title: PCR analysis of Yq microdeletions in infertile males, a study from South India.
abstract: OBJECTIVE
  To estimate the frequency of microdeletions in the long arm of Y-chromosome of 20 infertile males from South India.
  
  
  METHODS
  Polymerase chain reaction (PCR) amplification using Y-specific STS of azoospermia factor (AZF) regions i.e., SY 84 for AZFa, SY 127 for AZFb and SY 254 for AZFc.
  
  
  RESULTS
  Of the 20 infertile subjects 3 (15 %), one azoospermic and two oligozoospermic, showed microdeletions in the AZF region of Y-chromosome.
  
  
  CONCLUSIONS
  The frequency of deletions involving AZF region of the Y-chromosome is 15 % in azoospermic and severely oligozoospermic infertile men. PCR amplification of AZF locus is useful for the diagnosis of microdeletions in the Y-chromosome.
