contraception methods- new and old, compiled together.

1. Contraception
Dr. Saumya Prasad
M.S (ObGyn)

2. India was the first country in the
world to have launched a National
programme for Family Planning in
1952.
“The ideal family – two parents, two
children”
The red
triangle is
India’s family
planning
symbol.

3. Need for contraception
21 % of all pregnancies resulting live births are
unintended
Around 2/5th of all pregnancies are unintended
If unmet needs of contraception is met then we can
avoid:
55 million unwanted pregnancies
22 million fewer abortions
90,000 fewer maternal deaths

4. Reasons of unintended pregnancies:
Unawareness
Use of traditional methods
Side effects
High cost
Difficult mode of delivery
Fear of irreversibility of fertility

5. 1. Safe
2. 100% effective
3. Free of side effects
4. Easily obtainable
5. Affordable
6. Acceptable to the user
7. Free of effects on future pregnancies

9. Latex Condoms
• Latex condoms are the most common type of
condoms
• The main advantages of latex condoms are that
they can be stretched a lot before it breaks
• That means it is good at preventing the semen
from going through the condom
Failure rate
Typical use 12%
Perfect use 3%
10

10. Polyurethane Condoms
• Polyurethane condoms are also very common
• These are very similar to latex condoms in size
• They have a longer shelf life than latex condoms
• They have less allergic reactions to them
• Can be used with oil based lubricant
• These condoms also prevent STI’s
• Slip more, break more
• More expensive
11

11. Male Condoms
Advantages Disadvantages
Readily available Can cause hypersensitization
Suitable for all age group Difficult to dispose in villages
Harmless method
Prevention against STI RR= 0.1%
If used in later half of pregnancy,
reduces risk of amniotic fluid infection
If used >5years, reduces risk to
cervical intraepithelial dysplasia
MEC
Category 4 None
Category 3 Latex allergy
High risk pregnancy in c/o
failures 12

12. Female Condoms
• This type of contraceptive is put into the vagina
before having sex
• It has two ends with rings on them
• The end that goes into the vagina has a closed
rim
• The end that stays outside has an open rim
Failure rate
Typical use 21%
Perfect use 5%

13. Occlusive caps
Are not sperm proof mechanical barriers
Retain spermicide with cervical os
Spermicide must be used
Usually manifacured by rubber
Vaginal
diaphragm
Cervical
cap
Vault cap Vinule cap
14

14. Vaginal Diaphragms
• This is a dome shaped object that is also made
of rubber.
• It fits around the cervix, preventing the sperm
from being able to enter the uterus
• This is used with spermicide
• Available in diff sizes, 60,65,70,75mm
• 3 types- flat type, coil type, arching type
Failure rate
Typical use 16%
Perfect use 6% 15

15. Cervical Caps
• Rubber caps that are inserted into the vagina
and fits around the uterus
• This blocks the passage way for sperm to
enter the uterus
• This is used with spermicides.
• 3-4 sizes available- 21 to 31 mm.
• Ex- ortho cervical cap, miller cervical cap
Failure rate
Typical use Nulliparous-16%
Parous- 32%
Perfect use Nulliparous- 9%
Parous-26%

16. Vault cap
Rubber or plastic cap
50-75mm in size
Replaced by diaphragm
Ex- dumas
Vinule cap
Type of cervical cap
Used in women with
prolpse
When diaphragm
cannot be retained
Ex- vinule pessary
Disadvantages of occlusive
caps
Spermicide can cause irritation in
the vagina
If the cap is not removed well in
time, vaginal discharge may
present
Allergic reaction due to silicone
cap
TSS is a rare complication

• It is saturated with nonoxynol-9
• Nonoxynol- spermicide action
• Blocks the cervix and absorption of semen
• Acts for 24hrs

40. IUB and SPHERA
The IUB is a revolutionary new product
in the intrauterine contraception field.
The IUB is a three-dimensional, ball-
shaped device that is inserted into the
uterine cavity to prevent pregnancy.
Its efficacy is similar to current copper
intrauterine devices (IUD), however its
insertion is simpler, its improved safety
profile has been demonstrated in a clinical
trial and it is expected to offer a better
quality of life over current devices

41. Fertility regulating vaccine
Anti Hcg vaccine
Uses tetanus toxoid diphtheria as carriers
The antibodies produced by the anti hcg vaccine neutralize hcg from
fertilized egg leading to endometrial shedding with loss of fertilized
ovum
However the initial results are not very promising

44. REMOTE CONTROL CONTRACEPTIVE CHIP

45. Conclusion
India's public sector programme claims to provide a
“cafeteria approach” with a “basket of choices”.
The method-mix in this programme includes five official
methods :
1. Female sterilisation,
2. Male sterilisation
3. Intrauterine contraceptive device (IUCD)
4. Oral contraceptives
5. Condoms
