Embryo glue is a special culture medium used in IVF embryo transfer. It helps embryos implant, improving pregnancy rates in IVF-ET cycles. Despite its name, it is not real glue and does not “stick” the embryo to the uterine wall. Instead, embryo glue is the common name for a hyaluronan-enriched transfer medium. Hyaluronan, or hyaluronic acid, is a macromolecule that promotes implantation.
For IVF to be successful, the embryo must implant itself in the lining of the uterus. This step, known as implantation, is a delicate moment in the procedure that determines whether the pregnancy goes forward.
Embryo glue works by replicating the natural fluids in the womb. Simply put, it is a nutrient-dense, protein-rich solution that mimics the natural fluid environment of the uterus during implantation. It also thickens the medium, keeping the embryo from shifting after transfer.
The process is simple and doesn't take much time out of your day. In the lab, the embryologist puts the selected embryo into the hyaluronan-enriched liquid. Embryos are generally left in the medium for 30 to 40 minutes before being placed in the uterus with a catheter. This procedural step is like a routine pelvic check, and most women don’t need anaesthesia. You can use embryo glue with both fresh and frozen embryos.
Embryo glue is not for everyone. But in some cases your doctor may advise you to use it. Some couples may choose to discuss it if they have:
Remember, although embryo glue can improve the odds of implantation, it is no substitute for high-quality embryos, a healthy endometrial lining, and excellent care.

Hyaluronan is a natural substadies of embryo glue have not shown a clear rise in miscarriage or birth defects. Large reviews hnce. It is already present in the female body. It is also used in many other medical treatments. Stuave not flagged major safety concerns. Even so, long-term data on children is still limited, as with many newer laboratory methods.

No. While embryo glue may help, nothing is ever guaranteed. Embryo glue can help some women conceive, but research shows mixed results.
The embryo glue step happens in the laboratory, so you don’t feel anything more than you would in a standard IVF procedure. The transfer itself is usually quick and gentle.
Yes. You can use embryo glue for fresh and frozen embryo transfer.
So far, studies have not shown embryo glue to pose any risk to the baby, as hyaluron is a natural substance. Long-term data is still limited, though.
Not necessarily. Many couples have had successful pregnancies without embryo glue. Be sure to discuss this thoroughly with your fertility specialist.
