Three in four women starting fertility treatment will have a baby within five years, according to a new study.
Led by Copenhagen University Hospital, the large cohort study analysed the birth records of almost 20,000 women undergoing fertility treatment in Denmark between 2007 and 2010, as Denmark is one of only a few countries with full registry records linking all fertility treatments with live births.
After two years, 57 per cent of women had had a baby, 46 per cent of whom conceived by IVF when this was the first fertility treatment, while 34 per cent delivered after first-line intrauterine insemination (IUI).
Total birth rates increased cumulatively over the five-year study period, from 65 per cent after three years to 71 per cent after five years. However, these rates did not increase following IUI when treatment was extended beyond two years, when most patients had switched to IVF.
At five years, total birth rates were 80 per cent for women under 35 years, 60.5 per cent for those aged 35 to 40 and 26 per cent for those aged 40 and over.
Dr Sara Malchau of Copenhagen University Hospital said: "Couples will often need several treatment cycles. And even though the greatest chance of conception is following treatment, there is still a reasonable chance of spontaneous conception."
