In patients with non-obstructive azoospermia, testicular sperm extraction (TESE) is a method of choice to recover spermatozoa as a male therapeutic approach in intracytoplasmic sperm injection (ICSI) programmes. However, the efficacy of TESE in this indication is burdened by a frequent failure of sperm recovery, which renders useless both the invasive testicular intervention and ovarian stimulation of the patient's spouse. One of the most frequent pathological pictures characterizing complete absence of spermatozoa is germinal aplasia (Sertoli cell- only syndrome or SCOS). Two different histological patterns of SCOS have been already described during the past five decades. These two patterns can be characterized as the congenital (pure) and the secondary (mixed) forms. Both patterns, with different prognosis to retrieve spermatozoa by therapeutic testicular biopsy, are frequently confused when TESE is performed during ICSI programmes. Useful criteria to predict the absence of spermatozoa can be obtained by a definite recognition of the two typical histological patterns during the diagnostic testicular biopsy. The diagnosis of congenital or acquired SCOS can be refined by endocrine, chemical, immunohistochemical and molecular biology aids. Reduction of both sperm retrieval failure and unnecessary ovarian stimulation can be achieved by combination of these methods.
