ADVANTAGES
|
DISADVANTAGES
|
May accidentally break or slip off
during coitus.
|
|
Inadequate sexual pleasure.
|
|
Easy to carry, simple to use and
disposable.
|
To discard after one coital act.
|
Useful where the coital act is
infrequent and irregular
Protection against sexually
transmitted diseases, e.g. gonarrhoea, Chlamydia, HPV and HIV
|
|
Protection against pelvic
inflammatory diseases
|
Failure rate – 14(HWY); 3(HWY) when
used correctly and consistently.
Precautions:
- To use a fresh condom for every act of coitus.
- To cover the penis with condom prior to genital contact
- Create a reservoir at the tip.
- To withdraw while the penis is still erect.
- To grasp the base of the condom during withdrawal.
Fig 1.4 Methods to stop Female Pregnancy
FEMALE CONDOM (FEMIDOM)
It gives protection against sexually
transmitted disease and pelvic inflammatory disease. It is expensive. Failure
rate is about 3-5/HWY.
VAGINAL
CONTRACEPTIVES:
The cream or jelly is introduced high
in the vagina . Foam tablets (1-2) are to be introduced high in the vagina at
least 5 minutes prior to intercourse.
VAGINAL
CONTRACEPTIVE SPONGE (Today)
It is made of polyurethane impregnated
with 1gm of nonoxynol-9 as a spermicide. Nonoxynol-9 acts as a surfactant which
either immobilizes or kills sperm. The sponge should not be removed for 6 hours
after intercourse. It’s failure rate is about 10/HWY.
RHYTHM
METHOD:
This method is based on identification
of the fertile period of a cycle and to abstain from sexual intercourse during
that period.
The first unsafe day is obtained by
subtracting 20 days from the length of the shortest cycle and last unsafe day
by deducting 10 days from the longest cycle.
Failure rate 20-30 (HWY)
Not applicable during lactational
amenorrhoea or when the periods are irregular
COITUS
INTERRUPTUS:
It necessitates withdrawal of penis
shortly before ejaculation. Accidental chance of sperm deposition
into the vagina. Failure rate – 20(HWY)
BREASTFEEDING,
LACTIONAL AMENORRHOEA (LAM)
Thus during breastfeeding, additional
contraceptive support should be given by condom, IUCD or injectable steroids
where available to provide complete contraception.
When the women is full breastfeeding, a
contraceptive method should be used in the 3rd postpartum month and with partial or no breastfeeding, she
should use it in the 3rd postpartum week.
full breastfeeding and amennorhoehic - risk of pregnancy <2% in first 6 months
general
--- risk of pregnancy 1- 10%
INTRAUTERINE
CONTRACEPTIVE DEVICES(IUCD)
Cu T200B ------ replaced every 3 years
Cu T 380A:- ----Replacement every 10 years
Multiload Cu 250:- replacement every 3 years. Multiload Cu375 replaced every 5 years
Levonorgestrel intrauterine system (LNG-IUS):-
n replaced every 5 years.
MODE
OF ACTION:
Video 1.1 Fertility and Treatments
- Biochemical and histological changes in the endometrium
- Copper devices – Preventing implantation through enzymatic interference.
- There may be increased tubal motility
- There may be impaired sperm ascent
- Levonorgestrel-IUS(Mirena) – It induces strong and uniform suppression of endometrium.
- Cervical mucous becomes very scantly.
- I is preferable to insert 2-3 days after the period is over.
CONTRA INDICATION FOR IUCD INSERTION
1)MENORRHAGEA
2)PELVIC INFECTION(PID)
3)DYSMENORRHOEA
factors related to its discontinuation
(10%-15%)
Pain, abnormal uterine bleeding and PID
SPONTANEOUS EXPULSION – The expulsion rate is about 5 percent.
FAILURE RATE–
The pregnancy rate with the device in situ is about 2 per 100 women years of use. Lowest
pregnancy rates are observed with Cu T 380A (0.8-HWY) and LNG-IUS (0.2 – HWY).
Fig 1.12 Contra indication for insertion
- 3rd generation IUCD(Cu T 380A, Multiload Cu375 and Levonorgestrel-IUS(Mirena)
- Higher efficacy with lowest pregnancy rate (less than one pre 100 women years).
- Longer duration of action (5-10 years)
- Low expulsion rate and fewer indications for medical removal.
- Risk of ectopic pregnancy is significantly reduced (Cu T-380A and LNG- IUS:0.02HWY)
- Non-contraceptive benefits specially with LNG-IUD
- Can be used as an alternative to hysterectomy for menorrhagia, DUB.
- Apart from the use of Cu T as a contraceptive, it is used following synaecolysis.

·
Breakthrough

Amenorrhea:
Post pill amenorrhea of more than 6 months duration occurs in less than 1 percent cases. The association is casual not casual .it is usually more in women with per-existing functional menstrual disorders.

Hypertension: Current low dose COC5
rarely cause significant hypertension. Pre-existing Hypertension is likely to
be aggravated.
VASCULAR COMPLICATIONS (OGN):
Venous thromboembolism (vtm) - the overall risk is to the extent of 4-6
times more than the non –users .pre-existing hypertension, diabetes , obesity
and elderly patient (over 35 specially with smoking habits ) are some of the
important risk factors ethinyl oestrodiol
in preference to menstranol and the reduction of the dose of the oestrogen
compound to 20 ug in the pill markedly reduce the incidence
Plasma lipids and lipoproteins are increased .total cholesterol and
triglycerides are increased .Preparation with more selective, lipid friendly
and third generation progestin’s namely desogestrel, gestodeone or norgestimate,
HDL Level is some what elevated .
VITAMINS AND MINERALS:
Vitamins b6,b12,
folic acid ,calcium , manganese, zinc and ascorbic acid levels are
decreased while vit a and vit k levels
are increased.
INJECTABLE PROGESTINS:
NET –EN IN A DOSE OF 200 MG GIVEN AT TWO – MONTHLY INTERVELS.DMPA 150 mg three monthly intervals.
NET –EN IN A DOSE OF 200 MG GIVEN AT TWO – MONTHLY INTERVELS.DMPA 150 mg three monthly intervals.
Mechanism of action :
1) Inhibition of ovulation by suppressing the mid cycle LH Peak
2) cervical mucous becomes thick and viscid therapy prevents sperm penetration
3) Endometrium is atrophic preventing blastocyst implantation

Advantages :
1)it eliminates regular medication as imposed by oral pill
2) it can be used safely during lactation.

There is chance of
irregular bleeding and occasional phase of amenorrhea. Loss of bone

observed when there is failure of emergency contraception
Mode of action
·
Ovulation is either prevented or
delayed when the drug is taken in the beginning of the cycle
·
Fertilization is interfered
·
Implantation is prevented as the
endometrium is rendered unfavorable.
·
Interferes with the function of corpus luteum or may
causes luteolysis.
Draw backs:
Nausea and vomiting are much more intense with
oestrogen use
Copper IUD:
Introduction of copper IUD within a maximum
period of 5 days can prevent conception following accidental unprotected
exposure .this prevent implantation.
Anti progesterone:
Anti progesterone binds competitively to
progesterone receptors and nullifies the effects of endogenous progesterones.
PERMANENT METHODS
The operation done on
male is vasectomy and that on the female is tubal
occlusion, or tubectomy
occlusion, or tubectomy
VASECTOMY
Advantages:
