Embryo implantation is a complex process involving continuous molecular cross-talk between the embryo and the decidua. One of the key molecules during this process is human chorionic gonadotropin (HCG). HCG
effectively modulates several metabolic pathways within the decidua contributing to endometrial receptivity
.
Is hCG released before implantation?
HCG is the first known hormonal signal of the conceptus
How quickly does hCG rise after implantation?
About four to five days after implantation
bleeding, HCG levels in the body reach detectable levels in the blood. For at-home urine pregnancy tests, it may take up to 7 days for HCG levels in the urine to reach detectable levels for testing.

least 10-50 mIU/cc
in the 7-8 days following implantation.

What should you not do during implantation?
We recommend that you
avoid strenuous activity around the time of embryo transfer
. There is no evidence to support total bed rest to improve implantation rates and total bed rest is associated with other health risks.
Why hCG injection is given?
Human chorionic gonadotropin (HCG) is a hormone that supports the normal development of an egg in a woman’s ovary, and stimulates the release of the egg during ovulation. HCG is
used to cause ovulation and to treat infertility in women
, and to increase sperm count in men.
When can I take pregnancy test after hCG injection?
If you use a home pregnancy test after an hCG injection,
