Etonogestrel is a medication which is used as a means of birth control for women. [4] [5] [12] [13] It is available as an implant placed under the skin of the upper arm under the brand names Nexplanon and Implanon.
Trussell did not use 1995 NSFG failure rates as typical use failure rates for the other two then newly available long-acting contraceptives, the Norplant implant (2.3%) and the ParaGard copper T 380A IUD (3.7%), which were (as with DMPA) an order of magnitude higher than in clinical trials. Since Norplant and ParaGard allow no scope for user ...
It works by reducing the frequency of the pill-free or placebo days. Extended cycle use of COCPs may also be called menstrual suppression, [2] although other hormonal medications or medication delivery systems (hormonal intrauterine devices—IUDs) may also be used to suppress menses. Any brand of combined oral contraceptive pills can be used ...
LARC failure rates are comparable to those of sterilization. [15] LARCs and sterilization differ in their reversibility. The implant has a 0.05% failure rate in the first year of use, the levonorgestrel (hormonal) IUD has a 0.1% failure rate in the first year of use, and the copper IUD has a 0.8% failure rate in first year of use.

A contraceptive implant is an implantable medical device used for the purpose of birth control. The implant may depend on the timed release of hormones to hinder ovulation or sperm development, the ability of copper to act as a natural spermicide within the uterus , or it may work using a non-hormonal, physical blocking mechanism.
The FDA first approved the oral contraceptive in 1960. The first oral contraceptive contained 100 to 175 μg of estrogen and 10 mg of progesterone. However, at these levels significant adverse effects were seen and modern preparations contain lower levels of 30 to 50 μg of estrogen and 0.3 to 1 mg of progesterone. [49]
It needs to be fitted by a medical professional. It has a failure rate of 17%. [1] A contraceptive sponge is another contraceptive method. Like the diaphragm, the contraceptive sponge contains spermicide and is inserted into the vagina and placed over the cervix to prevent sperm from entering the uterus. The sponge must be kept in place 6 hours ...
A 2006 study of 124 premenopausal women measured sex hormone-binding globulin (SHBG), including before and after discontinuation of the oral contraceptive pill. Women continuing use of oral contraceptives had SHBG levels four times higher than those who never used it, and levels remained elevated even in the group that had discontinued its use.
