somebody once told me that guys hold their x chromosomes on one of the testes separated from the y chomosomes which of course are on the other testes and that when you ejaculated both come up and mix in..... meaning that if a guy was to have a problem in one of his sacs he would have trouble producing that gender/chromosome.... what do you guys think?.... can it be true?

This is why you shouldn't learn about sex from your friends! Each sperm has either an X chromosome or a Y chromosome because each sperm has half of the guy's genetic code. But there are a random assortment of "girl" sperms and "boy" sperms in both testes. Spermatogenesis is the process by which stem cells (which contain the man's entire genetic code) produces sperm cells. If you want to know how this really works, read the linked article.
PS Rabbit is wrong. Each sperm and each egg contain only a half-set of chromasomes (23).

Someone is pulling your leg. Each of the millions of little wigglers that get ejected and sent on the way to a woman's egg carries a full complement of genetic code, which includes both an X and a Y chromosome pair. It is in your then-fertilized egg that your XX and his XY chromosomes meet and do their little trade off, discarding the unselected material. The result could be your mother's X and his mother's X, and you will have a girl. The result could be your mother's X and his father's Y, and the result will be a boy. A genetic switch will click one or the other chromosome off , or segments of them, and the child will resemble slightly more of your mother or his mother or father. But for most of the child, the mix is even more complex, each sperm cell, no matter which testicle it came from, has the same potential genetic information.

Chromosomes are present in the cells not testes. The germ cells contain the sex cromosomes. The germ cells modify overtime to form the sperms. When u ejaculate, the semen(which is a fluid of the same origin as lymph and mocous), carries the sperm into the female's uterus through the vagina. It is true that a boy receives his x chromosome from his mother and his y chromosome from the father.

wow people, so what you are saying is that the genetic code is bsically cut in half and physically distributed among each testis? a spermatozoa and an oocyte are haploids. Meaning that they contain half only one set of their genetic code (each cell has two sets of genomes, which is why there is dominance, ur moms and ur dads). When the sperm reaches the egg the two genomes then unite into a single diploid cell. A person that loses a testicle can still be completely fertile and have several kids. So I hope i helped.
PS- i no everyones attacking rabbit, so i will too, XX + XY = klinefelters or downs syndrome or other sex linked genetic diseases.

That's complete nonsense.
All men have an X AND a Y chromosome in every cell except for their red blood cells (no chromosomes) and their sperm cells.
The sperm cells have an X OR a Y completely at random and completely independently of the testicle in which it happens to be sitting waiting for the happy event.

No. Both XY chromosomes are everywhere in the every cell of the body just like all the other chromosomes.

That is ridiculous
Rabbit: You are suggesting that sex cells are diploid when they are actually haploid, so you are wrong. Half a genetic code from the man and half from the woman makes a full set for the zygote to grow into a normal fetus and then baby.

No each chromosome that a guy has has one x and one Y.

WOW! So many people don't know basic facts about the reproductive system. So far only 'just wondering' has offered up accurate information about human chromosomes... please ignore everyone else, for your own good.

No, that's not true. The X and Y chromosomes are together in the sperm.
