The impact of Turner syndrome on women

Turner syndrome is a chromosomal condition caused by partial or total loss of one of the X chromosomes.
All human beings have 23 pairs of chromosomes and this is what is known as the karyotype. It is where all genetic information is stored. In other words, it is what determines our external appearance, our personal physical characteristics, how our organs work, whether or not we will have certain illnesses and so on. There are 22 pairs of numerical chromosomes ranging from 1 to 22 and one pair of sex chromosomes: X and Y. Women have two X chromosomes – one from their father and one from their mother. Men have one X chromosome – from their mother – and one Y chromosome – from their father. If, when a female embryo is generated, incorrect division leading to total or partial loss of the X chromosome takes place, this generates an abnormal karyotype that is characteristic of women with Turner syndrome. The syndrome, by definition, does not occur in males because they only have one X chromosome and cannot live unless this chromosome is present.

In contrast with the old-fashioned belief that reproduction issues are a female thing, current figures are clear: 47% of infertility cases in a couple are down to an issue with the man. Therefore, when a couple has infertility issues and they seek the help of a clinic specialising in assisted reproduction, the tests and analyses are carried out on both members of the couple. This practice of looking into both the female factor and the male factor is now common and carried out by all experts in the field, but there is still a lack of understanding of the fertility issues which men can have. What are they? What solutions do leading assisted reproduction clinics offer nowadays?
The most common issues amongst men are “changes in the sperm count with no apparent cause”, explains Instituto Bernabeu in Alicante. That is, a low number of sperm, poor sperm mobility or abnormal morphology. Additionally, there may be more concrete and identifiable reasons for changes in sperm such as obstruction issues, infection, diseases or genetic reasons which impede egg fertilisation or which affect embryo quality.
