Two women in the study were so afraid of giving birth that they had abortions, 10 women had their babies and then asked to be sterilised, five had suffered sexual abuse leading to tokophobia and 11 opted for Caesarean sections.
Professor Ian Brockington believes tokophobia is a largely unrecognised condition.
Any woman needing information about tokophobia should contact the mother and baby unit at Queen Elizabeth Psychiatric Hospital on 678 2195.
The National Phobics Society receives up to 10 calls a week from women suffering from Tokophobia - an unreasonable fear of giving birth.
Dr Kristina Hofberg, a consultant psychiatrist for South Staffordshire Mental Health NHS Trust and the UK's leading expert on Tokophobia, says this is just the tip of the iceberg.
