Sperm retrieval success and testicular histopathology in idiopathic nonobstructive azoospermia

open access: yesAsian Journal of Andrology, 2020
Prior studies have investigated sperm retrieval rates in men with nonobstructive azoospermia (NOA) secondary to specific etiologies, yet most cases of NOA are idiopathic.

Association between JMJD1A Expression and Sperm Retrieval in Non-Obstructive Azoospermic Patients

open access: yesCell Journal, 2017
Identification of molecular markers which can predict the outcome of sperm retrieval non-invasively in patients with non-obstructive azoospermia (NOA) are valuable in clinical andrology.

Seminal plasma extracellular vesicles tRF-Val-AAC-010 can serve as a predictive factor of successful microdissection testicular sperm extraction in patients with non-obstructive azoospermia

open access: yesReproductive Biology and Endocrinology, 2022
Background There is a lack of biomarkers for distinguishing non-obstructive azoospermia (NOA) patients with successful sperm retrieval (Sp+) from those with failed sperm retrieval (Sp-).

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

open access: yesAdvanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Microsurgical Testicular Sperm Extraction Results in Nonobstructive Azospermic Disease and Evaluation of the Factors Affecting These Results

open access: yesActa Medica Alanya, 2017
Aim: To investigate the hormonal properties and results of 71 patients, who were diagnosed with nonobstructive azoospermia (NOA) and performed micro-TESE (microsurgical testicular sperm extraction) at  our clinic, and the relationship of these results ...

IL1R2 Marks and Sorts a Spermatogonial Stem Cell Population Critical for Restoring Spermatogenesis Upon Interruption in Mammals

open access: yesAdvanced Science, EarlyView.
Spermatogonial stem cells (SSCs) provide critical support to spermatogenesis. Here, the author established Il1r2 as a sorting marker for SSCs, with which further insights into the SSC heterogeneity and dynamic features can be obtained. They also confirmed findings in both mouse and human, thus validating IL1R2 as the surface marker for isolating and ...

A comprehensive assessment of predictors of fertility outcomes in men with non-obstructive azoospermia undergoing microdissection testicular sperm extraction

open access: yesReproductive Biology and Endocrinology, 2020
Background Microdissection testicular sperm extraction (microTESE) in men with non-obstructive azoospermia (NOA) is the procedure that results in the highest number of sperm cells retrieved for in vitro fertilization (IVF).

Micro-TESE Outcomes for Non-Obstructive Azoospermia — The First Australian Series

open access: yesFertility & Reproduction, 2022
Background: Micro-dissection testicular sperm extraction (micro-TESE) for non-obstructive azoospermia (NOA) was shown to achieve the best sperm retrieval rate (SRR) compared to other techniques.

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

open access: yesAdvanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...
