Sperm is a precious resource

Humanity was facing a crisis of survival that struck without warning. When it began males were no longer being born into the world. The phenomenon occurred simultaneously across the planet and global population fell rapidly over several decades. Researchers united to find the cause but no one could determine a clear cut answer. The sudden onset of an existential crisis sent the world into chaos. Eventually the community settled on a theory that due to repeated atrocities like environmental destruction and war the human genome spontaneously decided to end its own existence. The wide spread acceptance of such an occult theory was an indication of the chaotic state of the world at that time. But there has always been exceptions. And despite the fact that birthrates have dropped year after year there remains a 0.5% chance that a male is born. In many countries a law was made that binds a boy from the moment he is born. A law enacted to protect the human species. A simple law that can be summed up in one word—BREED. Women who are able to conceive were special collars to indicate that they are fertile. A woman who desires a baby needs to go to the government, and have official examinations and bloodwork at a clinic to ensure they are capable of having a child and that there are no risks of complications. Once approved and given a collar they are required by law to always wear it except for times such as menstruation and pregnancy. A collared woman can be taken at anytime in any place by a man.
