Sažetak
The aim of this study was to evaluate the predictive value of factors in infertile male patients to retrieve sperm from their testicles before they undergo testicular sperm extraction (TESE). In total, 64 males were enrolled in this study. Infertility was identified as obstructive azoospermia (OA) ; non-obstructive azoospermia (NOA) ; Klinefelter syndrome (KS) ; and cryptozoospermia (Crypt). Age, body mass index and concomitant conditions were noted. Testicular volumes, serum levels of Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), testosterone (T) and prolactin were investigated. Sperm retrieval after TESE was noted as positive or negative. Average age of the cases was 36.8 years. TESE success rate of testicular sperm retrieval rate was 50.0%. Majority of men (83.9%) had a 46, XY karyotype, minority had genetic anomalies, and 5 of were diagnosed with KS – all were TESE-negative. There was no statistical difference in age, testicular volume, presence of varicocele and microcalcifications or hormonal levels in the TESE-positive and negative groups. Smoking as an independent variable was the only risk factor statistically showing (OR = 0.269 ; p = 0.045) prediction of negative sperm retrieval after the TESE procedure. None of the parameters investigated herein predicted successful TESE outcomes. However, in cases with negative TESE only smoking was identified as a predictive factor for negative sperm retrieval and was established as a risk factor.
