Sadly I no longer have any such access. Anyone in university able to shed some light on these
Hypnotic sex change: creating and challenging a delusion in the laboratory.
http://www.ncbi.nlm.nih.gov/pubmed/7897055
and
Information processing during hypnotically suggested sex change
http://www.ncbi.nlm.nih.gov/pubmed/11430157
Could be some interesting info in those - I can only see the abstracts though.
