Turner Essay, Research Paper
Turner’s Syndrome
A relatively uncommon human sex-chromosome disorder. Males very rarely
contract this disease. Its occurrence rate in females is about one per
3,000 live female births.
Occurs when a sperm carrying no sex chromosomes fertilizes a normal ovum,
resulting in a female that has only one X chromosome, producing a male
body type: short, with a broad neck, and usually lacking female internal
reproductive organs and secondary sex characteristics. The patient is
usually sterile and pregnancy is rare. Other signs and symptoms include a
low hairline, webbed neck, shield-shaped chest with widely spaced nipples,
and usually kidney and heart malformations. The patient may also have
immature breasts and be of above-average height. Some are mildly
retarded.
Despite many efforts, no real causes have been found to be linked to this
condition. It appears be a random event that can happen to anyone.
There is no reason why a woman with Turner s Syndrome should not
lead a full, productive life. It is important though that she get good
medical care regularly.
