Many urologists and sexual health specialists do prescribe PDE5 inhibitors like Fildena 50 after surgeries that may lead to ED. This form of penile rehabilitation aims to restore blood flow early to the penile tissue, which may prevent long-term damage and help men regain natural erectile function over time. However, its effectiveness often depends on the nature and extent of surgical damage. If the nerves responsible for erections have been completely removed or severely damaged, Fildena may have limited benefit. Conversely, if the nerves are intact but temporarily impaired, Fildena could aid in recovery by promoting better circulation and supporting erectile response.
