Susan,
I would think an endocrinologist could sort things out.  Is there one on-line
with us?
I looked in Ruth Lawrence's "BF - a guide for the medical profession" but I
do not own the newest edition. Chapter 3, 3rd ed, is Physiology of lactation
and gives detailed info on hormonal preparation of breasts during puberty,
menstrual cycles, pregnancy, etc.  Chapter 15 is Medical complications of the
mother, but I did not see anything on polycystic ovaries.  Perhaps newest
edition addresses this. From reviewing these chapters it seems that estrogen
and progesterone are needed for breast development during puberty and pg
(ductal, lobular, and alveolar devel).  But once baby is born, they are not.
 So does mom have the breast development? I don't know.  The intricacies of
all the glands and hormones is a very complex topic and a bit over my head,
and again I would refer to endocrinologist.  Lactnet is so humbling.  We
learn so much, but we find out even more about what we don't know. Anyone
with expertise in this area, please share.
