2 Objectives:- To know the different types of contraception To know the failure rate & mechansim of action of each type To explain the side effects & contraindication for each methods of contraceptions

3 Classification Hormonal contraception # COCP # Progesteron only preparation as * POP *Injectable progesterone * Subdermal implants # Intrauterine devices (IUDs) * Conventional IUDs *Hormone releasing intrauterine system

4 Barrier methods Condoms Female barriers Coitus interruptus Natural Family planning Emergency contraception Sterilization as Female sterilization Vasectomy

5 The commonly used contraceptive method in UK are COCP then condom then vasectomy then IUCD. Faiulare rate of CC is due to failure of use rather than the product itself & the failure rate express per HWY, mean the no. of pregnancies one would expect to occur if 100 women were to use the method for one year

6 Contraceptin failure rate perhwy COCP POP 1-3 Depo provera Norplant Cu bearing IUD 1-2 Levonorgestrel 0.5 releasing IUD Male condome 2-5

7 The characteristics of ideal contraceptive 1) Highly effective 2) No SE 3) Independent of intercourse 4) Rapidly reversible 5) cheap, widespread availability 6) Acceptable to all cultures & religions 7) Easily distributed 8) Administration by health care personnel not required

8 COCP These pills contain both estrogen & progestern these taken for 21 days with 7 days pill free interval Mode of action of COCP 1) Inhibition of ovulation 2) Change in CX mucous characteristics, interfering with sperm transport 3) Alteration in tubal motility 4) Endometrial atrophy &impaired uterine receptivity.

9 Advantages of COCP:- 1)Menstrual cycle become more regular & menstrual blood is lighter & shorter period. 2) Less dysmenorrhea & less PMS. 3) Decrease incidence of IDA. 4) decrease incidence of benign breast lumps.

10 5) Decrease rate of functional ovarian cysts, endometriosis & acne, PID. 6) protect against endometrial &ovarian cancer Contraindications of COCP:- Absolute Contraindication are:- 1) IHD 2)CVA 3) Significant HPT 4) Arterial or venous thrombosis

11 5) Acute or severe liver dis 6) Pulmonary HPT 7)hyperlipidemia 8) pregnancy 9) focal migraine 10) estrogen dependant neoplasms as breast cancer 11) undiagnosed genital tract bleeding

12 Relative contraindication:- 1) generalized migraine 2) Long term immobilization 3) D.M, obesity, heavy smoking.

13 Side effects of COCP: 1) Minor S.E:- *Weight gain, fluid retenition& leg cramps *Headache, Nausea & vomiting. *Chloasma & greesy skin. *Mood changes, depression. *Loss of libido. * Mastalgia & brast enlargement. * Vaginal discharge, irregular bleeding * Growth of fibroid.

14 2) Serious S.E: * Venous thromboembolism * Arterial disease * Malignant disease Drug interaction with COCP # What to do when women missing a dose of COCP

15 Progestogen only contraceptions These include 1) POP 2) Injectable progestogen. 3) Subdermal implant. 4) Hormone releasing IUS Mechanism of action:- 1) It inhibit ovulation in high dose 2) Affect CX mucous & reduce sperm penetration 3) Affect endometrium making it thin & atrophic thereby prevent implantation

16 Side effects of progestogen only contraception:- 1) irregular VX bleeding or amenorrhea. 2) Premenstrual like syndrome. 3) Acne, breast tenderness 4) Functional ovarian cyst 5) Osteoporosis. 6) Risk of ectopic pregnancy.

17 POP It is taken everyday without a break they contian The 2 nd generation prog. Particular indications for POP :- * Breastfeeding * Older women * Presence of CVS risk factors * D.M Faiulare rate of POP is greater than that of COCP

18 POP

19 Injectable progestogen s These include medroxyprogesterone acetate 150 mg (depo provera) given every 3 month & Norethisterone enanthate 200mg given every 2 month, depo provera given by deep IM injection,it inhibit ovulation & it cause infrequent or scanty bleeding or amenorrhea. Particular side effect of depo provera:- # Delayed fertility #weight gain # Osteoporosis # Persistant menstrual irregularity.

20 Progestogen implants:- Norplant which consist of six silastic rods inserted Subdermally in inner aspect of upper arm under local anasthesia by a special trained person, it release levonorgestrel & last for 5 y, it is expensive,cause menstrual irregularity.

