Answer 1

The correct option is D

All the above

Progesterone is commonly known as the pregnancy hormone. One of the most important functions of progesterone is its role in thickening the lining of the uterus each month. This enriched endometrial lining is prepared to receive and nourish a fertilized egg. In other words, progesterone prepares the endometrium for implantation of the emryo. If a pregnancy occurs, progesterone is produced in the placenta and the hormone's levels remain elevated throughout the pregnancy.
