When the Mondus was created, time god Akatosh, from only he knows what created two first Dragons and then some more. The first two was Alduin and his little brother Paxthy. So the two of them and all those that were created later existed ever since then. They are immortal to the normal means, if someone mannages to kill them, they will only slumber in skeletal form, until their soul can return to their bodies. They and Dragonborn are the only ones that can permanantly kill each other.

Think of it as all Dragons were created all at once and always existed. So, there is no need for them to reproduce, so the probably laking any genitalia weather male or female. Technically they are all males. However, there is a totaly different question, how much of male genitalia they are missing? They might not reproduce, but how do they do their *ahem* little business?
