Is XXY chromosome a male?
Females have two X sex chromosomes (XX). Males have an X and a Y sex chromosome (XY). Klinefelter syndrome can be caused by: One extra copy of the X chromosome in each cell (XXY), the most common cause.
What is the meaning of XXY?
Klinefelter syndrome is a genetic condition in which a boy is born with an extra X chromosome. Instead of the typical XY chromosomes in men, they have XXY, so this condition is sometimes called XXY syndrome. Men with Klinefelter usually don’t know they have it until they run into problems trying to have a child.
CAN XXY people have children?
Most boys with Klinefelter syndrome can have sex when they become men, usually with the help of testosterone treatment. But problems with their testicles prevent them from making enough normal sperm to father children. Most men with the condition are infertile and can’t father a child the usual way.
Can Klinefelter have normal sperm count?
This is known as Klinefelter Syndrome and is the most common genetic variation which impacts a man’s fertility. Men with pure Klinefelter Syndrome are nearly universally azoospermic with a sperm count of zero in the semen due to a lack of adequate sperm production in the testicles.
What does it mean to have an XXY chromosome pattern?
In particular, someone born with an xxy chromosomal pattern does not fall into standard biological paradigms of sex in which male is xy while a female is xx. Were biology/chemistry alone the answer, then we’d have a subset of humanity unable to truly fulfill their sexual capacity (xxy).
What is the difference between male and female chromosomes?
A person’s biological sex is determined by the sex chromosomes: females have two X chromosomes, or XX; most males have one X chromosome and one Y chromosome, or XY. Males with XXY syndrome are born with cells that have an extra X chromosome, or XXY.
What is a chromosome?
A chromosome is a strand of DNA. XXY chromosomes are a naturally occurring human male variation. XXY men are identical in physical appearance and mental capacity to XY men. XXY Quick Facts: • XXY = male. • One in every 500 male births is XXY. • Numerous studies show XXY boys and men possess the same capabilities as XY boys and men.
Do chromosomes tell the whole story?
This means somewhat controversially that whether we have an xy, xx, or xxy chromosome pattern, these biological and chemical compositions do not tell the whole story. In particular, someone born with an xxy chromosomal pattern does not fall into standard biological paradigms of sex in which male is xy while a female is xx.
