3- Introduction
- At the beginning as you know it is a happiness
for every parents to have a baby , but in the
same time it is very important to put in mind all
other factors that may effect the family life
either health , economical or even social
problems ,which increase in cases of a large and
uncontrolled number of family members , from this
point of view the need for a way to control the
number of birth was established , to improve the
population life-style - Our responsibility as pharmacists appear in
development and searching for different
techniques to control pregnancy ,and we will
talk today about one of this ways and its
development
4What is an ( IUD ) ?
- It is a small, flexible, plastic device that
contains either metal e.g. copper or hormones
e.g. progesterone and is inserted into the uterus
to prevent pregnancy.
5How dose it work ?
- It may
- -Block sperm from reaching or fertilizing the egg
- -Make the lining of the uterus unsuitable for
implantation . - -interfere with the ovulation process
- We do not know which of these actions is most
important for preventing pregnancy and most
likely all of them work together.

7Types of ( IUD ) There are two main categories
of IUDs
- 1. Medicated These forms of IUD use hormones or
metals to prevent conception. progesterone and
Copper plated IUDs are considered medicated
because they have abilities to hinder
fertilization. - 2. Non Medicated This category includes all
other forms of IUD no matter shape or size.
8Advantages and the Disadvantages of ( IUD )
- Advantages
- - Once inserted , remain in place .
- - Remains effective while in place.
- - it prevents pregnancy for long period
- - does not interfere with sexual activity.
- Disadvantages
- - May cause bleeding and cramping .
- - Increased risk of octopic pregnancy.
- - Doesn't prevent sexual transmitted diseases.
- - it is not recommended for women who have heavy
or long period
9 What is the history of (IUD) ?
- Camel riders in the Middle East are the first
recorded users of the IUD or Intrauterine
Device. It was common knowledge that if you
placed small stones in the uterus of your camel,
it would not become pregnant even during its
periods of high sexual activity .
10Hippocrates, the original Greek doctor, also
wrote small piece that could be put into the
uterus of a woman with the help of a small tube
can prevent pregnancy .In 1909 a German
physician named Richard Richter began to build
IUDs from small bronze rings and silk thread.
Richter, as well as many other doctors versions
of the IUD was too large for widespread use and
caused painful infections.
11 In 1930, Ernest Grafenberg improved Richter's
idea making the contraptions smaller, avoiding
most infections and making the device more
comfortable. By the early 1960s many other
forms/designs of IUD were invented and were
constructed of safer materials . - Since 1998
worldwide, several new intrauterine devices
(IUDs) are under development or in the early
marketing phase.
12- These new devices contain various modifications
designed to improve patient continuation and
physician satisfaction. Modifications include
those designed to facilitate easier insertion and
removal, decrease the rates of accidental
expulsion, and reduce complaints of pain or
bleeding

16What are the most cu ( IUD ) used today ?
Today two types of cu IUD are used mostly
Multiload (left) and cupper T (right)
17- What is the hormonal (IUD) used today?
- Late last year the FDA approved the intrauterine
device (IUD) Mirena. Mirena is a T-shaped that
releases small amounts of the hormone
(levonorgestrel) to block conception, Mirena only
needs to be replaced once every five years. The
others, in contrast, must be changed yearly. - A new IUD available in Europe US uses a
synthetic hormone to achieve a high rate of
long-acting contraception.

