Testosterone injections can render men temporarily infertile and function as a male contraceptive, Chinese scientists say. Their tests on 1,045 healthy, fertile men were 99% successful and left only two subjects less fertile than they were before the trial. “Our study shows a male hormonal contraceptive regimen may be a potential, novel and workable alternative,” one researcher told the Telegraph.
But one Western expert expressed doubts about the study: “This new formulation appears to be a success,” she said. “However, hormonal male contraceptives seem to work differently in Chinese and Caucasian men.” The search for a male pill has been slow, partly because Big Pharma lacks interest and because of a belief that women won't trust men to play it safe.
