Klinefelter's Syndrome

Klinefelter syndrome is caused by the presence of an extra X chromosome in males due to a random error in cell division, known as nondisjunction. This results in a chromosomal mutation where males have an additional X chromosome, leading to physical and developmental differences.

Klinefelter's syndrome affects approximately 1 in 500-1000 males. It is caused by an extra X chromosome, resulting in symptoms such as small testes, infertility, and reduced testosterone levels. Early diagnosis and treatment can help manage the symptoms and improve quality of life.

A male with Klinefelter's Syndrome (XXY genotype) would have two Barr bodies in each cheek cell, as they have an extra X chromosome. This extra X chromosome forms Barr bodies inactivated during embryonic development, leading to the presence of two Barr bodies in cells with two X chromosomes.

Individuals with Klinefelter's syndrome have an extra X chromosome, resulting in a total of 47 chromosomes, with the usual sex chromosomes XX for females and XY for males being XXY in individuals with 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.

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.

No. The main effects of klinefelter syndrome are development of small testicles, small penises, lower testosterone levels and reduced fertility

While that is true, there have been extreme advance in the use of fertility methods and while it isn't going to be 100% effective there is a higher chance than 0%.

Additionally, penis size is irrelevant when talking about fertility. Most Klinefelter's patients have normal sizes. The problem is called hypogonadism; reduced use of the testicles. The above poster is correct that with genetic counseling, there are relatively good chances of finding viable spermatozoa. I believe that early diagnosis is essential to finding and freezing the spermatozoa, which increases chances by a good amount. Source - I have it.

X-inactivation typically occurs in individuals with Klinefelter syndrome, which is characterized by having an extra X chromosome (XXY). However, the extra X chromosome in Klinefelter syndrome may not undergo inactivation completely, leading to some cells expressing genes from the additional X chromosome. This can result in a variety of symptoms and characteristics associated with Klinefelter syndrome.

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.

People with Klinefelter's syndrome (XXY) and Turner's syndrome (XO) can still have children through assisted reproductive technologies like in vitro fertilization. Additionally, many individuals with these syndromes may not be aware of their infertility at a young age when they may still have the opportunity to have children. These genetic conditions are also not always inherited, so they can arise independently in a population.

Klinefelter Syndrome is a genetic condition that occurs in males when they have an extra X chromosome. This can lead to infertility, reduced testicular size, and lower levels of testosterone. Some individuals may also experience developmental delays or learning disabilities. Early diagnosis and management can help address symptoms and improve quality of life.

Carbon dioxide is produced as a byproduct of cellular respiration in organisms, including humans and animals. During respiration, glucose is broken down in the presence of oxygen to produce energy, water, and carbon dioxide.

HLA (Human Leukocyte Antigen) is called an antigen because it is a protein on the surface of cells that plays a crucial role in the immune system. When the immune system recognizes foreign antigens, including those of HLA, it triggers an immune response to protect the body from pathogens.

yes

I personally take cypionate testosterone, for the low testosterone my body produces.

It helps produce more testosterone, body hair, muscle, and reduces body fat.

It can not be successfully treated.. but testosterone supplements can make you live a normal life minus some features..etc..

You would have to take these shots, patchs, or gels to live the life as a normal adult/child for the rest of your life.

I personally take them as shots. which seems to work better than Gels or patchs. Gels you put on your shoulders/back, but they can come off when going into water/pools/ocean. Patchs leaves marks on your body, and you mainly have one on your thigh, back, or stomach. The shots are a quick deal they normally go for the buttocks. Because ... it's the biggest muscle and for appearance no one is checking it out :)

By definition Klinefelter's syndrome is genetically XXY. If there is any Y chromosome present, the baby will develop into a boy.

Even if a baby had XXXXY, it would still turn out as a boy.

Klinefelterâ??s syndrome is the result of additional X genetic material in males and typically causes low testosterone levels, gynecomastia, and infertility. Though there are no documented famous people with this syndrome, some believe that George Washington may have been afflicted.

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.

Klinefelter syndrome can result from errors in cell division of sperm or egg cells. With this syndrome, each of the cells of the person affected will have an extra X chromosome.

Klinefelter = XXY

Turner's = X

Klinefelter syndrome is the extra X and can lead to somewhat of a female secondary sexual characteristic in men.

Turner's is the single X some women receive and can cause short stature and lack of secondary sexual characteristics.

non disjunction of sex chromosomes

Klinefelter Syndrome is a genetic condition that affects 1 in 500 to 1,000 male babies. That’s caused by an extra copy of the X chromosome in each cell. (You may recall that humans typically have two chromosomes: females have two X chromosomes, while boys have one X and one Y. For that reason, Klinefelter is sometimes called XXY Syndrome. That extra X causes a number of symptoms, most of which have to do with male sexual development (other symptoms may include learning disabilities, behavioral problems, speech disorders, and problems with balance and coordination). Boys with Klinefelter typically have smaller-than-normal testicles that produce less-than-normal amounts of testosterone. As a result, a Klinefelter boy who’s entering puberty may have little or on body or facial hair, undescended testicles, and sometimes breast development (called gynecomastia). That said, some men have few symptoms and only realize that they have Klinefelter’s when they have trouble impregnating their partner: About 95% of men with Klinefelter’s are infertile. You can get more information on Klinefelter’s here.

It is a condition in which human males have an extra X chromosome. It is inherited when the extra X chromosome is retained because of a nondisjunction event during meiosis I (gametogenesis).

The karyotype of a person with Down Syndrome differs from a normal karyotype because it contains a three chromosomes in the 21st slot, where there should only be a pair of two. That is why this is called Trisomy 21.
