Technical modification of testicular sperm extraction expedites testicular sperm retrieval

Fertility and Sterility, 2009
To determine the predictive value and the quality of supernatant sperm (SS) achieved by a simple laboratory technical modification after testicular sperm extraction (TESE).A retrospective analysis.An IVF unit in a university medical center.Azoospermic patients undergoing TESE between January 2001 and December 2006.Before the mechanical shredding, the ...

Do inflammatory markers such as NLRP3 and IL1‐β have an effect on the prediction of testicular sperm extraction success in infertile men?

Andrologia, 2022
Infertility is defined as the inability of couples to have a baby without contraception after at least 1 year of regular sexual intercourse. Mechanisms to explain inflammation in male infertility of unknown causes are still being investigated.

Systemic immune‐inflammation index, neutrophil‐lymphocyte ratio and platelet‐lymphocyte ratio are predictors of sperm presence in microdissection testicular sperm extraction

Andrologia, 2022
The aim of this study is to evaluate the value of the haematologic inflammatory parameters in predicting sperm retrieval rates during microdissection testicular sperm extraction (micro‐TESE).159 patients diagnosed with non‐obstructive azoospermia were ...

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.

A step closer to parenthood with non‐obstructive azoospermia: Unveiling the impact of microdissection testicular sperm extraction in Australia's largest single‐centre study

Australian and New Zealand journal of obstetrics and gynaecology
Non‐obstructive azoospermia (NOA) diagnosis poses challenges for couples seeking parenthood. Microdissection testicular sperm extraction (MD‐TESE) excels in retrieving testicular sperm cells for NOA cases.

Potential of testis-derived circular RNAs in seminal plasma to predict the outcome of microdissection testicular sperm extraction in patients with idiopathic non-obstructive azoospermia.

Human Reproduction, 2021
STUDY QUESTION Do testis-derived circular RNAs (circRNAs) in seminal plasma have potential as biomarkers to predict the outcome of microdissection testicular sperm extraction (micro-TESE) in patients with idiopathic non-obstructive azoospermia (NOA ...

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.

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 ...
