Progesterone Breast Growth
Progesterone works in partnership with estrogen during a woman's menstrual cycle, preparing her for a possible pregnancy, and contributing to an increase in her breast size. Estrogen stimulates the growth of breast tissue while progesterone causes water retention.

Water Retention
-
When a woman retains water, her breast tissue stretches to accommodate the excess fluid. The stretching prompts breast tenderness and discomfort. Your breasts actually do get larger as a result of water retention.
The Need For Fluid
-
Ovulation occurs when progesterone levels rise and estrogen levels decline. Even though water retention makes you feel fat and uncomfortable, there is a need for this excess fluid. In the event that you become pregnant, the uterus is full of water and food, making it ready to host the embryo.

Milk Producing Cells
-
In addition to increasing fluid in a woman's body, progesterone also stimulates the development and growth of milk-producing cells, which increase breast size.
Progesterone Increases Cell Size
-
The lobules and alveoli of the female breast become more developed because of progesterone, which causes the alveolar cells to get bigger and become "secretory" in nature (milk-producing).
Identifying Parts of the Breasts
-
Each lobe in a woman's breast is made up of smaller lobules. Milk is made in the lobules. The lobules and lobes are attached by small tubes called ducts. The ducts carry the milk to the nipple, according to Womenshealthzone.net. The alveoli is a hollow cavity that is lined with the milk-secreting cells. The alveoli form groups of lobules.
