Human chorionic gonadotropin (hCG), progesterone, 17β-estradiol, endorphins and gonadotropin-releasing hormone (GnRH) synthesis are rapidly upregulated by the developing embryo following fertilization of the ovum. [1] [2] [3] During early embryonic development, paracrine/juxtacrine signaling of hCG induces blastulation and neurulation.
