Abstract

Purpose: Klinefelter Syndrome (KS; 47, XXY) and Y chromosome microdeletions are the most common genetic

causes of male infertility. Our goal was to assess these factors contributing to male infertility in our region.

Material and Methods: In this current study, 58 patients diagnosed with azoospermia/oligozoospermia were invited

to the polyclinic and 2 ml peripheral blood samples were collected. Genotyping by employing PCR based-fragment

analysis was conducted after isolating genomic DNA from the peripheral blood samples of patients who consented to

participate in our study. Patients' FSH, LH, and testosterone levels, as well as their physical examinations, were

carefully evaluated.

Results: We found that high follicle stimulating hormone (FSH) value can be used as a predictive factor in

azoospermia. We successfully revealed the potential of KS (3.2%) but no Y chromosome microdeletions are

responsible for primary male infertility. A patient with KS was identified, exhibiting not only short stature but also a lack

of breast enlargement.

Conclusion: Non-genetic factors such as varicocele (28%) and smoking (28%) may have greater potential to explain

primary infertility in our region. Physicians should be aware that unexpected features such as short stature may

accompany KS in adult patients who have not received growth hormone treatment.
