According to the Tampa Bay Times, sponges with spermicide have been used as a contraceptive device for thousands of years as far back as ancient Egypt.

The major difference between then and now was the spermicide commonly in use. The Egytians used honey and crocodile dung! Some sponges were soaked in lemon juice and guess what, lemon is a somewhat effective spermicide!

Another ancient device for preventing pregnancy involved checking a woman's cervical mucus to determine when she was ovulating. This ancient kit contained a tube, a mirror and a little lightbulb. Need I say more? It was used in the 1960s!! But, according to the publication, this proved ineffective since the changes in cervical mucus are microscopic.
