Don't rely on this: as a contraceptive. The sperm count does not necessarily change and does not necessarily go down enough to lower fertility (mostly requiring 50-90% reduction to matter at all, and then, isn't totally infertile, just Less fertile). Under a week. http://news.nationalgeographic.com/news/2010/03/100318-men-sperm-1500-stem-cells-second-male-birth-control/
