High prevalence of testicular cancer in azoospermic men without spermatogenesis.

BACKGROUND An increased risk of testicular cancer in men with infertility and poor semen quality has been reported. Our aim was to investigate the prevalence of testicular nodules and cancer in azoospermic subjects with different spermatogenetic patterns. METHODS A total of 1443 consecutive infertile men were investigated, out of which 145 (10.0%) were found to be azoospermic. By using clinic...

Chromosomal Aneuploidy in Azoospermic Men

The aim of this study was to estimate the prevalence of chromosome abnormalities in patients with azoospermia, in our material. Preoperative evaluation included routine andrological investigations with 2 semen analysis, ultrasound, hormonal and genetic examinations. In the last three years, 73 biopsies were performed for testicular sperm extraction in 71 patients. Non-obstructive azoospermia wa...
