None. Male honeybees are called 'drones' and they appear in the colony in late spring.
The life cycle of all insects, including honey bees, begins with eggs. During the winter season, a queen forms a new colony by laying eggs within each cell inside a honeycomb. Fertilized eggs will hatch into female worker bees, while unfertilized eggs will become drones or honey bee males. Drones are larger than workers, but smaller than queen honey bees.
As per Aces.uiuc.edu, no certain number is produced and colonies may have only a few hundred or as many as several thousand. They help to produce heat in the colony and may be of value by affecting the "morale" of the colony or in other ways that are still not known. However, since they consume food and take up space, their numbers should be kept at a minimum.
