One extra sex chromosome

Klinefelter syndrome - Chromosome X. Its signs and symptoms vary among affected individuals and may include small testes that do not produce enough testosterone, which causes a delay of puberty or incomplete puberty, gynecomastia, reduction of facial and body hair and infertility; cryptorchidism; hypospadias and micropenis. Other physical changes associated with Klinefelter syndrome may include radioulnar synostosis, clinodactyly in the fifth finger and flat feet; hypotonia and coordination problems that delay the development of motor skills. Older children and adults with Klinefelter syndrome tend to be taller and have a higher risk of developing type 2 diabetes, blood clots, tremors, breast cancer and systemic lupus erythematosus, although the likelihood of developing these alterations is similar that of women in the general population. In addition, children with Klinefelter syndrome may have learning disabilities and delays in speech and language development. Also, they tend to be calm, sensitive and assertive, although personality characteristics vary among affected individuals.

Klinefelter syndrome and other sex chromosomal aneuploidies

Klinefelter syndrome usually occurs randomly. While no cure is known, a number of treatments may help. Klinefelter syndrome is one of the most common chromosomal disorders , occurring in one to two per 1, live male births. While XXY males can possibly be characterised based on physical characteristics, substantial variation in physical and developmental traits mean the only reliable method of positive or negative identification is karyotype testing. As babies and children, XXY males may have weaker muscles and reduced strength.

Cells from mice with an extra sex chromosome can be returned to normal by reprogramming them into stem cells. Mitinori Saitou at Kyoto University in Japan, James Turner at the Francis Crick Institute in London and their colleagues took fibroblast cells from mice rendered infertile by having three sex chromosomes — either an extra X or an extra Y. They reprogrammed these fibroblasts into pluripotent stem cells, which they then converted into immature sperm cells and transplanted into mouse testes. During the reprogramming, the cells lost their extra chromosomes.

    I think this is great. Couples need to leverage their partners strengths. My hubby sucked my boss dick( actually quite a few times and it led to my getting promoted. I dont feel bad about it at all. Hubby is cute, boss loved it, and hubby kept going back so apparently he liked it too.

    And me, love to add my spunk as well.
