I saw in a book called "the Elephant in the Playroom" and came across a confusing term:

It was called Turner's Syndrome and it said it affects girls who are lacking the X chromosome.

What I want to know is, what happens to a boy's body when he lacks the Y chromosome? What is the male version of Turner's Syndrome?

as far as i understand it, if there is no Y chromosome, it's not a boy.

unless you want to consider gender dysphoria in biological females to be a condition for a boy without a y chromosome. but that is not the same thing as what you are asking.

From what I have heard, current science says a man ***HAS*** to have at least one Y chromosome. If a womans primary sex differences were 100% deactivated from conception, she would CONTINUE to form as a female. If a male was even simply unaffected by actions from primary sex differences, the person would seem FEMALE!

BTW I am using the term differences instead of characteristics, because this difference would be BEFORE the characteristics, and would affect them.

Whoa, crazy thought here. You know how they've made female eggs undergo the process of fertilization with another egg? I wonder what the result would be from two Y chromosomes? We know XX is girl, XY is guy, but what would YY be?

I can see it now, ultrajocks, a new type of sports, a new breed of macho men. Get the National Leagues and the Village People on the phone, we've gotta get this experiment rolling! :lol:

I dont think a YY foetus would be viable. The X chromosome carries a lot of essential genes not otherwise related to gender.

There are XYY or XYYY males though. They are called "Super Males".

I think you're right. The X chromosomes have SO much more genetic material that some people have use centrifuges to seperate out sperm for males/females to have a child of a certain sex. They also claim the difference is increasing.

Good point; And the results might be a bit frightening. As well, we'd have no idea how the offspring born in such a way would even be like, or what kind of problems may be caused by their manner of conception... :?
Better off not knowing, perhaps. As they say, ignorance is bliss.

Turner Syndrome with a chromosomal complement of of a single X is characterized by primary amenorrhea, sexual infantism
with short stature and multiple congenital anomalies. The incidence is estimated to be one in 2500 newborn females.

Klinefelter Syndrome is (XXY) a male with two or more X chromosomes...this chromosomal disorder is the most frequent major abnormality of sexual differentiation, the incidence being around one in 500 men.

Yes, there can be an XX male...the findings resembling those of Klinefelter Syndrome. Affected individuals differ from typical
Klinefelter Syndrome males only in that the average height is less than that of normal males. The majority of XX males whose
DNA is probed with Y-chromosome DNA fragments containing the SRY gene are positive for Y-related DNA; thus, an X-Y
interchange appears to be the common cause of this disorder. The management of this chromosomal disorder is similiar to that
of Klinefelter Syndrome. The incidence of a male being born with two XX chromosomes is approximately one in 20,000 to
24,000 male births.

Any further information you would like to know, I will respond in a PM or you may find additional information through Wikipedia,
although it may not be entirely true.

This is true...I knew one. he found out he was XX when he had six daughters and was wanting a son. He was a biology teacher so he suspected something.

I don't know why some teachers mention these things to their students. He didn't seem to be joking.

Not quite, you just need the SRY-gene who is on the Y-Chromosome to appear male and there are some cases were this gene got relocated on an X-Chromosome and than you have a male with XX Chromosomes:
http://en.wikipedia.org/wiki/XX_male_syndrome

YY Chromosome individual WITHOUT an X Chromosome doesn't work.
Turner-Syndrome is also the only possibility a person with just 45 Chromosomes can survive.

XY Swyer syndrome 46,XY females exist.

Strange considering your chromosomes don't necessarily dictate your genatalia.

I myself is considering getting genetically tested for 47,XXY Karyotype test myself...

Why?
I may not, but I do possess the collection of syndromes and characteristics related within Klienfelters or of being XXY.

http://cme.ucsd.edu/ddhealth/courses/KLINEFELTER(XXY)SYNDROME%20.html

It's interesting and everything could be co-incidental, but I am investigating my current symptoms through psychology, neurology and occupational therapy before a doctor could suspect any actual need for a genetic test.
