Final answer:
Physicians can perform penile implant surgery to improve erectile functioning when other treatments, including medication like Viagra® and Cialis®, are ineffective.
Step-by-step explanation:
The correct answer to the question is B) Penile implant surgery. This medical procedure is considered when other treatments for erectile dysfunction (ED), such as lifestyle changes and prescription drugs known by brand names such as Viagra® and Cialis®, do not provide the desired results. These prescription drugs primarily work by increasing blood flow, which is often the first-line treatment for ED. If these less invasive treatments are ineffective, more invasive approaches like penile implant surgery may be employed.
It is important to note that there can be severe side effects associated with certain treatments for erectile dysfunction, such as ED medications or surgeries. However, these side effects are often specific to the type of treatment used and would need to be discussed in detail with a healthcare professional.
