Answer:
The hormone is progesterone.
Explanation:
After fertilization, progesterone is secreted from the corpus luteum. The corpus luteum originates from an ovary at the site of a follicle that has matured and ruptured during ovulation. The corpus luteum plays a role in regulating menstrual cycle and early pregnancy. In early pregnancy, the corpus luteum secretes progesterone to prepare the endometrium for implantation and subsequent maintenance of pregnancy.
