The aim of this study was to investigate the possible therapeutic effects of curcumin (CUR), against acrylamide (AA)-induced toxic effects on Leydig cells. The AA and CUR-treated cells were evaluated for cell viability, lipid peroxidation, reactive oxygen species (hydroxyl radical and hydrogen peroxide), antioxidant levels (glutathione peroxidase, glutathione-S-transferase, and catalase), apoptosis/necrosis rates and phosphorylation status of mitogen-activated protein kinases (MAPKs). Leydig cells were exposed to four concentrations of AA (1, 10, 100, 1000 µM) in the presence and absence of CUR (2.5 µM) for 24 hours. According to the present result, AA concentration-dependently, increased the oxidative stress parameters and suppressed the antioxidant enzyme levels, meanwhile induced apoptosis and activated the phosphorylation of extracellular signal-regulated kinase, p38, and c-Jun NH -terminal kinase. Moreover, CUR ameliorated the detrimental effects of AA. Thus, AA-induced apoptosis through activation of the MAPK signaling pathway and CUR has a protective effect against AA-induced damage in Leydig cells.

Long noncoding RNAs (LncRNAs) play essential roles in numerous biological processes in mammals, such as reproductive physiology and endocrinology. Cryptorchidism is a common male reproductive disease. Circadian rhythms are actively expressed in the reproductive system.

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.

Sulfur dioxide (SO) is a ubiquitous environmental pollutant that has been shown to be toxic to the male reproductive system, but the underlying mechanism remains unclear. Therefore, the SO-treated mice and primary Leydig cell models were established to investigate the effects of SO on the production of testosterone and its specific mechanism. The results demonstrated that SO activated the ERK1/2 signaling pathway, leading to increased key proteins expression of testosterone biosynthesis and elevated testosterone levels.

4-Cyano-4'-ethoxybiphenyl (EBCN) is a representative cyano liquid crystal monomer (LCM). While prior studies have documented the widespread occurrence of LCMs in diverse environmental and biological samples, research on their reproductive effects in vivo remains limited. This study employed 35-day and 70-day exposure models in mice to assess the short-term and long-term effects of environmentally relevant concentrations of EBCN on testicular health.

Crude oil contamination has been shown to impair reproduction in aquatic animals through carcinogenic and genotoxic properties. Here, we assessed the endocrine-disrupting function of crude oil on male reproductive system based on testicular histology, sex steroid hormones, and fertility endpoints in adult male goldfish (Carassius auratus), which were exposed to 0.02- to 2-mg/L crude oil for 21 days (Experiment #1) or to 5- to 250-mg/L crude oil for 9 days (Experiment #2).
