[Y chromosome microdeletions in male infertility].
A genetic basis of infertility may exist in many men currently classified as having idiopathic infertility. Approximately 7% of infertile men harbour submicroscopic deletions of the Y chromosome that are not detectable on routine karyotype. Two candidate gene families, namely the RNA-binding motif-containing gene family, and the deleted-in-azoospermia gene family, have been cloned by deletion m...
متن کاملY chromosome and male infertility.
Recent genome analysis of the Y chromosome has increased the number of genes found on this chromosome markedly. Many of these genes in the part of the Y chromosome that does not undergo recombination with the X chromosome are members of gene families. Evolutionary considerations imply that genes on the Y chromosome will degenerate unless they have male advantageous or female deleterious functio...
متن کاملMicrodeletions on the long arm of the Y chromosome and their association with male-factor infertility.
Significant advances in treatment have enabled previously infertile males to achieve fatherhood, when only a few years ago they would have had no chance of biological paternity. In contrast to the overall success of assisted reproduction, the aetiology of male-factor infertility is poorly understood. Recent studies have shown, however, that a significant proportion of men with severe infertilit...
متن کاملGenetic markers of male infertility: Y chromosome microdeletions and cystic fibrosis transmembrane conductance gene mutations.
Today, approximately 15% of couples have reduced fertility. In most cases the reason is male infertility, usually of genetic origin. Thus, in the context of research in genes involved in reproduction and sex determination, genetic defects in gametogenesis are being extensively studied. The most frequent pathogenic causes of male infertility are Y chromosomal microdeletions and obstructive azoos...
متن کاملDetection of Y chromosome microdeletions and mitochondrial DNA mutations in male infertility patients.
Infertility affects about 10-15% of all couples attempting pregnancy with infertility attributed to the male partner in approximately half of the cases. Proposed causes of male infertility include sperm motility disturbances, Y chromosome microdeletions, chromosomal abnormalities, single gene mutations, and sperm mitochondrial DNA (mtDNA) rearrangements. To investigate the etiology of decr...
