Macrophage-Related Testicular Inflammation in Individuals with Idiopathic Non-Obstructive Azoospermia: A Single-Cell Analysis

International Journal of Molecular Sciences, 2023
Male infertility is a global issue that seriously affects reproductive health. This study aimed to understand the underlying causes of idiopathic non-obstructive azoospermia (iNOA), which is a type of male infertility with unknown origins that accounts ...

An artificial neural network model to diagnose non-obstructive azoospermia based on RNA-binding protein-related genes

Aging, 2023
Non-obstructive azoospermia (NOA) is a severe form of male infertility, but its pathological mechanisms and diagnostic biomarkers remain obscure. Since the dysregulation of RNA-binding proteins (RBPs) had nonnegligible effects on spermatogenesis, we ...

Nomogram based on a circular RNA biomarker for predicting the likelihood of successful sperm retrieval via microdissection testicular sperm extraction in patients with idiopathic non-obstructive azoospermia

Frontiers in Endocrinology, 2023
Background Many circular RNAs (circRNAs) are specifically expressed in the testes and seminal plasma of patients with non-obstructive azoospermia (NOA), highlighting them as potential predictors of microdissection testicular sperm extraction (micro-TESE)

Imaging methods for seminal tract obstruction

Андрология и генитальная хирургия, 2022
Differential diagnosis between obstructive and non-obstructive azoospermia is an important task in clinical management of infertile patients. Chances of extracting sperm in obstructive azoospermia are high enough to inform the couple about favorable ...

Characterization of Non-Obstructive Azoospermia in Men Using Gut Microbial Profiling

Journal of Clinical Medicine, 2023
(1) Background: Non-obstructive azoospermia (NOA) is a complex multifactorial disease and the causes of most NOA cases remain unknown. (2) Methods: Here, we performed comprehensive clinical analyses and gut microbial profiling using shotgun metagenomic ...

Morphological features of testicular and epididymal spermatozoa obtained from azoospermic men.

Морфологія, 2020
Background. Studying of morphological features of spermatozoa obtained from men with azoospermia is due to the high rate of infertile marriages with a male factor. It is extremely important to estimate spermatozoa morphological characteristics, which can

Proposed age-stratified reference intervals of FSH derived from normozoospermic men

Asian Pacific Journal of Reproduction, 2021
Objective: To demonstrate that serum follicle-stimulating hormone (FSH) in men rises with age, and to explore FSH reference intervals of age-related partitioning.

Cut-off Value of Testosterone and FSH Level In Patient With Azoospermia [PDF]

, 2016
Follicle-stimulating hormone(FSH) and Testosterone are important for spermatogenesis. Increased serum FSH and decreased testosterone are related to abnormal spermatogenesis.
