Final answer:
MGA and Norgestomet are synthetic versions of the hormone progesterone, which is used to synchronize estrus in livestock.
Step-by-step explanation:
The hormone's synchronization products MGA and Norgestomet are related to progesterone, which is a hormone involved in the reproductive processes of mammals, including the menstrual cycle and pregnancy. MGA (melengestrol acetate) and Norgestomet are synthetic versions of progesterone used to synchronize estrus in livestock for breeding purposes. The role of progesterone in the reproductive cycle includes preparing the endometrial lining of the uterus for potential implantation, maintaining pregnancy, and influencing the secretion of other hormones such as LH and GnRH.
