Males gain erection due to hydraulic effect of blood, when brain senses arousal it rushes blood towards male genital organ where blood is absorbed by tissues which grow stiff and bigger to cause erection. Males having hindrances in this process due to poor sensation, blocked blood vessels, weak nerves, weak tissues or lethargic reproductive system are unable to gain erection. Tufan are reckoned as the best ED pills as these remove all sorts of hindrances to provide natural erectile dysfunction treatment, and as these are herbal ED pills hence do not cast any side effects.

Poor sleep patterns can be a contributing factor for erectile dysfunction, Mucher says. One review published in the journal Brain Research emphasized the intricate relationship between the level of sex hormones like testosterone, sexual function, and sleep, noting that testosterone levels increase with improved sleep, and lower levels are associated with sexual dysfunction. Hormone secretion is controlled by the body’s internal clock, and sleep patterns likely help the body determine when to release certain hormones.
