TESTICULAR SPERM EXTRACTION AND INTRACYTOPLASMIC SPERM INJECTION

1998

We evaluate the efficacy of testicular sperm extraction and results of intracytoplasmic sperm injection in cases of nonobstructive azoospermia. In addition, we define predictive parameters for successful testicular sperm extraction in these patients.A total of 154 patients with nonobstructive azoospermia underwent multiple testicular biopsies to obtain testicular spermatozoa and for histopathological diagnosis. Results of testicular sperm extraction were related to suspected etiology of azoospermia, patient age, maximal testicular volume, serum follicle-stimulating hormone and histopathology. When testicular sperm extraction was successful, intracytoplasmic sperm injection was performed.Spe…
