Microdissection testicular sperm extraction outcomes in azoospermic patients with bilateral orchidopexy

Andrology, 2023
AbstractBackgroundCryptorchidism is considered to be one of the most common causes of non‐obstructive azoospermia. There are several surgical techniques to retrieve sperm in these patients. Microdissection testicular sperm extraction (m‐TESE) is a recent sperm retrieval technique which is considered to be a safe, non‐blind, and feasible method ...

Conventional Versus Microdissection Testicular Sperm Extraction for Nonobstructive Azoospermia

The Journal of Urology, 2002
We established a practical and safe strategy for testicular sperm extraction (TESE) in patients with nonobstructive azoospermia and compared conventional with microdissection TESE.In a retrospective comparative study 46 patients, including 22 with obstructive and 24 with nonobstructive azoospermia, underwent conventional TESE.

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 ...

Microdissection Testicular Sperm Extraction: Effect of Prior Biopsy on Success of Sperm Retrieval

Journal of Urology, 2007
We determined the effect of prior biopsies with no sperm seen on the chance of sperm retrieval with microdissection testicular sperm extraction in men with nonobstructive azoospermia.A total of 311 men with NOA underwent microdissection testicular sperm extraction.

Duration of Microdissection Testicular Sperm Extraction Procedures: Relationship to Sperm Retrieval Success

Journal of Urology, 2011
We evaluated the operative time of microdissection testicular sperm extraction in successful and failed procedures to identify the chance of sperm retrieval during longer microsurgical procedures.A total of 793 men with nonobstructive azoospermia underwent a first attempt at microdissection testicular sperm extraction from January 2000 to September ...

Localization of Sperm During Microdissection Testicular Sperm Extraction in Men with Nonobstructive Azoospermia

Journal of Urology, 2013
We determined the location where sperm were identified during microdissection testicular sperm extraction and characterized the subset of patients for whom complete bilateral exploration was most beneficial.A total of 900 men underwent a first attempt at microdissection testicular sperm extraction.

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 ...

Undescended Testis Does Not Affect the Outcome of Microdissection Testicular Sperm Extraction

Urology, 2020
To determine the sperm retrieval rates (SRRs) and predictive factors of patients with a history of undescended testis after testicular sperm extraction (TESE).A total of 311 patients were diagnosed with nonobstructive azoospermia (NOA) and underwent TESE were included in this study.

Microdissection testicular sperm extraction in Finland – results of the first 100 patients

Acta Obstetricia et Gynecologica Scandinavica, 2017
AbstractIntroductionTesticular microdissection sperm extraction (MD‐TESE) combined with intracytoplasmic sperm injection (ICSI) has made biological fatherhood possible for many men with the most severe form of male infertility, non‐obstructive azoospermia.

Successful microdissection testicular sperm extraction for men with non-obstructive azoospermia

Reproductive Biology, 2018
Non-obstructive azoospermia (NOA) is the most severe form of male infertility, defined by lack of spermatozoa in the ejaculate caused by impaired spermatogenesis. The chance of biological fatherhood of these men has been improved since the introduction of microdissection testicular sperm extraction (MD-TESE) combined with intracytoplasmic sperm ...
