Low Sperm Rate Associated With Cancer Risk
Men who are diagnosed as having no measurable level of sperm before the age of 30 have a higher risk of developing cancer than the general population, according to a study led by Stanford University School of Medicine. A diagnosis of azoospermia before 30 carries an eight-fold cancer risk, the study says. Researchers surmise that infertility could be a barometer for future health. Azoospermia is caused by either a blockage that obstructs sperm from reaching the ejaculate or because the testes don’t produce enough sperm. Most cases of azoospermia occur from the latter cause.
