Intersex is a term applied to people whose biological sex cannot be classed as clearly male or female.
- "An intersex person may have the biological attributes of both sexes or lack some of the biological attributes considered necessary to be defined as one or the other sex."[1]
Intersex conditions
There are various types of intersex condition, with different causes, including:
- Klinefelter syndrome (see below)
- androgen insensitivity syndrome (AIS) in which the person has a Y chromosome, but the androgens (male sex hormones) are not produced as normal.
Chromosome differences
The nucleus of a human cell usually contains 46 chromosomes, comrpising 22 pairs of autosomes, plus two allosomes (sex chromosomes). The two allosomes are usually X and Y for a man, or X and X for a woman. Some other combinations are:
- 45,X – a female with one X chromosome missing, also known as Turner syndrome
- 47,XYY – a male with an extra Y chromosome
- 47,XXY – a male with an extra X chromosome, also known as Klinefelter syndrome
- 47,XXX – a female with an extra X chromosome
