Darren Logan answered on 22 Mar 2012:
The sperm wiggles its way up into the uterine tube. where it reaches an egg, the acrosome of the sperm (which is a structure at the edge of the head) produces enzymes which allow it to burrow through the outer jelly coat of the egg. The sperm plasma then fuses with the egg’s plasma membrane, the sperm head disconnects from its tail and releases its DNA to meet up with that from the egg.

DNA is the material that makes up all of our genes. We get one set from our father (the sperm) and one from our mother (the egg) and the come together to form us!
