Contraception has become very important for today's sexually active women. There has been the introduction of various innovative forms of contraception which gives you a respite from taking contraceptive pills every day for 21 days in a row. At times, it becomes tedious for women to take a pill every day, especially in today's busy professional world. This has led to the development of an effective ring called NuvaRing. It is a small and flexible ring which is inserted into the vagina once a month. It is about two inches in diameter and supplies your body with artificial versions of progestogen and oestrogen.
The hormone is released directly into your blood stream. The artificial oestrogen is called ethinylestradiol and the synthetic progestogen is known as etonogestrel. These two hormones work in three ways to prevent you from falling pregnant. First, it makes the body believe that ovulation has already occurred. This prevents ovulation and thus there will be no release of eggs from ovaries. Second, it makes the cervical mucus viscous enough for a sperm to be unable to enter inside the womb. Finally, it alters the womb lining due to which an egg, if it gets fertilised, fails to attach itself and grow in the womb.
