No mention of hot-water-boarding the old baby-batter-boys? Back in the day a man would plunge the his yarbles into very hot water before a bit of the old in-out, in-out in order to avoid crotch-fruit. Since the testes need to be a few degrees below body core temp for optimized tadpole production (that's why they hang, guys & gals) this is crude but *somewhat* effective means of birth control.
To this day, if you're looking to be a new daddy the preggers doc will tell you to avoid hot baths before romance.
Many of us owe are very existence to bad contraception concepts. I for one am thankful for the Catholic Church, for their very lack of practical contraception advise that ended up with my birth.

Lois Griffin: Peter...

I will never have children. Why? Because laws give more rights and benefits to the mother, and I believe that is unfair. I'm thinking about getting a vasectomy so no bitch can ever trick me into paternity and freeload of me for 18 years.
I got a vasectomy. If you don't want kids, DO IT. $500, 10 minutes on the table, 10 days for the soreness and swelling to disappear, and you are a free man. I wish I could have had my vasectomy when I was 16 and knew then I didn't want kids.
