Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

Andrology, EarlyView.
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 ...

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

In Vitro Sperm–Epididymosomes Interaction Immediately Before Fertilization Changes Sperm Fertility Potential

Andrology, EarlyView.
ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...

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.
