As I have read something about scientists to be able to detect some type of notes in the hypothalamus structure in which the size of these in there are somehow related to the sex or sexual orientation of the person; and all this is determined by the information which comes about in the DNA of each and every one of us. Anyway an issue which is way out of my full understanding but one that is very interesting for which I am sure in the future there is much talk and debate to come about.

Txs for your reply. Rgds.
