Unusual images of a baby holding firm, his mum’s contraceptive coil that failed to prevent her from getting pregnant with him.

The baby, a boy, was born at Hai Phong International Hospital in the city of Hai Phong in northern Vietnam.

According to obstetrician Tran Viet Phuong, the device came out when the baby was born and he was holding it firmly when he took the pictures. 

Dr Phuong told local media: “After delivery, I thought him holding the device was interesting, so I took a picture. I never thought it would receive so much attention.

The baby’s 34-year-old mother claims the coil was inserted two years ago. However, it did not perform its function because she later realised that she was pregnant.

Dr Phuong said the device may have shifted from its original position, thus, becoming ineffective.

The mother had previously had two other children, according to reports. Probably, she had no intention of giving birth again, but the baby decided to be born against all odds.

An IUD, also known as a coil or copper coil is a T-shaped plastic and copper device inserted into the womb, which releases copper to stop pregnancy.

The coil is supposed to stop sperm fertilising a woman’s eggs and can work by either releasing copper or hormones after being inserted into a woman’s uterus.

It can protect against pregnancy for five to 10 years. When inserted correctly, the device is more than 99 percent effective, the NHS claims.
