What Is Embryo Glue? Understanding Hyaluronan-Enriched Transfer Medium

Key Takeaways

• Embryo glue is a transfer medium enriched with hyaluronan. It is not an adhesive.
• Research suggests a possible improvement in live birth outcomes, but it cannot guarantee implantation.
• It does not correct chromosome problems in an embryo or treat conditions inside the uterus.
• Your doctor and embryology team will decide whether it is suitable and explain any additional charge.

If you have heard about embryo glue IVF before your transfer, you may wonder whether it helps an embryo stick inside the womb. The name makes that sound quite literal. But this is a specially prepared laboratory fluid, not something that glues an embryo into place.

At Pravi Global IVF in Lajpat Nagar, we encourage you to ask what any proposed addition actually does. Before agreeing, you should understand the evidence, limitations and cost without feeling pressured.

What Is Embryo Glue?

EmbryoGlue is a commercial name for a hyaluronan-enriched embryo transfer medium. People also use “embryo glue” loosely for similar media. The embryo is placed in this fluid before being transferred into the uterus through a thin catheter.

Hyaluronan, also called hyaluronic acid, is a substance naturally present in the body, including reproductive tissues and fluids. It holds water and contributes to the environment around cells.

Transfer media provide a controlled environment while the embryo is outside the incubator and during transfer. Hyaluronan enrichment changes the fluid’s properties, including its viscosity, and may support interactions involved in implantation.

Some standard transfer media already contain hyaluronan at lower concentrations. So the useful question is not simply “glue or no glue?” Ask what medium your laboratory normally uses and what would change.

How Does Embryo Glue IVF Work?

Once the embryology team has selected an embryo for transfer, they prepare it in the chosen medium according to laboratory protocols. The embryo and a small amount of fluid are loaded into a soft transfer catheter.

The doctor passes the catheter through the cervix and releases its contents inside the uterus, usually with ultrasound guidance. The enriched medium is part of this transfer process, not a separate procedure.

• There is usually no additional injection or incision for using this medium.
• It does not physically attach the embryo to the uterine lining.
• Implantation still depends on the embryo, the lining and other biological factors.
• The laboratory follows product-specific instructions for handling and exposure.

You would not normally feel a difference because a different transfer medium was used. Any discomfort is more likely related to the speculum, catheter or bladder fullness during transfer.

What Does the Research Say?

Systematic reviews of randomised trials suggest that transfer media containing higher concentrations of hyaluronan probably improve live birth outcomes compared with media containing little or none. That is encouraging, but it needs careful interpretation.

Studies differ in their patients, transfer practices and laboratory methods. Some included transfers of more than one embryo. Results therefore do not tell us exactly how much benefit one particular couple will receive.

Reviews have also found an increase in multiple pregnancy with higher-hyaluronan media. When more than one embryo is transferred, improved implantation can mean twins or more. Discussing single-embryo transfer remains important.

A possible benefit is not a promise. Evidence does not establish that every patient needs this addition, or that it reliably solves repeated unsuccessful transfers. Your doctor should explain how the research applies to your treatment.

What It Can and Cannot Do

When discussing embryo glue IVF, separating the proposed role from the marketing name helps you make a calmer decision.

Who Might Discuss This Option?

The medium may be considered for fresh or frozen embryo transfers, depending on the laboratory protocol and clinical situation. Some clinics use it routinely; others offer it as an optional addition.

After an unsuccessful transfer, it is understandable to want something different. Still, adding a product should not replace a review of embryo development, the uterine cavity, transfer technique and medication timing.

• Ask whether there is evidence relevant to your type of transfer.
• Check whether the laboratory already uses a hyaluronan-containing medium.
• Discuss how many embryos will be transferred and why.
• Ask what other findings need attention before proceeding.

For example, if a scan suggests a polyp inside the uterine cavity, the doctor may recommend further assessment. Changing the transfer medium would not address that finding.

Safety, Charges and Questions Before Consent

Available research has not established a clear increase in other adverse outcomes, but safety reporting has limitations. Your team should discuss the product’s ingredients, relevant allergy history and any uncertainty rather than describe it as risk-free.

Ask whether embryo glue IVF is included in your package or billed separately. Get this clarified before transfer day, when decisions can feel more emotional.

• What product will you use, and why are you recommending it for me?
• What benefit is realistic given my treatment history?
• What is the additional charge, if any?
• What would the plan be if I decline it?

You should not be made to feel that declining an optional addition means you are not doing enough. A genuine discussion leaves room for questions and informed choice.

Frequently Asked Questions

Is embryo glue an actual glue?

No. It is a fluid enriched with hyaluronan, used around the embryo during transfer. It does not seal the embryo to the lining or prevent it from “falling out”.

Does embryo glue IVF guarantee pregnancy?

No. Research suggests a possible benefit, but pregnancy and live birth depend on several factors. Your doctor will decide whether recommending it is reasonable for your circumstances.

Can it be used with a frozen embryo?

Yes, it may be used during frozen embryo transfer if suitable under the laboratory’s protocol. It does not replace correct preparation of the uterine lining or prescribed hormone support.

Will I need bed rest after the transfer?

Routine prolonged bed rest is not recommended after embryo transfer. Follow your clinic’s activity advice and continue your medicines. Normal gentle movement does not make an embryo fall out.

Is it necessary after one failed transfer?

Not automatically. One unsuccessful transfer does not identify a specific implantation problem. Your doctor should review your treatment before suggesting this or any other addition.
