Effects of Testicular Volume, Follicle Stimulating Hormone, Luteinizing Hormone and Presence of Varicocele On Successful Sperm Retrieval In Non-Obstructive Azoospermia

The aim of the study was to evaluate the relation between the probability of positive sperm extraction with Testicular Sperm Extraction (TESE) and the clinical, laboratory and demographic features in a series of non-obstructive azoospermia (NOA) infertility patients who consulted to Urology Department in order to determine and inform couples who could not succeed and thus avoid unnecessary treatment. Sixty-four patients with non-obstructive azoospermia were enrolled to the study. Demographical features and previous varicocele operation history were noted. In all cases serum levels of Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), genetic analysis and bilateral testicular volume were determined to find the correlation between probability of positive sperm extraction with TESE. The incidence of NOA among all infertile men was 15.1%. TESE success rate in NOA was 29,6%. There were significant differences in FSH levels (p
