how long can sperm live inside you
A lot of numbers are thrown out there about the life span of sperm. Here's the scoop: Sperm can live as little as one or two hours or as long as 5 or 6 days--it all depends on their environment. Outside the vagina, sperm only lives until it dries out. Once inside the vagina, the lifespan of the sperm is heavily dependent on the woman's vagina, uterus, and fallopian tubes. Without fertile cervical fluid, sperm live at most for a few hours inside the vagina or uterus (if they make it that far).
