, Jenitar Sau Na'amoana, 34, had not planned the pregnancy and already has four children aged between one and ten, according to a hospital statement cited by Clarín.

Dr Alexa Bendall, a specialist in maternal-fetal medicine and obstetrics at the hospital, said the case had no comparison with any previous record. "We never saw a pregnancy conceived spontaneously of this type with quadruplets, and she somehow avoided all the complications and risks, both for herself and for her babies," Dr Bendall said. She added that the shared placenta was "unheard of" and that the pregnancy reaching a favourable outcome was extraordinary given the additional risks. The medical team had set a target of reaching 28 weeks. "We always said that if we could get to 28 weeks, we would be fine, so we are happy that she was able to reach that gestation," Dr Bendall said.

The probability of such a birth is one in 15 million pregnancies, according to the hospital. The pregnancy was natural, without any fertility treatment. Jenitar was followed by a large team of specialists from week ten and was hospitalised from week 25 for continuous monitoring due to the high risk. Dr Bendall noted that Jenitar "took everything calmly from the first day." The four babies remain in the neonatal intensive care unit and are progressing favourably, the hospital said.

An Israeli newspaper, Haaretz, noted that the babies were born at a stage where without modern medicine they would have no chance of survival, and that such early births are often associated with physical and cognitive developmental problems, a weak immune system, and behavioural disorders. The hospital has not released a long-term prognosis in its public statements. Jenitar and her husband Jortham are alternating care for their four older children with visits to the newborns, according to the hospital.
