Potentially toxic elements impair male reproductive function through oxidative stress, DNA damage, mitochondrial dysfunction, inflammation, endocrine disruption and epigenetic alterations. Antioxidants, phytochemicals, chelating agents and healthy lifestyle interventions may help mitigate testicular toxicity and preserve fertility.

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.

Chromosome Aberrations in Mouse Spermatocytes and Oocytes Exposed to 300R ϒ-Radiation: A Comparison
It has been repeatedly demonstrated that radiation induces chromosome aberrations in mouse oocytes and spermatocytes. However, the results of previous studies, in which the frequency of aberrations recovered from irradiated oocytes and spermatocytes were

Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis
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 ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances
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 ...

P15 | PHB/JAK/H3Y41PH AXIS REGULATES MEIOTIC RECOMBINATION IN SPERMATOGENESIS
Previously, we have shown that human sperm Prohibitin (PHB) expression is significantly negatively correlated with mitochondrial ROS levels but positively correlated with mitochondrial membrane potential and motility.

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

Homologous chromosomes pair normally and achieve initial synapsis in Hfm1−/− spermatocytes.
(a) Immunostaining of SYCP3 in wild-type and Hfm1−/− spermatocytes. Examples of pachytene-like spermatocytes are shown. Arrows mark sites of synaptic defects. XY and X-Y indicate positions of tightly and loosely associated sex chromosomes, respectively. (