21 Intrauterine contraceptive device:- Types :- ## inert plastic device as lippes loop or saf- T coil, Dalkon shield they cause heavy & painful menstrual periods, they could be left in place until menopause ## Newer copper beering IUD they cause less menstrual disruption than the older plastic device, they licensed for 3-5 y of use, but many will last longer,possibly for up to 10 y ## Hormone-releasing IUDs as Levonorgestrel IUS (mirena), it is associated with dramatic reduction in menstrual blood loos.

25 Mechanism of action of IUCD:- All IUCD induce an inflamatory response in the endometrium that prevent implantation, Cu-bearing IUCD has atoxic effect on sperm that prevent fertilization, Hormone releasing IUS prevent pregnancy by a local hormone effect on CX mucous & endometrium. SE of IUCD :- 1) Increase menstrual blood loss 2) Increse dysmenorrhea 3) Increase risk of pelvic infection following insertion

26 4) perforation 5) Expulsion 6) Ectopic pregnancy Contraindications to IUCD:- 1) Previous PID. 2) Previous ectopic pregnancy. 3) Known malformations of uterus. 4) Copper allergy

27 Barrier Methods of contraception # Male condom:- It is one of the most popular method of contraception,cheap, widely available, free of side effect except for allergic reaction, they made of latex rubber,it protect against STD, most condoms lubricated with spermicidal cream or jelly. # Female condom:- made of plastic & thus less likely to burst, protect against infection, are expensive.

28 Female condom

29 # Vaginal diaphragm & CX cup:- They all use with spermicidal cream or gel, diaphragm are inserted prior to intercourse & should be removed no earlier than six hours later. Female barrier offer protection against ascending infection but can increase risk of UTI & VX irritation

30 Natural family planning This involve avoidance of intercourse during the fertile period of the cycle, fertile period is calculated by various techniques such as 1) changes in basal body temp. 2) Changes in CX mucous. 3) Changes in cx. 4) Multiple indices.,persona kits Lactational amenorrhea method(lam) for this method to be effective contraception, the mother should be fully breast feeder & be amenorrhiec&the age of her child less than 6m.

31 Coitus interruptus This is a widely practised & does not require any medical supervision, this involve removal of penis from the vx immediately before ejaculation take place, it is not reliable as pre- ejaculatory secretion may contain million of sperms thus emergency contraception should be available.

32 Emergency contraception Defined as any drug or device used after intercourse to prevent pregnancy,ec should be considered if unprotcted intercourse has occurred, if there has been failure of a barrier methode e.g aburst condom or if COCP has been forgotten. Types of EC:- 1) hormonal EC:- A combination of 100mg of ethinyle estradiol & 500 mg of levonorgestrel is taken twice, the two doses being 12 h apart & started within 72h of unprotected intercourse.

33 mechanism of action is believed to be prevention Of implantation due to endometrial shedding, SE N & V,failure rate is %. 2) IUD for EC:- A Cu bearing IUD can be inserted for EC,it is effective for 5 days following the anticipated day of ovulation, the IUD prevents implantation & the Cu ions exert an embryo toxic effect

34 Sterilization:- this is permanent method of contraception, they are chosen by older individuals who are sure that they completed their family &should take a consent from pt. Female sterilization:- this involve the a) mechanical blockage of both fallopian tubes to prevent sperms reaching & fertilizing the oocyte.

35 b) Hysterectomy c) Bilateral salpingectomy Female sterilization can be done by: 1) laparoscopically 2) minilaparatomy 3) colpotomy through posterior vx fornix

36 Techniques of female sterilization:- 1) Ligation 2) Electrocautery\ diathermy 3) Falope ring 4) Clips 5) Laser

37 Female sterilization

38 Complications of female sterilization:- 1) Anasthetic complications 2)Damage to intraabdominal organs 3) Ectopic pregnancy 4) wound infection 5) Menstrual disorder 6) failure

39 Vasectomy:- this involve division of vas deferenson each side to prevent release of sperms during ejaculation, it is technically an easier,quicker & performed under local anesthesia, vasectomy is not effective immediately so men should do SFA 12 wk &then 16 wk to check presence of sperm

40 If 2 consecutive samples are free of sperms then the vasectomy can be considered complete & alternative method of contraception must be used until that time. Techniques for vasectomy:- 1) Ligation or clips 2) Unipolar diathermy 3) Excision

41 4) Non scalpel vasectomy 5) Silicone plugs,sclerosing agents. Complications of vasectomy:- 1) wound infection 2) Heamatoma 3) Sperm granuloma 4) Antisperm AB 5) Some suggest a linkage between vasectomy & testicular & prostatic tumor
