Normal humans have 46 chromosomes (23 from each parent). Males with Klinefelter's Syndrome have 47 chromosomes and therefore have acquired an extra chromosome from a parent (hopefully a more knowledgeable contributor will say if it is from the male or female parent). A lot of studies have been done on the male calico cat. Back in the 1980's if one found a male calico cat that was NOT sterile, the cat was worth about 30K... a lot of money for that time period. I am not sure if similar hunts are currently underway.
Klinefelter's syndrome
With Turner's Syndrome, the females actually have 1 less chromosome, not an extra one or sometimes only part of the X chromosome is missing. Klinefelter's syndrome, 47, XXY, or XXY syndrome is a condition in which human males have an extra X chromosome. While females have an XX chromosomal makeup, and males an XY, affected individuals have at least two X chromosomes and at least one Y chromosome.
Most of the Klinefelter Syndrome affected persons can lead a life which could be considered as normal. However, they might have certain problems related to sexual organs, (among others), and some, - but not all -, could be infertile. The reason for this is their extra chromosome. Females have XX chromosomes, Males have XY chromosomes, and Klinefelter syndrome affected males have XXY chromosomes. They often are prescribed testosterone therapy. More info could be found on related links.
Lowe syndrome is caused by a mutated gene on the X sex chromosome. Because it is X-linked, it occurs almost exclusively in males.
About 1/1000 to 1/500 males have Klinefelter's syndrome.

Klinefelters Syndrome
First a testicular biopsy should be done to determine if he has any viable sperm. Some men with this condition do have some viable sperm in their testicles and if he does, in-vitro fertilization may be a possibility. However, if he does not have any viable sperm, then you would need to use donor sperm to become pregnant. Hope this helps.
Most males with Klinefelters syndrome have sufficient physical and potentially mental development issues to render them unsuitable for millitary service. This does not preclude the fact that there are always exceptions.

No it is caused by the Non-Disjunction of sex Chromosomes. Males with Klinefelter's syndrome have an extra X chromosome.

Males with Klinefelters, often have lower testosterone & additional breast tissue, weaker muscle tone. Sexual function is usually normal but Low sperm count is also common.
The X chromosome is affected, because there are 2 of them (and a Y chromosome).
It could be a problem very early in development (during pregnancy). About 1/3 of all males with Klinefelter syndrome have other chromosome changes involving an extra X chromosome.This syndrome isn't considered an inherited condition.Klinefelter's syndrome is not hereditary. And males who have this disease are infertiled. It means that they can't produce offspring because they can make few sperms.
Males are affected with Bassen-Kornzweig syndrome with greater frequency (70%) than girls, which is uncharacteristic in most autosomal recessive conditions.
