Viagra’s Surprising Health Benefits Extend Beyond Erectile Dysfunction

Viagra, often recognized for its role in treating erectile dysfunction, appears to have a broader range of health benefits than initially thought.

Recent studies are shining a light on unexpected uses of the medication, which could include everything from reversing hearing loss to addressing enlarged prostates. Now, it seems it might even play a role in halting cancer spread.

Despite the medication’s popularity—over 23 million men had used it by 2005—doctors are continually searching for new ways to combat the increasing rates of cancer, which are projected to nearly double by 2050.

Researchers at the Weizmann Institute of Science have recently found that Viagra, specifically its active ingredient sildenafil, may impair the ability of cancer cells to metastasize. Their findings, published in the journal Cancer Research, suggest that sildenafil disrupts the cholesterol supply, a crucial component for cancer cell growth.

The study was led by Dr. Yarden Ariav and Professor Ayelet Erez, who investigated mouse cancer models, human cancer cells, and two decades of medical records from 5 million patients in Israel’s Clalit Health Services.

They discovered that sildenafil seems to limit cancer cells’ ability to utilize cholesterol effectively. It works by blocking the enzyme phosphodiesterase type 5, which subsequently raises cGMP levels—a molecule that increases blood flow but also interferes with cholesterol transport within cells.

This cholesterol limitation is significant because cancer cells, particularly when they detach from a main tumor, rely heavily on it for survival and growth.

Further analysis of medical records indicated that sildenafil was linked to improved survival rates in cancer patients, especially when taken alongside statins, which lower “bad” cholesterol levels. The combination of these medications might effectively starve tumors by cutting off their access to cholesterol.

As Erez pointed out, while genetic mutations within tumors are a major driver of cancer growth, a patient’s overall metabolic state and their existing medications can also shape cancer biology.

Thus, addressing the patient’s whole health—rather than focusing solely on cancer treatment—becomes essential. External factors, including diet, may also influence tumor development. For instance, a high-fat diet has been shown to accelerate tumor growth in some cancers, while rising consumption of ultra-processed foods correlates with increased colorectal cancer rates among younger adults.
