[Real-time fluorescent PCR for screening AZFc/DAZ microdeletions on the Y chromosome in male infertility patients].
OBJECTIVE
To develop a real-time fluorescent PCR protocol suitable for the routine screening of AZFc/DAZ microdeletions on the Y chromosome in azoospermic and oligozoospermic male infertility patients.


METHODS
A set of real-time fluorescent PCR was established. Eighty-seven azoospermic and ligozoospermic patients undergoing ICSI in the IVF center and 30 azoospermic men undergoing testicular biopsy in the clinic of urology surgery were screened for AZFc/DAZ microdeletions of Y chromosome.


RESULTS
Eleven cases (9.4%) of AZFc/DAZ microdeletions were found in 117 cases of azoospermic and oligozoospermic patients by screening of realtime fluorescent PCR. Four cases (6.6%) were found in 61 oligozoospermic patients, and 7 cases (12.5%) were found in 56 azoospermic patients.


CONCLUSIONS
The real-time fluorescent PCR protocol presented in this study is an easy and reliable method for detection of AZFc/DAZ microdeletions on the Y chromosome, which yields identical results to those of the multiplex PCR.
