Educational support can teach boys ways to keep pace in school. Some might be eligible for an individualized educational program (IEP) or 504 education plan, which are designed to help children with specialized needs.

Aneuploidy is the condition of having less than (monosomy) or more than (polysomy) the normal diploid number of chromosomes. Aneuploidy occurs in at least 5% of all pregnancies and is the most commonly recognized chromosome abnormality in humans. (16) Divergence from the normal number of X and Y chromosomes, called sex chromosome aneuploidy (SCA), accounts for approximately half of all chromosomal anomalies in humans with a total frequency of 1:400. (17) Sex chromosome physical abnormalities are able to be diagnosed prenatally via amniocentesis and chorionic villi sampling (CVS). Prenatal diagnosis of SCA is increasing because of the widespread use of these technologies. (18)Early inventions should be considered at infancy for physical therapy, at 15 months for speech delay, at 1st grade for reading and learning issues, and at 3rd grade for anxiety or depression.Since it's impossible to correct every sex chromosome in our bodies, there is no treatment for XYY syndrome.

What Is XYY Syndrome?

Congenital adrenal hyperplasia (CAH) is an inherited autosomal recessive condition that can affect both boys and girls. It is the most common cause of intersexuality in females with 46XX, where untreated girls develop an outwardly male appearance. This disorder, also called adrenogenital syndrome (AGS), results from a genetically caused deficiency of cortisol, a steroid hormone produced by the adrenal cortex. The disorder occurs with a frequency of 1:5000 and results in incomplete female sex differentiation and increased androgenic effects due to a compensatory increase in adrenocortical hormone (ACTH). (33) Chromosome aberrations are classified as one of two types: numerical or structural. Chromosome structural changes include a wide variety of rearrangements including translocations, inversions, rings.. Typical sexual development is the result of numerous genes, and mutation in any of these genes can result in partial or complete failure of sex differentiation. These include mutations or structural anomalies of the SRY region on the Y chromosome resulting in XY gonadal dysgenesis, XX males, or XY females; defects of androgen biosynthesis or androgen receptors, and others.

Options vary greatly depending on how old a boy is at the time of his diagnosis, whether he has noticeable symptoms, and the severity of those symptoms. Men inheriting an additional Y chromosome are usually taller than average and are prone to acne because they produce higher than average levels of testosterone. Affected males are typically fertile and many are unaware that they have a chromosomal abnormality. The frequency of males born with an additional Y chromosome is approximately 1:1000.

‘True’ hermaphroditism is a genetic condition in which affected individuals have both mature ovarian and testicular tissue. (29) There are no published population-wide estimates of the frequency of true hermaphrodites. (30) The autosomal inheritance of this condition suggests that genes controlling sexual development and differentiation are not limited to the sex chromosomes.(31) Blackless et al. suggest that such familial inheritance “opens the possibility that, as with other inherited forms of sexual ambiguity, there may be pockets, perhaps even large geographical regions, with relatively high frequencies of true hermaphroditism.” (32) XYY syndrome is a rare chromosomal birth defect that occurs when a male infant is born with an extra Y chromosome. Instead of having one X and one Y sex chromosome, those with XYY syndrome..

Occasionally, a child is born with 47; if the extra chromosome is a Y chromosome a boy is born with XYY syndrome. This has nothing to do with the parental age, health or ethnicity. It's not inherited, it's an accident at conception. Most boys with XYY syndrome can grow up healthy, have normal sexual development and fertility, and lead productive lives. Category:XYY syndrome.

If one chromosome is missing from a pair of chromosomes and is thus present only once instead of twice as usual, this is known as „monosomy“. In monosomy X (also known as Turner syndrome or Ullrich-Turner syndrome), the second sex chromosome is missing. It is the only viable monosomy in humans, affects only girls, and occurs approximately once in every 2500 female infants.Triple X syndrome (XXX) / Trisomy XIn so-called triple X syndrome, three copies of the X chromosome are present.

  3. Sex chromosome abnormalities are gender specific.  Normal males inherit an X and a Y chromosome while females have two X's.  A single Y chromosome is sufficient to produce maleness while its absence is necessary for femaleness.  Female abnormalities are due to variations in the number of X chromosomes.  Male abnormalities are the result of irregular numbers of either the X or the Y chromosome or both.  
  4. Those with the syndrome experience puberty at expected times, as well as normal development of sex organs and of secondary sex characteristics.

The high frequency of individuals with SCA is due to the fact that their effects are generally not as severe as autosomal abnormalities and are rarely lethal. Indeed, most cases of SCA are compatible with normal life expectancy and often go undiagnosed. (19) Still, it is estimated that1 in 3 miscarriages is due to aneuploidy affecting the foetus. (20) The induced abortion rate for SCA has steadily decreased from 100% in the 1970s to 69% in the 1980s and 49% in the 1990s. (21) It has been suggested that this decrease is directly the result of improved knowledge of the conditions associated with SCA combined with the influence of genetic counseling. (22) It was a Friday when a sample of blood was taken from my baby's liver for tests, and after a terrible weekend of waiting, my obstetrician said: 'It's all right, it's only XYY syndrome.' And that was it in terms of medical explanation.

I struggled on like this for three months, imagining myself to be coping, hating myself for being foolish enough to get into this situation. One day I had to take Ted to the doctor because he had a bad cough. 'That baby's too fat and you look awful,' he said. Early studies of XYY syndrome done in European prisons initially led to the erroneous conclusion that these men were genetically predisposed to antisocial, aggressive behavior, below average intelligence, and homosexuality.  Contributing to the early view that XYY syndrome men have serious personality disorders was the case of Richard Speck.  In 1966, he coldly murdered 8 nurses in a Chicago dormitory.  At his trial, his lawyer claimed that he was innocent due to uncontrollable urges caused by his XYY genotype.  This novel appeal was akin to claiming insanity or severely diminished mental competence.  The jury was not convinced and found him guilty of murder.  He was sentenced to life in prison where he eventually died.  In fact, Richard Speck did not have an XYY genotype.  However, some researchers suggest that the high testosterone levels of XYY men can make them somewhat more prone to violence and that this may cause higher rates of wife beating.

Chromosomes are the structures that carry genes which in turn transmit hereditary characteristics from parents to offspring. Humans have 23 pairs of chromosomes, one half of each pair inherited from each parent. The Y chromosome is small, carries few genes, and has abundant repetitive sequence, while the X chromosome is more autosome-like in form and content.

Intersex is defined as a congenital anomaly of the reproductive and sexual system. An estimate about the birth prevalence of intersex is difficult to make because there are no concrete parameters to the definition of intersex. The Intersex Initiative, a North-American based organization, estimates that one in 2,000 children, or five children per day in the United States, are born visibly intersex. (36) This estimate sits within range; from genital anomalies, such as hypospadias, with a birth prevalence of around 1:300 to complex genital anomalies in which sex assignment is difficult, with a birth prevalence of about 1:4500. (37) Many intersex children have undergone medical intervention for health reasons as well as for sociological and ideological reasons. An important consideration with respect to sex assignment is the ethics of surgically altering the genitalia of intersex children to “normalize” them.
