An increased risk of testicular cancer in men with infertility and poor semen quality has been reported. In view of the high cure rates for testicular germ cell tumours, increasing clinical importance is being placed on the protection of fertility. High-dose cytostatic therapy may be expected to cause long-term infertility. Thus, the standard procedure

Intra-Testicular Sperm Extraction
2017In the scenario of medically assisted reproduction, sperm retrieval techniques (SRTs) represent a concrete possibility to find, freeze, and use spermatozoa in men with a diagnosis of azoospermia. Therefore, many infertile couples because of a severe male factor can achieve a biological offspring.

Micro-testicular Sperm Extraction
2012The condition of nonobstructive azoospermia (NOA) defines men with testicular failure who have severely deficient sperm production with no sperm in the ejaculate. NOA is the underlying diagnosis in approximately 10% of men seeking fertility evaluation.

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 ...

TESE is considered the best procedure for identifying a tubule for spermatozoa retrieval. This technique improves the SRR to around 50%. However, it has been unclear whether it is useful in patients in whom conventional TESE has failed. We compared the outcome of microdissection TESE in patients in whom conventional TESE failed to that in patients who ...

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.

“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 ...

[Testicular and epididymal sperm extraction surgery].
Progres en urologie : journal de l'Association francaise d'urologie et de la Societe francaise d'urologie, 2023Testicular and epididymal sperm extraction surgery is a frequent procedure. However, to date, there has been no French consensus on the technique to be preferred in the various situations of male infertility and on the best way to perform them. We therefore decided to proceed with a formalized expert consensus, using the method recommended by the ...

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
