Abstract
Defined infertility as incapability of a married couple tᴏ have children for the
one-year ᴏf unprotected intercourse. Y chromosomal microdeletions are the
second greatest common genetic reason of men sterility. This research aims to
find the prevalence of AZF Y chromosome microdeletions in azoospermic and
severe oligospermia patients. Further, to evaluate the prevalence types of
AZF/c sub-region microdeletions in patients with AZF/c deletion in Iraq. A
total of 75 infertile Iraqi males and 25 control were included in this study. The
DNA samples were extracted, and they were analysed for AZF microdeletions
by utilizing eight sequence-tagged sites through a q/real-time PCR system.
After that, partial AZF/c deletion sub-region was investigated using four
specific primers. These markers were chosen according to the EAA/ EMGQ
recommendations. Out of 75 infertile patients, 46 patients (61.33%) revealed
AZF microdeletions in the Y chromosomal with at least one STS deletion for
one or more AZF regions. (32.6%) of patients with microdeletions observed in
three regions AZFabc. Out of 24 patients who have AZF/c microdeletions
(37.5%) were exhibited b2/b4 deletion (complete AZF/c deletions), (58.3%)
were showed gr/gr microdeletion (partial AZF/c deletions. and (4.1%) with
b2/b4 deletion continues the terminal heterochromatin region. The incidence
of classical AZF microdeletions in our study subjects is high. In our study
population, gr/gr partial AZF/c microdeletions were higher than b2/b4
complete AZF/c deletion. The mean levels of sex hormones in azoospermic
sterile patients with AZF microdeletion were higher than the mean of
azoospermic sterile men without deletion of AZF.
