Isoliquiritigenin ameliorates paroxetine-induced sexual dysfunction in male albino mice

Paroxetine (PRX), a widely prescribed antidepressant, often leads to sexual dysfunction. The available man-agement options such as sildenafil (SDF), are associated with side effects. The present study investigates the fertility-boosting properties of isoliquiritigenin (ISL) on PRX-induced sexual dysfunction in male mice. We allocated fertile mice into six different groups (n = 5): group I-DMSO; group II-PRX; group III-co-administered PRX and SDF; group IV-ISL alone; group V-co-administered PRX and ISL (low dose); and, group VI-co -administered PRX and ISL (high dose). 14 days post treatment, animals were sacrificed, and the weights of the testis and epididymis were evaluated. Furthermore, sperm parameters, testicular and epididymal antioxidant levels, serum testosterone and nitric oxide (NO) levels, histoarchitecture of testis and epididymis, and markers of cellular toxicity were assessed. Results revealed that the PRX administration reduced organ weights, sperm count, intact acrosome, catalase (CAT), superoxide dismutase (SOD), glutathione (GSH), serum testosterone, and NO levels, and increased sperm abnormalities and MDA levels (a biomarker for lipid peroxidation). Additionally, we observed damage in the testis and epididymis. The toxicity biomarker study revealed a higher concentration of SGOT, SGPT, and ALP enzymes in the PRX-treated group. However, the co-administration of PRX with ISL ameliorated the adverse effect of PRX on the parameters mentioned above. The PRX+ISL (high) results were almost at par with the PRX+SDF group. The group that received ISL alone showed overall improvements. In conclusion, our comprehensive panel of tests indicates that ISL could be helpful in managing sexual dysfunction.

Automated summary

This study investigates the potential of isoliquiritigenin (ISL) to enhance fertility in male mice with sexual dysfunction induced by the widely prescribed antidepressant paroxetine (PRX). The results show that PRX reduces organ weights, sperm count, intact acrosome, antioxidant levels, testosterone and nitric oxide (NO) levels, and increases sperm abnormalities and lipid peroxidation levels. PRX also causes damage in the testis and epididymis. However, co-administration of PRX with ISL alleviates the adverse effects and ISL alone shows overall improvements. Therefore, ISL may be helpful in managing sexual dysfunction.
