Covid can damage testicles and reduce libido: HKU study


Research from the University of Hong Kong indicates that Covid-19 could damage the testicles and lead to low libido and reduced fertility.

A team of microbiologists led by Professor Yuen Kwok-yung based the findings on a study of testicular and hormonal changes in hamsters infected with the coronavirus.

The infected hamsters suffered from an acute decrease in sperm count and serum testosterone, which is a male sex hormone, the researchers said. They said the hamsters’ testicles also got smaller and lighter.

From seven to 120 days after infection, inflammation, degeneration and death of testicular tissue persisted, according to the research.

Research has also shown that the Omicron and Delta variants can cause such damage.

The team noted that in some previous studies, some male Covid-19 patients reported testicular pain, while an autopsy study of men who died of Covid showed testicular inflammation with extensive cell damage. .

“In the care of men recovering from Covid-19, it is important to be aware of possible hypogonadism (low libido) and subfertility. Vaccination against Covid-19 can prevent this complication,” Yuen said.

The study has been accepted for publication in the journal Clinical Infectious Diseases.
