Human chorionic gonadotropin

 

Gonadotropin produced in the placenta and prior to the formation of the placenta, by the trophectoderm is the human choronic gonadotopin. It acts on the ovary to maintain the corpus luteum of menstruation, which it converts to corpus luteum of pregnancy.

 

Hormone produced by syncytiotrophoblastic tissue of the early embryo. It is responsible for providing gonadotropins that allow increase levels of sex steroid in early pregnancy up to 12 weeks. After this period, the placenta itself produces steroids for the rest of  pregnancy and the human chorionic gonadotropin declines.
