Lifestyle implications of the paradox and management of oxidative stress in sperm

The Journal of Physiology, Volume 604, Issue 3, Page 1028-1044, 1 February 2026.
Abstract figure legend Lifestyle factors influencing male fertility. Schematic overview of lifestyle factors with beneficial (left) and detrimental (right) effects on male fertility. A balanced diet, regular moderate physical activity and stress management strategies support sperm function and redox homeostasis.

A microRNA cluster in the Fragile-X region expressed during spermatogenesis targets FMR1. [PDF]

, 2019
Testis-expressed X-linked genes typically evolve rapidly. Here, we report on a testis-expressed X-linked microRNA (miRNA) cluster that despite rapid alterations in sequence has retained its position in the Fragile-X region of the X chromosome in ...

Coiled-coil domain containing 42 (Ccdc42) is necessary for proper sperm development and male fertility in the mouse [PDF]

, 2016
Spermiogenesis is the differentiation of spermatids into motile sperm consisting of a head and a tail. The head harbors a condensed elongated nucleus partially covered by the acrosome-acroplaxome complex.

Comparative Evaluation of Two Microfluidic Sperm Sorting Devices: Laboratory Assessment of Sperm Quality and Retrospective Analysis of Embryological Outcomes Following Intracytoplasmic Sperm Injection

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose Density gradient centrifugation (DGC) enriches motile sperm but may increase sperm DNA fragmentation (SDF), whereas microfluidic sperm sorting devices, such as ZyMōt and CA0, enable centrifugation‐free selection with lower SDF. Direct comparisons are limited, and their relative clinical efficacy remains unclear.

The Three Pillars of ATP Production in Mammalian Sperm: Integrating Gluconeogenesis Into the Metabolic Framework

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose Mammalian sperm require a large amount of ATP to sustain motility. While glycolysis and oxidative phosphorylation (OXPHOS) are established ATP sources, they cannot fully explain motility maintenance under glucose‐deprived conditions.

Long‐Read Sequencing of CAH and ADPKD Provides Novel Insights Into the Genetic Diagnosis of Male Infertility

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose This study aimed to evaluate the utility of long‐read sequencing (LRS) in identifying variants of congenital adrenal hyperplasia (CAH) and autosomal dominant polycystic kidney disease (ADPKD) in infertile men, which may help further clarify genetic diagnosis and support genetic counseling and reproductive management. Methods A total of
