The topic was highlighted this week in the How To Do It sexual advice podcast by Slate, in which a man got in contact to say that he had lost "about an inch and a half" of length from his penis after catching COVID.
Charles Welliver, a men's health specialist and urologist at Albany Medical College, said on the How To Do It podcast that COVID has been linked to erectile dysfunction, which itself is linked to a decrease in penis size.
This relates to the penis and erections because erections are blood flow events.
A May 2021 study on COVID and erectile dysfunction published in The World Journal of Men's Health concluded that it had found evidence of COVID-19 in the human penis long after the initial infection had occurred, and suggested that the virus' effect on blood flow in the penis could result in impaired erectile function.
