BACKGROUND It has been hypothesized that Y-q microdeletion can account for significant proportion of infertility in men. There are three nonoverlapping regions referred to as the "azoozpermia factors" AZFa, AZFb, and AZFc from proximal to distal part of Y-q. These have been defined as spermatogenesis loci, this region deletions have been shown to be involved in male azoospermic or severe oligoo...

Due to its palindromic setup, AZFc (Azoospermia Factor c) region of chromosome Y is one of the most unstable regions of the human genome. It contains eight gene families expressed mainly in the testes. Several types of rearrangement resulting in changes in the cumulative copy number of the gene families were reported to be associated with diseases such as male infertility and testicular germ ce...

BACKGROUND To review the possible mechanisms proposed to explain the etiology of 46, XX sex reversal by investigating the clinical characteristics and their relationships with chromosomal karyotype and the SRY(sex-determining region Y)gene. METHODS Five untreated 46, XX patients with SRY-positive were referred for infertility. Clinical data were collected, and Karyotype analysis of G-banding ...

objective: microdeletions of the y chromosome long arm are the most common molecular genetic causes of severe infertility in men. they affect three regions including azoospermia factors (azfa, azfb and azfc), which contain various genes involved in spermatogenesis. the aim of the present study was to reveal the patterns of y chromosome microdeletions in iranian infertile men referred to royan i...

background: the aim of this study was to determine the incidence of azf (azoospermia factor) microdeletions of the y chromosome in infertile turkish male patients and intracytoplasmic sperm injection (icsi) outcome of these patients. objective: this study was undertaken in order to evaluate the outcome of intracytoplasmic sperm injection (icsi) in infertil man with azf microdeletions materials ...
