Naomi,

In addition to the N.Y. Times report by Natalie Angier (May 24, 1994, p.
B5) mentioned already, here is a blurb about the research from a newsletter
called Weizmann NOW, from the fall of 1994:

"A group of Weizmann researchers made front page news with mother's milk.
They showed that in lactating laboratory animals, the mammary gland
produces a peptide hormone crucial to regulating development of the human
brain and sex organs.  In human milk, the GnRH peptide also occurs in high
concentrations.  'Mother's milk should not be regarded as a mere source of
nutrition, but as a major stimulator of developmental physiology,' said
Prof. Yitzchak Koch (Stevenson Chair), Department of Hormone Research, who
headed the multidisciplinary team."

The research was done at the Weizmann Institute, Rehovoth, Israel.  You
might be able to learn more from them.
