A lot if you are a primitive person who breeds like some other less intelligent species. Then you produce a lot more children then the educated, civilized person.
If you behave like an intact house-cat or domesticated dog who is unable to handle family planning, you need to be treated in the same manner. These people need to be spayed and neutered due to their inability to handle birth control like normal, civilized people.
There is an option for people who want large families, it's called adoption. Have a good home and extra income for another child?...adopt one in need. There is no need to be irresponsible and add to the world's overpopulation problems by acting like an intact house-cat.
The solutions are already here, now some people need to use them.
