Tadalafil Femalefil has been studied for its potential effects on female sexual dysfunction (FSD), particularly in postmenopausal women or women with sexual arousal disorders. Some studies have shown that it may help increase sexual arousal, lubrication, and overall satisfaction by enhancing blood flow to the genital area, which may improve sensitivity and response during sexual activity. However, FDA approval for tadalafil to treat female sexual dysfunction has not been granted, so its use for this purpose remains off-label.
