Ghyasvand et al., performed another study to evaluate the levels of lycopene, beta-carotene and retinol in serum and their relationship with sperm DNA disruption and lipid peroxidation in infertile and normo-spermic males, and concluded that lycopene, beta-carotene, and retinol can decrease sperm DNA fragmentation and lipid peroxidation via their antioxidant effect [110]
In addition, it has been shown that midbrain dopamine axons can synapse onto OLs in vivo and that some Olig2 + /PDGFR + OPCs can express Drd1/Drd2 receptors (Caldwell et al., 2023), implying that dopaminergic fibers can directly signal to OPCs, potentially influencing myelination
