IVF Add-Ons Explained: What the Evidence Says About ERA, Scratching, PRP and More
Many IVF clinics offer optional extras such as ERA testing, endometrial scratching, PRP and assisted hatching. Here is what each one is, what the evidence suggests, when a doctor may consider it, and what to ask before you pay.
During an IVF consultation, you may be offered optional extras on top of standard treatment, each described as a way to improve your chances. This guide explains what IVF add-ons are, what the evidence suggests about the common ones, when a doctor may consider them, and what to ask before you agree or pay.
The Short Answer
What to Know IVF add-ons are optional extras offered on top of standard IVF, and for most of them the evidence of benefit for the average patient is limited or unclear. A few may help in specific situations. Your doctor should be able to explain why one is advised for you, what evidence supports it and what it costs. Be cautious of add-ons presented as routine, or as a way to guarantee success.
मराठीत थोडक्यात: IVF अॅड-ऑन्स हे मानक IVF व्यतिरिक्त ऐच्छिक अतिरिक्त उपचार किंवा चाचण्या असतात, आणि त्यापैकी बहुतेकांचा सरासरी रुग्णाला होणारा फायदा मर्यादित किंवा अस्पष्ट असल्याचे पुरावे सांगतात. काही निवडक परिस्थितींमध्ये ते उपयुक्त ठरू शकतात, आणि ते तुम्हाला का सुचवले आहे, कोणता पुरावा आहे आणि खर्च किती आहे हे डॉक्टरांनी समजावून सांगावे. अॅड-ऑन्स नेहमीचे म्हणून किंवा यशाची हमी देणारे म्हणून सादर केले जात असतील, तर सावध राहा.

What Are IVF Add-Ons?
IVF add-ons are extra tests, procedures or medicines that are not part of a standard IVF cycle. They are usually optional, usually cost extra, and are usually offered with the hope of improving the chance of implantation or pregnancy.
Some add-ons have a clear reason to be used in specific patients. Many others have been studied and have not shown a clear benefit for most people. It is useful to know the difference before you decide.
Why Are They Offered?
IVF is emotionally and financially demanding, and wanting to do everything possible is natural. Add-ons are offered because early or small studies sometimes look promising, because some do help in particular situations, and because clinics compete. Not every add-on that is offered has been tested well in large trials.
How to Judge an Add-On
- Is there good evidence? — Look for results from well-designed trials, not only small studies or personal stories.
- Who benefited? — Benefit seen in one group, such as older women, may not apply to you.
- Are there any harms? — Some add-ons carry risks, discomfort or delay.
- What does it cost? — Several add-ons together can add up.
- Is there a simpler alternative? — Sometimes better timing or a different protocol does the same job.
Common Add-Ons and What the Evidence Suggests
This table gives a general summary. Evidence changes over time, and your doctor can tell you what applies to you.
| Add-on | What it is | What the evidence suggests | When it may be considered |
|---|---|---|---|
| Endometrial scratching | A small injury to the uterine lining before transfer, intended to help implantation | Larger trials have not shown a clear benefit for most patients | Rarely, after careful discussion |
| ERA (endometrial receptivity) test | A lining sample tested to find the timing most suited for transfer | Trials have not shown a clear benefit for patients in general | Sometimes discussed after repeated failed transfers |
| Embryo glue | A transfer medium meant to help the embryo attach | Evidence is mixed. See embryo glue in IVF | Selected cases after discussion |
| Assisted hatching | Thinning or opening the embryo's outer shell with a laser | Evidence is mixed | Selected cases, such as a thicker shell, frozen embryos or previous failures |
| Time-lapse imaging | Incubators with cameras that watch embryos continuously | It has not clearly improved live birth rates | Helps embryologists observe embryos, and adds cost |
| Embryo chromosome screening (PGT-A) | Testing embryos for chromosome numbers. See genetic testing (PGT) | Benefit is debated for patients in general | Selected cases, such as older age or repeated loss |
| PRP (platelet-rich plasma) in the uterus or ovary | A product made from your own blood | Evidence is preliminary, and much of it is still research | Usually within research settings |
| Immune treatments | Medicines such as steroids or infusions meant to calm the immune system | Evidence is limited. See natural killer cells and IVF | Only when a specific condition has been diagnosed |
| Growth hormone, DHEA or CoQ10 | Medicines or supplements meant to help egg response | Evidence is mixed | Selected poor responders under specialist advice. See how to improve egg quality |
| Special sperm selection (IMSI, PICSI) | Ways of choosing sperm under higher magnification or by binding | Evidence is limited | Selected male-factor cases |
Treatments for a Diagnosed Problem Are Different
Not everything offered beyond a standard cycle is an optional extra. Some treatments address a specific problem that has been found, and they are part of medical care, not add-ons:
- Treating a polyp, adhesions or a septum — See hysteroscopy before IVF.
- Treating a swollen blocked tube before transfer — See blocked fallopian tubes and hydrosalpinx.
- Treating thyroid disease — See thyroid and fertility.
- Blood-thinning treatment for a diagnosed clotting condition — See antiphospholipid syndrome and recurrent miscarriage.
- ICSI when sperm quality calls for it — See ICSI vs standard IVF.
Questions to Ask Before Agreeing
- Why do you recommend this for me in particular?
- What is the evidence that it helps patients like me?
- Are there any risks or downsides?
- What does it cost, and is it included in the package?
- What happens if I decline? Will my treatment change?
- Is it being offered to everyone, or only to people in my situation?
Red Flags to Watch For
- Add-ons bundled into every package by default — Without a reason linked to your tests or history.
- Claims that an add-on guarantees or greatly raises success — No add-on can promise this.
- Pressure to decide quickly — A decision about extra treatment should not be rushed.
- No explanation of the evidence — A good doctor can describe what is known and what is uncertain.
- Several add-ons recommended together after a failed cycle — Without a clear reason for each.

What About Cost?
Each add-on adds to the final bill, and several together can add up considerably. Ask for an itemised estimate that shows which items are optional, and check what is already included in your package. See IVF treatment cost in India.
Common Myths About IVF Add-Ons
- Myth: "More add-ons mean higher chances." — Many add-ons have not shown a clear benefit for most people, and adding several does not multiply the benefit.
- Myth: "If a clinic offers it, it must be proven." — Some add-ons are offered before good evidence exists.
- Myth: "Add-ons are harmless." — Some carry risks, discomfort or delay, and all cost money.
- Myth: "All add-ons are a waste." — A few may help in specific situations, so each one deserves a fair look.
- Myth: "After a failed cycle, you should try every add-on." — A failed cycle calls for a careful review, not a long list of extras. See IVF failed twice or three times.
When to See a Doctor
If you are offered an add-on and are not sure it is right for you, ask your fertility specialist to explain the reason, the evidence and the cost. If cycles have not worked, ask for a careful review of your plan, and consider a second opinion. A clear conversation about what is likely to help is more useful than a long list of extras.
