The chances of a pregnancy during IVF treatment is not affected by a woman's stress levels.
This is according to research conducted at Cardiff University.
Published in the British Medical Journal, the study reviewed 14 previous projects, looking at a total of 3,583 women.
The women were all assessed on their stress levels using recognised psychological techniques before they began the fertility treatment.
Afterwards, the results of the treatment were monitored. It was confirmed that women who were stressed before treatment were no more or less likely to become pregnant.
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."
