Detection of Y Chromosome Microdeletions and Hormonal Profile Analysis of Infertile Men undergoing Assisted Reproductive Technologies
Objective Y chromosome deletions (YCDs) in azoospermia factor (AZF) region are associated with abnormal spermatogenesis and may lead to azoospermia or severe oligozoospermia. Assisted reproductive technologies (ART) by intracytoplasmic sperm injection (ICSI) and testicular sperm extraction (TESE) are commonly required for infertility management of patients carrying YCDs. The aim of this study w...
متن کامل[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 کاملPartial and complete microdeletions of Y chromosome in infertile males from South of Iran
Y chromosome microdeletions are the second genetic cause of male infertility. The incidence of Y chromosome microdeletions can vary considerably depending on several factors, including patient selection criteria, population composition, and diagnostic protocols. They are associated with spermatogenic failure and lead to azoospermia or oligozoospermia. The advance in assisted reproductive techno...
متن کاملFrequency of Y Chromosome Microdeletions in Azoospermic and Oligospermic Iranian Infertile Men
Background and Aims: Azoospermia factor (AZF) region of the Y-chromosome has several genes which are responsible for normal spermatogenesis. Microdeletions of these genes are associated with azoospermia and oligospermia. These microdeletions are too small to be detected by karyotyping. They can be easily identified using polymerase chain reaction. The aim of this study is to determine the frequ...
متن کاملY chromosome microdeletions frequency in idiopathic azoospermia, oligoasthenozoospermia, and oligospermia
Background Genetic factors are candidates for about 30% of male infertility with sperm production-related abnormalities. Y chromosome microdeletions are responsible for around 10% of male infertility. These microdeletions generally occur in azoospermia factor on the Yq. That is often associated with the quantitative reduction of sperm. Objective The aim of this cross-sectional study was to de...
