Hi ppl, is anybody in the club? Am I too early or seriously late?

What "Fishy" stuff is going on? All I know is that certain type of reptiles can change the sex of their eggs from male to female or vice-versa according to the need of the species. Cool huh? I think they just adjust the humidity and temperature during the incubation.

I say wise-girl this sounds a little contradictory.

how a person can have an identity contrary to their sex has to do with hormone levels in the womb after brain development and before sex expression

Since we know that sex is determined during the union of sperm and ovum. As the cellulor nuclei combine and fuse their genetic content during zygote formation, sex is determined by the type of chromosome in the donated sperm.
If the sperm is Y type, then the resulting cell will become XY (as the egg is always X) and a male baby will ensue.
If on the other scenario, the sperm is X type, the baby will be female or XX.
The rest of the nine months of pregnancy is just duplication of the same cell bearing the same resulting gene to form the millions of cells that construct this body. Although cells take up different functions and form different tissues and ultimately the various organs, etc. Brain cells, heart cells, bone cells, muscle cells and so on.
My point is sex is NOT determined after brain development, it is done immediately after the fusion of the sperm and ovum.

At it's most simple, yes. But XX/XY are not the only chromosome combinations, XXY and XYX for example, an estimated 20% of the population does not have a tidy XX/XY chromosome combination.

Even so, what I was talking about was called "estrogenation". The foetus, developing as normal, will sometimes be exposed to higher than normal levels of estrogen. The theory is this affects the way the foetal brain develops since this. Extreem estrogenation is thought to be one of the reasons for intersex births (children born with "ambiguous genitalia" or rarely hermaphrodytism). Perhaps a less extreem change in the hormonal soup that surrounds a developing foetus would cause the conditions that lead to Gender Identiy Disorder or Gender Dysphoria.

Good conversation.. I like this

Ya ya doctor, but not all that comes out of those luscious lips are true.
Exhibit some reliable references and I will agree. As I am offering you.
1) Prior to & during pregnancy, a hearty diet consisting of lots of sugar, rich in nutrients, Na (sodium), Ca (calcium), Vit-C, E, B12 increase chances of having a male child. ~ {study, published in the U.K. journal, the Proceedings of the Royal Society B. Related to: Fiona Mathews of the University of Exeter in England }
Actually this diet tampers the ph level , the acid-alkali balance is taken to an optimum condition which encourages the Y-gened-sperms to flourish easily inside the uterus. (and perhaps hinders the X-sperms?) (actually some sperms even meet the ovum inside the Fallopian tube!)
Ref site.

2) In ayurveda and yoga books some are of opinion that if the blood of the mother is Alkaline during mating, the child will be male; and acidic will lead to female.