19WHAT ARE THE NEW DEVELOPMENT IN ( IUD ) ?
- Developers are designing devices to address the
disadvantages issue by modifying IUD size, shape,
and flexibility. - At least six new devices are under development,
or have recently been introduced, outside the US. - These devices include
20ICFD Gynefix Multiload mark 2 Soft-T Fincoid350 Cu safe 300
21- CuSafe 300The CuSafe 300 is a T-shaped copper
IUD with flexible, uniquely shaped arms. - Both ends of the device's transverse arms curve
inward to reduce uterine tissue irritation. In
addition, its mono filament tail is welded into
the shaft, instead of knotted, to reduce
ectocervical abrasion - device's flexible design facilitate easier ,less
painful insertion and removal, aslo the curved
"fundal-seeking" arms resist expulsion. - carries a recommended life span of 5 years.
- Advantages in comparison to copper T 380A IUD
- the inserter is about one third smaller than that
of the copper T 380A IUD. - These improvements should make the CuSafe 300
easy to insert and remove. - pain and bleeding occurred significantly less
frequently among CuSafe IUD users, also the
CuSafe had low and statistically significant
decrease rates of pregnancy and expulsion
22- Fincoid-350
- The Fincoid-350, devised in Finland, is also
designed to resist accidental expulsion. - The IUD has a plastic skeleton comprised of two
parts curved horizontal arms, and a copper
coated vertical stem. The resultant movable joint
easily constricts and expands with uterine
contractions, adjusting to variations in uterine
size and shape. The Fincoid-350 comes in two
sizes standard and short.
23- Sof-T
- The Sof-T, manufactured and approved for use only
in Switzerland, is a copper IUD with a unique
shape to enhance effectiveness. The device has
soft, flexible knobs, or occlusion bodies, on
each end of its flexible transverse arms. These
knobs theoretically block the entrances into the
fallopian tubes.Two dimensional ultrasound must
be used for insertion , however, to ensure exact
placement of the device. The device's potential
ability to occlude the fallopian tubes could, in
theory, reduce the incidence of tubal infection
and ectopic pregnancy.On the other hand, the
knobs may incompletely block the fallopian tubes
and result in higher rates of ectopic
pregnancy.About 1,200 women currently wear the
device. Limited data indicate that the annual
expulsion rate ranges between 0.3 and 3.5,
removals for pain or bleeding range from 0 to
1.4
24- Multiload Mark II
- The Multiload Mark II is an updated version of
the original Multiload 375 (ML 375). - The original device has a record of
dependability, with low patient cessation rates
due to pregnancy, expulsion or bleeding and pain.
The ML 375 has been associated with problematic
insertions, however, because its arms do not fit
into the inserter the arms are open during
insertion, making placement more difficult.the
new inserter's diameter is smaller than the
original model. - In addition, the inserter has three other
improvements its design prevents the IUD from
getting pushed beyond the inserter it can
function as a uterine sound and it has a one
handed expulsion action. - These innovations may help limit the risk of
uterine perforation.
25- GyneFix
- The GyneFix, a "frameless" IUD, consists of six 5
mm copper sleeves. This device was originally
called the Cu-Fix 390, then later the FlexiGard
330. - The device has undergone 10 years of testing and
several modifications to its inserter and
anchoring mechanisms. The upper and lower copper
sleeves are crimped onto the suture thread to
prevent slippage. - The proximal end of the suture contains a knot
that is pierced 1 cm into the fundal myometrium
to anchor the device into the uterine muscle. - Variations of the device for postpartum use
include a larger knot and a cone shaped
biodegradable tip that help anchor it securely.
26- Due to its frameless design, flexibility, and
minimal presence in the uterine cavity, the
GyneFix is associated with few expulsions. In
addition, the device has a high continuation rate
at 1 year (90) due to few removals for
complaints of bleeding or pain.Effectiveness
depends upon proper insertion technique because
the device must be securely anchored into the
uterine myometrium or it will be expelled.In
addition, the device has very low expulsion rates
among nulliparous women.
27- Intracervical Fixing Device (ICFD)
- The intracervical fixing device differs
substantially in both construction and placement
from other IUDs. - The device consists of a rod shaped, copper
coated polyethylene frame that is about 4 cm long
with a 5 mm projection at the distal end. Through
this projection, the ICFD is anchored (fixed) to
the inner cervical wall using a modified
tenaculum. Investigators believe the ICFD's
anchoring mechanism could be improved. - Better anchoring mechanisms could help to prevent
expulsions. One potential advantage of the device
is that the insertion procedure is not blind. In
addition, because of the intracervical location,
the device will likely be associated with less
spotting, bleeding and pain.
28- Conclusion
- Developers are designing new IUDs with
modifications to help enhance patient and
physician acceptance. - Modifications to the devices aim to decrease
removals due to pain and bleeding, make insertion
and removal easier, and limit the risk of
expulsion and prolong the life span of the device
