Estrogen Dominance is the theory that estrogen is highly out of proportion compared to progesterone overall during the cycle. Both estrogen and progesterone are important for breast growth, so keeping them in proportion is necessary. Estrogen dominance may also be a sign of a low proportion of prolactin compared to estrogen.

Possible symptoms of Estrogen Dominance:
* heavy or frequent menstruation
* inverted nipple - is possibly a symptom of high estrogen, and low prolactin
* tubular breasts - is possibly a symptom of high estrogen, sufficient prolactin and low progesterone
* PCOS

Progesterone:
A higher proportion of progesterone is associated with light menstruation.
