Fildena 120 mg, which contains Sildenafil Citrate (the same active ingredient in Viagra), is primarily used to treat erectile dysfunction (ED). It works by increasing blood flow to the *****, allowing men to achieve and maintain an erection during ***** activity. However, whether Fildena 120 mg helps with morning erections (known as nocturnal penile tumescence, or NPT) is a bit more complex. Morning Erections (Nocturnal Penile Tumescence - NPT): Morning erections are normal physiological occurrences in healthy men. They typically happen during the REM (Rapid Eye Movement) phase of sleep and are thought to be the body’s way of ensuring proper blood flow to the *****. These erections can occur even without any ***** stimulation and are a sign of good erectile function. Fildena 120 mg is designed to help men with ED by improving blood flow during ***** arousal, but it does not specifically target morning erections. Here’s why: How Fildena 120 mg Works: Sildenafil (the active ingredient in Fildena 120 mg) works by inhibiting the enzyme PDE5, which normally breaks down a molecule called cGMP that is responsible for dilating blood vessels in the *****. During ***** arousal, increased levels of cGMP allow more blood to flow into the *****, helping men with ED achieve an erection. However, Fildena 120 mg (or any sildenafil-based drug) is taken in response to ***** activity and requires ***** stimulation to work. It does not directly influence spontaneous or involuntary erections like morning erections, which occur without ***** arousal. Morning Erections and ED: Healthy men typically have morning erections as a natural process.
