“…the frameless device performs similarly to the TCu380, and appears to have a lower pregnancy rate in later years, although the absolute difference is small'. 17 The cumulative six-year pregnancy rates were 2.4 per 100 for the Flexigard 1 and 2.8 for the TCu380A, and were not significantly different (p > 0.05).…”

“…Cochrane reviews have also summarised comparisons of framed and unframed IUDs, based on studies including 5,939 women with 23,180 woman-years of experience 17 . The authors observed 'a tendency towards a higher pregnancy rate with the frameless device at one year (RR 1.79, 95% CI 0.81-3.95) to three years (RR 1.34, 95% CI 0.85-2.10)' but during the period of years 2-6, a significant difference in the opposite direction was found, favouring the frameless device (RR 0.53, 95% CI 0.32-0.91).…”

Since the 1959 revival of the IUD, non-hormonal devices have become the most widely used of all reversible contraceptives. Pregnancy rates of copper-releasing IUDs in current use range from approximately 0.5 to 1.5 per hundred continuing users in the first year, with somewhat lower annual pregnancy rates thereafter. Evidence-based research has been systematically conducted and translated into guidelines for eligibility criteria and problem management. Recent device research, beyond the T, Multiload and frameless devices has centred on improved designs such as U ,Y and Slimline shapes, or enhanced copper release, the latter through electrochemical effects or nanotechnology applications. Other IUD research foci concern devices that decrease bleeding and pain by releasing non-steroidal anti-inflammatory drugs. Yet other research lines indicate noncontraceptive benefits of copper intrauterine devices in protecting against endometrial cancer, and favourable risk-benefit analyses of IUD use by women at risk of or post HIV infection. IUD mechanisms of action and the relation of IUDs to pelvic infection and ectopic pregnancy are briefly reviewed. For our literature search we used Medline, Popline and Cochrane Library data bases, Google search, our personal files, and the references contained in articles in our files.

“…It may be particularly useful in a nulliparous woman, or a woman with a small uterine cavity 81 . GyneFix 1 is highly effective, with pregnancy rates similar to those of the Copper T 380 series 80,81,86 . In the UK, it is licensed for 5 years, but data are emerging on its continuing efficacy for up to 10 years 86 .…”

Contraception for the older woman: an update

Although fertility declines with advancing age as the woman approaches the menopause, some risk of pregnancy persists, and effective contraception needs to be offered to avoid an unintended pregnancy. An older woman may have menstrual dysfunction or climacteric symptoms and these factors would need consideration when making the choice of contraception. Low-estrogen dose combined oral contraceptives may be prescribed to healthy non-smoking women up to about 50 years of age. The progestogen-only pill may be an appropriate option in an older woman with declining fertility. The copper intrauterine device is an optimal method for parous women free of pre-existing menstrual problems. The levonorgestrel-releasing intrauterine system is considered the contraceptive method of choice for perimenopausal women with menstrual dysfunction. The woman should be provided with individualized advice so that she has a choice between the newer, effective, largely safe, reversible methods and sterilization.

“…Studies on these devices began in 1985, and they are approved for use in the European Union, China, and Indonesia. Research demonstrated they are highly effective and comparable to the TCu380A IUD (72). A multicenter, randomized, comparative trial found some benefits to the frameless IUD, including fewer pregnancies in the second through eighth year of use, fewer ectopic pregnancies, and fewer removals for pain.…”

New developments in long-acting reversible contraception: the promise of intrauterine devices and implants to improve family planning services

Fertility and Sterility

After decades of having the developed world's highest rates of unintended pregnancy, the United States finally shows signs of improvement. This progress is likely due in large part to increased use of highly effective long-acting reversible methods of contraception. These methods can be placed and do not require any maintenance to provide years of contraception as effective as sterilization. Upon removal, fertility returns to baseline rates. This article addresses advances in both software-improved use and elimination of barriers to provide these methods; and hardware-novel delivery systems and devices.
