"Slut mothers" can only bear one child in a nine month period, with the exception of twins or more. Slut fathers on the other hand can impregnate any number of women in the same time frame. Let's heap some shame on slut fathers.
I mentioned the solution, which includes socially chastising both females and males. No government resolution is necessary.
As for the extra measure, since males completely escape the physical birthing process and the pain associated with raising illegitimate children, they will need to be indebted for life... making stiff child support payment (a fixed amount that accounts for social costs of out-of-wedlock children, rather than a minuscule portion from their paycheck). In no time they will be in the streets, which should serve as a notice to future deadbeats.
