Dear Hopeless

Sperm in general, remain alive, but are inactive and are stored in various stages of maturity within the male genital tract. It is only when the mature sperm combine with ejaculatory fluid that the sperm become active and start to move and develop fertilisation potential. This usually happens with ejaculation. However, if there has been no ejaculation for a prolonged period of time then an increasing percentage of stored sperm may undergo premature death and may be ejaculated as dead sperm. While the exact interval is not known it is believed that in excess of 7 days without ejaculation the tendency for dead sperm production increases.

I have done a lot of reading on different internet sites and it seems that most sites agree that sperm can survive in the body for up to 5 days. But it is save to rather assume 2 – 3 days to be on the save side.
