It is important to keep in mind that for most patients, having routine cycles of proven fertility treatment are effective without using any treatment add-ons. If you are paying for your own treatment, you may want to think about whether it might be better to pay for multiple cycles of IVF or IUI, rather than spending large sums of money on a single treatment cycle with treatment add-ons that haven’t been proven to be effective.
Treatment add-ons with limited evidence
For some treatment add-ons there is not enough evidence to show that they are effective at improving treatment outcomes. This page explains what some of these treatment add-ons are.
Complementary and alternative therapies may be suggested to patients undergoing fertility treatment to help with relaxation or general wellbeing. We do not regulate any complementary therapies and they are not usually offered in an HFEA licensed fertility clinic.
If a treatment add-on is offered, you should question why it is being offered and ask if it may be of benefit for you specifically. Questions about treatment to ask your fertility clinic can be found here.
While we do our best to identify potential safety concerns, some of the studies that we use to decide the ratings may have been designed to report on the effectiveness of a treatment add-on and not to report on safety or risk factors.
