Infertility/Fertility/B chorionic gonadotropin after IVF


Hello from Greece

My wife had an IVF and three embryos were planted.14 days after the IVF the B chorionic gonadotropin was 7.The doctor told us that she should had another one and after two more days the B chorionic gonadotropin is 13.
What is your opinion?Is there any change that she is pregnant?I know that B chprionic gonadotropin is very low but it get doubled so what that may mean?
Thank you very much

Hello George from Greece,

Yes the level is low but it is positive and it has risen appropriately.  We say that it should double every other day, but it really only needs to go up 80%.  The treatment at this point would be to follow the bHCG at least three more times to confirm that it is rising appropriately.  This should be a blood test every other day.

Good Luck,
