I think any male hormone could decrease the milk supply very
signficantly.  What sort of an idea is it to test women for male
hormones when they have heavy vaginal bleeding?  This seems odd to me,
but gynecology is a long long time ago for me.

Why don't you ask Victoria Johnson, a ob/gyn who occasionally posts on
lactnet.  I will send you her email address privately.
