Typically, millions of sperm cells are produced in the testicles every day. During this time, the cells that make up the sperm divide and change. The sperm cells make their way into the epididymis where they finish developing, which can take several weeks. The sperm eventually develops a head and tail, so that it cells start to resemble a tadpole. The head contains all of the DNA or genetic material, and the sperm uses the tail to help it move.

If a man has any of these risk factors, he should try to change them at least months before trying to conceive, since that is how long it takes for sperm to fully mature. Reducing the above risk factors whenever possible helps to keep sperm cells healthy, especially before conception. Sperm live outside the body for different lengths of time, depending on the environment in which they were released.
