Fildena CT 100 is a form of sildenafil citrate (the same active ingredient as in Viagra) that is used to treat erectile dysfunction (ED). It’s a chewable tablet (hence the "CT" in the name) that is designed to be taken before sexual activity to help men achieve and maintain an erection by increasing blood flow to the penis. How Fildena CT 100 Affects Men with Low Testosterone While Fildena CT 100 can be effective in treating erectile dysfunction, it primarily addresses the physical aspect of ED — specifically, improving blood flow to the penis. It does not directly impact testosterone levels. However, here's how it can affect men with low testosterone: Short-Term Improvement in Erectile Function: Testosterone plays a key role in sexual drive (libido) and overall sexual function, but erectile function itself is more closely tied to the vascular system (blood flow). Fildena CT 100, like other sildenafil-based medications, can help improve the ability to get and maintain an erection regardless of testosterone levels, as long as the cause of the ED is related to blood flow. If a man with low testosterone is experiencing ED due to issues with blood flow (e.g., poor circulation, vascular problems), Fildena CT 100 can be an effective treatment. Does Not Treat Low Testosterone: Fildena CT 100 will not increase testosterone levels. If a man has low testosterone levels that are contributing to low libido, fatigue, or other symptoms, testosterone replacement therapy (TRT) or other forms of treatment may be needed to address the root cause. While sildenafil-based medications can help with erections, they do not influence testosterone production or its effects on overall sexual desire or energy levels.
