Contraceptive Ring

The contraceptive ring is a small, flexible plastic ring, which you insert into your vagina, where it releases 2 hormones, oestrogen & progestogen. It stops ovulation, thickens cervical mucus to stop sperm reaching an egg, & thins the lining of the uterus to stop a fertilised egg implanting. 

It is over 99% effective if always used according to instructions (perfect use); with fewer than 1 in 100 ring users getting pregnant in a year. With typical use, it is around 91% effective; with around 9 in 100 users getting pregnant in a year.


Contraceptive Ring SyreniRing

Both brands contain the same active hormones and work in the same way. The main difference is in the length of time the contraceptive ring can be prescribed for: SyreniRing can be prescribed for up to 3, 6 or 12 months; and NuvaRing can be prescribed 3 months at a time.
