Sildigra is a brand name for sildenafil citrate, which is a medication commonly used to treat erectile dysfunction (ED). Sildenafil works by increasing blood flow to the penis, helping to achieve and maintain an erection in response to sexual stimulation. It's similar to Viagra, which also contains sildenafil.
Sildigra inhibits an enzyme called phosphodiesterase type 5 (PDE5), which can restrict blood flow to the penis. By blocking PDE5, Sildigra allows more blood to flow into the penis when you’re sexually aroused. If you're asking whether Sildigra itself causes an erection or "hardening," the answer is that it helps make it easier to achieve an erection if you’re sexually stimulated. However, it does not automatically lead to an erection without arousal.
