Emotional distress does not affect the success of IVF or other assisted reproductive techniques, according to a study. The report, published in the British Medical Journal aims to dispel the myth that stress prevents women from becoming pregnant.

Researchers from Cardiff University reviewed 14 previous studies involving 3,583 women.

Patient charity Infertility Network said the report was encouraging.

The report reviewed previous research studies into the efficacy of assisted reproduction therapy.

In the 14 studies examined, women had had their stress levels assessed before beginning treatment and then underwent a single cycle of assisted reproductive therapy.
