Did they use to use animal intestines for condoms before the advent of rubber?

Well, people have been making and using condoms for hundreds of years.  There’s actually archaeological evidence of a 4,000-year-old banana-leaf condom, found in Mexico.  The people living there likely used it for contraception.  Rubber was discovered in the 1740s, and it was used for condoms right away.  Condoms made out of other materials were still used for a long time, though, such as sheep gut, which was often called sheepskin.  Eventually though, only condoms made out of latex rubber would become common, and be what we think of when we think of a “condom”.

I didn't know rubber had been around for so long. Sheep gut, eh?
user
That was long before I was born, it was 1839 or so when the discovery was made.  A good place to learn more about how latex was first discovered is The Birth of Rubber.

Aren't some people allergic to latex?
user
Yeah, in fact there are different types of latex, some of which are less allergenic than others.  There are also condoms made of polyurethane, for example.  Do you know someone who’s allergic to latex, so you’re curious about what else they could use?

Some people are.  In those cases, polyurethane condoms are a good option.  There are plenty of options out there, you’re not limited to latex, and we can look into them if you’d like.
