TESTICULAR SPERM RETRIEVAL PROCEDURE: FINE NEEDLE ASPIRATION VERSUS OPEN BIOPSY
Abstract
Introduction. Opportunity to sperm in azospermic men is an essential component of successful intracytoplasmic sperm injection. This study evaluate the efficacy of fine needle biopsy (FNA) versus open biopsy for spermatozoid retrival in azospermic men.
Methods. Fine needle biopsy was performed in 1030 azospermic men for sperm retrival. Testicular open biopsy was performed in any cases with no obtained sperm in FNA. About 50 percent of patients have normal FSH level and other ones have high FSH lenvel.
Results. FNA had a success rate about 29 percent for sperm retrival in azospermic patients. In patients with FNA failure, open biopsy could retrieve sperm in 21 percent cases. FNA and open biopsy with each other could retrieve sperm in 44 percent of azospermic patients.
Discussion. FNA may has a first role for sperm retrieval in azospermic patients, but use of open biopsy is necessary in patients with FNA failure.
