Are IVF Add-Ons Worth the Extra Money? What the Evidence Says
When you start IVF, clinics may offer a range of optional extras known as “add-ons.” These are treatments or procedures that claim to improve success rates — but they also come with extra costs. So, are IVF add-ons worth it? And how can you tell which ones are backed by real science?
What are IVF add-ons? Add-ons are not part of standard IVF cost. They’re optional and typically offered at an extra cost. Common examples include:
- ICSI (intracytoplasmic sperm injection)
- Embryo glue
- Time-lapse embryo imaging
- PGT-A (preimplantation genetic testing for aneuploidy)
- Endometrial scratch
- Assisted hatching
- Immunology testing
Costs can vary widely:
- ICSI: £1,000 – £1,500
- Embryo glue: £200 – £500
- PGT-A: £2,000 – £3,500
- Time-lapse monitoring: £500 – £1,000
Why are add-ons controversial? The Human Fertilisation and Embryology Authority (HFEA) in the UK rates add-ons using a traffic light system:
- Green: Good evidence it improves success
- Amber: Limited or conflicting evidence
- Red: No evidence of benefit
As of 2025, most IVF cost add-ons are rated amber or red — meaning the evidence is not strong. Many patients pay thousands for treatments that may offer no real benefit.
When might add-ons help? Some add-ons may be helpful in specific cases:
- ICSI is standard for male factor infertility
- PGT-A may benefit older women or those with recurrent miscarriage
- Endometrial scratch might be considered after failed transfers
But none are guaranteed to work, and they should never be pushed as routine.
What should you do before accepting add-ons?
- Ask why it’s being recommended
- Check if it’s included in the HFEA’s green list
- Request studies or clinic success data
- Get a second opinion if unsure
Real-life example: Alex and Priya were offered PGT-A and time-lapse imaging. After researching, they declined both — saving over £3,500. Their second IVF cycle succeeded without any add-ons.
IVF add-ons are big business, but evidence doesn’t always justify the expense. Don’t feel pressured. Make decisions based on your diagnosis, not clinic upselling.
