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...
متن کاملMale 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...
متن کاملY chromosome azoospermia factor region microdeletions and transmission characteristics in azoospermic and severe oligozoospermic patients.
Spermatogenesis is an essential reproductive process that is regulated by many Y chromosome specific genes. Most of these genes are located in a specific region known as the azoospermia factor region (AZF) in the long arm of the human Y chromosome. AZF microdeletions are recognized as the most frequent structural chromosomal abnormalities and are the major cause of male infertility. Assisted re...
متن کاملSomatic cytogenetic and azoospermia factor gene microdeletion studies in infertile men.
The objective of the present study was to determine the frequency of somatic chromosomal anomalies and Y chromosomal microdeletions (azoospermia factor genes, AZF) in infertile males who seek assisted reproduction. These studies are very important because the assisted reproduction techniques (mainly intracytoplasmic sperm injection) bypass the natural selection process and some classical chromo...
متن کاملبررسی مولکولی حذف‌های کروموزوم Y در نواحی AZF بیماران مبتلا به آزواسپرمی و اولیگواسپرمی غیر انسدادی مراجعه‌کننده به مرکز ناباروری منتصریه مشهد
Background and Aim: The Y-chromosome azoospermic factor (AZF) regions consist of genes whose specific roles and functions in spermatogenesis and fertility have not been completely clarified. Hence, recognition of the association between AZF microdeletions and male infertility has suggestions for the diagnosis, treatment, and genetic counseling. The main objective of the present study was invest...
