Extra sex chromosome causing infertility

For Double Y syndrome men, the reproductive outlook varies; the extra Y chromosome is often lost during the early spermatogonial stages and this generates. Aug 17, - Since , we have known that an extra X chromosome in men (XXY instead of XY, also known as Klinefelter's syndrome) is associated with low sperm production and infertility. This is now recognised as the most common genetic cause of infertility. Klinefelter syndrome, 47,XXY, or XXY syndrome is a condition where human males have an extra X chromosome. Males normally have a chromosomal makeup of XY, but an affected individual with Klinefelter syndrome will have at least two X chromosomes and at least one Y chromosome.‎Klinefelter's Syndrome · ‎Genetics · ‎Diagnosis · ‎Turner's Syndrome.

  1. These include the lack of homology between the X and Y chromosomes in the male germline in which autosomal homologs must pair and the imbalance in X-linked gene dosage between males and females.

  2. In the female germline, the inactive X chromosome is reactivated before meiosis. We also studied aneuploidy rates of the sex chromosomes and autosomes in this patient's sperm to determine the relationship between XYY germ cells and the chromosomal constitution of the resulting sperm.

  3. Y chromosome deletions What are Y chromosome deletions? New study reveals the function of a mysterious component of the inner ear June 28, A few years ago, Ian Swinburne, HMS research fellow in systems biology, noticed something odd while conducting a time-lapse microscopy study of the inner ear of zebrafish. At that time, hormone levels were normal.

  4. Genes in these regions are believed to provide instructions for making proteins involved in sperm cell development, although the specific functions of these proteins are not well understood. The research is really quite remarkable.

  5. Cell coordinates were recorded for subsequent analyses of the sex chromosomes identified by FISH. People with this condition have an extra copy of chromosome 21 and have a range of disabilities. There are no surgical treatments for CAVD but it is usually possible to collect sperm directly from the testis or epididymis that can be used in assisted reproduction treatments such as ICSI when a man wishes to have a child.
