From this we can see...
Inverted nipples:
Considering how PrlR are contained in the nipples, it can be seen how endogenus prolactin may be helpful for inverted nipples. Prolactin's imporance is during menstruation. Massage increases prolactin, which is normally higher during sleep. Mood may be important too, or at least a decrease in stress. Perhaps inverted nipples are an indication of a longterm excess of estrogens, compared to prolactins.
Tuberous breasts:
Also note how endogenus progesterone, which causes lateral growth and lobule development, may be helpful for tubular breasts. Progesterone must be balanced during the luteal phase, but it must be balanced by estrogens to lower pms symptoms. Aromatases are important for estrogen production made from testosterone.
Breast firming:
Progesterone receptors (likely PRB) are contained in the ligneous tissue (cooper's ligaments) of the breast. Progesterone may be important for breast firming.
