International health insurance customers could be glad to learn that emotional distress does not reduce the chances of falling pregnant through IVF.
Research conducted by a team at Cardiff University found that levels of stress have no impact on the likelihood of a woman falling pregnant or not.
The team looked at 14 previous studies, which assessed 3,582 women.
Each woman was assessed to determine how stressed they were at the beginning of their IVF treatment using recognised psychological techniques.
Professor Jack Boivin, lead researcher from Cardiff University, told the BBC: "There are a lot of myths around how people get pregnant.
"Women having fertility treatment who do not get pregnant early on often blame themselves for getting too stressed out and the longer they remain not pregnant the more stressed they get. This just reinforces the myth."
IVF treatments can be very expensive, making overseas health insurance a must.
