Testing/or AZF micro-deletions by RT-PCR
It's Rapid, Sensitive and Specific test
In infertile couples, male factors account for almost half of the cases of infertility [1].
A constitutional chromosomal abnormality can be found in about 15% of azoospermic men and in 6%
of men with oligozoospermia.
With the advent of testing for Y chromosome microdeletions, about 7% of those patients previously
designated "idiopathic"now have a defined cause [2}.
AZF micro-deletion was identified in infertile men with azoospermia or very lowsperm concentrations
in the ejaculate [3,4].Evaluations of Y chromosome microdeletions in infertile men with NOA (Nonobstructive azoospermia) and severe OATS ( Oligoathenoteratospermia) should be
Performed before undertaking assisted reproductive techniques, such as multiple TESE (Testicular
sperm extraction) and ICSI ( Intracytoplasmic sperm injection [2]
The test detect microdeletions in the AZFa locus (sY86, sY84 & sY615), AZFb locus (sY127, sY134
and sY142) and AZFc locus (sY1197, sY254, sY255, sY1291, sY1125, sY1206, sY242) and
AZF( azoospermiafactor).
