“Open” Biopsy of the Testis and Testicular Sperm Extraction
2012This chapter brie fl y describes “open” testicular biopsy as a method for obtaining tissue for cryopreservation, as well as the assessment of the histologic structure of the testicular parenchyma, including detection of carcinoma in situ. This chapter also illustrates the handling of testicular biopsy samples in cases of limited testicular tumors.

<i>Background:</i> The aim of the present study was to verify the feasibility of cryopreserving testicular tissue during the first diagnostic biopsy and then using thawed sperm to inseminate the partner’s oocytes. The expected advantages are: (i) minimal risk of not having spermatozoa available at the time of intracytoplasmic sperm ...

Improvements in using retrieved testicular spermatozoa in infertile males to achieve fertilization and pregnancy has enabled patients with clinical azoospermia and non-obstructive testicular failure to father children. In this review article, we compare the relative yields of the two major techniques for sperm retrieval in males with non-obstructive ...

We present treatment results of testicular sperm extraction with intracytoplasmic sperm injection for men with nonobstructive azoospermia and reevaluate the role of testicular histology on open diagnostic testicular biopsy as a predictor of sperm retrieval success.We evaluated 75 men diagnosed with nonobstructive azoospermia.

Successful testicular sperm extraction in Korean Klinefelter syndrome
Urology, 2004To evaluate the clinical features of Korean Klinefelter syndrome (KS) and the outcome of intracytoplasmic sperm injection using fresh testicular spermatozoa obtained by testicular sperm extraction from these infertile men. Most patients with KS have a nonmosaic 47,XXY karyotype, and about 3% of males with KS are mosaic (46,XY/47,XXY). Great variability

Microsurgical Testicular Sperm Extraction: Technical Considerations
2012Treatment of nonobstructive azoospermia (NOA) has changed radically over the past 15 years, evolving from a clinical diagnosis with no direct treatment options to a highly treatable entity. The condition of NOA is typically characterized by a man who has small volume testes and elevated FSH.
