Most IVF “add-on” treatments sold to people hoping to boost their chances of having children are not backed by reliable evidence, fail to boost fertility and may be a complete waste of money, the largest study of its kind has concluded.
There has been a surge in extra procedures, medicines or techniques offered to patients in addition to standard IVF with bold claims they will increase the probability of success. Take-up is widespread, with more than 70% of IVF patients in the UK, Australia and New Zealand paying for one or more add-on during IVF treatment.
But the world’s most comprehensive review into their effectiveness – and the evidence behind them – found the majority show no effect on fertility or remain inconclusive due to limited or low-quality data.
Unproven add-ons also lead to false hope, greater financial strain and needless medical procedures at what is already a difficult time for patients, experts behind the research said. The findings were published in The Lancet Obstetrics, Gynaecology & Women’s Health journal.
“In many countries, infertility care is largely provided by private clinics where IVF is highly commercialised, and some add-ons are extremely expensive,” said Dr Sarah Lensen of the University of Melbourne.
“Our review finds a lack of evidence that most of the IVF add-ons we assessed provide any benefit to patients. Unproven add-ons can lead to false hope, greater financial strain and unnecessary medical procedures at what already can be a very difficult time for patients.”
