Background and Aims: Testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI) is an effective procedure for the treatment of male infertility, obstructive and non‐obstructive azoospermia. We have reviewed our experience to investigate the correlation of TESE‐ICSI with morphological, biophysical and endocrine profiles in 27 men. Results: Testicular spermatozoa could be retrieved in 25 of 27 patients who underwent TESE. In two cases, testicular spermatozoa could not be recovered and their serum follicle‐stimulating hormone (FSH) levels were significantly higher than those of the former group. However, spermatozoa could be retrieved in sufficient numbers for ICSI, even in the patient with the highest FSH concentration. Johnsen scores evaluated by diagnostic pre‐TESE open biopsies were significantly higher in the cases with viable testicular spermatozoa than those in the cases without spermatozoa. However, even in the patient whose Johnsen score was 2.1, testicular spermatozoa could be retrieved with TESE, and pregnancy was achieved by ICSI. Conclusions: The serum FSH levels and the histological findings of the testes were strong predictors for successful TESE and provided useful information for consultation and making treatment decisions on an individual case. However, whether a patient has enough spermatozoa so that an IVF procedure with ICSI is possible can only be answered by a trial TESE. (Reprod Med Biol 2003; 2 : 31–35)
