Professor Yuen Kwok Yung led the study on testicular and hormonal changes in hamsters infected with the coronavirus.Researchers from the University of Hong Kong have found that the coronavirus could damage testicles, lower sex drive and affect fertility in men.
The infected hamsters suffered from a sharp drop in sperm count and serum testosterone, a male sex hormone, four to seven days after infection. Acute testicular inflammation, haemorrhage, and death of tissue in the sperm cell-producing seminiferous tubules and disruption of spermatogenesis, a process of sperm cell development, were also detected.
