Acronyms used in Infertility and Surrogacy

Every profession has their own special list of acronyms that they use every day. Surrogacy and infertility is no exception! This list is dedicated to our profession’s special blend of alphabet soup.

Now you can confidently nod knowingly when we ramble on that “we’ve got FX for the 2WW” or that the “OB wants GS on MAT LV now.” You know you’re one of the cool kids when you high five your fav’ GC with an early H&H9 because their HPT POAS looks like a BFP — gotta wait for that OB confirmation, but always sending those ELV!

We’ve added all the ones we can think of, but there may be more. HTH, YMMV.
