London, Jan 16 (Reuters): Women’s problems with the opposite sex begin in the womb because boys — according to a new study — cause more complications than girls during labour and delivery.
Male infants require more caesarean section or instrument deliveries than girls, cause longer labours and need more foetal blood samples and hormone stimulation to induce contractions. Boy babies are larger and heavier and have bigger heads than girls but Maeve Eogan, of National Maternity Hospital in Dublin, Ireland, said that does not explain all the differences. “We don’t know what the answer is,” she said.
The sheer size difference between the sexes could account for longer labours and more caesarean sections but boy babies are also more likely to suffer from foetal distress which is not affected by size. “There is obviously some sort of inherent vulnerability of male infants,” she said.
