This study investigated the potential effects of China dust (CD) exposure on cyclophosphamide (CP)-induced testicular toxicity in mice, focusing on spermatogenesis and oxidative damage. CP treatment reduced testicular and epididymal weight and sperm motility and enhanced sperm abnormality. Histopathological examination presented various morphological alterations in the testis, including increased exfoliation of spermatogenic cells, degeneration of early spermatogenic cells, vacuolation of Sertoli cells, a decreased number of spermatogonia/spermatocytes/spermatids, along with a high number of apoptotic cells. In addition, the testis exhibited reduced glutathione (GSH) levels and glutathione reductase (GR) activity and enhanced malondialdehyde (MDA) concentration. Meanwhile, CD exposure exacerbated testicular histopathological alterations induced by CP. CD exposure also aggravated oxidative damage by increasing the lipid peroxidative product MDA and decreasing GSH levels and antioxidant enzyme activities in the testis. These results suggest that CD exposure exacerbates CP-induced testicular toxicity in mice, which might be attributed to the induction of lipid peroxidation and reduced antioxidant activity.

Background: Methotrexate (MTX), a folate antagonist, is widely used in the treatment of tumors and autoimmune diseases such as rheumatoid arthritis (RA), due to its antiproliferative, antimetabolic, and potent anti-inflammatory properties. However, high-dose or long-term use of MTX can result in toxicity to the gastrointestinal, hemopoietic, and reproductive tissues. Yunpi Jiedu Tongluo Qushi Decoction (YJT), an effective Chinese herbal formula, is utilized in RA treatment to mitigate the toxic and side effect of MTX.

Copper (Cu) is an essential micronutrient in various enzymatic and physiological functions. However, excessive copper intake, mainly resulting from industrial emissions and improper agricultural practices, has raised growing concerns due to its toxicological effects, particularly on the male reproductive system. This review summarizes current research progress on copper-induced reproductive toxicity in males, emphasizing its impact on sperm quality, androgen production, and testicular structure and function.

Phthalates (PEs) are widespread in environment, and human beings are unavoidably exposing to the mixture of PEs, which may induce male reproductive health risks. In order to investigate the mechanism of male reproductive injuries caused by the mixture of di-2-ethylhexyl phthalate, dibutyl phthalate and butyl benzyl phthalate (MPEs), male rats were orally exposed to 16 mg/kg/d MPEs (L-MPEs) and 450 mg/kg/d MPEs (H-MPEs) for 90 days, and the results showed that MPEs decreased the weights of testes, epididymis and periepididymis fat, decreased serum levels of male hormones, increased abnormal sperm rate, and caused testicular histopathological damages, such as atrophy and cavitation of seminiferous tubules, spermatids exfoliation, Leydig cells hyperplasia and accumulation of lipid droplets in the testicular interstitium. Testicular transcriptomic analysis identified 100 differently expressed genes (DEGs) in L-MPEs group and 10,880 DEGs in H-MPEs group, and these DEGs mainly involved in signaling pathways of focal adhesion, PI3K-Akt, AGE-RAGE, axon guidance, PPAR, MAPK and etc.

Background: Cisplatin is a commonly used chemotherapeutic across numerous cancer types that can cause neurotoxicities in patients, including peripheral sensory neuropathy, tinnitus, hearing loss, and vertigo.
Objective: We aimed to evaluate, for the first time, how genetic ancestry impacts cisplatin-induced neurotoxicities and if disparities are related to population differences in allele frequency.
Methods: In a cohort of cisplatin-treated testicular cancer survivors, relationships between genetic ancestry and neurotoxicities, medications, and lifestyle factors were assessed using logistic regression and Kruskal-Wallis tests and multiple pairwise comparisons using the Wilcoxon rank-sum test (Benjamini-Hochberg adjustment).

Radiation and doxorubicin (Dox) exert destructive effects on testicular tissue. Resveratrol, a natural antioxidant, may protect the spermatogenic system against the toxic effects of these agents. This study evaluated the protective and antioxidant properties of resveratrol-loaded solid lipid nanoparticles (RES-SLNs) against Dox- and radiation-induced testicular injury in mice.
