Contraceptive Vaginal Ring
The Contraceptive Vaginal Ring (pronunciation: /kɒnˈtræsɪptɪv 'vædʒɪnəl rɪŋ/), also known as the Birth Control Ring or by its brand name, NuvaRing, is a flexible, plastic ring that is inserted into the vagina to prevent pregnancy.
Etymology
The term "contraceptive" is derived from the Latin words "contra", meaning "against", and "conceptus", meaning "conception". The term "vaginal" is derived from the Latin word "vagina", which means "sheath" or "scabbard". The term "ring" is derived from the Old English word "hring", meaning "circle" or "band".
Usage
The Contraceptive Vaginal Ring is inserted into the vagina and left in place for three weeks at a time. It releases a continuous dose of the hormones estrogen and progestin, which prevent ovulation (the release of an egg from the ovaries). The ring also thickens the cervical mucus, making it harder for sperm to reach the egg.
