A third of depressed new fathers have thought about hurting themselves or their child, a worrying new study shows.
Experts say post-natal depression in men goes undetected and untreated and they are reluctant to seek help, the Daily Mail reports.
Some 83 per cent of depressed males have kept quiet about their suffering in the months after having a child.
Swedish scientists warned current methods to screen men for depression are not effective, hence why PND in males may be more common than previously thought.
The team at Lund University said as a result, many fathers won't get the help they need - even if they knew how to ask for it.
Effect on children
If depression in new parents is not detected their children suffer too, since depressed parents are less sensitive to the needs of their child, particularly infants with a tendency to cry frequently.
Babies of depressed parents receive less stimulation, which becomes a contributing factor to slower development.
In some cases, depression can lead to neglect or inappropriate force being used on the child.
This behaviour is not unusual, said Dr Elia Psouni, associate professor of developmental psychology at the university.
"Depression does not just involve major suffering for the parent, it's also a risk for the child," she said.
Fathers are not routinely screened
New mothers are routinely screened for depression and an estimated 10-12 per cent are found to be affected in their first year after giving birth. But fathers are not routinely screened.
The study of 447 new dads showed that the established method of detecting depression - the Edinburgh Postnatal Depression Scale (EPDS) - works poorly on men.
The screening method does not capture symptoms common in men, such as irritation, restlessness, low stress tolerance and lack of self-control.
"As a result current statistics may not tell the whole truth about depression in new fathers," said Dr Psouni.
A third of the depressed fathers in the study had thoughts of hurting themselves but few were in contact with the healthcare system.
Among those classified as "moderately to severely depressed", 83 per cent had not shared their suffering with anyone. The corresponding figure for new mothers is estimated at between 20 and 50 per cent.
Telling people you feel depressed is a taboo for every new parent, as you are expected to be happy, say the researchers.
Previous research has indicated that men are reluctant to seek help for mental health issues, especially depression, according to the report.
"It's doubtful that they would reveal their suffering to a paediatric nurse," said Dr Psouni.
The screening of depression in fathers should take in longer than the 12 months currently applied in studies of new mothers.
"Among dads, depression is common even at the end of the first year, which may be due to the fact that they rarely get help," she added.
