Monocyte Breeder

 is a type of implant in Fallout: New Vegas.

Characteristics
It causes your character to regenerate hit points at a rate of 1 HP for every 10 seconds. This effect is permanent. This bonus is so small for the cost that it may seem worthless in Normal mode, as by the time the Courier has amassed 12000 caps he or she will usually be well into the game. Although, it is a good perk to have if you wait while not near a bed. In Hardcore Mode, however, sleeping on a bed you do not own (or did not rent) does not heal the player, and thus consumables are the only source of healing; with this perk sleeping and waiting will heal based on the equivalent in real-world seconds to the in-game time passed (Confirmed XBOX, PS3). Fast-traveling will also heal the player for the estimated amount of game-time that the player travels through. Therefore, the healing rate is almost instantaneous, save for the loading sequences between each fast-travel.

On the other hand, since it takes so long to fully heal the player, this effect is only valuable outside of battle. Carrying a few Nuka-Colas or Sunset Sarsaparillas (which heal 50 points of damage over time) and using those between battles can achieve a similar effect. If you have limited endurance points (or caps) and you have to decide which implants you ultimately want your character to have, this may be one of the least useful, even in Hardcore mode.
