Genetic screening for AZF Y chromosome microdeletions in Jordanian azoospermic infertile men

[摘要] The azoospermia factor (AZF) region of the human Y chromosome contains essential genes for spermatogenesis. Microdeletions in AZF region has been shown to cause male infertility. The aim of this investigation was to determine the frequency of AZF microdeletions in Jordanian infertile males. A sample of 100 infertile males (36 with azoospermia and 64 with oligozoospermia) was screened for microdeletions using 16 AZF markers and polymerase chain reaction (PCR) technique. Two subjects were found to have microdeletions in AZFc region and one subject has microdeletion that includes AZFb and part of AZFc and AZFa. The three deletions were found in azoospermic subjects (8.3%). No microdeletions were found in oligozoospermic group. The frequency of AZF microdeletions in Jordanian azoospermic infertile males is comparable to that observed in other populations (1%-15%). The results suggest the importance of AZF microdeletion analysis for genetic counseling prior to providing assisted reproduction technique.
