Testicular sperm extraction (TESE) is the process of removing a small portion of tissue from the testicle under local anesthesia and extracting the few viable sperm cells present in that tissue for intracytoplasmic sperm injection (ICSI).[1] The testicular sperm extraction process is recommended to men who cannot produce sperm by ejaculation due to azoospermia, such as that caused by primary testicular failure, congenital absence of the vas deferens or non-reconstructed vasectomy.
Intracytoplasmic sperm injection (ICSI) and testicular sperm extraction (TESE) have reduced the need for donor sperm.
Serum inhibin-B weakly indicates presence of sperm cells in the testes, raising chances for successfully achieving pregnancy through TESE, although the association is not very substantial, having a sensitivity of 0.65 (95% confidence interval [CI]: 0.56–0.74) and a specificity of 0.83 (CI: 0.64–0.93) for prediction the presence of sperm in the testes in non-obstructive azoospermia.[2]
Seminal plasma proteins TEX101 and ECM1 were recently proposed for the differential diagnosis of azoospermia forms and subtypes, and for prediction of TESE outcome.[3]

- Azoospermia due to Spermatogenic Failure.

The causes and genetic contributions to spermatogenic failure are reviewed. Medical therapies including use of hormonal manipulation, whether guided by a specific abnormality or empiric, to induce spermatogenesis are discussed. The role of surgical therapy, including a discussion of varicocelectomy in men with spermatogenic failure, as well as an in-depth review of surgical sperm retrieval with testicular sperm extraction and microdissection testicular sperm extraction, is provided. Finally, future directions of treatment for men with spermatogenic failure are discussed, namely, stem cell and gene therapy.

- Should repeated TESE be performed following a failed TESE in men with Klinefelter Syndrome?
- Haliloglu AH, Tangal S, Gulpinar O, Onal K, Pabuccu R.Author information Department of Urology, Ufuk University School of Medicine, Ankara, Turkey.AbstractThe main goal of this study was to evaluate the success rate of repeated Testicular Sperm Extraction (TESE) in Klinefelter Syndrome (KS). Eighteen patients with the diagnosis of KS who had undergone micro TESE previously were re-evaluated between May 2007 and May 2012. Testes were measured and testicular volume was calculated by orchidometer and by scrotal ultrasonography in all patients All patients underwent repeated micro TESE. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone levels and testicular volume of the patients with and without successful sperm retrieval were compared statistically. A p value of less than 0.05 was considered statistically significant. The mean age of the patients was 30.3 years. The mean testicular volume was 2.08 and 2.1 mL for right and left testes respectively. The comparisons of serum FSH, LH, testosterone levels and testicular volume between patients with and without successful sperm retrieval did not show any significant difference. Three of the 18 patients who underwent repeated micro TESE, had successful sperm retrieval and repeated TESE failed in 15 patients. Three patients with successful sperm retrieval underwent intracytoplasmic sperm injection using retrieved testicular spermatozoa. Two embryos for each patient which were determined as healthy were transferred to the wives of the patients. Pregnancy occured in one of them and a healthy female infant was born. We conclude that consideration and hope must be given for a repeated micro TESE in patients with KS, even with a minimal chance of success.

- Outcome of microdissection TESE compared with conventional TESE in non-obstructive azoospermia: a systematic review.
- Deruyver Y, Vanderschueren D, Van der Aa F.Author information Department of Urology, UZ Leuven, Leuven, Belgium.AbstractRetrieval of spermatozoa is unfortunately still only successful in a subset of patients suffering from non-obstructive azoospermia (NOA) by conventional testicular sperm extraction (TESE). Microdissection TESE may have some theoretical benefits over conventional TESE, but uncertainty exists about its superiority. The objective of this systematic review was therefore to compare the efficacy and safety of microTESE with conventional TESE in men with NOA. The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Literature was searched for studies comparing outcome of conventional TESE with microdissection TESE. Primary outcome was sperm retrieval rate (SRR). Secondary outcomes were clinical predictors of sperm retrieval as well as complication rate. Of 62 articles, a total of seven studies were included in the final analysis. Overall SRR was significantly higher in the microTESE group in comparison with conventional TESE in five of these studies. Overall sperm retrieval ranged from 16.7 to 45% in the conventional TESE vs. 42.9 to 63% in the microTESE group. A sub-analysis of the SRR according to testicular histology was available in four of the selected articles. MicroTESE in men with Sertoli cell only syndrome and hypospermatogenesis carried a small but significant more favourable outcome according to, respectively, two and one of the studies. Correlation of serum follicle stimulating hormone and testicular volume with positive outcome was variable. Fewer complications were observed on ultrasound examination after microTESE procedure. Clinical randomized studies comparing microTESE with conventional TESE in NOA are still lacking to date. Pseudo-randomized prospective data, however, show more favourable sperm retrieval in NOA for microTESE, especially in histological patterns of patchy spermatogenesis such as Sertoli cell only syndrome. However, in patients with uniform histological patterns such as maturation arrest outcome of microTESE seems less favourable.
