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
Intratesticular testosterone plays a crucial role in male reproductive function and overall health. Body Mass Index (BMI) and smoking are known lifestyle factors that can influence hormonal balances. Elevated BMI has been associated with alterations in testosterone levels, impacting male fertility and endocrine function. The aim was to examine the concurrent relationships between intratesticular testosterone, BMI, and smoking habits. Biopsies of the testicles were taken from 32 patients with non-obstructive azoospermia. Testicular sperm extraction (TESE) under spinal or general anesthesia was performed after a comprehensive history, physical examination, and investigations. After performing a minced biopsy and centrifuging the fluid, testicular fluid was extracted. The highest intratesticular testosterone levels were in normal patients and lowest levels in over weight patient; on the contrary the highest serum 17-hydroxyprogesterone levels were found in over weight patient and lowest levels in normal weight patients; There were insignificantly higher both intratesticular testosterone and 17-hydroxyprogesterone levels in non-smokers. In conclusion, the statistical analysis revealed that there is an insignificantly low correlation between intratesticular testosterone levels, BMI, and smoking.
