Özet

Objective: To determine the frequency, types of chromosomal abnormalities and Y chromosome microdeletions in patients with severe male factor infertility, and the association between clinical background and genetic abnormality. Study design: A total of 322 infertile men; 136 men with severe oligozoospermia (sperm count <5 million/ml) and 196 with nonobstructive azoospermia were studied between April 2004 and November 2006 at the Dr. Zekai Tahir Burak Women's Health Education and Research Hospital, Ankara, Turkey. Blood, semen samples, and testicular biopsies of patients were obtained. Hormonal analysis (follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels), semen analysis, karyotype analysis, and PCR screening for Y chromosome microdeletions were performed. Result(s): Forty-eight out of 332 (14%) infertile men had a genetic abnormality. Twenty-four (7.2%) cases with karyotype abnormality were detected. The frequencies of karyotype abnormalities were Klinefelter's syndrome 17/24 (71%), translocation 3/24 (12%), mix gonadal dysgenesis 2/24 (8%), XX male 1/24 (4%), and 46XYY 1/24 (4%). Twenty cases (6%) infertile men had only Y chromosome microdeletions. The frequencies of the deleted areas were azoospermia factor (AZF) c 42%, AZFb 25%, AZFa 21%, AZFb, c 8%, and AZFa, c 4%. Four of the cases with Y chromosome microdeletions also had a concurrent karyotype abnormality. Conclusion(s): All patients with nonobstructive azoospermia and severe oligozoospermia (sperm count <5 million/ml) should undergo genetic screening.
