S. Puterbaugh writes: "Right now, my own impression is that human sexuality is built upon a very strong genetic foundation which is probably modifiable by hormonal events within the womb." Recently I read in my newspaper an article about a (new?) book: The Mona Lisa Syndrome (this is the title in Germany), written by the British biochemist and medical Prof. Leon Kaplan (Oxford University). As I did not read this book myself, I can only summarize its principal contents after that newspaper article: Kaplan claims to have found out that homosexuality in both sexes is caused by a certain hormonal disorder in the mother's organism during certain periods of pregnancy. The main reasons for this hormonal disorder (i.e. mainly lack or excess of testosterone) seem to be stress (!!) and naturally induced oscillation of hormone levels over the year. I remember that some years ago I read about the research results of a professor for psychology at the Humboldt University in East Berlin. Unfortunately I do not remember his name. He had interviewed many (male) homosexuals and finally found out, that most of their mothers had suffered from severe stress of different kinds during pregnancy. This would fit the abovementioned results. Peter Diercks, Hamburg, W. Germany
