Ivermectin causes 'sterility' in 85% of males who take it: study
Far-right extremists and conspiracy theorists, many of them anti-vaxxers, have been falsely claiming that Ivermectin — an antiparasitic drug typically given to animals — can be used to prevent or treat COVID-19. The U.S. Food and Drug Administration, in response, has been warning Americans that taking animal-grade Ivermectin can be "highly dangerous." And the effects of Ivermectin on people have been studied in Nigeria, where researchers found that taking it is likely to cause sterility in men.
Erin Coulehan, a reporter for WFLA-TV (an NBC affiliate in Tampa, Florida), explains, "The effects of Ivermectin therapy on human males can have an effect on men's reproductive health. Researchers at three universities in Nigeria studied the effects of Ivermectin, which is used to treat river blindness and other medical conditions in humans, on men's sperm counts. According to their study, 85% of men who take Ivermectin become sterilized."
Coulehan adds, "Ivermectin is often used as an anthelmintic to combat parasites in animals, and some people have been using it to fight COVID-19 despite health experts' recommendations against it. The study conducted by researchers in Nigeria screened 385 patients with river blindness to investigate the effects of Ivermectin on sperm function; the researchers found that 85% of all male patients treated in a particular center with Ivermectin in the recent past who went to the laboratory for routine tests were discovered to have developed various forms, grades and degrees of sperm dysfunction."
