Viagra (Sildenafil 50 mg) is commonly used to help men with erectile dysfunction achieve and maintain an erection sufficient for sexual activity.

• Effect on Duration: It does not directly increase the total duration of sexual intercourse or the time from start to finish. Instead, it helps improve the ability to get and keep an erection.

• How it works: Sildenafil works by increasing blood flow to the penis when sexually stimulated, which helps in achieving an erection.

• Important to note: It does not increase sexual desire or delay ejaculation.

• Usage: The effect usually lasts for about 4 to 6 hours after taking the pill.

If you have concerns about sexual performance or duration, it is best to discuss them with a urologist who can offer personalized advice and check for any underlying conditions that might affect sexual health.
