Mirena is a hormone-releasing IUD that is over 99% effective at preventing pregnancy for up to 5 years. Mirena can be used whether or not you have had a child. This contraceptive also treats heavy periods in women who choose intrauterine contraception.
Mirena works in several ways:
1. It inhabits the sperm from reaching/fertilizing the egg.
2. Thins the uterine lining.
3. Thickens cervical mucus to prevent sperm from entering the uterus.
4. Unlike all other types of hormonal birth control, Mirena does not completely shut down ovulation and hormone production. Remember, ovulation is beneficial because it’s the only way to make estradiol and progesterone.
5. Compared to Pills and implants, it delivers a lower dose of progestin, meaning that the side effects are much less.
This is one contraceptive you don’t have to think about taking every day or even every year. Once it’s placed, just do a monthly thread check to make sure it’s in the correct position. This could be something to consider for busy women and moms.
