Combined contraceptive patch and combined contraceptive vaginal ring (CVR)

Vaginal ring

Continuously releases 2 hormones – a progestin and an estrogen- directly through the skin (patch) or from the ring.

How it works: 
Prevents the release of eggs from the ovaries (ovulation)
Effectiveness to prevent pregnancy: 
The patch and the CVR are new and research on effectiveness is limited. Effectiveness studies report that it may be more effective than the COCs, both as commonly and consistent or correct use.
Comments: 
The Patch and the CVR provide a comparable safety and pharmacokinetic profile to COCs with similar hormone formulations.
