Abstract
Abstract
Objectives
Chromosome anomalies and Y chromosome microdeletions are one of the reasons that can be seen in infertile patients and affect fertility. In this study, it was aimed to determine the frequencies of chromosomal anomalies and Y chromosome microdeletions in primary infertile male patients.
Methods
We included 374 patients with primary infertility in this study. Cytogenetic analysis was performed with the GTG banding technique by using trypsin and Giemsa stain. Y microdeletion analysis was studied by multiplex polymerase chain reaction using 28 Y chromosome-specific sequence-tagged sites.
Results
Chromosomal irregularities were detected in 27 (7.22%) of infertile cases. It was observed that 7 (25.92%) of chromosomal irregularities detected in cases were in autosomal and 20 (%74.08) were in gonosomal chromosomes. The incidence of Y chromosome microdeletion was 1.07% (4/374) and the microdeletions were observed in AZFb, AZFc and AZFd regions. AZFc + AZFd deletion was detected in three patients (0.81%) and AZFb + AZFc + AZFd deletion in one patient (0.26%).
Conclusions
In conclusion, gonosomal chromosome irregularity was higher than autosomal chromosome irregularity in infertile men. The frequency of Y microdeletion has different rates according to some factors such as ethnic differences of patients, patient selection criteria, differences in the number of cases, and methodological aspects.
