How did prostitutes prevent pregnancy in the old west?
bazaltina [42]

Hello, that is a very good question!


Back then there was no such thing as 'birth-control', hence they never actually prevented pregnancies, of course there were services that provided 'different' penetration but that could also result in pregnancies.


The popular method of not giving birth [prevent pregnancy] was to kill the baby while still carrying [termination], in other words have a miscarriage.

There many various methods during that time (herbs, beating, old cloth hanger).


Hope this helped,
