I can give more of an answer. There is (or was) a birth control method called the sponge, or the today sponge. It is entered into the vagina and pushed up against the cervix, blocking the entrance, and it contains spermicide as well.
In s7e9 of Seinfeld, the sponge is discontinued, causing Elaine to panic (as it is her preferred method of birth control) and search across the city to find more sponges. When she does find and buys a case, she then realizes that even though she has more sponges, she may never be able to get more, and thus starts to debate on whether her current boyfriend is “sponge worthy”
