Apigenin Attenuates Paroxetine-Induced Ovarian Alterations in Female Rats

Abstract

Paroxetine, a selective serotonin reuptake inhibitor commonly used to treat various psychiatric disorders, may adversely affect female reproductive function. Although apigenin has been shown to ameliorate reproductive abnormalities and ovarian dysfunction, its effect on paroxetine-induced reproductive toxicity in females remains unclear. Therefore, this study investigated the potential protective effects of apigenin against paroxetine-induced reproductive alterations in female rats. Female rats with regular estrous cycles were randomly assigned to four groups (n = 9 per group): control, apigenin, paroxetine, and paroxetine + apigenin. The rats received saline, apigenin (20 mg/kg), paroxetine (10 mg/kg), or their combination by oral gavage once daily for about 29 consecutive days. Compared with paroxetine treatment alone, apigenin co-administration restored decreased serum anti-M & uuml;llerian hormone (AMH) levels, enhanced PAS reactivity in the zona pellucida, reduced ovarian iNOS immunoreactivity, increased follicle and corpus luteum numbers, and increased ovarian VEGF immunoreactivity. However, apigenin administration alone was associated with reduced testosterone levels and alterations in certain ovarian and uterine histological features in female rats. In conclusion, the findings suggest that apigenin may ameliorate paroxetine-induced reproductive alterations in female rats by modulating AMH levels, follicle and corpus luteum numbers, and ovarian histochemical and molecular parameters.
