A member asked:

Does hcg get produced when the blastocyst starts to implant or when it's fully implanted?

Specializes in Fertility Medicine

Can't say: Scientifically this is nearly impossible to answer (when it is produced,) but hCG is not detectable in blood or urine until several days into the process (whenever the production started).

Dr Fowler agreed
