Zearalenone (ZEA) is a non-steroidal xenoestrogen mycotoxin produced by many fungal species, which are common contaminants of cereal crops destined for worldwide human and animal consumption. ZEA has been reported in various male reproduction dysfonctions, including decreased fertility potential. In this report, the direct effect of ZEA on the immature Sertoli TM4 cell line was evaluated. The results show that high concentrations of ZEA increase reactive oxygen species via the activation of MAPK signaling. Transcriptome analysis was performed on the TM4 cell line treated with ZEA, and genes involved in sex differentiation (, , , ) and extracellular matrix (ECM) formation (, , , , , , ) were identified at the center of the functional protein association network, suggesting that ZEA could be detrimental to the early steps of Sertoli cell differentiation.

Cisplatin (CIS) is a widely used chemotherapeutic agent, but its side effects, such as oxidative stress, inflammation, and apoptosis, often lead to male reproductive damage. Oxidative stress, primarily caused by the excessive generation of reactive oxygen species (ROS), plays a critical role in disrupting testicular homeostasis, resulting in spermatogenic impairment and tissue injury. L-cysteine (CYS), a semi-essential amino acid with potent antioxidant and anti-inflammatory properties, may offer protection against CIS-induced oxidative damage.

Bisphenol A (BPA) is an endocrine disruptor universally present in food packaging, which may cause oxidative stress and reproductive toxicity through migration to food and ingestion then. Both Mori Fructus and selenium have excellent antioxidant ability and good therapeutic effects on reproductive improvement. Hence, in this work, Mori Fructus polysaccharide (MFP) was selected as a stabilizer to synthesize MFP‑selenium nanoparticles (MFP-SeNPs) by chemical reduction method.

Research on heat-induced food contaminants, such as furan, has shown its harmful effects on various systems. However, the impact of furan on Sertoli cells, a crucial male reproductive system cell, has not been studied. The investigation involved the treatment of furan to TM4 Sertoli cells at various concentrations (750, 1500, and 3000 µM) over a period of 24 h.

Background/objectives: Late-onset hypogonadism (LOH), characterized by declining testosterone levels with age, negatively affects the health of men, causing physical, psychological, and sexual dysfunction. Conventional testosterone replacement therapies have side effects, which has led to interest in natural alternatives. We investigated the effects of a standardized fermented extract (FME) on oxidative stress-induced damage in TM3 Leydig and TM4 Sertoli cells.
