Aim: To determine the frequency of genetic deletions within the azoospermia factors in Egyptian infertile males. Methods: The Yq microdeletions in 33 infertile males with undetectable chromosomal anomalies were examined by mutiplex polymerase chain reaction (PCR). Deletions were confirmed using single PCR amplifications. Results: Four out of the total 33 (12 %) men had Yq11 microdeletions, thus supporting the average reported figures in other populations. Three of those 4 cases had single short tandem sequence deletions with discrete histological findings of their testes. Single sY272 deletion within AZFc was associated with Sertoli cell only syndrome, whereas a patient with isolated sY84 deletion within AZFa had immature testicular structure. The remaining case had a large deletion in AZFa-c and short stature. Conclusion: The present study supports the hypothesis that the Yq11 encompasses genetic determinants of stature besides genes controlling spermatogenesis.
