- Applies to women whose mothers suffered from fetopelvic disproportion
- This causes a woman’s pelvis to be too narrow, or a baby too big, for natural birth
- Women born due to the condition are 2.8 times more likely to have it themselves
- C-sections may prevent natural selection from weeding out the disorder’s genes
- As a result, Caesarean births have increased by up to 20% in recent decades
Women born by Caesarean are more than twice as likely to have a c-section themselves if they have children, new research reveals.
Females who are born via c-section due to their mothers having a condition known as fetopelvic disproportion are 2.8 times more likely to also suffer from the disorder, a study found. Fetopelvic disproportion prevents babies fitting through their mothers’ pelvises.
Researchers believe c-sections hinder natural selection from removing the genes responsible for the condition.
As a result, Caesarean births have increased by up to 20 percent in recent decades, the research adds. Risks of having a c-section include infection, excessive blood loss and clots.
Lead author Dr Philipp Mitteroecker from the University of Vienna, said: ‘Indeed we found studies reporting risks for Caesarean up to twice as high for women born by Caesarean as compared to women born vaginally.’

‘WE HAVE REMOVED NATURAL SELECTION’: CANCER TREATMENT ALLOWS TUMOUR-CAUSING GENES TO BE PASSED ON
Cancer treatment is a ‘double-edged sword’ by allowing survivors to pass on their tumour-causing genes, a leading scientist claimed earlier this month.
Study author Professor Maciej Henneberg from the University of Adelaide, said: ‘Besides the obvious benefits that modern medicine gives, it also brings with it an unexpected side-effect – allowing genetic material to be passed from one generation to the next that predisposes people to have poor health.
‘Because of the quality of our healthcare in western society, we have almost removed natural selection as the “janitor of the gene pool”.
‘The accumulation of genetic mutations over time and across multiple generations is like a delayed-death sentence.’
Countries with the most advanced healthcare systems have up to 14 times higher cancer rates as they are less vulnerable to the effects of natural selection, new research suggests.
C-sections up by 20% in recent decades
The researchers found women born by Caesarean due to fetopelvic disproportion are 2.8 times more likely to have c-sections themselves if they have children.
Fetopelvic disproportion is the inability of a baby to be born vaginally either due to a woman’s small pelvis or an infant’s large body.
The researchers believe c-sections are hindering natural selection from removing the genes responsible for fetopelvic disproportion.
As a result, Caesarean births have increased by up to 20 per cent in recent decades.
Dr Mitteroecker said: ‘Indeed we found studies reporting risks for Caesarean up to twice as high for women born by Caesarean as compared to women born vaginally.’
The risks of having a c-section include infection, excessive blood loss, and clots in the lungs or legs.
Anesthesia given during Caesarean sections can also cause nausea, vomiting and headache.
The findings were published in the journal PNAS.
