Male coronavirus survivors are being urged to give blood because of evidence that men produce more antibodies, which could make their plasma a more valuable treatment.
The research, by NHS Blood and Transplant （NHSBT）, suggests men may hold the key in the battle against the virus.
Health chiefs are urging men who have had Covid-19 to come forward and donate blood as part of a national trial to see whether donations can boost the survival of the sickest patients.
Their research shows that 43 percent of male donors had blood plasma rich enough in antibodies, compared with 29 percent of women.
Men with Covid-19 tend to produce more antibodies than women with the virus because men are more likely to become seriously ill.
