Since the novel coronavirus outbreak, scientists have been developing an understanding of how novel coronavirus affects the human body and how it can be transmitted from person to person.In recent months, scientists have learned that the virus can live for up to three days on some surfaces and can stay in tiny droplets for about 30 minutes. It has also been detected in human saliva, urine and feces.
Now, a team of Chinese researchers has found a novel coronavirus in the semen of infected people, raising the possibility that the virus could be transmitted sexually.Novel coronavirus was detected in semen for the first time, according to a study published Thursday (May 7) in JAMA Network Open, a journal of the American medical association.
Novel coronavirus viruses cannot be proved to be sexually transmitted, the paper said.At the same time, the details of novel coronavirus shedding, survival time, concentration in semen, etc., remain to be further studied.

The study shows that the Chinese people’s liberation army general hospital south tower respiratory kidney disease (CKD), the people’s liberation army, the people’s liberation army general hospital kidney research institute, Beijing chaoyang hospital, henan shangqiu city hospital team of experts in henan shangqiu city hospital 38 male semen of infected were tested, and all the participants were aged 15 to 59 years old, and after will be coronavirus detection was positive.Of these, 23 patients were in recovery and the remaining 15 were in the acute phase of infection.
The Chinese team’s paper was published Thursday in JAMA Network Open, a journal of the American medical association.
The researchers detected genetic material from novel coronavirus in the semen of six of the patients, about 16 percent.Four of the patients with positive semen samples were in the acute phase of covid-19 infection, the paper noted.In particular, two other patients who tested positive for the virus are recovering.According to the charts in the paper, one of the men had been clinically rehabilitated for three days.
However, the researchers noted that the study had a small sample size and short follow-up time.Therefore, the details of novel coronavirus shedding, survival time, concentration in semen, etc., need to be further studied.
Two patients who tested positive for the virus were in recovery, the paper showed.
Since the beginning of the outbreak, public health experts have said that while novel coronavirus can be transmitted by kissing, they do not believe it can be transmitted sexually.This new finding does not contradict this.Notably, although genetic material from novel coronavirus was detected in semen, the study does not prove that the virus particles are “alive” or capable of spreading infection, the New York times said.
Medical experts said the study was preliminary and left many questions unanswered, such as how much viral load is in sperm and whether the virus can be transmitted through sex.It is also unclear how long the novel coronavirus stayed in the semen, because the patients in the study still had symptoms or had only recently recovered.
Liona Poon, a professor of obstetrics and gynecology at the Chinese university of Hong Kong, told the Wall Street journal that the study did not indicate how much viral load was in semen, whether it was viral fragments or intact virus particles.And it is not known for sure if the virus is contagious until it is isolated and cultured.
Dr. Stanley perlman, a professor of microbiology, immunology and pediatrics at the university of Iowa, also said a positive semen test for novel coronavirus does not indicate the presence of an infectious virus.”This is an interesting finding, but it must be confirmed that there are infectious viruses in semen, not just viral RNA,” he said.
Unlike zika, which is carried in the blood, novel coronavirus infects humans primarily through the mouth or nose, he added.At this time, there is still no evidence that a person may contract novel coronavirus through sexual contact or intrauterine insemination.
