An 82-year-old man experiencing erectile dysfunction, despite being prescribed 10 mg of tadalafil by his general practitioner, has sought advice regarding potential treatment options. The man is in a relationship with a sexually active 72-year-old woman and reports that the medication, which is intended to improve blood flow to the penis, has not been effective. He also disclosed a history of high blood pressure and extensive radiotherapy treatment for prostate cancer a decade ago.

Medical experts note that erectile dysfunction (ED) is common among older men, with research indicating that nearly 80% of men at age 80 experience some degree of ED. Additionally, approximately half of those who undergo standard radiotherapy for prostate cancer—where high-energy radiation targets cancerous cells in the prostate—develop erectile difficulties as a side effect.

The patient’s current blood pressure medication may also contribute to erection problems, and the combined factors of age and cancer treatment history complicate management. Despite the patient’s inquiry about escalating the dose of tadalafil or pursuing testosterone replacement therapy (TRT), specialists caution against these approaches. They highlight that increasing the medication dosage is unlikely to yield better results, and prescribing TRT carries the risk of reactivating any dormant prostate cancer cells that may have survived prior treatment.

Alternative treatment modalities recommended include the use of a vacuum erection device or a penile implant. Vacuum pumps create negative pressure around the penis using a clear cylinder and pump mechanism, encouraging blood flow into erectile tissue. Following the vacuum application, a constriction ring is placed to maintain the erection for a limited period, typically sufficient for sexual activity. This method is considered safe, does not rely on hormone levels, and is often acceptable to couples.

In contrast, penile implants involve surgical insertion of a device to simulate permanent erections. Although effective, implants typically result in a continuous erection state, which may not be ideal for all patients.

Separately, a patient who has suffered from recurrent diverticulitis for years reports symptom relief after starting probiotics. Diverticulitis is characterized by inflammation or infection of small pouches, known as diverticula, that develop in the intestinal wall. The condition can cause abdominal pain, bleeding, and in severe cases, infection leading to complications such as abscess formation, peritonitis, or sepsis.

Conventional treatment includes rest, intravenous fluids, and antibiotics targeting bacterial infection. Surgery may be necessary if complications arise. While the precise mechanism by which probiotics might prevent diverticulitis flare-ups remains unclear, some studies have shown a reduction in inflammation markers among patients taking probiotics during acute episodes. It is proposed that probiotics help restore balance to the intestinal microbiome, increasing beneficial bacteria that may suppress harmful pathogens.

Though evidence supporting probiotics’ efficacy in preventing diverticulitis is limited, clinicians often recommend them as a complementary measure, especially when patients report symptomatic improvement.
