The use of deidentified organ donor testes for research

Andrology, Volume 14, Issue 8, Page 2359-2372, November 2026.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Research Progress on the Pathogenesis and Diagnostic Biomarkers of Azoospermia

Biomolecules
Azoospermia represents the most severe manifestation of male infertility and is classified into obstructive azoospermia (OA) and non-obstructive azoospermia (NOA).

Should men with idiopathic obstructive azoospermia be screened for genitourinary tuberculosis?

Journal of Human Reproductive Sciences, 2015
Objective: Infertility may be the sole manifestation of genitourinary tuberculosis (TB) and men with idiopathic obstructive azoospermia are often screened for TB using semen polymerase chain reaction (PCR) test. We assessed the benefits of such screening.

Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

The outcome of ART in males with impaired spermatogenesis

Journal of Human Reproductive Sciences, 2008
Aims: This study was conducted to evaluate the outcomes of assisted reproductive technology (ART) procedures, viz., intrauterine insemination (IUI), in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in males with impaired ...

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, Volume 14, Issue 7, Page 2166-2179, October 2026.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

Andrology, Volume 14, Issue 7, Page 2329-2346, October 2026.
ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

The frequency of follicle stimulating hormone receptor gene polymorphisms in Iranian infertile men with azoospermia

Iranian Journal of Reproductive Medicine, 2015
Background: Azoospermia is the medical condition of a man not having any measurable level of sperm in his semen. Follicle stimulating hormone (FSH) is a member of the glycoprotein hormone family that plays an important role in human reproduction because ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

Andrology, Volume 14, Issue 7, Page 1962-1970, October 2026.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...
