Microdissection TESE versus conventional TESE for men with nonobstructive azoospermia undergoing sperm retrieval

International Brazilian Journal of Urology, 2022
Sperm retrieval techniques are classically used to harvest sperm from the epididymis and testis of men with azoospermia seeking fertility (1). After a successful sperm retrieval, intracytoplasmic sperm injection (ICSI) is mandatory because epididymal and

Predictive factors for successful sperm retrieval by microdissection testicular sperm extraction in men with nonobstructive azoospermia and a history of cryptorchidism

Asian Journal of Andrology, 2022
This study aims to explore the factors influencing the success rate of the microdissection testicular sperm extraction (Micro-TESE) in patients with nonobstructive azoospermia (NOA) and cryptorchidism.

A novel stepwise micro-TESE approach in non obstructive azoospermia [PDF]

, 2016
Background: The purpose of the study was to investigate whether micro-TESE can improve sperm retrieval rate (SRR) compared to conventional single TESE biopsy on the same testicle or to contralateral multiple TESE, by employing a novel stepwise micro ...

Combined Trifocal and Microsurgical Testicular Sperm Extraction Enhances Sperm Retrieval Rate in Low-Chance Retrieval Non-Obstructive Azoospermia

Journal of Clinical Medicine, 2022
Background: Low-chance retrieval non-obstructive azoospermic (NOA) patients are a subpopulation of NOA patients. The objective of this study is to compare the surgical outcome of microsurgical-assisted testicular sperm extraction (M-TeSE) and combined ...

#85 : Microdissection Testicular Sperm Extraction (Micro-Tese) in Men Non-Obstructive Azoospermia with Very Small Testicular Volume: A Case Series Report

Fertility & Reproduction, 2023
Background and Aims: Testicular atrophy is a common clinical manifestation of NOA, with a rate of 79.1%. The results of sperm retrieval using the mTESE method in a special NOA for testicular atrophy with volume [Formula: see text]5ml are currently ...

Histology and sperm retrieval among men with Y chromosome microdeletions

Translational Andrology and Urology, 2021
In this review of Y chromosome microdeletions, azoospermia factor (AZF) deletion subtypes, histological features and microTESE sperm retrieval rates are summarized after a systematic literature review. PubMed was searched and papers were identified using

Dynamics of 5-methylcytosine and 5-hydroxymethylcytosine during pronuclear development in equine zygotes produced by ICSI [PDF]

, 2017
Background: Global epigenetic reprogramming is considered to be essential during embryo development to establish totipotency. In the classic model first described in the mouse, the genome-wide DNA demethylation is asymmetric between the paternal and the ...

Prediction Models for Successful Sperm Retrieval in Patients with Non-Obstructive Azoospermia Undergoing Microdissection Testicular Sperm Extraction: Is There Any Room for Further Studies?

Journal of Clinical Medicine, 2021
Several prediction models for successful sperm retrieval (SSR) in patients with azoospermia due to spermatogenic dysfunction (also termed non-obstructive azoospermia—NOA) have been developed and published in the past years, however their resulting ...
