Histological Findings in Testes of Baboons (Papio spp.) and Dwarf Bucks (Capra hircus) Subject to Repeated Immunisation Against GnRH

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Long‐term repeated immunisation against GnRH resulted in the absence of active spermatogenesis and may lead to irreversible infertility in dwarf bucks and baboons. Histological examination revealed a marked reduction of the seminiferous tubular lumen, complete depletion of germ cells, germ cell vacuolization and tubular hyalinization.

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

Andrology, Volume 14, Issue 7, Page 2150-2159, October 2026.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

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 ...

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

Andrology, Volume 14, Issue 7, Page 1906-1928, October 2026.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in

SIRT1 in Neurodegenerative Diseases: Molecular Mechanisms, Disease Relevance, and Therapeutic Potential

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
SIRT1, an NAD+‐dependent deacetylase, supports cognitive resilience by coordinating neuroprotection, synaptic plasticity, autophagy–lysosomal proteostasis, and mitochondrial energy homeostasis. Reduced or dysregulated SIRT1 is associated with protein aggregation, neuroinflammation, mitochondrial dysfunction, synaptic loss, and cognitive decline in ...
