Klinefelter syndrome, 47XXY

What is the Klinefelter Syndrome or 47, XXY?: Klinefelter's syndrome is a rare genetic disorder in which a man has an extra x chromosome. Certain conditions associated with Klinefelter hypothyroidism, infertility, testicular cancer and an increased risk for breast cancer, male testosterone deficiency enlarged breasts. (gynecomastia) sparse facial and body hair small hard testicles inability to produce sperm (infertility) chromosomes and Klinefelter's syndrome, 47XXY: People typically have two sex chromosomes in each cell. Females have two x chromosomes and males have one x and one y. males with Klinefelter's Syndrome often have one extra copy of chromosome X, for a total of 47 chromosomes per cell; This is defined (47, XXY). Some men with Klinefelter's syndrome have extra x chromosome only some of their cells; This is called "mosaic 46, XY/47, XXY." Additional copies of chromosome x interfere with male sexual development and functioning of the testicles, and explain some of the conditions mentioned above. Case of Klinefelter Syndrome: Klinefelter Syndrome is not an inherited condition, but occurs randomly. Is usually the result of an error that occurs during cell division during formation of egg or sperm. For example, an egg or sperm cell can have an extra copy of chromosome x cell division. If one of these cells is involved in the conception, the result is a child with an extra x chromosome in each cell of the body. When the error occurs early in cell division of fetal development (fertilization instead of before) the result is a mosaic, means that not every cell of the body is affected.Because 47XXY cannot be present in every cell of the body, every case is different. Not all symptoms may appear, and many cases go to be discovered. The most common concerns are: breast cancer, male infertility osteoporosis depression diabetes thyroid problems leg ulcers can be given problemsTestosterone dental theraputically, development of the body as a male advances in maturity. If testosterone is given for Klinefelter's syndrome, it must constantly be continued for life.

Hormonal therapy will not improve soil fertility, but testicular sperm extraction and in vitro fertilization can result in a pregnancy.

If an adult male has some distress about sexual identity, or sexual dysfunction, professional counseling can help.

Ratio of Gynecomastia and male Breast Cancer: Klinefelter Syndrome is associated with an increased risk of developing breast cancer. Gynecomastia (prominent breasts in a male) is a symptom of Klinefelter Syndrome. Having the extra breast tissue increases the risk of developing breast cancer.National Institutes of Health.
