Sperm can survive on the human hand for a short period, typically a few minutes to a couple of hours, depending on environmental conditions like moisture and temperature. However, their ability to fertilize an egg diminishes significantly once they are outside the body. To minimize any risk of unintended transfer, it's advisable to wash hands thoroughly after contact with semen.
