I am mainly a lurker but I wanted to share some information with you ladies.
I have been researching from a scientific stand point what causes an embryo to implant and to continue to grow. I came across this article regarding hyaluronic acid and how it can predict if an embryo will implant. Ironically hyaluronic acid is the same ingredient found in embryo glue.
I questioned my RE regarding the use of embryo glue and he advised that he conducted a study using embryo glue and the outcome was not favorable. So I decided to supplement with it on my own and I purchased a bottle of Dr's Best Hyaluronic acid with chondroitin sulfate and have been supplementing with it for over a month. I plan to start an IVF cycle sometime this month and I sure hope this helps.
Please read this articlhttp://www.ncbi.nlm.nih.gov/pmc/articles/PMC2582091/
This article explains that you must have a sufficient amount of hyaluronic acid in your system in order for the eggs to implant. If you want more information please let me know. I hope this helps all of you.
