Molecular Study of Partial Deletions of AZFc Region of the Y Chromosome in Infertile Men
Background & Aims: The most significant cause of infertility in men is the genetic deletion in the azoospermia factor (AZF) region that is caused by the process of intra- and inter-chromosomal homologous recombination in amplicons. Homologous recombination could also result in partial deletions in AZF region. The aim of this research was to determine the association between the partial AZFc del...
متن کاملThe role of Y chromosome deletions in male infertility.
Male infertility affects approximately 2-7% of couples around the world. Over one in ten men who seek help at infertility clinics are diagnosed as severely oligospermic or azoospermic. Recent extensive molecular studies have revealed that deletions in the azoospermia factor region of the long arm of the Y chromosome are associated with severe spermatogenic impairment (absent or severely reduced...
متن کاملY chromosome deletions in azoospermic men in India.
Genetic factors cause about 10% of male infertility. Azoospermia factors (AZFa, AZFb, AZFc) are considered to be the most important for spermatogenesis. We therefore made an attempt to evaluate the genetic cause of azoospermia, Y chromosome deletion in particular, in Indian men. We have analyzed a total of 570 men, including 340 azoospermic men and 230 normal control subjects. DNA samples were ...
متن کاملPrevalence of Y chromosome deletions in a Brazilian population of nonobstructive azoospermic and severely oligozoospermic men.
We determined the prevalence of Y chromosome deletions in a population of 60 Brazilian nonobstructive azoospermic and severely oligozoospermic men. PCR-based screening of microdeletions was performed on lymphocyte DNA for the presence of 14 sequence-tagged sites (STS) located in the azoospermic factor (AZF) on the Yq chromosome. All STS were amplified efficiently in samples from 12 fertile men ...
متن کاملSUBMICROSCOPIC DELETIONS OF THE Y CHROMOSOME ARE NOT LIMITED TO AZOOSPERMIC MEN, BUT ARE ALSO DETECTED IN INFERTILE MEN WITH IDIOPATHIC OLIGOZOOSPERMIA
It is now agreed that 10-25% of infertile men with azoospermia have submicroscopic deletions of the Y chromosome long ann (yq), consistent with the proposed location of the azoospermia locus (AZF) in Yq 11.23. However, it is not known whether Yq microdeletions are unique to men with azoospermia or whether they are also observed in infertile men with less severe defects of spermatogenesis (o...
