	=== Progesterone ===		=== Progesterone ===
			The scientific studies are sparse, and the opinions of doctors are extremely varied, but anecdotal reports by many transgender women imply that progesterone is a useful and necessary hormone in the development of their breasts.

			For more information about progesterone and the current science around it, read the [[Progesterone]] estrogen.fyi page.

			The TLDR is: it is known that progesterone allows water weight to move to more feminine areas. Due to a lack of scientific scripture, we cannot definitively say any more information.

			Specifically, this is referring to the use of the Tanner scale, where we learn that an increase in estrogen causes the lactiferous duct system to develop at T2 (~age 9-10), and later an increase in progesterone causes the lobular alveoli at the ends of lactiferous ducts to increase in number at T4 (~age 12-13)<ref>https://www.ncbi.nlm.nih.gov/books/NBK534827/</ref>

T5 - Up to 5 years. Areola moves back and flattens out but not completely. The diameter of the areola reaches its maximun. The breast reaches mature size and fullness.
