A rare and medically significant birth has been reported in St. Petersburg, where a woman gave birth to four identical baby girls, the first such case officially recorded in Russia.The delivery, which took place at a maternity hospital in the city, has attracted attention because of its extreme rarity. Medical estimates suggest that monochorionic, or identical, quadruplets occur in approximately one in 15.5 million births. Globally, only 15 such cases have been recorded.All four babies were born in the 32nd week of pregnancy and their condition is said to be stable. His birth weight was between 1,360 g and 1,640 g, and his length was between 37 cm and 41 cm. Doctors have described these figures as strong for babies born at this stage.In a statement shared by the hospital on Russia’s social media platform VKontakte, the team said, “Four charming sisters were born at 32 weeks. According to estimates, monochorionic (identical) quadruplets occur once in 15.5 million births. Such unique births have not been reported in the country.”What makes matters especially complicated is that all four babies developed from the same fertilized egg and shared the same placenta, a condition known as a monochorionic pregnancy. In most multiple pregnancies, each baby has a separate placenta. Doctors say the risk is higher in such cases and constant monitoring is required.“For a pregnancy of 32 weeks, this is an excellent outcome, made possible due to proper management of the mother and expertise of the doctors in the antenatal department,” the hospital said.The delivery required the coordinated effort of a large medical team, including obstetricians, anesthesiologists, intensive care specialists, midwives, and neonatologists. Each baby was immediately attended to by neonatologists and specialized nurses to ensure proper care from the first moment after birth.According to the hospital, the process was led by the chief physician, Professor Anton Mikhailov, as well as a team of specialists from the antenatal department and the obstetric unit. The operation was described as highly complex, requiring complete precision and teamwork.Doctors explained that identical, or monozygotic, pregnancies occur when a single fertilized egg splits into multiple embryos, resulting in children with identical genetic makeup and the same sex. There is no known way to predict or prevent such events.The case is now seen as a milestone in Russian medical practice, highlighting both the rarity of the occurrence and the level of care required to successfully manage such a high-risk pregnancy.
