Abstract
Background/aim:
Infertility is a main health issue. The human Y chromosome contains essential genes for spermatogenesis, especially
those located on four major intervals defined as AZFa, AZFb, AZFc, and AZFd. A partial deletion of the AZFc region is reported as a
significant risk factor for oligo-/azoospermia. The main purpose of this study was to investigate the prevalence of partial deletions in the
AZFc region (gr/gr, b1/b3, and b2/b3) in Iranian oligozoospermic candidates for intracytoplasmic sperm injection.
Materials and methods:
Multiplex PCR was used to assess the micro and partial deletions in 60 oligozoospermia infertile and 80 fertile
men.
Results:
Two cases (3.33%) showed AZFb deletion but no microdeletion was detected in the control samples. In the AZFc region, 20%
of the patients showed deletions, in which 15% and 5% showed gr/gr and b2/b3 deletions, respectively. However, 10% of the healthy
individuals also showed partial deletions, including gr/gr (7.5%) and b2/b3 (2.5%). No significant correlation was detected between the
presence of gr/gr microdeletion in patients and controls (P > 0.05).
Conclusion:
Our study showed that the partial AZFc deletions are not associated with male infertility in Iranian subjects.
