Malegra Professional, which contains sildenafil as its active ingredient, is primarily used to treat erectile dysfunction (ED) by improving blood flow to the penis. It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which helps relax blood vessels and increases blood flow during sexual arousal.

However, Malegra Professional does not have a direct effect on testosterone levels. Testosterone is a hormone produced by the testes in men and is primarily involved in regulating sexual desire, energy, and muscle mass. Sildenafil (the active ingredient in Malegra Professional) does not influence testosterone production or secretion, and it doesn't alter hormone levels in the body.

If you're concerned about low testosterone or its impact on sexual health, it's best to consult with a healthcare provider who can assess your hormone levels and suggest appropriate treatment.
