New Study Reveals Surprising Health Perk of Viagra for Seniors

Viagra May Help Strengthen Bones in Older Adults, Study Finds.

Best known for treating erectile dysfunction, Viagra may soon have a surprising new role in healthcare — as a potential treatment for osteoporosis. A study published in April 2025 on PubMed by researchers from Peking University suggests that sildenafil, the active ingredient in Viagra, may help strengthen bones in older adults.

A Surprising Discovery
According to the research, sildenafil can encourage human stem cells to develop into osteoblasts — the cells responsible for forming new bone tissue. This finding opens the door to repurposing the drug to help combat osteoporosis, a condition that causes bones to become weak, brittle, and prone to fractures as people age.

What It Could Mean
As people grow older, the body tends to break down more bone than it creates, increasing the risk of painful and potentially debilitating bone conditions. Current treatments for osteoporosis do exist, but researchers argue there’s a need for more affordable and widely available options.

“Sildenafil enhanced stem cell osteogenic differentiation and inhibited bone loss — it may usefully treat osteoporosis,” said Dr. Menglong Hu and Dr. Likun Wu, members of the Peking University research team.

A Readily Available Option
One advantage of sildenafil is its existing approval and safety profile. “Any new drug must be evaluated. This is time-consuming, expensive, and risky,” the researchers explained. “But sildenafil is approved and safe.”

If further research supports these findings, Viagra could offer a cost-effective and accessible alternative for treating osteoporosis in aging populations.
