IVF Add-Ons: Which Extras Are Backed by Evidence?
Reading time: about 7 minutes. This article is educational and does not replace an individual consultation.
When you start IVF, you may be offered a range of extra procedures — “add-ons” — promising to improve your chances. Some are genuinely useful in specific situations; many are not well supported by evidence for most patients. This article helps you ask the right questions, so your treatment is guided by evidence rather than hope or marketing.
In short: IVF add-ons are extra tests, procedures or supplements offered in addition to standard IVF. For most of them, good evidence that they improve the chance of a baby is lacking: none of the 42 recommendations in ESHRE’s 2023 review could be based on high-quality evidence. Some extras suit specific situations, so ask what the evidence shows for you.
Who this article is for
This is for couples in Ahmedabad and Gujarat undergoing or considering IVF who want to make informed decisions about optional extras.
What IVF add-ons are
Add-ons are optional treatments offered alongside standard IVF, often at extra cost, with the suggestion that they improve success. The honest position is that for many add-ons, the evidence that they increase the chance of a baby for most patients is limited or absent — and a responsible clinic is transparent about this rather than recommending them routinely [Source: ESHRE Good Practice guidance; HFEA information on treatment add-ons].
The principle: evidence first
The key question for any add-on is simple: is there good evidence that it improves the chance of a healthy baby for someone in my situation? If the answer is no, the add-on is generally not worth the extra cost or intervention. Some add-ons are appropriate for specific, defined situations — the issue is applying them to everyone [Source: ESHRE Good Practice guidance].
How to think about common add-ons
Rather than labelling individual products, it helps to use a traffic-light way of thinking, which regulators have popularised:
- Established and appropriate in specific cases — for example, ICSI where there is a male-factor indication, or genetic testing in defined situations.
- Uncertain — evidence not yet convincing — many add-ons sit here; they may be reasonable in a trial or specific context but not as routine.
- Not supported for routine use — where evidence does not show benefit for most patients.
Where an add-on sits can change as research evolves, which is why an up-to-date, honest discussion matters [Source: HFEA add-ons information].
What does the latest evidence say about common add-ons?
For the add-ons patients ask about most, the evidence is either against routine use or still uncertain. ESHRE’s 2023 recommendations and Cochrane’s 2026 updates point in the same direction.
| Add-on | What current evidence says | Source | Strength of evidence |
|---|---|---|---|
| Immune blood tests; uterine NK-cell testing | Not recommended | ESHRE good practice recommendations, 2023 | Guideline recommendation |
| Immune treatments such as intralipid or IVIG | Not recommended | ESHRE good practice recommendations, 2023 | Guideline recommendation |
| Endometrial receptivity tests | The currently available tests are not recommended | ESHRE good practice recommendations, 2023 | Guideline recommendation |
| Endometrial scratching | Unclear whether it improves the chance of a live birth; it usually causes mild-to-moderate pain | Cochrane review, updated May 2026 | Uncertain (moderate-certainty evidence of an unclear effect) |
| Antioxidant supplements (for women) | Mixed, low-quality evidence: a 2026 review suggests a possible benefit, while Cochrane rates the evidence low to very low and has flagged retracted studies | Cochrane review 2020 (editorial note, March 2026); meta-analysis 2026 | Uncertain |
| Embryo culture media | No medium has been shown to be better than the others | Cochrane review, August 2026 | Uncertain |
What this means for you: an add-on that is not supported for your situation is not a missing piece of your treatment, and declining it should not lower your chance of success. Tell your team about every supplement or remedy you take, including “natural” products, so they can check what is relevant and safe for you.

Questions that protect you
- Is this add-on recommended for my specific situation, or offered to everyone?
- What does the best evidence say about whether it improves my chance of a baby?
- What does it cost, and what happens if I decline it?
- Is it being offered as part of a properly conducted study?
Ethical IVF in Ahmedabad
Ethical fertility care recommends only what is likely to help you and is transparent about evidence. Balaji Horizon Women’s Hospital, on Science City Road in Ahmedabad, takes an evidence-based approach to IVF — using add-ons only where they are genuinely indicated, and explaining the reasoning, rather than adding cost without benefit.
When to seek advice
If you are offered IVF add-ons, ask for the evidence relevant to your situation before agreeing. It is always reasonable to decline an extra that is not supported for someone like you [Source: ESHRE Good Practice guidance].

Frequently asked questions
Are IVF add-ons worth the money?
For many add-ons, the evidence that they improve the chance of a baby for most patients is limited, so they may not be worth the extra cost. Some are appropriate in specific situations. The right test is whether good evidence supports it for you [Source: ESHRE Good Practice guidance].
Why are add-ons offered if the evidence is weak?
Add-ons are sometimes offered out of a genuine wish to help, and occasionally driven by demand or commercial factors. Regulators encourage transparency about evidence so patients can make informed choices [Source: HFEA add-ons information].
Which add-ons are actually established?
Some interventions are well established for specific indications — for example ICSI for male-factor infertility, or genetic testing in defined situations. The concern is applying add-ons routinely to everyone rather than where indicated [Source: ESHRE Good Practice guidance].
Will declining add-ons reduce my chances?
Declining an add-on that is not supported for your situation should not reduce your chance of success, since standard IVF is the evidence-based core of treatment. Ask specifically about evidence for your case.
How do I know what is right for me?
Ask whether each add-on is recommended for your specific situation, what the best evidence says, and what it costs. An honest clinic will give you this information and respect your decision.
