Intrauterine Growth and Male Reproductive Health: A Follow‐up Study From the Danish National Birth Cohort

Andrology, EarlyView.
ABSTRACT Background Reduced intrauterine growth might affect male reproductive health later in life, however, existing research remain inconclusive. Objectives To investigate the association between placental weight and birthweight Z‐scores and semen characteristics, testes volume, and reproductive hormone levels in young men.

Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

Andrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Maternal Consumption of Artificially Sweetened Beverages in Pregnancies and Biomarkers of Fecundity in Adult Sons

Andrology, EarlyView.
ABSTRACT Introduction Maternal intake of artificial sweeteners in beverages (ASB) during pregnancy may have a programming effect on offspring health, including biomarkers of male fecundity. Objective We investigated whether maternal intake of ASB during pregnancy was associated with biomarkers of male fecundity in adult sons.

Diabetes‐Induced Testicular Injury: Potential Protective Roles of Curcumin, Garcinia kola, and Momordica charantia in Rats

Andrology, EarlyView.
ABSTRACT Background Diabetes mellitus (DM) induces multifaceted cellular and structural alterations in the male reproductive system, thereby predisposing to infertility. Objectives This study aimed to evaluate the morphological, stereological, biochemical, histopathological, and ultrastructural changes induced by DM in testicular tissue, and to ...

Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

Andrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.

Role of ANO1‐Expressing PDGFRα+ Smooth Muscle Cells in Generating Spontaneous Phasic Contractions of the Rodent Epididymis

Andrology, EarlyView.
ABSTRACT Background Spontaneous phasic contractions (SPCs) in the epididymal duct play an important role in transport and maturation of sperm. In proximal cauda of the rat epididymis, platelet‐derived growth factor receptor α (PDGFRα)‐positive smooth muscle cells (SMCs) generate ANO1 Ca2+‐activated chloride channels (CaCCs)‐dependent spontaneous ...

Obesity Is an Independent Risk Factor for Oligozoospermia, With Co‐Existing Hyperglycemia Exacerbating Risks of Asthenozoospermia and Elevated Sperm DNA Fragmentation

Andrology, EarlyView.
ABSTRACT Background Metabolic health plays a critical role in maintaining male fertility and may influence offspring health. Therefore, it is necessary to incorporate metabolic indicators into the clinical assessment of male fertility. However, the relationships between different metabolic abnormalities and semen quality remain incompletely understood.

Prevalence of Spermatozoa in the Ejaculate of Adolescents With Klinefelter Syndrome: Implications for Fertility Counseling

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is the most common genetic cause of male infertility and is associated with nonobstructive azoospermia. Advances in surgical sperm retrieval techniques have enabled biological fatherhood in a subset of men with KS.

Occupational Physical Activity Is Negatively Associated With Semen Quality

Andrology, EarlyView.
ABSTRACT Background Lifestyle factors have been associated with semen quality and have been implicated in the reported global decline in semen parameters. Moderate physical activity has been linked to improved semen quality; however, the association between occupational physical activity and semen quality is limited.
