The guidelines from NICE also recommend the following:
IVF treatment for eligible women who have been unable to conceive after two years of regular intercourse - one year earlier than previously recommended
Women who have been having artificial insemination, which can include same-sex couples
Women aged 40-42 who have not conceived after two years of regular unprotected intercourse or 12 cycles of artificial insemination should be offered one full cycle of IVF, if they have never previously had IVF treatment
Where women are under 40, and have not conceived after two years of regular intercourse or 12 cycles of artificial insemination, three cycles of IVF should be offered
The health watchdog NICE says women between the ages of 40 and 42 should be offered IVF on the NHS in England and Wales if they are having fertility problems. Previously, NICE did not recommend IVF for women older than 39.
NICE says is has been able to change its guidance because of a number of key medical advances.
The guidance does not apply to Northern Ireland or Scotland.
