Lycopene supplement mitigates polystyrene microplastics (PS-MPs)-induced reproductive alteration in rats via modulation of steroidogenic enzymes, inhibition of apoptosis and oxido-inflammatory reaction

Increasing levels of polystyrene microplastics (PS-MPs) in the environment poses huge global health threat. Prolonged exposure to PS-MPs results in both male and female infertility, with a deleterious effect on reproductive health. In rats, the disruptive effects of chemotoxicants have been countered by lycopene (LYC). This study examined the protective benefits of lycopene (LYC) against spermatological damage and hormonal alterations brought on by polystyrene microplastics (PS-MPs) in male rats. Twenty Wistar rats were split into four groups of five rats, each consisting of: the control group, the PSMPs treatment group, the PS-MPs + LYC co-treatment group, and the LYC supplementation group. Severe testicular histological damage was seen to have resulted from exposure to PS-MPs. The PS-MPs treatment dramatically reduced the antioxidant enzyme activities while raising the levels of ROS and MDA, thus reducing sperm progressive motility. Also, spermatological damage and hormonal alterations brought on by polystyrene microplastics (PS-MPs) were also prevented by the effects of lycopene (LYC). In conclusion, LYC supplementation has the ability to reduce the harmful effects of PS-MPs on the male reproductive system. Accordingly, LYC prevented PS-MPs-induced spermatological damage and reproductive hormonal changes in rats via its anti-oxidant, androgenic, anti-apoptotic, anti-inflammatory properties.
