Abstract

Objectives: Microdissection testicular sperm extraction (micro-TESE) is an optimal technique of sperm extraction for intracytoplasmic sperm injection. This study is to present our experience in micro-TESE and evaluate the relation of its sperm retrieval rate (SRR) with patients' characteristics, testicular functions, and histological parameters as well as previous sperm retrieval interventions.

Materials and methods: We retrospectively reviewed records of 255 patients with nonobstructive azoospermia who underwent micro-TESE between 2011 and 2014. Medical records were reviewed for the results of follicle stimulating hormone (FSH), luteinizing hormone (LH), total testosterone levels, karyotype analysis, and testicular histology pattern. Testicular volume was measured with an ultrasound scale.

Results: The mean patients' age was 35.8 ± 7.2 years, duration of infertility 7.7 ± 4.5 years, right testicular volume 13.1 ± 5 ml, and left testicular volume 12.9 ± 5 ml. The overall SRR was 43.9%. SRR was significantly higher in testes with hypospermatogenesis histology pattern (P = 0.011). Patients' age, testicular size, serum FSH, LH, prolactin, and testosterone or failed previous sperm retrieval interventions showed no significant impact on SRR. Eleven (4.3%) patients had nonmosaic Klinefelter syndrome with a mean age of 37.8 ± 3.3 years. Sperms were retrieved in 6 (54.5%) patients. Post micro-TESE androgens significantly deteriorated with near complete recovery after 1 year.

Conclusions: Micro-TESE has a high SRR, minimal postoperative complications, and reversible long-term androgen deficiency. Sperm retrieval depends on the most advanced pattern of testicular histology. Hypospermatogenesis pattern has the highest SRR. We demonstrated a high SRR with micro-ESE in men with Klinefelter syndrome.
