Summary Introduction
To review:
The correctness and incorrectness of the statement, “Whether corpus luteum is retained upon implantation in the presence of the hCG (human chorionic gonadotropin).”

The hCG is the hormone, which prevents the degeneration of the corpus luteum. The hCG helps retain the corpus luteum upon implantation. The hormone is produced by the placenta after the implantation of the embryo.
