1. Intrauterine contraceptive devices (IUCDs) include non-medicated, copper-containing, and hormone-containing devices.
2. Copper IUCDs like CU-T 380A release copper ions that create an inflammatory response and changes in the endometrium to prevent implantation. The levonorgestrel IUCD releases the hormone progestin to suppress the endometrium.
3. IUCDs are highly effective long-acting reversible contraceptives that also provide non-contraceptive benefits like lighter periods. Their failure rates are much lower than other methods. Complications are generally minor.
4. Device Description
CU-T 380A contains 380 mm square of copper.
(vertical stem 314mm sq and each arm 33mm sq)
• Copper is radio opaque, additional barium
sulfate is incorporated in the device.
• Device is replaced 10years
• It is used of synecolysis to prevent adhesion
formation after adhesiolysis in Asherman’s
Syndrome
5. Multi load CU-375:
• It has 375 mm sq surface area of copper wire
• No introducer and no plunger
• Replaced every 5 years
Multi load CU-250:
• Emits 60-100mcg of copper per day
• Replaced every 3 years
6. Levonorgestrel Intrauterine system:
• T- shaped with polydimethylsiloxane
membrane around the stem which acts as a
steroid reservoir
• Total amount of LNG is 52mg
• Daily 20mcg is released
• To be replaced every 5 years
• It has many non- contraceptive benefits
7. Mechanism of action
• Biochemical and histological changes in the
endometrium
• Increased tubal motility
• Endometrial inflammatory response
• Copper initiates release of cytokines which are
cytotoxic. Ionised copper prevents blastocyst
implantation through enzymatic interference
• LNG IUS : Suppression of endometrium, scanty
cervical mucus
8. Advantages
• Contraception
• Prevents synechiae formation
• Third generation IUCDs – higher efficacy,
longer action, less expulsion, decreased risk of
ectopic pregnancy, decreased risk of PID
• With LNG IUS- decreased menorrhagia,
dysmenorrhoea, premenstrual tension
syndrome, treatment of endometrial
hyperplasia, endometriosis, adenomyosis
