The transdermal contraceptive patch releases estrogen and progestin directly into the skin. It is the size of a half-dollar and it can be put on the arm, abdomen, or buttocks. Each patch has a week's worth of hormones. They already contain spermicide so you wouldn't need to use extra spermicide like you do with the regular diaphragm. One diaphragm could provide protection for up to 24 hours.
Vaginal rings are rings shaped like doughnuts.
They contain either estrogen and progestin or just progestin. The rings with just the progestin could be stay in the vagina for several months, and the rings with both hormones could be kept in place for 3 weeks. A woman does not need to be fitted for a ring by a health care provider. A woman could remove and insert the ring herself. The contraceptive vaccine would work by not allowing sperm to bind to the egg and fertilize it or by killing or paralyzing sperm.
