Genetic disorders

These are uncommon but do occur in men who have low or no sperms. Some of these are not immediately obvious but there is concern over one particular type of gene which causes problems with the Y-chromosome. This can be passed down to male offspring as a result of an assisted fertility technique such as intracytoplasmic sperm injection (ICSI). And this can lead to infertility.

Another genetic disorder is Klinefelters syndrome which leads to an extra Y-chromosome in men. It is also known as ‘trisomy’ and is characterised as XYY rather than the usual male XY configuration.

It is easy to assume that men who have this extra chromosome will be extra fertile but unfortunately the opposite is true. They tend to have serious fertility problems and are often classed as being sterile.
