[Predictive factors for successful sperm recovery in azoospermia patients]
1Department of Reproduction, Fisrt Hospital, Wenzhou Medical College, Wenzhou 325003, China.
Objective:
To find any predictive factors for successful testicular sperm recovery in azoospermic patients.
Methods:
50 cases of azoospermia were subjected to testicular biopsy. Serum follicle stimulating hormone (FSH), concentration, testicular volume, testicular histopathology, and testicular sperm extraction (TESE) were determined in each cases.
Results:
Neither serum FSH values nor testicular volume were predictive of spermatozoa in TESE. Testicular histopathology was specific for predicting successful sperm recovery (sensitivity 96%; specificity 100%; accuracy 100%).
Conclusions:
Azoospermia patients with high FSH and small testis should be recommended for testicular biopsy and TESE to confirm if there is any testicular spermatozoa.
