Human Y chromosome azoospermia factors (AZF) mapped to different subregions in Yq11.

In a large collaborative screening project, 370 men with idiopathic azoospermia or severe oligozoospermia were analysed for deletions of 76 DNA loci in Yq11. In 12 individuals, we observed de novo microdeletions involving several DNA loci, while an additional patient had an inherited deletion. They were mapped to three different subregions in Yq11. One subregion coincides to the AZF region defi...

Human chromosome deletions in Yq11, AZF candidate genes and male infertility: history and update.

Human chromosome deletions in Yq11 seem to occur frequently as de novo mutation events in men with idiopathic azoospermia or severe oligozoospermia. However, the molecular extensions of these deletions are variable. They can be large and therefore visible under the microscope or small, not visible under the microscope, and containing the deletion of one or more DNA loci recently mapped in an ap...

Male Infertility: Screening of Azoospermia Factor (azf) Microdeletion in Idiopathic Infertile Men

Genetic factors cause about 15% of male infertility and microdeletions of Y chromosome is one of the genetic causes in idiopathic infertile men. Azoospermia factors (AZFa, AZFb, and AZFc) on Yq long arm are most important for spermatogenesis. For analysis of microdeletions in the AZF regions by sequence-tagged-site (STS) PCR is important screening method for infertility. An attempt has been mad...

I-6: Azoospermia Factor in Male Infertility

Background The human Y chromosome is essential for human sex determination and male germ cell development and maintenance. In 1996, Vogt et al. identified three recurrently deleted regions in Yq11 termed the azoospermia factor (AZF). The AZF region is subdivided into three non-overlapping sub-regions called AZFa, AZFb and AZFc and microdeletion in these regions is the most important etiology of...
