Intra-Testicular Sperm Extraction

2017
In 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.

Sperm retrieval in infertile males: Comparison between testicular sperm extraction and testicular sperm aspiration techniques

Wiener Klinische Wochenschrift, 2003
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 ...

Salvage Microdissection Testicular Sperm Extraction After Failed Conventional Testicular Sperm Extraction in Patients With Nonobstructive Azoospermia

Journal of Urology, 2006
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 ...

Micro-testicular Sperm Extraction

2012
The 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.

TESTICULAR SPERM EXTRACTION WITH INTRACYTOPLASMIC SPERM INJECTION FOR NONOBSTRUCTIVE AZOOSPERMIA: TESTICULAR HISTOLOGY CAN PREDICT SUCCESS OF SPERM RETRIEVAL

Journal of Urology, 1999
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.

[Testicular and epididymal sperm extraction surgery].

Progres en urologie : journal de l'Association francaise d'urologie et de la Societe francaise d'urologie, 2023
Testicular 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, 2004
To 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

Focal Testicular Lesion After Sperm Extraction or Aspiration

American Journal of Roentgenology, 2001
OBJECTIVE. We describe the sonographic features of focal intratesticular lesions seen in men who underwent sperm retrieval procedures. CONCLUSION. Although many urologists believe that solid intratesticular masses are malignant until proven otherwise, a growing number of benign focal testicular lesions have been described.

Microdissection testicular sperm extraction: Prediction, outcome, and complications

International Journal of Urology, 2007
Abstract:  Testicular spermatozoa can be retrieved successfully by the testicular sperm extraction (TESE) procedure and used for intracytoplasmic sperm injection in cases of non‐obstructive azoospermia (NOA). The successful application of TESE depends on the identification of seminiferous tubules containing spermatozoa; testicular tubules of patients ...

Testicular sperm extraction: microdissection improves sperm yield with minimal tissue excision

Human Reproduction, 1999
Testicular sperm extraction (TESE) is often an effective method for sperm retrieval from men with non-obstructive azoospermia. However, TESE has been a blind procedure that does not identify the focal sperm-producing areas of the testicle until after tissue has been excised from the patient.
