Hi Perlita and regan.
Been reading on the connection between the
Found this synopsis which appears to sum the theory up quite well.

http://www.annelawrence.com/twr/brain-sex_critique.html I get the impression, by reading this and some other information on this woman, that she may be a little disturbed. Sad. Never-th-less, it is quite interestng, if only to force you to remember the actual details of the research, rather than the version of Ms Lawrence.
This one which was referred to by Perlita. I confess, I haven't studied this one in any detail. I've already read the others quite carefully. This one has considerable detail. I'll keep it for reference.
http://jcem.endojournals.org/cgi/content/full/85/5/2034And finally, this one. Which is the principal source I've used.
http://www.jneurosci.org/cgi/reprint/22/3/1027.pdfThe area is described, in a number of sources, as being part of the anxiety and stress response.
Now I know, form clinical observation, that anxiety and stress response are not sex dependant. Both sexes can experience these as a disorder, in similar fashion, though men, most likely for social reasons, tend to be less forthcomming with symptoms and asking for help. (Actually, it's probably just as well. In my experience, when men have crumbled to the point that they are in pieces, they rarely get any sort of positive reaction from anyone, including health professionals. A possible throwback to the custom of the honourable suicide??).
But I'm curious as to the actual function of this organ and the relationship between size and function.
The principal difference I've observed, beween men and women is their differing social response, their almost universal customs in peer group forming.
(I've made reference to models of male and female peer groups in other threads. I get the impression that some here seem to dislike these models. I apologise for this. I find it easier to think in pictures. I will give brief resume of the model I use, if only for the humour).
Males tend to form themselves into pyrramid shaped peer groups where their competitiveness seems to be directed at seeking to undermine those in more secure positions, usurp, or to those that seek to imfultrate, putdown. Generally, their agressivness tends to be confined to those they are actively seeking to undermine, including other peer groups. It also appears to be, generally, short lived.
Females tend to form themselves into peer groups more akin to a flat line, with a bump near the centre, or to on side, indicating the apha. The members of the female peer group, apart from the alpha, seem to be less conscious of hierarchial status, other than their physical proximity to the alpha, which is invariably fluid. Their agression toward those they are rejecting appears to be more persistant and so, ultimately, more vicious and personal, if only because of its persistance.
A further difference appears to be that in male peer groups, acceptance into the group appears to be almost by general acclamation, while in female peer groups, the alpha seems to be the factor.
I'm attempting to rationalise the differing social organisation of males and females with this differing brain function. I don't know of any differnce in relation to stress response, since both seem to have an equal variation in this regard.
Yet, since this appears to be the principal difference in brain anatomy between males and FtMs and females and MtFs, there should be a relationship. If not in the social behaviour, then is some other innate behaviour which is marked by sex differences.
Second point.
The main article suggested that the difference in structure of this organ seems to emerge in adulthood. Is there a possible relationship to the ultimate irregularity of this structure in transgendered individuals and their desire, in childhood, to adopt an opposite gender? (The implications are rather horrific to be honest).
Third point.
How many transgender individuals have been found not to have this physical irregularity?
Has any invstigation into the behaviour and relationships been done on those, not profession to be transgender, yet haveing this physical iregularity?
