Bisphenol F (BPF) is an environmental pollutant that has been implicated in sexual dysfunction. Omega 3 fatty acid (O3FA), on the other hand, is an antioxidant with the ability to improve fertility indices. However, no study has explored the possible ameliorative effect of O3FA on BPF-induced sexual dysfunction. Thus, the effect of BPF and/or O3FA on male sexual performance was investigated. Male Wistar rats were randomized into 6 groups, corn oil-treated, O3FA low and high dose (100 and 300 mg/kg), BPF-treated, BPF + O3FA low and BPF + O3FA high dose. BPF significantly impaired male sexual competence, evidenced by a reduction in motivation to mate, prolonged mount, intromission and ejaculation latency, and post-ejaculatory index. Furthermore, a reduction in mount, intromission, and ejaculation frequency were observed. Also, BPF caused a decrease in gonadotropin releasing hormone, follicle stimulating hormone, luteinizing hormone, testosterone, nitric oxide (NO) cyclic guanosine monophosphate (cGMP), 3beta-hydroxysteroid dehydrogenase (3β-HSD), 17beta-hydroxysteroid dehydrogenase (17β-HSD), dopamine, and acetylcholine esterase. Furthermore, it was accompanied by a significant increase in prolactin and estrogen and poor pregnancy outcomes. These observed BPF-led alterations were abolished by O3FA administration. This study showed that O3FA ameliorates BPF-induced sexual dysfunction by upregulating NO/cGMP signaling and steroidogenic enzymes activities.
双酚 F(BPF)是一种环境污染物,与性功能障碍有关。另一方面,ω-3 脂肪酸(O3FA)是一种具有改善生育指数能力的抗氧化剂。然而,尚无研究探讨 O3FA 对 BPF 诱导的性功能障碍的可能改善作用。因此,研究了 O3FA 对 BPF 诱导的性功能障碍的可能改善作用。将雄性 Wistar 大鼠随机分为 6 组,玉米油处理组、O3FA 低剂量和高剂量(100 和 300mg/kg)、BPF 处理组、BPF+O3FA 低剂量和 BPF+O3FA 高剂量。BPF 显著损害雄性性能力,表现为交配动机降低、交配、插入和射精潜伏期延长,以及射精后指数降低。此外,还观察到交配、插入和射精频率减少。此外,BPF 还导致促性腺激素释放激素、卵泡刺激素、黄体生成素、睾丸激素、一氧化氮(NO)环鸟苷单磷酸(cGMP)、3β-羟类固醇脱氢酶(3β-HSD)、17β-羟类固醇脱氢酶(17β-HSD)、多巴胺和乙酰胆碱酯酶减少。此外,催乳素和雌激素显著增加,妊娠结局不佳。这些观察到的 BPF 引起的改变在 O3FA 给药后被消除。这项研究表明,O3FA 通过上调 NO/cGMP 信号转导和类固醇生成酶活性来改善 BPF 诱导的性功能障碍。
