Of the 745 women with implants in the original premarket studies, 92% were followed up at one year, and 25% for two years, for safety outcomes. A 2009 review concluded that Essure appeared safe and effective based on short-term studies, that it was less invasive and could be cheaper than laparoscopic bilateral tubal ligation. [2]
Tubal ligation is also known as 'tying tubes'. This is the surgical process where medical professional closes or ties the fallopian tubes in order to prevent sperm from reaching the eggs. This is often done as an outpatient surgical procedure and is effective immediately after it is performed. The failure rate is 0.5%.
The rate of serious complications is comparable to that of myomectomy or hysterectomy. The advantage of somewhat faster recovery time is offset by a higher rate of minor complications and an increased likelihood of requiring surgical intervention within two to five years of the initial procedure.

[6] [7] The most effective methods of birth control are sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs), and implantable birth control. [8] This is followed by a number of hormone-based methods including contraceptive pills, patches, vaginal rings, and injections. [8]
The Pearl Index, also called the Pearl rate, is the most common technique used in clinical trials for reporting the effectiveness of a birth control method. It is a very approximate measure of the number of unintended pregnancies in 100 woman-years of exposure that is simple to calculate, but has a number of methodological deficiencies.
The effectiveness of the copper IUD (failure rate of 0.8%) is comparable to tubal sterilization (failure rate of 0.5%) for the first year. [15] [16] [17] The copper IUD is effective as contraception as soon as it is inserted and loses efficacy when removed or if it becomes malpositioned. [5]
The copolymer is made by irradiation of the two monomers with a dose of 0.2 to 0.24 megarad for every 40 g of copolymer and a dose rate of 30 to 40 rad/s. Dr Pradeep K. Jha, a senior scientist, worked on the effects of gamma dose rate and total dose interrelation on molecular designing and biological function of polymer. [ 10 ]
Trussell's estimated perfect use first-year failure rate for DMPA as the average of failure rates in seven clinical trials at 0.3%. [ 40 ] [ 41 ] It was considered perfect use because the clinical trials measured efficacy during actual use of DMPA defined as being no longer than 14 or 15 weeks after an injection (i.e., no more than 1 or 2 weeks ...
