Final answer:

Progesterone's main role is to prepare the uterus for a fertilized egg, regulate the menstrual cycle, and help maintain pregnancy.

Step-by-step explanation:

The chief function of progesterone is the preparation of the uterus to receive a fertilized egg. This hormone is vital in the regular menstrual cycle, as it works in conjunction with estrogen to bring about changes in the endometrium. Additionally, progesterone helps in maintaining pregnancy after fertilization has occurred.
