XYY syndrome prevention?

Question

can tell me how to prevent the XYY syndrome? I really need it for my biology class.

your help is well appreciated! :-)

Answer 1

well prenatal vitamins help with genetic anomalies.

so does eating well, staying away from chemicals, exercising lightly.

it is a random happening, they're not sure exactly why it happens.

Answer 2

Well, there isn't much you can do to prevent it. It is completely by chance. Sperm is made in such massive amounts that a lot of it isn't good (think about how shoddy mass-produced merchandise is), but the trek that it needs to take from the birth canal to the fallopian tube to fertilize the egg usually weeds out those that are 'bad.'

But, there is always a chance. The only real thing that can be done to prevent it is for the father to be younger when he is siring children. The older a father gets, the more likely his gametes are to make a mistake when producing sperm. But it doesn't completely eliminate the chances for a younger guy to have a child with XXY syndrome, it just isn't as common.

There are also vitamins that can be taken by men to ensure their sperm is of better quality. How effective they are, I do not know. Still, it probably isn't a bad idea to look into it.

Answer 3

It can't be prevented. It's a gene disorder in which the sperm accidentally carries two copies of the Y chromosome due to nondisjunction and forms a fetus with an egg. The only way it could be "prevented" is to individually screen each sperm, which is impossible.

Answer 4

Have children when you are in your twenties.  Chromosomal defects are significantly lower at younger ages.

You should be able to find a table or graph that actually correlates the mother's/father's age with various health criteria of a baby.

IVF screening is actually an option too.  This already occurs.

Answer 5

XYY s*x chromosome trisomy or XYY Syndrome, also known as Jacob Syndrome, was once called Super Male Syndrome, in that it was thought to cause increased testosterone levels, and increased aggressive, antisocial and criminal behavior, primarily because of one case, Richard Speck, the mass murderer of several nursing students in Chicago, who was discovered to have an XYY karyotype.  More recent research supports the view that XYY males do not differ significantly from other males behaviorally or biologically, as evidenced by the fact that about 85% of XYY individuals and their physicians are unaware of their chromosomal abnormality.

Nevertheless, if the goal is to reduce XYY incidence, then the same approach applies as with most chromosomal abnormalities, such as Trisomy 21 (Down's Syndrome), and that is to:

(1) perform prenatal testing, such as AMNIOCENTESIS, to make sure that your baby will not be born with a chromosomal defect;

(2) procreate at earlier ages, since chromosomal abnormalities correlate positively with parental age;

(3) minimize exposure to ionizing radiation, especially X-rays and ultraviolet rays (i.e., overexposure to sunlight or tanning lamps); and

(4) avoid ingestion of mutagenic, teratogenic, and carcinogenic chemicals, such as acrylonitrates, aniline, anesthetic gases, arsenic compounds, benzene, benzopyrene, beryllium, boron (boric acid), cadmium, carbon monoxide, chlordicone, chloroform, chloroprene, dichloromethane, epichlorohydrin, ethylene oxide, formaldehyde (formalin), hexachlorobenzene, lead, methyl ethyl ketone, monomethylformamide, nitrogen dioxide, ozone, certain selenium isotopes, thallium, toluene, vinyl chloride, and xylene.
