Malegra 25 mg (sildenafil) does not protect against STDs because of how it works. Here’s a detailed explanation  Mechanism of Malegra Active ingredient: Sildenafil Function: Sildenafil is a PDE‑5 inhibitor. It works by increasing blood flow to the penis, helping achieve and maintain an erection when sexually stimulated. It does not affect viruses, bacteria, or other pathogens that cause sexually transmitted infections   Why It Doesn’t Protect Against STDs STDs are caused by microorganisms like HIV, chlamydia, gonorrhea, Malegra 25 mg , or herpes. Protection against these requires barriers or medications, such as: Condoms (male or female) Pre-exposure prophylaxis (PrEP) for HIV Vaccines (e.g., HPV, Hepatitis B) Regular testing and treatment for partners Sildenafil only helps with blood flow and erection, not infection prevention.  Key Takeaway Taking Malegra 25 mg does not prevent STDs or HIV. Safe sex practices like using condoms and getting regular sexual health check-ups are necessary to reduce the risk of infections. If you want, I can make a simple diagram showing what ED medications do vs what protects against STDs, so it’s easier to understand why Malegra doesn’t offer STD protection.
