Why can't boys get turner syndrome?

Answer 1

In the vast majority of people, they are either male (having one X chromosome and one Y chromosome) or female (having two X chromosomes) in every single cell in their body. In people with Turner's syndrome, however, their cells have only a single X chromosome. For this reason, Turner's syndrome is sometimes referred to as an "X-O" disorder (to differentiate it from the state of being male - XY, or female - XX).

Because Turner's syndrome sufferers do not conform to the traditional notions of genetic maleness or femaleness, then, it would be improper to define Turner's as either a male or a female syndrome. Its sufferers are neither.

In Addition:

There is a form of Turner-like Syndrome which affects a male children; this form is called "Swyer Syndrome." These male children are NOT born with functional gonads (testicles); the gonads are NOT on the outside of the body as normal, they are inside. For all intense purposes, these children appear to be female with abnormally enlarged female genitalia, but this deformity is actually a small penis. So therefore, the sex glands are ambiguous, the penis does NOT appear to be a penis, nor will it ever function normally. So it is usually suggested by their doctors, that these children be raised as "girls." Right or wrong, this is usually done for the child's sake, with the thought that it will make their life's easier in the long run to be raise as a girl, and in many cases it works out.

Answer 2

Females normally have two of the same sex chromosomes, XX. Males have an X and a Y chromosome, XY.

In Turner Syndrome, cells are missing all or part of an X chromosome.

A boy can't survive with only a Y chromosome because it cannot function by itself; it needs an X. Just think of it like a marriage. Men (Y) just can't function without women (X).

Answer 3

Because the SRY gene ( the sex determining region ) is on the Y chromosome. One X, as in Turner's syndrome and you have a female. Even if the SRY region ended up on that single X ( rarely happens ) you would still have a male fetus.

Rare? I would say impossible.
