|Intrauterine Devices (IUD/IUS)|

Cons: Recommended principally for women in monogamous relationships. Can be expelled or become dislodged. Not recommended for women with fibroids.
(Copper T) IUD
|ParaGard can stay in place for up to 10 years. Fertility usually resumes immediately when removed. Can be accompanied by an increase in volume and duration of menstrual flow.|
|Mirena can remain in place for 5 years. Possible delay in return of fertility once Mirena IUS is removed. Releases levonorgestrel (LNg), a synthetic progestin, just in the uterus. Reduces menstrual volume eventually, but spotting can occur in initial 6–12 months.May cause benign ovarian cysts.Can rarely cause hormonal side effects similar to those seen with oral birth control pills, such as mood swings, breast tenderness, headaches, and acne.|

|Pros/Cons: Surgical risks. Permanent way to no longer become pregnant. Cost-effective over time.These methods can in some (few) cases be reversed, depending on the method and the individual.|

Birth Control Method Comparison Chart
This comparison chart provides various methods of birth control, along with their reliability factors, pros and cons, and also advantages and disadvantages. This information will give you and your partner knowledge about a variety of conception methods, including intrauterine devices (IUD), hormonal methods (pills, ring, patch, injection, and implant), spermicidal methods, and family awareness methods (rhythm, body temperature, billings, and sympto-thermal).
While these mentioned methods are primarily female related, there are two methods that also include men. These are sterilization (tubal ligation for women and vasectomy for men) and barrier methods (male and female condoms). As a woman, or together as a couple, it is critical for you to be well informed about all available options. This chart is a compilation of currently available choices. It is wise to review the options with your health care practitioner from time to time to determine if the contraception method you are currently using is the best for your healthy lifestyle. I hope this knowledge will empower you.
