Birth Methods:

Borg are not born they are assimilated

Assimilation into the Collective begins when the skin of an organic creature is penetrated by the delivery tubules which extend from the fingers of each Borg drone

These tubules deliver nanites into the bloodstream which rapidly begin to assimilate the red blood cells. This first stage of assimilation is rapidly followed by the addition of specific cybernetic devices to the physiology of the organism. According to some sources, this stage of assimilation is overseen by the Borg queen, however, the sheer number of assimilated organisms makes such reports seem dubious

The nature of the cybernetic devices linking the Borg drones facilitates the creation of the Borg Collective Consciousness.
