Azoospermic patients have the option of undergoing in vitro fertilization
procedures, specifically intracytoplasmic sperm injection (ICSI), for which
sperm is retrieved from the patient's own testicles and then injected directly
into the oocyte. The aim of the study: evaluate the role of repeated sperm
extraction by enzymatic and mechanical mincing techniques in azoospemic
patients. A total of 32 males with non-obstructive azoospermia participated in
the research. Testicular sperm extraction (TESE) was performed under spinal
or general anesthesia after a comprehensive history, physical examination,
and investigations. After that, the biopsies underwent through a series of
mincing processes, both mechanical and enzymatic. Patients gave information
including age, body mass index and previous biopsy attempts. In both
enzymatic and mechanical methods there was no significant higher sperm
recovery in patients with history of previous testicular biopsies (66.7% vs.
38.5%; p=0.209) and (66.7% vs. 30.8%; p=0.102) respectively. Patients who
had undergone prior testicular biopsies had marginally higher sperm recovery
rates using both enzymatic and mechanical techniques
